More on the transponder.
by Rsoifer＠aol.com 05 Aug '11

05 Aug '11

Further to my last email, a full quarter-wavelength antenna for 435 MHz would be about 6.5 inches long. Lou estimates that the actual antenna is only about 1.5 inches. The short length has two effects: a reduced capture area for reception, and a greater likelihood of blockage by the main body of the spacecraft. If it's blocked, it won't hear much of anything. If it isn't, it looks like it will hear the bigger AO-13/AO-40 class stations (typical EIRP about 1 kW). With my EIRP of 50 watts, I tried CW instead of SSB. I heard myself for about 2 minutes, but was only 449. We'll see if anyone else can hear me in the next few days. 73 Ray W2RS

TLM Rx 1579utc
by Edward R. Cole 05 Aug '11

05 Aug '11

My system received 5 frames of Telemetry and 2 Frames of Kursk - while I was sleeping! Yeah, I set the radio to 145.920 and had the telemetry program running, and went to bed after the 1111utc pass over Alaska. That was only a 1-degree elevation pass and I saw no signal. I overslept this morning (again) and woke up eight minutes after the last pass LOS, but there on my screen was the data and a message from my anti-virus sw asking if I wanted to connect to the telemetry site. I approved that so hopefully the frames made it. MY station is pretty simple: Home made "AA2TX" Lindenblad antenna with 80-feet of RG-213 coax to a DEMI L144-28 transverter (NF=1 dB) with Elecraft K3 IF radio connected to my computer via HB soundcard interconnect. Note there is no preamp but the transverter has good NF. ARISSat was at 6-degrees elevation when the data was received. I am using NOVA with keps: RADIOSCAF-B 1 37772U 98067CK 11216.75158638 .00033717 00000-0 40433-3 0 12 2 37772 051.6382 276.2984 0012892 043.5724 316.6246 15.60501122 76 Next pass visible to Alaska will be 10:14utc 8-6-2011 I will set up for the linear transponder to test ability to pass signal on a later pass. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-100w, 1296-60w, 3400-?

Hi Amsat, Arissat1.org, My name is Gert (ON3SWY) and I was able to receive the ARISSat1 2m FM downlink signal this morning CET. It goes without saying that I am very interested in receiving your PDF certificate. I received the FM signal with an honest 59. The secret word copied from my end was "Eagle". Full name: Gert Verswyvel. Date/Time of reception: Aug 5 2011 05:38 AM CET (03:38 UTC) E-mail address for certificate: on3swy(a)on4hrt.org Receiving a signal from an orbiting object for the very first time was quite an experience. Thanks in advance. Kind regards, Gert, ON3SWY

KB5WIA Update - CM79+
by David Palmer KB5WIA 05 Aug '11

05 Aug '11

Hi Everyone, Here's an update on the CM79/CM89/CN70/CN80 plans. CM79 is not an easy grid to work from. Aside from being physically remote, and being a strenuous hike (800' climbing) from the nearest road, the actual topography of the grid is difficult for radio operations. The actual grid corner is in the middle of a thick manzanita and poison-oak forest, 70 feet down the western slope of a steep ridge. In other words, from anywhere you are in CM79, there's a steep hillside blocking the radio path to the east! The best location is actually the convergence of the four grids at the northeast tip of CM79, where it's close enough to the ridge top that a remote antenna can be used to get the signal over the ridge. The problem then becomes how to have the station itself on the grid convergence (down the hill) and still be able to get signals "out". Following discussion with (and approval from!) ARRL HQ, here's the plan for operation from CM79: Station Setup for Overhead and Westerly satellite passes: Full station set up directly over grid square intersection. Specifically, I'll use the standard setup that I have used before, consisting of two Yaesu FT-817ND radios hanging from a photographic tripod, with the 6.4Ah LiFeP04 battery right next to the tripod. The antenna is an Elk antenna on top of the tripod. The area of the grid intersection will be marked with a ground tarp, and will be determined with better than 20' accuracy with WAAS-GPS. Photo and video will be used to document the station, GPS receiver, and surroundings. Station Setup for Easterly satellite passes: Since the view to the east is blocked by a ridge, 70' uphill, for easterly passes I will use the exact same station as above, except that the Elk antenna will be relocated to a second photographic tripod perched on the ridge. The Elk will be connected via 100 feet of LMR-400 coax, and I will use a preamp at the antenna to help overcome the signal loss on the 70cm downlink. As above, all station operation will be from directly over the grid intersection, including tuning, transceivers, and power source. The Elk can be re-aimed once or twice through the satellite pass to more or less keep up with the sat as it moves. What this means: 1) Lower signals. Expect my signal to be weaker than it is during my normal portable operations (ie Death Valley, etc). Since overhead and westerly passes will have tree cover, and the easterly passes will have to use the 100-foot coax, my uplink signal to the birds won't be as strong as it has been. 2) Fading on eastern passes. Anyone who has operated portable knows a big advantage of handheld ops, that helps overcome the reduced gain of the smaller antennas, is that you can rotate the antenna to exactly match the current polarization of the satellite. By necessity, I'll lose this advantage on easterly passes with the remote antenna, since there's no way I can be both at the operating location (to hear the return signals) and the antenna (to flip it back and forth). So, expect my signal to fade in and out as the polarity changes. 3) Time lag to hear sat on my RX end. Since I'll be using a 100' run of LMR400 to carry both the uplink AND downlink signals for the eastern passes, this necessarily means that the antenna-mounted preamp is going to switch off during transmit. The SP432VDG takes about 1-2 seconds to come back "on-line" after I unkey, so on V/U birds if you come back to me immediately I may not hear you. Rapid exchanges on eastern passes probably won't work for this reason, I'll have to take it slow. 4) I'll be going QRT mid-pass once or twice to re-aim the antenna. The Elk antenna has a fairly wide beamwidth, but certianly not enough to cover a whole pass. On eastern passes, I'll have to leave my operating position and hike up to the ridge to point the antenna, then will have to get back down to the operating location. I won't have to do this on overhead or western passes. 5) For specific birds: AO-51 if active: This one has good strong signals. Should be OK for both eastern passes with the remote antenna and western passes with the normal configuration. My 1-2 second time lag on RX might be problematic if the sat is congested. SO-50: This one's pretty weak to begin with. I'll be lucky if I can hear anything even with the preamp on the remote antenna, so don't expect too much on eastern passes. Hopefully will be OK on overhead or western passes. AO-27: Probably the same as AO-51. FO-29: Normal for overhead and western passes. For eastern passes, my preamp will cut out during transmit with the remote antenna, so I'm pretty sure I won't be able to find my uplink. I'll therefore be effectively running half-duplex. If you hear my call, come back to me slowly, so I can use your downlink to zero my tuning. AO-07: Normal for overhead and western passes. I'll likely have a very weak uplink on the eastern passes using the remote antenna to get over the hilltop -- input power to the Elk will only be around 2 watts. Listen carefully and have patience. VO-52: This one actually works pretty well with the remote antenna setup! Expect some fading, but this one should be okay. My website has the most recent information, and you can check the SPOT tracker on my QRZ page to see if I'm at the location or not. Hope to work many of you on the trip! 73 de Dave KB5WIA http://kb5wia.blogspot.com

Hello Last night KP4WK and myself (KP4TR) listened to Arissat when overhead in Puerto Rico last night. In our case we both live in Florida and was out of reach at that time, but we each own a remotely operated stations at our parents home. This gives us the advantage of listening and maybe working arissat when outside our reach over the Atlantic. My remote radio in San Juan has a computer with SSTV capability so on the weekend ill try to capture some images as it flies over puerto rico. Sent from my Adobe Flash and Java challenged iPhone

Today's Success
by Edward R. Cole 05 Aug '11

05 Aug '11

I'll try to keep this short...."Whose Success?" If I were still a member of Amsat, I would be very upset with the handling of this project. There is nothing for the contributions that ham radio members invested. It ends up only glory for ARISS and the Russian's commemoration of Yuri Gagarin. I would vote to cut the relationship between Amsat and ARISS. It isn't offering anything for ham radio. Let ARISS raise their own funds and build their own educational satellites. Those that want to contribute to that, go ahead. Amsat was created to build satellites capable of ham radio communications (and be used by hams)...this education outreach was added, much later. But then I quit Amsat after 36-years. You know what? Keep this up and it could become a trend. Ed - KL7UW former #3212 PS: They were right about my proposal: It would fail. Now you have the evidence.

No - We didn't have our new ham satellite to work that night. But to call Yuri's Night a "failure" is quite wrong - as would attendees of more than 550 parties in 75 countries across seven continents will tell you.

I spent the last two days building and putting up a temporary NVIS antenna for 60 meters that I needed for a R.A.C.E.S. exercise that took place yesterday. I used insulated wire, hose clamps, two telescoping pool cleaning poles, 4 random sections of TV antenna mast, some PVC pipe, some wood, hose clamps, and cable ties. I whacked the poles into things while moving them, scraped some doors, smashed a finger, left cut cable ties all over the yard, twisted the wires, pulled down one end support trying to put up the other, lost cable ties, and slightly bent a small bit of my backyard fence. If I had been on TV while doing this and I had to undergo the same scrutiny given the ARISSat launch by some in this crowd, I would no doubt be considered to be the clumsiest person on earth with no idea what I was doing and no clue how to do it. But you would not have been there in the 108 degree heat, to appreciate the amount of effort necessary to get this done by one person in a short period of time, with limited resources. And the antenna worked well, and accomplished its mission. So has ARISSat. If you didn't put it together and you didn't launch it... don't tell those who did, how they should have done it. Thank you. It's good to see those here who are focusing their energy on the rewards and celebrating the success, rather than complaining about the perceived mishandling (a.k.a. backseat driving). I watched the launch while we were doing our exercise, and I can't wait to get my opportunity to hear and work ARISSat this weekend when I'm not stuck at work!!! Until then, jealously enjoying reading your reports. 73 Jerry N0JY

a little perspective
by Bruce Robertson 04 Aug '11

04 Aug '11

I wonder if I might hope that the outrage from us amchair cosmonauts will abate by tomorrow. Let's take a look at what we need and what we've got: as an organization, we need cheap rides to space; but we have some pretty find satellite-building expertise. The relationship with ISS will, if we are reasonable, give us cheap rides. The NASA-TV announcer repeatedly said that ARISSAT-1 was the prototype of a series of satellites! Already, we've had the opportunity to fly our first SDX.The cost of making more along the lines of ARISSAT-1 is minimal compared to the cost of the ride, so this is a crucial relationship. What does ISS want from our relationship? Probably, an increased sense of purpose: we get a ride, they get recognition, and perhaps a bit more TV time for the EVA, and a connection with student research. Here's where it counts for us to be polite in a difficult situation. Focusing on errors, nationalistic name-calling, and the rest, just diminish what they get out the bargain, and make things more difficult for those who work with us who have negotiated these waters. Besides, I think the criticisms underestimate the technical difficulty and novelty of what we've been part of. I've watched many EVAs, and the feeling that things are not exactly going by plan is pretty common (even when Americans are running the show :-) How do you most reliably ship and store a small satellite to an orbiting space station? How do you most safely jettison it during EVA? As a species we have very little experience with this, and didn't get it 100% this time. Surely, kudos is due to AMSAT for being part of the group that is trying to answer these questions. Anyway, I have more fun thinking of it that way. And I'm looking forward to downloading as much telemetry for Kursk as I can. 73, Bruce VE9QRP -- http://ve9qrp.blogspot.com

And now for something different

All, Got this from one of my astronomy buddies, thought it might be of interest to some on this list. Would've posted it sooner but it got lost among all the chatter about ARISSat-1: Just announced, a huge nearly x class solar flare that was earth directed should yield some aurora possibly here in Arizona: Moving at an estimated speed of 1950 km/s, this CME is expected to sweep up two earlier CMEs already en route. Analysts at the GSFC Space Weather Lab say the combined cloud should reach Earth on August 5th at 13:55 UT plus or minus 7 hours: "The impact on Earth is likely to be major. The estimated maximum geomagnetic activity index level Kp is 7 (Kp ranges from 0 - 9).

Congrats on ARISSAT-1 deployment and Telemetry
by charlie Cantrill 04 Aug '11

04 Aug '11

Congrats to AMSAT on a job well done! My cisco networking class participated in receiving SSTV images, telemetry, and they got a kick out of the voice greetings. The Decoder was a snap once I found the CW spike in the spectrum and got it lined up. We did notice the deep fades and can see the fades in the SSTV images, and one student pointed out the panel voltages and temps confirming the rotating. Looks like the z- panel was spending more of its time out of the sun. Charlie CantrillKI4RDTNelson County Area Technology Center

Russia Today reports Kedr deployment
by andy thomas 04 Aug '11

04 Aug '11

Guys you won't like it - brace yourself: BEGINS New satellite to commemorate first space flight permalink email story to a friend print version Published: 03 August, 2011, 20:02 Two Russian cosmonauts have left the International Space Station for a six-hour spacewalk to mark the 50th anniversary of the first-ever manned space flight by Yuri Gagarin with the launch of the unique microsatellite. The cosmonauts will spend about six hours outside the ISS and for the first time ever computerized Orlan-MK spacesuits with liquid crystal displays will give advice and instructions in case of emergency situations, such as increased oxygen consumption. During the spacewalk, the cosmonauts will launch a microsatellite made entirely by Russian university students. The satellite – which is dubbed “Kedr” (cedar) after Yuri Gagarin’s call sign – will be broadcasting greeting messages from outer space in 50 different languages to mark the 50th anniversary of the first-ever manned space flight. The cosmonauts will also install laser communication equipment on the outside of the Russian segment of the ISS. However, it does not mean high-speed internet will be available in the Russian segment, as long as “the new optical equipment is intended primarily to transfer science video to enhance the efficiency of the scientific activity of the cosmonauts,” the head of the extravehicular activity department of RSC Energia, Aleksandr Polishchuk said. With the US Shuttle program shutting down last month, Russia is currently the only nation able to send people to the stars.

Re: [suitsat2] Did Drew Hear Himself?
by Bill Ress 04 Aug '11

Steve - - additional, you may recall the RX tests in the clean room at your place. The RX is very sensitive having a NF (which includes the front end SAW filter) of just under 5 dB. Lou - thanks for commenting on what probably remains at the 70 CM input. I did some rough calcs and with the sensitivity of the RX and about 1.5" for an antenna, sub-microvolt signals will be heard. The 1 watt test Drew ran attests to that. So what this all means is that the transponder function is only minimally impacted by the lack of a 1/4 wavelength antenna. We need to get the word out that most typically equipped 70 CM satellite stations will make it through. Right now most everyone is focused on the easy signals but the linear transponder is almost fully functional. The very sweet thing is that with the transponder functioning we can now verify that the SDX is spot on in every way designed (Nice job guys!!) Another good test will be to exercise the command function. Now it will take a bit more power at the satellite which was by design anyway. I'm sure that's in the plan after the dust settles.

ARISSat-1 What a Ham Radio Achievement!
by Harry Strahlendorf 04 Aug '11

04 Aug '11

Hi Gang, I excitedly tuned my base station, connected to a dual band Ventenna on the roof, to the downlink frequency of 145.950 mHZ this morning as I tracked ISS on a pass over North America. I'm in Southern New Jersey. I was amazed to be able to hear the initial greeting female voice from this special bird! On the following pass I used a portable HT and Arrow Antenna out on the lawn and copied ARISSat-1 5X9! Thanks to all who made this possible and all who are helping us enjoy this wonderful hobby! Sincerely & 73, Harry ~ W3DNQ

Two signal reports
by Philip Jenkins 04 Aug '11

04 Aug '11

145.95.Mhz, 0557 UTC, 45 degree pass here in western NC (still using the Comet quad-band vertical). Lots of fading, but I did catch that voltage was 31.5. I thought that the vertical would do ok at a 45 degree elevation, BUT I found out differently on the next pass I listened to... 145.95 Mhz, 1400 UTC, 13 degree pass to from NW to SW. (Voltage was 34.0; had just come out of eclipse a few minutes before.) I was using the Arrow antenna into the HT, and was listening to the mobile rig with the quad-band vertical at the same time. I thought the vertical would really shine at such a low-angle pass, and while it was ok, the Arrow blew it away. I knew there would be a big difference, but not a HUGE difference. With the Arrow, I heard the satellite long after I thought it would have faded entirely behind the mountain(s). Darn it, now I have to do some research on knife-edge diffraction on 2 meters around mountain tops/ridges <grin> I think I'll try the CW beacon tonight - won't be until approx 0320 UTC before the satellite is back in range, and then it's only a 4 degree pass. (70 degrees on the next one though) Philip N4HF

Feedback on BPSK decoding
by Phil Karn 04 Aug '11

04 Aug '11

I'm interested in people's comments on the reliability of the BPSK-1000 digital link in the presence of the deep periodic fading that everyone is reporting. This fading is probably because the spacecraft hasn't settled down into a stable spin around its preferred spin axis (which includes the antennas). But I designed the BPSK-1000 format to be specifically resistant to fading, so I'm really curious to see how well it's working in practice. Although the decoders don't explicitly distinguish between lost frames and idle link time (hard to do given the signal design) you can gauge the effectiveness of the decoding from the amount of data you do successfully decode per unit time. If people could estimate how many bytes per minute of decoded data they're getting, and assuming the computer doesn't let the link idle very much, that would be a good indication of how well the system is performing overall. The channel symbol rate is 1000 Hz. After rate 1/2 Viterbi FEC the actual link data rate is 500 bps. From this you have to subtract idle inter-frame time and HDLC frame overhead (flags, 4-byte CRCs, etc) that varies with the length of the frame, leaving the data. So in 1 minute you could receive up to 3750 bytes of binary user data. How close are people coming to this figure? Phil

Yes! It is something that should be asked. We know from the so called test and the Yuris Night deal that the bird was used in ways not previously known. So either the antenna broke off or was not attached. This was not the crew that would have deployed in February. As has been said before beggers can't be choosers. If interested people pony up the bucks we can build and pay to launch anything and be autonomous. The reality is that raising several million dollars is not going to happen. So we take what we can get for now and celebrate the good as best we can. ARISSAT from my understanding was always what it is an education sat. The fact it has a transpoonder was a nice add on thanks to SDR and a test for the Fox platform. It was not advertised as an amateur only bird. ---------- Sent via Cricket Mobile Email

I agree not matter what you do unless its absolutely perfect and even when it is someone has something to cry about. I am a small part of the ARISS operations team and fairly new Area Coordinator. I understanf the complaints. I also was leary of calling it ARISSat because ARISS really only gave its name. Locally the failure of Yuris Night did little to promote ARISS quite the contrary. Remember this started as Suit Sat 2 and was or is a Russian experiment as was Suit Sat 1. ARISS has been working the STEM of ham radio long before it was cool.

It's probably in a very obvious place, but I have not found it. Here is a little excerpt from my data from this morning: Column one is obvious (date & time stamp); what are the others? 2011/08/04-12:23:13 84 81 11 0 0 72 105 44 32 84 104 105 115 32 105 115 32 65 By the way, we are very excited about this project at my school.

Stop this damn bickering. Have fun!

04 Aug '11

That is IMHO. We need constructive posts not this one-up-manship crap. Has anyone posted any live WAV files anywhere, so we can experiment with them while waiting for an ARISSat1 pass? I have been able to copy the BPSK telemetry two times. I am using HRD Sat Tracker and the Doppler is not keeping up. I have to manually correct for the errors. I am using the Keps which are on the AMSAT website. I am finding the operating frequency to be much lower then 145.920. But, also, this was with a 70 degree elevation pass which requires quite a bit of Doppler correction. And also it is using USB so I guess if I did the math it would be right on. Whatever...I am having a blast trying to copy it. I even got up twice in the middle of the night to try it. I want to have a much fun as I can before the batteries go dead. That is a whole other topic that may get people bickering. I have the same feeling about the means and methods as many of you, but airing them here is not going to change a damn thing. If you all put as much energy in contacting those idiots in Washington about the mess they are making of our economy, ETC, we might be better off. Again, that is IMHO. 73, *Carl W8KRF *

It is closely following the ISS presently. You should switch to SATPC32 available at the AMSAT website for purchase since this is the program AMSAT supports.. Join AMSAT too!

Thank You to the ARISSat-1 Team
by Joseph Armbruster 04 Aug '11

04 Aug '11

I would like to send a personal Thank You to AMSAT and the ARISSat-1 Team. You overcame an enormous amount of challenges in order to make this happen. I am personally thankful for all of your hard work. From a technical standpoint, you had to manage a design change (suitsat -> arissat), the new design, materials, fabrication, assembly and software. From a scheduling standpoint, you had to deal with volunteer schedules, NASA, the Russian Federal Space Agency and all sorts of other events. From a logistics standpoint, you had to move materials all over the planet so that everyone could do their part. And keep in mind, the volunteers making this happen mostly have full-time jobs, families and many other things to do :-) When I tell non-ham (non-Amsat people) that I know how: """AMSAT built a satellite 'in a garage', had it delivered to the ISS and it's now in orbit sending down pictures, yadda, yadda""", you should see the looks on peoples faces!! I get the goose bumps just thinking about it. It is truly an amazing feat and an outstanding accomplishment for AMSAT. As far as the failures are concerned, I will defer to a magnet that I have on my workbench that says: "Success is going from failure to failure without a loss of enthusiasm". Thank you all for your hard work, Joseph Armbruster

And, if you took my whole snipet, you will see that I gave him the exact information he needed to fix his NOVA problem.

Yes, I have been the recipient of many requests for assistance to get SATPC32 functioning, however, it is never the programs fault-it is 99% of the time - the users inability to get their computer operating- Sounds like a Bill Gates problem to me.

transponder ?
by jerry keeton 04 Aug '11

04 Aug '11

I recall the actual birthplace of ARISsat-1 was SuitSat-2 . I may be mistaken. However after following the progress , I never recall it's intentions of being a SSB Transponder . It seems the two ssb birds that are in orbit and useable do not get near the traffic the FM birds get . There is only one digital sat working which sees a lot of traffic . I enjoy the digital birds much more than listening to rag chew on voice . There is always HF and VHF repeaters for ragchewing . I really would prefer a digipeater on the Lunar surface . And someone could set up a link from the in orbit sats so We could skip from RS0ISS to other satellites . But I applaud the crew that built ARISsat , it would have been one great machine for the entire Ham community. Jerry WB5LHD

Good signals from ARISSat-1 with transistion from eclipse to sunlight here this morning. Apx. 6 second spin period puts deep nulls in transmitted signal. - Not sure if this is due to linear polarisation of my receive antenna or blockage from spacecraft. Managed to capture just 3 tlm frames and '2 Kursk frames' . (mission time 29997-30018) However, software forwarded zero frames via internet (?). If recording to a .wav file, CW positioned to be 500Hz seems to work well. Battery voltage around 33V status - charging. Thanks David G0MRF

Let's redirect our energy
by E. Michael McCardel 04 Aug '11

04 Aug '11

Gould touches on something I haven't heard mentioned here, "...potential for STEM education." STEM = Science, Technology, Engineering, and Mathematics. It is what is driving education and schools are hungry for community involvement from people who can present projects that help the schools meet STEM education standards. (see stemeducationcoalition.org) Perhaps we should address the impact ARISSat-1 should have on education and the potential of introducing what we do to large amount of young minds. Instead bitching about what has gone wrong, should we redirect our collective energies contacting teachers and local school officials and explaining the educational impact of ARRISat-1, the help them setting up an antenna receiver and installing software. Engage the students. Show them what a great hobby we have and follow-up in getting them more involved. We have a golden opportunity that worth more than 100 grid squares contacts via the transponder. Something I consider more valuable than the cost of deploying this thing, Young Minds. We are lacking dreamers in this age. Here is our chance to create some. Hmmm, maybe one of these kids who get involved will be become our best ally when they go to space.

ARISSat-1 in SATPC32
by Alan P. Biddle 04 Aug '11

04 Aug '11

Hi, The deployment of ARRISat-1 is approaching. Here is a collection of data on the various modes for use in configuring SATPC32. Note that you will need to tweak the sideband frequencies slightly to account for rig calibration and other issues, as usual, but these should be close. You can paste these in the DOPPLER.SQF file, but before you do, please read on! ARISSat-1,145918.5,0,USB,,,0,0,BPSK/CW-2 ARISSat-1,145950.0,0,FM,,,0,0,VOICE/SSTV ARISSat-1,145930.0,435750.0,USB,LSB,REV,0,0,XPDR ARISSat-1,145938.5,0,USB,,,0,0,CW-1 Since ARISSat-1 will be deployed by a gentle push from the ISS by Cosmonauts, the ISS Keps will be good until separate Keps are released by Space Track. One way to handle the transition is to change the Doppler information slightly: ISS,145918.5,0,USB,,,0,0,BPSK/CW-2 ISS,145950.0,0,FM,,,0,0,VOICE/SSTV ISS,145930.0,435750.0,USB,LSB,REV,0,0,XPDR ISS,145938.5,0,USB,,,0,0,CW-1 Paste the ARISSat-1 data as desired, and also paste the ISS version of the data into the DOPPLER.SQF file after the regular ISS data. For the final test aboard the ISS, and initially after deployment, select ISS tracking, and then select the desired ARRISat-1 frequency data at the end of the list in the CAT window. After the ISS and ARISSat-1 are far enough apart that independent Keps are available, you can begin using ARISSat-1 as a separate object by adding it to the objects you track in the Satellites menu window. The satellite may be identified as ARISSat-1, but may well have some other designation which will be reported. If it is not ARRISat-1, then change the name in the first group above to that used in the Keps. They must agree exactly for SATPC32 to match the Doppler data with the satellite. (You can also use the AmsatNames.txt file, which is covered in the SATPC32 documentation.) You can then delete the extra ISS data if you wish. They won't hurt anything, but it will clean up the ISS CAT window. 73s, Alan WA4SCA

Hello, Are there keps for this bird yet? So far I’ve been listening using the ISS keps in SATPC32 but eventually this wont work. What will its official designation in the downloadable keps files be? Also, do we have a “final answer” on the UHF side? Is there an antenna or not? Mike WB1AAT

Great pass over Chicago. Strong signals, copied voice telemetry, greetings, SSTV. Following the threads here, it may not be perfect but it's a hell of a lot better than Suit Sat and is proving new systems and technologies. As far as "educational outreach" goes I know that the ham community is a friendly and welcoming place, that's why we reach out. I also know that some members of the satellite ham community are very upset that the dream of HEO and geosync are not reality. You can blame and point the finger at whoever you want, it's a simple fact that it costs money to get there, even as a ride share you are talking about a minimum of $1M so unless you are ready to pony up the bucks to get there.......

I heard the CW beacon at 1217 UTC with a strong (min. S5) but noisy signal.

Hi all, Apologies - I may have caused the confusion in my recent report on hearing the satellite this morning in Wales -UK. I had the ISS on my mind with using it with using it as a source for tracking ARISSat-1 and posted an incorrect frequency. It was of course operating on the correct published frequency. Put it down to "age" or my pleasure of having such success. Sincere Apologies to all. Ken Eaton GW1FKY

ARISSat-1 in Intermittent Mode Over USA
by Richard Crow 04 Aug '11

04 Aug '11

Since ARISSat-1's first three passes over the USA have occurred in darkness, it appears it is in intermittent mode. This is as Gould Smith stated in his post titled "ARISSat-1 Deployed !". That is, "ARISSat-1 will ... go to Low power (intermittent) mode when in eclipse". On the 145.950 MHz FM downlink, intermittent mode appears to mean about 45 seconds ON followed by 120 seconds OFF. Presumably, other signals from ARISSat-1 follow a similar schedule. I'll check this when I get a chance. That being said, ARISSAt-1 was heard loud and clear on all of its first three passes over northeastern USA near Binghamton, NY. Specifically, the 04:20, 05:54, and 07:31 UTC passes. Can't wait until the 09:08, 10:45, and 12:21 UTC passes for my location when ARISSat-1 will enter full sunlight and switch to continuous operation. Richard N2SPI

ONE ARISSAT ANTENNA MISSING, Reports Novosti
by andy thomas 04 Aug '11

04 Aug '11

02:28 04/08/2011MISSION CONTROL, August 4 (RIA Novosti) Related News Two Russian cosmonauts leave ISS for spacewalk ISS crew to launch mini-satellite on August 3 Multimedia Spacewalk Humans in space: results of the past 50 years International Space Station Two Russian cosmonauts, Alexander Samokutyayev and Sergei Volkov, completed their 6-hour spacewalk on Thursday with a 40-minute delay and returned to the Russian segment of the International Space Station (ISS). They carried out a manual launch of a mini-satellite and installed new stream video equipment on the station's outer surface. This was the first spacewalk for Samokutyayev and the third for his colleague Volkov. The launch of the Kedr mini-satellite, designed to transmit greeting messages in 17 languages, Earth photos and telemetry data from its service systems, was delayed after the cosmonauts discovered that one of its two antennas was missing, but they nevertheless launched the satellite with only one antenna. The cosmonauts also installed three containers with microorganisms and mushroom spores on the Pirs docking compartment to study their influence on materials used in spacecraft construction. At the end of their spacewalk, the Russians took pictures holding photos of the first cosmonaut Yury Gagarin, spacecraft designer Sergei Korolyov and Soviet astronautic theory pioneer Konstantin Tsiolkovsky with Earth in the background. http://en.rian.ru/science/20110804/165547335.html 73 de andy g0sfj

THE ROUGH TREATMENT OF ARISSAT-1
by John Marranca, Jr 03 Aug '11

03 Aug '11

I don't quite understand the "high-fiving" going on in regards to "Congrats on the deployment of Arissat-1". Bullshit. Someone's ASS should be on the line for the rough treatment of this "project" (as NASA TV kept referring to it as). As far as I'M concerned...they sent out INEXPERIENCED rookies to deploy something that, while minor in the grand scheme of projects undertaken by ISS/NASA, was still important to US and the university that built the pressure experiment onboard. What if these cosmonauts DID destroy it? What if it had to be brought back to Earth? Who would have paid for it? Or would it have been a loss for the contributors involved? My 2 cents!'

Re: ARISSat-1 - Photos from NASA TV
by Burns Fisher 03 Aug '11

03 Aug '11

Thanks to everyone who posted pictures. I think Phil Karn's picture number 9204 is particularly interesting. It almost looks like something coming out of the collar and bending back and down away from the camera. Any chance that is an antenna stuck somewhere? But I'd also like to make a couple comments which are, of course, just as much speculations as the comments that I'm trying to refute. First, let's talk about "breaking" the antenna. Well, we don't really know that. Isn't it flexible like the 2m antenna? I think it was mentioned in CDR slides. And surely we would want it to be flexible. After all there is one of these sticking out on each of the two largest flat surfaces. Chances are good it's going to run into something sometime. Second, suppose it was simply not installed. I see lots of comments about "duh, how could you miss it not being there?". I've looked at a lot of pictures of this bird both pre- and post-launch and a huge percentage of them are taken at an angle where you can only see one antenna. How would anyone inherently know what this was supposed to look like? I would also add that these guys who are on the station for 6 months at a time don't get to practice procedures in a tank up till a few days before the EVA. As to the Apollo 13 mentality: This was not life or death. The guys inside the station were limited as to where they could go. Surely they could not pass something out through the airlock even if they could move around. And does anyone remember on Apollo 12 (I think), one of the astronauts kicked a TV camera cable so we had no live TV after the first few hours. Should I mention a certain cap not removed from a certain Oscar on the pad at KSC? That was not the Russians. Working in space is HARD. Mistakes are EASY. Here's my completely speculative hypothesis: You'll recall that the AMSAT rep who went to Russia (Lou?) with the bird had to return before it was at Star City because of a combo of a short visa and long customs hold. Thus he never got to work in person with bird AND the Russian guy working up procedures, tests, etc. On top of that, the various tests from within the ISS were added. All that could add up to procedures being written and changed somewhat blindly. I'll bet some checklist somewhere neglected to mention the 70cm, and in the process of stowing and unstowing and connecting to and disconnecting from the external antenna the 70cm was never (re) attached. Yes, I'm disappointed. Yes there should be a root cause analysis. But as before, we have to wait till the details are in. Speculations are fun; throwing blame around is not (to me at least). 73, Burns W2BFJ

0417 UTC pass East Coast
by Philip Jenkins 03 Aug '11

AOS was 0417, LOS 8.5 minutes later...only 13 degrees elevation for me in EM85tm/tn. Didn't hear anything until 0422 and then only for about 1 minute; not sure if it was BPSK or SSTV. Although signal was plenty strong, signal cut out at times, probably due to satellite tumbling. Antenna is the quad-band vertical Comet mounted on the car. The next pass is in about 90 minutes @ 45 degrees elevation. If a 13 deg pass sounded like that, I'm sure the 45 degree one will wake me up! :-) Philip N4HF (near Asheville, NC)
