01052008 1603UTC Delfi_c3 packets copied
by Mark L. Hammond 01 May '08

01 May '08

As per subject--Delfi-c3 copied on 145.930 on a noon-time pass over Eastern US, FM05pj at N8MH. This was a descending pass! (I wasn't at home, so no observations to make). Question---is the packet count in the upper left region cumulative for the entire database? Or is it just for my station during the recent session? I'm tending to think it's cumulative, and that lower right packet count is for that RASCAL session. Can anybody comment/confirm? Thanks and 73, -- Mark L. Hammond [N8MH]

DELFI C 3
by Luc Leblanc 01 May '08

01 May '08

The 0400Z pass was all OK even if it was a low one 20 packet decoded and DELFI was in full illumination since 0342Z a good 15 minutes before the pass and everything seems normal. I guess the problems appears just went the satellite is emerging from eclipse and that the power is just starting to flow in. I will try to recheck in the evening pass if i got the same results as yesterday evening. At the end of the pass another carrier with doppler appear i try to check who was the culprit but VO-52 who is on a similar orbit was on the other side of the earth. I run a simulation on all the other active satellite around 0400Z to see which one will be the best candidate but none of them was in range!!! Another phantom of the opera signal? I just hope one of the other 8 cubes does not also share the same downlink frequency! "-" Luc Leblanc

Ham Radio Deluxe with linear xpndrs?
by Dave hartzell 01 May '08

01 May '08

Just wondering if anyone is using Ham Radio Deluxe with the linear birds (e.g. VO-52). While it seems to work fine with the FM sats, I think there may be an issue adjusting the frequencies to find oneself in the passband. For example, I can manuually tune the RX downlink while TX'ing and find myself, but shortly after the offset gets reset to the calculated frequency.... Thanks and 73, Dave n0tgd

Delfi-C3 heard over TN, FINALLY
by Alan P. Biddle 01 May '08

01 May '08

After a couple of days with nothing heard, I got a great pass today, with ~400 blocks of data uploaded. AOS and LOS were within a couple of seconds using the operations page keps. After an initial tweak, SATPC32 tracked the frequency within about 150 HZ through the whole pass. Another sign that the keps are good.

Delfi-C3 status update 1 May 2008 09:55 UTC
by Wouter Jan Ubbels 01 May '08

01 May '08

Hi all, another status update on Delfi-C3: 1. During the pass of 09:30 UTC over Europe, we have performed successful database dumps again, some of you may have heard these since the frames sound quite different compared to normal housekeeping / payload frames. These frames are also captured by RASCAL, displayed in the terminal and uploaded to our server 2. During this same pass, we have successfully switched the spacecraft to its primary radio on 145.870MHz temporarily, after this switch, the satellite came back on on the 145.930MHz downlink. Telemetry indicated that the primary radio on 145.870MHz is healthy and working fine so that is good news. Note that the satellite will normally transmit on 145.930MHz for the time being, unless we command her to go to 145.870MHz. This might occur more in the coming days when the s/c is in range of our groundstation, so listeners in Europe might want to check the 145.870MHz transmitter also when the 145.930MHz transmitter shuts down. We have noted that the 145.870MHz transmitter is a little (1kHz) low in frequency so actually on 145.869MHz. 3. Yesterday (April 30) we were able to successfully command on our backup command uplink so we have both command uplinks working nominally at this moment. 4. We are currently investigating the rotational behaviour of the satellite, your observations w.r.t. spin rate / signal strength are more than welcome, combined with telemetry we should be able to fully assess how the s/c is rotating. We suspect that this may actually give a clue to the TX dropouts experienced. 5. We have successfully gathered raw data from the wireless sun sensor payload 6. Note that we have locked the bootcounter value so it will always display 2273 from now on until we unlock it again 7. Although TLE's for object #32787 are listed on our webpage, we are not entirely sure that this is in fact Delfi-C3. We probably won't have confirmation until after a day or 3-4 when the satellites have separated a bit more. For now, object #32787 should be fine for tracking though, but your observations w.r.t. AOS / LOS times are welcome 8. Following the report from VE2DWE about the TX sounding distorted, we would like to ask everyone to record a wav if possible when this phenomenom is heard, you can send the wav files to missioncontrol(a)delfic3.nl . Our inbox has no problem with large file sizes. 73 on behalf of the Delfi-C3 team Wouter Jan Ubbels PE4WJ

Re: Delfi-C3 RASCAL tuning & TLE's
by G0MRF＠aol.com 01 May '08

01 May '08

Hi. Here in London I can only manage to monitor evening passes. All of these have Delfi-C3 emerging from eclipse shortly before, or during the pass. So far it's been there on every occassion. I managed to get a little telemetry last night, but only enough to show the computer has had 2216 attemps at booting up. With about 40ish orbits that averages 50 tries per orbit So, immediately exiting eclipse seems the best time to get good results. When starting RASCAL you appear to need 3 consecutive packets on frequency to sync the receive software and to decode the last packet as a line of data.

Sierra Vista AZ hamfest demo, Saturday (3 May)
by Patrick STODDARD (WD9EWK/VA7EWK) 01 May '08

01 May '08

Hi! On Saturday, 3 May 2008, the Cochise Amateur Radio Association (CARA) will host the annual Larry Warren Cochise Hamfest in Sierra Vista, Arizona (grid DM41vm). The hamfest starts at 7am local time (1400 UTC). CARA has more information about the hamfest at: http://www.k7rdg.org/2008hamfest.html As part of the hamfest, there will be an AMSAT table with merchandise and satellite demonstrations. Local hams Jeff K7WIN and Bill K7WJS, assisted by Larry W7LB from Tucson and me (driving down from Phoenix), will be there to answer questions related to amateur satellites and also have on-air demonstrations using the AO-51 and SO-50 satellites during the morning. Thanks to the CARA, our on-air demonstrations will be done using the club's callsign K7RDG. If you hear us on the Saturday morning AO-51 and SO-50 passes, please give us a call. Between passes, we will be reachable on K7WIN's 70cm repeater, via IRLP and EchoLink. You may reach us on IRLP using node 4754 and on EchoLink at node 4249. If in the area, K7WIN's repeater is on 449.725 MHz, with a -5 MHz offset and 179.9 Hz PL. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Tuning AO-16
by Alan Cresswell 01 May '08

01 May '08

Bob, Can you hear the AO-16 carrier on the downlink?. It is not strong but still quite noticeable (at least in this part of the world). If you zero beat to the carrier then you are in the right spot to then select either Upper or Lower sideband and you should then resolve the SSB OK. Good luck Alan ZL2BX

Cute 1.7+APDII and SEEDS over West Malaysia
by Sion Chow Q. C. (9W2QC) 01 May '08

01 May '08

Dear All, Below is the recording of this morning's pass of Cute-1.7+APDII and SEEDS over West Malaysia. Listened out for Delfi-C3 but nothing heard on both frequencies. Time: 1115 Local, 0315 UTC Elevation: 27 degrees Tracking Object-J http://www.9w2qc.net/amsatbb/cuteseeds01may1115.mp3 The first 6 minutes are Cute-1.7+APDII CW telemetry and the remaining of the file is SEEDS telemetry. Looks like it is really time to put another UHF yagi up the rotator for simultaneous RX of Cute-1.7+APDII and SEEDS. :-) Good luck to the teams involved and hope that the telemetry is useful. 73, Sion Chow Q.

SEEDS reception...
by Mark Vandewettering 30 Apr '08

30 Apr '08

Well, I didn't get anything from Delfi C3 on its first pass over the West Coast, but I had heard that some people managed to get some signals from some of the other cubesats, so I set up for SEEDS on the low, second pass. Maximum elevation was only 9 degrees, and I recorded the pass with my FT-817 and a little voice recorder, tuning the doppler by hand. My morse skills are feeble, but even I could pick out the SEEDS in the telemetry stream. Audio is here: http://brainwagon.com/images/seeds.mp3 Congrats to all the teams! Mark

Cute-1.7 Follow-up Report
by Hiroki Ashida 30 Apr '08

30 Apr '08

Hello All, I'd like to inform you the current status of the Cute-1.7 + APD II. First of all, thank you very much for many kind cooperations! We are grateful to you all. According to the informations you gave us, now we believe that our satellite is normal. Using an engineering model, we confirmed the same phenomena, which has different battery voltages between one in CW frame and another one in FM packet, occurs on rare occasions. But in fact, there's no voltage reduction because the frequency of the CW beacon is very stable. We are going to operate it carefully, but no more an emergency mode. Thanks again!

I refresh my Orbitron KEPS Mak and i just hear DELFI C 3 very loud but there is another problem who come out. The audio was very unstable the tone frequencies where not stable and some distortion seems to appears during the data transmissions making RASCALS completely unable to decode even a single packet. Theses tones distortions gradually increased up to a point the transmitter shuts down. The tone pointer on RASCALS was moving wild smashing both side limit of the scale and it was not what i got the first time i decoded my first packets. Why the tone frequencies are no more stable even with doppler correction remain a mystery but surely the control team will come up with some explanations as they seems to be aware of this behaviour.

Dish Controller Project Solicitation?
by Robert Bruninga 30 Apr '08

30 Apr '08

We are looking for someone to design a microcontroller for our Naval Academy 40 foot dish. The controller will be a small rack mount box with serial input port suitible for taking AZ/EL commands from any of the popular Tracking Programs. The output is an analog voltage from +/- 10 volts to drive the 75 HP hydraulic system as a closed loop PID controller. There are a few other discrete TTL signals involved to get the hydraulics running and to handshake with the various interlocks. The device will have front panel LCD readouts and buttons. See the web page where I am assembling ideas: http://www.ew.usna.edu/~bruninga/12m-dish.html There will be two such boxes. One at the dish and the other almost a mile away at the control station. One is the controller and the other is just a remote display. They are connected by a serial port operating at 9600 baud with the remote one also connected to whatever tracking program is controlling... This dish is an X/Y dish and not AZ/EL (X goes East and West, and Y goes North and South), but a few trig conversions can easily manipulate between the two. The optical shaft encoders are 16 bit+ and operate at 9600 baud serial also but at RS422 levels. We have been using the one I built 10 years ago that I programmed in Qbasic and runs on a PC104 bus DOS card. All of the TTL level interfaces are there... But I just don't have the time or patience any more to do this again... So we are going to contract it out. This will be a full blown Government procurement with all the overhead and other baggage. So only serious respondents should consider this. We have not yet written a formal spec, or procurment package. But this is just a heads up that we will be putting this together soon, since this must be completed this summer. Nothing in this email or web page in any way obligates the government to proceed with this project. It is just a way of getting out the word that we are looking for a solution to replacing our aging controller. Bob Bruninga US Naval Academy Satellite Lab

(new word, just invented by me :-)) You recording is much more normal. I used std CW mode, what did you use ? The other satellite is most likely COMPASS, which is on the same frequency.

Sounds like a good idea! I was at SVHFS last week and there was a lot of discussion and design effort toward GPS derived frequency control for EME and microwave roamers. -- Joe Leikhim K4SAT "The RFI-EMI-GUY"© "Treason doth never prosper: what's the reason?

Delfi-C3 status update 30 April 2008 08:00 UTC
by Wouter Jan Ubbels 30 Apr '08

30 Apr '08

Hi all, Delfi-C3 is in orbit and healthy, despite some minor issues, please find a status update below: 1. Telemetry indicates that all solar panels and antennas have deployed properly 2. Telemetry indicates nominal values for all housekeeping values 3. We have already obtained payload data, and have been able to generate IV curves of the Thin Film Solar Cell experiment, note that those uring RASCAL can view the IV curves by clicking Options-->show IV curves in RASCAL. 4. The spacecraft is operating in science mode, we have had one orbit in emergency mode, which was most probably due to a databus issue 5. Up till now we have received 7000+ (!) frames from amateurs using RASCAL around the globe, amazing, thank you all so much!! 6. We have verified command uplink functionality yesterday, and were able to command the spacecraft today on the low elevation (4.9max) pass over our GS at 0737UTC 7. The spacecraft has decided to consistently use the backup radio on 145.930MHz for its telemetry downlink, we were able to request a full on-board database dump while in range of our groundstation yesterday and analysis of the database confirms this. We currently have a good understanding why this is the case. We will try to switch downlinks to the primary radio on 145.870MHz during the next good pass over our GS, so amateurs in Western Europe might want to check that frequency also and might experience intermittent telemetry while we are commanding. Note that we suspect that the TX frequency could be 1 to 2 kHz lower on this radio, so tuning around slowly is the best strategy. 8. The spacecraft seems to have an issue with the downlink TX switching off into the orbit, which is the reason while Delfi-C3 has not been heard on most descending passes over VK/ZL, we think we have a good understanding of why it is. The TX itself is fine, but it switches off automatically when it does not get data from the OBC for a certain amount of time. We are working on resolving this issue. This also happened during the pass over our GS at 0737 UTC but we were able to command it back on. For those in Western Europe we would like to ask to keep tracking Delfi-C3 even if you can not hear it at first, as we will try to turn the TX back on as soon as we notice that it has been turned off. 9. Thank you all for your observations on the spin rate, these are really helpful! We currently think that the spacecraft is tumbling with approx 10deg/second, which corresponds to a 36 second period. Since the s/c downlink antenna is almost truely circular, polarization sense can change from RHCP to LHCP completely depending on s/c orientation, we use circular antennas on our GS as well, and when we switch to the opposite polarizaiton sense the signal is wiped out completely, switching back gives solid copy with strong sigs. 10. NORAD object E #32787 seems to match best thanks for all your observations and efforts so far! 73 on behalf of the Delfi-C3 team, Wouter Jan Ubbels

Delfi-C3 RASCAL tuning & TLE's
by Wouter Jan Ubbels 30 Apr '08

30 Apr '08

Hi all, we have added a section to our RASCAL tuning guide in order to make achieving sync in RASCAL easier, see http://www.delfic3.nl/index.php?option=com_content&task=view&id=94&Itemid=1… I have also included it in this mail for clarity: Tuning can sometimes be difficult, in the presence of Doppler shift, fading due to polarization changes, frequency offset due to temperature of the spacecraft oscillators and there is the possibility that the Costas Loop indicates a false sync because of lock on one of the signal's sidebands. If possible, you can use a waterfall display in software like MixW running parallel to RASCAL which will give you an indication of the centerfrequency. During transmission of AX.25 flags, the actual carrier frequency is the highest peak in the spectrum, with a couple of sidebands exactly 150Hz apart, looks like a comb. Now, using the waterfall display, tune such that this highest peak corresponds to 1600Hz +/-100Hz, in order to achieve sync. Furthermore, Delfi-C3 is now listed on celestrack with identifier DELFI-C3 , as object #32787, these TLE's are also on our mission ops page. Today we also verified that our backup command receiver functions well, we are still working on the TX drop out issue. 73 on behalf of the Delfi-C3 team, Wouter Jan Ubbels PE4WJ

Satellite Frequency Control
by David Barber 30 Apr '08

30 Apr '08

Perhaps this is a really stupid question? The deviation from the intended frequency of operation of a satellite is often mentioned here therefore would it not be possible to lock the frequency of the payload to a GPS derived source? I appreciate this may not be practical on Cubesats but for longer life products? Comments...

Jules Verne boosts ISS orbit
by uschndr＠zedat.fu-berlin.de 30 Apr '08

30 Apr '08

>From ESA Portal http://www.esa.int/esaCP/index.html 73, Udo,DL7OL ===================================================== ATV demonstrated its ability to raise orbit of ISS Jules Verne boosts ISS orbit 25 April 2008 ESA's Jules Verne ATV was used for the first time early this morning to raise the orbit of the International Space Station. A 740-second burn of the Automated Transfer Vehicle's main engines successfully lifted the altitude of the 280-tonne Station by around 4.5 km to a height of 342 km above the Earth's surface. After the ATV Control Centre (ATV-CC) in Toulouse, France, had 'woken up' Jules Verne ATV, the manoeuvre started at 06:22 CEST (04:22 GMT) this morning and provided a 2.65 m/s thrust using two of the ATV's four main engines. Controllers at ATV-CC closely monitored ATV's subsystems throughout the long manoeuvre. "The Station's altitude naturally decreases with atmospheric drag. Until now this has been compensated for by performing a re-boost using the Russian Progress, the Space Shuttle or by the ISS itself," explains Alberto Novelli, ESAs Mission Director at ATV-CC. "Today, ATV has successfully demonstrated that it too is able to perform this vital function. Only Progress and ATV can provide this high level of re-boost. ATV is unique due to the quantity of fuel available for such manoeuvres." The re-boost manoeuvre comes just three weeks after Jules Verne ATV successfully docked with ISS on 3 April 2008 delivering 1150 kg of dry cargo, including food, clothes and equipment, as well as additional supplies of water, oxygen and fuel. Since then, the European ISS resupply spacecraft has been in dormant mode attached to the docking port on the Russian Zvezda module. Today's re-boost sets up the International Space Station for the arrival of Space Shuttle Discovery on the STS-124 mission to deliver the Japanese Kibo laboratory. STS-124 is currently targeted for launch on 31 May 2008. Further re-boost manoeuvres using ATV are scheduled for 12 June, 8 July and 6 August. Jules Verne ATV is scheduled to remain docked to the International Space Station until early August. At the end of its mission, Jules Verne, loaded with up to 6.5 tonnes of material no longer required by the ISS, will undock and then burn up completely during a guided and controlled re-entry high over the Pacific Ocean.

Delphi c3
by Alan Cresswell 30 Apr '08

30 Apr '08

Hi Once again nothing heard from Delphi over NZ on the 2041UT 36deg fully sunlit pass. Good signals from SEEDS, CUTE1.7 and even chirpy COMPASS. I note that stations reporting no signal today are all reporting on descending node passes while good signal reports are once again reporting on ascending node passes. Unless Delphi is turning off Southbound best guess would be an antenna squint effect. Are any stations reporting reception on Southbound passes? Alan ZL2BX

SEEDS and Delfi-C3 over West Malaysia
by Sion Chow Q. C. (9W2QC) 30 Apr '08

30 Apr '08

Dear All, Had another 57 degree pass of SEEDS and Delfi-C3 over West Malaysia at 1055 hours local or 0255 hours UTC. Again, I was tracking object C, but SEEDS was heard for about 2 minutes more after LOS. This time, unfortunately nothing was heard from Delfi-C3 on 145.870 MHz +/- and 145.930 MHz +/-. SEEDS was very strong though, with occasional QSB. Attempted to try to listen to Cute-1.7+APDII, COMPASS-1 and AAUSAT-II but unfortunately did not hear any signals. The MP3 recording of SEEDS will be posted shortly. Equipment used this time were VHF - IC910H, 2x10 H-Yagi, SB-2000 Preamp and UHF - FT-847, 2x15 H-Yagi, SB-7000 Preamp. 73, Sion Chow Q. C., 9W2QC.

Emergency in Cute-1.7
by Hiroki Ashida 30 Apr '08

30 Apr '08

Hello All, I'd like to inform you about the current status of our satellite, Cute-1.7 + APD II. There has been some strange behaviours on Cute that the battery voltage is very low in the FM packet though it is nominal value in the CW frame. The level of the voltage from FM packet indicates that our satellite may be in danger. We've been investigating the problem but informations we have are very small, so I'd like to appeal for your kind cooperation. Our satellite transmits its beacon at 437.275MHz by CW(Morse Code) and the beacon includes the battery voltage. Details are explained in the web-page: http://lss.mes.titech.ac.jp/ssp/cute1.7/cwtelemetry_e.html There's no FM telemetry transmission excpept over Japan but CW information is remakably helpful for us. If you have any questions, please don't hesitate to contact me. Best Regards, Hiroki Cute-1.7 + APD II -- Hiroki Ashida <hiroki(a)lss.mes.titech.ac.jp> Laboratory for Space Systems Department of Mechano-Aerospace Engineering Tokyo Institute of Technology TEL/FAX : +81-3-5734-2644 Room 554, Ishikawadai 1st Bldg, Tokyo Institute of Technology 2-12-1 O-okayama, Meguro-ku, Tokyo, Japan

ao27.org possible schedule error?
by Sam KC2LRC 30 Apr '08

30 Apr '08

When setting up to work AO-27 yesterday I noticed that the schedule on ao27.org indicated it would be turning on later than normal, with the bird up in Canada. I went out to catch the pass a minute before the scheduled on time and found that the bird was already on. It switched to TLM within a minute and then turned off. Today I went out for the 2022 pass before my tracking program's indicated AOS. The bird was on as it rose and it stayed on for a good 6-7 mins before going to TLM. When I got back in after it turned off, ao27.org listed analog as the current mode, with over 5 minutes remaining. From what I see, the schedule on ao27.org seems to be 8-10 mins off from actual time. The bird doesn't seem to have changed schedule at all. Can anyone else confirm this? 73, Sam KC2LRC Syracuse, NY - FN13

Delfi-c3 heard, packets printed!
by Mark L. Hammond 29 Apr '08

29 Apr '08

Finally got some packets tonight. 30April2008 0225 UTC from FM05pj, 145.930 MHz, LOUD when it came into the sunlight (S7). RASCAL recorded just shy of 100 packets. RASCAL is a neat piece of software! I also copied packets via the DSP-93/TNC in KISS mode. 73, Mark L. Hammond [N8MH]

Delfi-C3 over West Malaysia
by Sion Chow Q. C. (9W2QC) 29 Apr '08

29 Apr '08

Dear All, Finally managed to copy Delfi-C3 during a 9 degree elevation pass this morning, 0922 local or 0122 UTC over West Malaysia. Unfortunately, I failed to log into the Delfi server for some reasons - have to check my login again. Also briefly heard SEEDS again on this pass, while Cute-1.7 + APDII was not heard. Is Cute-1.7+APDII continuously transmitting CW telemetry on 437.275 MHz? Captured telemetry are as below. A screenshot of RASCAL is available at http://www.9w2qc.net/amsatbb/delfi30apr0922.jpg from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 63 06 af 06 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 63 06 b0 06 96 84 eb ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ff 3f fb fb 57 77 00 01 01 09 00 00 00 00 3c 00 a0 83 4c 00 a8 0b 80 09 00 58 0d 40 5f 00 28 07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 63 06 b3 06 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 63 06 b6 06 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 63 06 bb 06 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 63 06 bc 06 96 84 eb ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ff 3f fb fa 57 63 08 00 01 08 00 00 00 00 3d 00 a0 43 4c 00 a0 0b 80 12 00 84 0d c0 6d 00 78 07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 63 06 bf 06 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 63 06 c0 06 96 84 eb ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ff 3f fa fa 58 6a 22 07 00 08 00 00 00 00 3d 00 a0 03 4c 00 38 09 40 12 00 6c 0d c0 63 00 60 07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Tuning the downlink for Doppler is indeed not a simple process but luckily still manageable. Have another pass at 1055 local or 0255 UTC where I will attempt to copy again. Both SEEDS and Delfi-C3 were copied using Object C keps. Equipment used, IC-910H, 2x10 Yagi for VHF, 2x15 Yagi for UHF, SB-2000 VHF Preamp and SB-7000 UHF Preamp. All horizontally polarized. WAV or MP3 recording of Delfi-C3 also available on request. 73, Sion Chow Q. C., 9W2QC.

Delfi-C3
by Alan Cresswell 29 Apr '08

29 Apr '08

It seems that most reports of good Delfi reception relate to northbound passes. So far it appears that Delfi has not been heard in VK/ZL during a number of Southbound sunlit passes despite a number of stations listening and good reception of SEEDS and Cute1.7. Could this be a spacecraft orientation issue or has Delfi just a bit anti Southern hemisphere? Alan ZL2BX

Delfi still not heard over VK
by David 29 Apr '08

29 Apr '08

Hello All, 23:50 2008/04/29 UTC pass - nothing heard from Delfi-3C over VK. Admittedly I was concentrating on SEEDS, which I did hear very well. Yesterday I checked my setup was working by listening to VO-52's beacon and all is ok. Isn't this fun. 73 de David VK5DG

DelfiC3 Spin Rate
by Rob Hardenberg PE1ITR 29 Apr '08

29 Apr '08

Hi All, Good DelfiC3 pass here on 2008-04-29 18:20~18:30UTC. Decoded 223 packets with the Rascal software. This time I used automatic doppler correction and tracked object D. I have the impression that DelfiC3 is earlier than object B. As experiment I tried to determine the spinrate of delfic3 and counted the dips in the signal level. Its 12 dips in 1 minute period so the spinrate at the moment must be 12 rpm or some related number (24,6,3.. rpm). See screenshot: http://www.pe1itr.com/satellite/delfic3_pe1itr_29apr2008.jpg 73 Rob PE1ITR http://www.pe1itr.com

Hello All, In the 21:34UTC pass I received 413 packets. Sadly keps are not accurate so I had to search for the strongest signal (I lost sync somethimes).

I may have missed this in the recent posts but what is the name I would look for if downloading keps and data for this site. I updated my Nova and would like to see this on my map. Fred VE3FAL

Received DelfiC3, TLE and RASCAL screenshot.
by Cor 29 Apr '08

29 Apr '08

Hello All, I received DelfiC3 19:57UTC (orbit nr. 25). I think I received DelfiC3 a bit earlier than my trackings software predicted. Signals where good when DelfiC3 was at south, at north signals dissapeared. Here is a photo/screenshot of Rascal: http://pd0rkc.ontwikkel.nl/29April2008DelfiC3_TLE_orbit25_B.jpg Below you see raw telemetry data. Received with Yaesu FT-897 7el. M2 yagi with horizontal polarisation. I only controlled azimuth because I have no elevation rotor yet. 73's Cor PD0RKC Ham Radio In Space: http://pd0rkc.ontwikkel.nl from: DLFIC3 to: TLM a8 98 9b 40 40 40 00 88 98 8c 92 86 66 01 03 f0 5f

DelfiC3 heard 29-April 18:23UTC - 18:29UTC.
by Cor 29 Apr '08

29 Apr '08

Hello All, There was a low elevation pass in range of Holland (29-April-2008). I could hear the BPSK signal direct at AOS. Signals was somethimes a bid weak (which is normal) and somethimes strong. At 18:29UTC signal stopped direct, maybe mission control team knows why. I could not get data visible on RASCAL because it refuce to accept the audio, the RASCAL audio level meter does not respond. I did select my AC93 soundcard in RASCAL but it does not work. When DelfiC3 was LOS, I have checked PSK signals on HF which decoded fine. Who has some tips? 73's Cor PD0RKC Ham Radio In Space: http://iss.ontwikkel.nl

Re: ao27.org possible schedule error?
by Henk, PA3GUO 29 Apr '08

29 Apr '08

Hi ! Same observation here this weekend. The satellite is a few minutes ahead of the website (it changes mode earlier as the website indicates) Henk, PA3GUO ------------------------------------------------ Hi Sam! > From what I see, the schedule on ao27.org seems to be 8-10 mins off > from actual time. The bird doesn't seem to have changed schedule at all. Can anyone else confirm this? Your observation appears to be correct. I have seen this about a month or so after the satellite gets a new schedule uploaded to it. It appears to be a glitch on the web site. AO-27 should be turning on during afternoon passes when it crosses approximately 29 degrees North latitude.

SEEDS over West Malaysia
by Sion Chow Q. C. (9W2QC) 29 Apr '08

29 Apr '08

Dear All, Finally managed to copy some signals from SEEDS this evening (29th April 2008) after missing it this morning. Some CW telemetry decoded by myself are as follows: Time:2248 Hours Local/1448 Hours UTC Max Elevation: 57 degree 064030 ... JQ1YUSEEDSG4001166B7D69FFE008009000008008007A3E945A3BA0010 ... D064030 ... JQ1YUSEEDSG400116AD2D1BFFE ... 58A4FAAD1100000001000100010A8E0 Time: 2115 Hours Local/1315 Hours UTC Max Elevation: 3 degree 2343BD64FFE007009007007008008A02A059F9A511100000001000100010AC3064030 i ... 8007007008A18A1AA0EA67110000000...........00100010AC4064030 ... JQ1YGUSEE...........4001244DAD61FFE008009000000009008A55A58A5EAAD11000000010 001.....064030 JQ1YGUSEEDSG4001248E8D68FFEO.....00900800800796AA6B9629C31100000001000...... ..... Also tried to listen to the other satellites during the first pass but did not manage to hear anything else. Listened briefly for Cute-1.7+APDII on the second pass but did not hear anything. Concentrated on SEEDS as it was very loud and also I was operating from out of the shack via VNC/Teamspeak and did not want to mess things up. For both passes, object C keps were used. Signals were strong with occasional QSB. Equipment used was IC-910H, 2x15 Element vertically polarized yagi with SP-7000 preamp. Due to my poor CW copying skills, I will post a recording of both passes shortly in case I copied some letters wrongly. 73, Sion Chow Q. C., 9W2QC.

Delfi-C3 HEARD over the Delfi-C3 groundstation 08:53 UTC pass - s/c in EMERGENCY mode
by Wouter Jan Ubbels 29 Apr '08

29 Apr '08

Hi all, we just heard Delfi-C3 again over the Delfi-C3 groundstation on the 08:53 pass. Signal was strong, NORAD Object #32786 seemed to fit best, but we are not 100% sure. Judging from the downlink, the spacecraft is in emergency mode. TLE's for object #32786: 1 32786U 08021D 08119.87805543 .00000721 00000-0 10000-3 0 115 2 32786 097.9993 179.9103 0012861 292.3044 067.6803 14.80984919 100 Frequency: 145.930MHz Downlink signal in emergency mode are 2 tones, of 500Hz and 900Hz each, modulated DSB onto the (suppressed) carrier, use USB to receive this signal. These tones themselves are modulated with 100Bd FSK each with raw payload data. If you hear this signal, please record a wav file if possible. If you hear Delfi-C3 please send your reports to missioncontrol(a)delfic3.nl stating AOS, LOS, frequency, signal strength If possible, please record and attach a WAV file Thanks!

Delfi-C3 HEARD again in SCIENCE mode over the Delfi-C3 groundstation 10:30 UTC
by Wouter Jan Ubbels 29 Apr '08

29 Apr '08

All, Delfi-C3 was heard again with solid signals in SCIENCE mode on 145.930MHz BPSK :) over the TU Delft Groundstation. Everything looked nominal again. We seem to have had an issue with our databus, but the next eclipse solved it. Furthermore, we verified the command uplink functionality and were able to talk to the satellite, we even got an on-board database dump upon command. Awesome. pfewwww.... interesting days these indeed Thanks all for listening and submitting telemetry!!! Wouter Jan Ubbels PE4WJ

Delfi question
by Stargate 29 Apr '08

29 Apr '08

Hi all, I use Orbitron for satellite tracking and get my TLE/KEPS from CelesTrak and/or Space-Track. Whenever there is a new launch, I can never figure out which satellites are "NEW" from the names given on my list of satellites. Does Celestrak/Spacetrak update their data as soon as the bird is launched our should I do it manually? Orbitron has a TLE-NEW.txt file that usually shows the space shuttle launches in a format that I know. (example...STS-123) I hope this makes sense to someone. I'm not sure if I have made myself clear. hihi TIA RoD KD0XX

Re: Delfi_C3 life
by Luc Leblanc 29 Apr '08

29 Apr '08

Hi In a chat session yesterday about DELFI C 3 with Jean-Pierre VE2AHD we are questioning ourselves about the mission length. As per the mission web site (see below) even if the satellite should stay in space for "several decade" the mission lifetime is planned for +- 1 year. As no batteries are in the satellite what will prevent the mission to go where no man has gone before... oups! to go well over the expected one year period? Components failure? this will most likely be the main reason for a limited time frame life expectation? As a cute girl cannot give what she don't have i think there is nothing who will prevent DELFI C3 to live for several years aside of a component failure or a shut down command given from earth. She seems to be made strong but it is an external evaluation... > > How long will the Delfi-C3 be in orbit? > The drawback of the altitude at which the satellite will fly is the decay of the orbit. Due to atmospheric drag the satellite will lose energy, and thus altitude. > For Delfi-C3 this means that it will stay in orbit for several decades. The Delfi-C3 mission has been developed around a mission lifetime of one year. > Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE

Re: Delphi c3
by Alan Cresswell 29 Apr '08

29 Apr '08

Hi David, Yes we can rule out antenna squint because the second pass this morning (2217 UT) was very strong horizon to horizon. Nothing heard on the previous pass and VK's report nothing on the next pass so something seems to be turning Delphi off before it gets down this way. Unfortunately all ascending node passes (Today 9:45pm local and 11:22pm local) are all well into eclipse so we only see a couple of descending node passes in the mornings here. Having only heard the one pass it seemed to be in what the control team described as "emergency mode". I had good sync lock but no packets and it certainly sounded much different from the Demo file which decodes perfectly. I guess we just keep monitoring and waiting down under! 73 Alan ZL2BX -----Original Message----- From: g0mrf(a)aol.com [mailto:[email protected]] Sent: Wednesday, 30 April 2008 01:14 To: alancresswell(a)xtra.co.nz Subject: Re: [amsat-bb] Delphi c3 Hi Alan. I think you're right. Even the teams own news pages say that they have trouble in the morning asending passes, while the evening passes here in Europe are all fine. Possibly a squint problem, but my feeling is that it could be the software latching up after half a pass or so. I note that the evening passes here are all just after exiting eclipse and hence the satellite is 'reset' What are the ascending passes like with you? Thanks David Once again nothing heard from Delphi over NZ on the 2041UT 36deg fully sunlit pass. Good signals from SEEDS, CUTE1.7 and even chirpy COMPASS. I note that stations reporting no signal today are all reporting on descending node passes while good signal reports are once again reporting on ascending node passes.

Delfi-c3 heard!
by Mark L. Hammond 28 Apr '08

28 Apr '08

Okay, finally was in the shack and heard Delfi-c3 come out of eclipse tonight-- 4/29/08 around 02:08 +/- UTC from FM05PJ. There wasn't much of the footprint in the sun, but it was transmitting. No data decoded--by the time I tuned back from its "sister craft" at 437.475/.485 (which I heard some CW) to the 2M side I had missed the strongest signals. In any event, it was unmistakably Delfi-c3 on 145.930 +/- transmitting 1200 BPSK :) Nice job, Delfi-c3 team! 73, Mark L. Hammond [N8MH]

Signals not heard in Northern CA on this pass (on .930 or .870) which should have been much better than the least pass (less trees that way at my QTH). The next pass should be right over Delft and then to my West. Will try then. Maybe they're giving it a rest?? Regards...Bill - N6GHz

Delfi C-3 tracking an keplerian elements
by Jens Kirsten 28 Apr '08

28 Apr '08

Hi Dave, for satellite tracking I use "orbitron". It's easy to use and freeware. You can find it here: http://www.stoff.pl/ The Keplerian elements needed for tracking can be found on the Delfi C-3 web page: http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&Itemid=1… Simply copy and paste the 2-line format in a txt-file and save this file as *.txt. This txt-file can then be loaded into the satellite tracking program, for example "orbitron". Don't worry about Az/El rotor. I could receive almost every cubesat on VHF with my general groundplane antenna. Even with my HT TH-F7E reception in the field is possible. You can also download the RASCAL telemetry decoding software from the Delfi C-3 page. See here: http://www.delfic3.nl/index.php?option=com_content&task=view&id=94&Itemid=1… Best 73! from JO40ja Jens - DL2FJK D.

Hello All, First of all congratulations to the Delfi-C3 team!!! Today I have monitored 3 passes, and the last pass was at 21:13utc - 21:26utc which gave good loud signals. I could not get the data decoded cause I made a mistake with my interface connected on my soundcard. I recorded the pass and here you can hear a short moment (which I have cut out). http://pd0rkc.ontwikkel.nl/28April2008_Delfi_1low2.mp3 73's Cor PD0RKC Ham Radio In Space: http://iss.ontwikkel.nl

Delfi-C3 heard on pass 2115UTC over TU Delft Groundstation
by Wouter Jan Ubbels 28 Apr '08

28 Apr '08

Hi all, we heard Delfi-C3 again on the 2115 pass over the groundstation and heard the spacecraft boot during the pass when she got out of eclipse. Actually, PA3WEG and I are sitting at home controlling the GS via VNC/Skype... worked fine:) Strong sigs again. We can confirm the earlier reports by G0MRF and G8ATE of the sudden dropout of the TX at 145.930. We have observed this on previous passes, usually, the TX comes up on again after a few secs but not so this time. But the "free reset" we got when getting out of the eclipse that followed got it running ok again. We are receiving quite some telemetry on our server, thanks a lot to all of you listening!!! Time to go to bed now:), more updates tomorrow. 73 Wouter Jan Ubbels PE4WJ

Hi. Received good signals from DelfiC3 tonight in IO91TK 15km west of London. Nice to hear another satellite on 2m. Just love that low path loss! 145.930 IC706 + 10m RG58 to roof mounted vertical. No pre-amp. Signals 18dB above noise. Nominal distance to satellite 1400km The signal abruptly disappeared at 19:45 and 5 seconds. ( Command from ground station?)
