November 26, 2017 To All RADIO AMATEURS BID: $ANS-330.01 AO-91 Commissioned - Declared Open for Amateur Use! At 06:50 UTC November 23, 2017 @AMSAT Engineering officially commissioned AO-91 (RadFxSat/Fox-1B) Satellite. AMSAT VP of Engineering, Jery Buxton N0JY turned over operation to Mark Hammond N8MH and AMSAT Operations in a QSO on the AO-91 repeater during the pass over the Eastern U.S. N8MH responded and declared AO-91 open for amateur use! [ANS thanks AO-91 Ops Team for the above information] --------------------------------------------------------------------- Fox-1B/AO-91 Facts Name(s): AO-91 Fox-1B (RadFxSat) NASA catalog number: TBD Launch: Not Earlier Than 21 Sept 2017 NASA ElaNa XIV Mission JPSS-1 Delta II, Vandenberg AFB, CA Orbit: LEO (Low Earth Orbit) Inclination: 97.6908 (Assuming it is Object 43016) Eccentricity: 0259769 (Assuming it is Object 43016) Period: Approx. 95 minutes Estimated orbital lifetime: 5+ years Size: 10 x 10 x 10 cm (4 inch cube) Weight: 1.3 kg (~3 pounds) Transmit power: 400 mW (Minimum) Downlink: 145.960 MHz FM voice AFSK digital data up to 9600 bps Uplink: 435.250 MHz FM voice (67.0 Hz CTCSS tone) >From a communications standpoint Fox-1B has two major changes from AO-85. First, it will fly with a more sophisticated power control system which utilizes a Maximum Power Point Tracker to insure optimum charging of the batteries under all illuminations. This will be largely transparent to the typical user but will significantly increase the available battery life. Second, the detection of the 67.0 Hz tone has been enhanced, which will also help accommodate ground stations whose CTCSS tones may be slightly off frequency. The combination will make accessing the satellite easier and also decrease the likelihood of dropouts. Doppler Shift Correction for Fox-1B Correcting for Doppler shift will involve the same techniques as for AO-85, with slightly different frequencies to prevent mutual spacecraft interference: Receive Frequency Transmit Frequency (67.0 Hz Tone) Satellite Position 145.960 MHz 435.240 MHz (Mem #1) AOS 145.960 MHz 435.245 MHz (Mem #2) Approaching 145.960 MHz 435.250 MHz (Mem #3) Passing 145.960 MHz 435.255 MHz (Mem #4) Departing 145.960 MHz 435.260 MHz (Mem #5) LOS Note that the AFC on the receiver may be working hinting that making the above adjustments may not be necessary. AMSAT VP of Engineering Jerry Buxton N0JY states "... in ground testing with Fox-1A. We could be +/- 10 kHz and not even know it (that's how it was tested, one guy programmed the wrong frequency in his HT)." He adds the caveat, "One station on the uplink is not the same situation as real life though." Fox-1B Telemetry Subaudible Telemetry Except for a different downlink frequency, the low speed subaudible telemetry will be the same as for AO-85. It will be supported by the same FoxTelem software released for AO-85. High Speed AFSK telemetry There are no experiments on Fox-1B which will require the use of high speed telemetry.

FUNcube-1 was launched at 07:10 UTC on November 21st 2013 and its first signals were received immediately after deployment over the Indian Ocean by amateurs in South Africa. Since then it has been operating continuously in either its education mode or, with the transponder active, in amateur mode when in eclipse and at weekends. The spacecraft has spent the four years in space orbiting the earth at between 640 and 580 km and has now travelled around the earth more than 20,000 times. That represents a distance travelled of approaching 500 million miles. Up to now, each of the orbits has been spilt approximately 65% in sunlight and 35% in eclipse. This has resulted in the temperatures inside the small spacecraft varying by about 25o C during each orbit. During the recent AMSAT Colloquium, Wouter, PA3WEG, during his presentation about the FUNcube project mentioned that the power available from the solar panels has been slowly increasing since launch. This observation led the team to do some further investigations as to the cause. Although the launch was into a nominally Sun Synchronous orbit, over time this has drifted and the spacecraft is now entering a period when it will be in the sun for longer periods during each orbit. The exact details are still being determined, but it seems likely that, starting from January 2018, there will be periods when the spacecraft will be in the sun for all, or almost all, of its orbits. Of course, this means that the on-board temperatures will be much higher than we have previously experienced in flight, although we have some test records from pre-flight thermal air testing that were undertaken after integration. The key will be to discover what the equilibrium temperature will be internally. For comparison, AO85 has already "enjoyed" periods of full sun and its internal temperatures have reached up to around 55o C. So the next few months will be quite an exciting time for the team! We remain extremely grateful to everyone is using the spacecraft for both its educational and amateur missions. Of course we are also very very grateful to those who are downloading the telemetry and uploading the data to the Data Warehouse. It continues to provide a unique record of "life on board" a 1U CubeSat in space. FUNcube-1 / AO-73 details TLM down link freq 145.935 MHz BPSK Transponder: Nominal Uplink 435.150 - 435.130 MHz LSB (Inverting) The passband may be up to 15kHz higher depending on on-board temps. Low temperature gives higher freqs! Downlink 145.950 - 145.970 MHz USB Please use a maximium uplink power of 5 watts to a 7 dBi gain antenna. More power is not needed to use the transponder! Currently operating full power TLM beacon (300 mW) when in sunlight, and Transponder, plus low power (30mW) TLM beacon when in eclipse. Normally switches to Transponder over weekends and holidays [ANS thanks Funcube.org for the above information] --------------------------------------------------------------------- Video of Launches of the Currently Orbiting FUNcube Satellites Wouter Weggelar, PA3WEG, released a composite video showing all currently orbiting FUNcube family satellites being launched: https://www.youtube.com/watch?v=hLevT3C5v6c&feature=youtu.be [ANS thanks Wouter PA3WEG and AMSAT-UK for the above information] --------------------------------------------------------------------- EcAMSat Deployed From ISS - 1200 baud Telemetry & QSL Card for Reports The E. coli AntiMicrobial Satellite (EcAMSat) mission will investigate space microgravity effects on the antibiotic resistance of E. coli, a bacterial pathogen responsible for urinary tract infection in humans and animals. EcAMSat is being developed through a partnership between NASA’s Ames Research Center and the Stanford University School of Medicine. Dr. A.C. Matin is the Stanford University Principal Investigator. EcAMSAT was deployed from the ISS on November 20, 2017. EcAMSat will investigate spaceflight effects on bacterial antibiotic resistance and its genetic basis. Bacterial antibiotic resistance may pose a danger to astronauts in microgravity, where the immune response is weakened. Scientists believe that the results of this experiment could help design effective countermeasures to protect astronauts’ health during long-duration human space missions. Operating at 437.100 MHz FM, the EcAMSat beacon sends an AX.25 packet every 5 seconds, similar to the format of the GeneSat-1, PharmaSat, O/OREOS, and SporeSat beacons; the packet contains data about the spacecraft systems operation. A tracking screen, mission information, and mission status are dis- played on the EcAMSat Mission Dashboard: http://ecamsat.engr.scu.edu/ Links to beacon decoding and packet uploading instructions are also included on the Dashboard. An example of the EcAMSat QSL card is displayed at: https://yc3bvg.blogspot.com/2017/11/ecamsat-qsl-cards.html [ANS thanks the EcAMSat Team and NASA for the above information] --------------------------------------------------------------------- MAI-75 SSTV Over Moscow from ISS Planned for December 6-8 The MAI-75 folks have scheduled some SSTV activity during specific periods each day from Dec 6-8. The times correlate to a small number of passes each day in range of Moscow. Dec 6, 2017 Setup and power on - 13:40-14:20 UTC Power off - 17:05-17:15 UTC Dec 7, 2017 Power on - 13:45-13:55 UTC Power off - 17:30-17:40 UTC Dec 8, 2017 Power on - 14:05-14:15 UTC Power off and stow - 17:00-17:10 UTC See: https://ariss-sstv.blogspot.com/ [ANS thanks ARISS for the above information] --------------------------------------------------------------------- UT1FG/MM Now Active Yuri, UT1FG/MM, is back to sea on the Vessel Seahorse. It is currently sailing from Algiers to Morocco where it will load cargo. The plan is to sail to a USA port in the Gulf to be determined. There are quite a few ships named Seahorse. The MMSI number is 538007572. Yuri is using the Elk antenna but only has RG58 coax feeding it. Even so he reports working K3SZH on AO-7 today. If he doesn't find coax in Morocco, perhaps we can get some coax to him when he arrives in a USA port. So he is likely to do better on a Mode B satellite rather than one with a UHF downlink. He has keps for AO-91, AO-85 and CAS-4B. Please wait for a while before sending your logsheets. He will likely be able to mail qsl's when he docks in the USA.

Next week we will continue with the normal TLE distribution on each Thursday of the week. Note that, per comments below, AO-91 is most likely object 43016. It appears that AO-91 is in the group of cubesats launched on 11-18- 17 that include objects 43016, 43017, and 43018. The object 43015 that we were using for AO-91 has separated enough to be confirmed as Buccaneer RRM by 18th Space Control Squadron at Vandenburg AFB, CA. One of 18 SPCS many missions is launch analysis. Therefore, based analysis (by Nico Janssen, (PA0DLO) and discussion by Alan Biddle (WA4SCA), Jerry Buxton (N0JY), Nico Janssen (PA0DLO), Paul Stoetzer (N8HM) and myself AO-91 is most likely object 43016. Note that these objects are still very close together and one more change could be needed. The process of identification is one of waiting for a group of objects to separate enough to isolate the one you are interested in and positively identify it's signal as matching a certain TLE set. Simple, right! For comparison, Buccaneer (object 43015, not AO-91) is now at least 26 seconds from objects 43016, 43017, and 43018. Objects 43016, 43017, and 43018 are still about 2 seconds apart.

N2YO tracking of AO-91
by Kevin M 25 Nov '17

25 Nov '17

After observing discrepancies between tracking on the N2YO website and actual observation, I asked some questions and figured out that there may be some initial confusion lingering over which object is which. I'm told that catalog ID 43016 is most accurate and after checking, it does agree with my observations. So for anyone that has N2YO bookmarked to track AO-91, here is the link to what I believe is the correct tracking: http://www.n2yo.com/?s=43016 I know N2YO has things labelled differently, but I have sent him a message to check on it. Just wanted to let folks know in case they are also having similar problems. N2YO is a great resource, in my opinion, and I've been using it for tracking the birds going on 5 years now. My thanks to N2YO! 73, Kevin N4UFO

HRD inverted satellite problem
by Ted 24 Nov '17

24 Nov '17

Hi Michael, I discussed this topic several months ago, on email, with Mike Carper, the owner of the HRD program. Mike told me he was committed to 'fixing' that portion of the program. I just forwarded your post to him and asked him to weigh in on this bbs. In the meantime, tell the person you talked to that the HRD Sat portion simply DOES NOT WORK, especially on linear birds. It will get by on most FM birds, at least in the past. (it got me my VUCC mostly on AO-51) If you intend to get back to the person at HRD, tell them the best illustration of the problem in THEIR software can be shown by picking any satellite pass: start up HRD's sat program side by side with SatPC32 (you really don't even need a radio connection). Then look at the numbers for alt, elv distance, etc. They will not even be close. Since we know SatPC32 is the current 'gold standard', we can conclude that something in HRD is not right or not calculating properly. Simple as that. HRD cannot keep blaming someone else. The sat portion simply does not work. I hope Mike joins this bbs and stands by his commitment, as expressed to me, to fix his great software, which clearly has the best graphics of any sat program in the marketplace. 73, Ted K7TRK -----Original Message----- From: AMSAT-BB [mailto:[email protected]] On Behalf Of mvivona--- via AMSAT-BB Sent: Friday, November 24, 2017 11:43 AM To: amsat-bb(a)amsat.org Subject: Re: [amsat-bb] HRD inverted satellite problem Hi All, HRD (Ham Radio Deluxe) has just sent me an email wanting me to buy the latest license for ver-6. I replied to them that I would love to if they have fixed the know long standing issue with Doppler control of inverting satellites. I received a prompt reply with the typical "never heard if this" attitude without actually saying it. He wants to know what my station setup is. Radio, Windows version, connection, etc. I wonder if one of you fine gentlemen can give a knowledgeable description of the exact circumstance and issues.It has been several years since I tried and failed with HRD and I don't actually remember the particular circumstances, and, so I don't have to go all through loading everything back on my computer and working through all the scenarios to find the problem. thanks in advance.

AO91 on LOTW
by John Geiger 24 Nov '17

24 Nov '17

Made my first AO91 QSOs today. Sounds like an excellent satellite! Congrats to all involved for the successful launch and activation. I worked Gabe AL6D (congrats on new call) for a new grid. However, on TQSL you cannot choose AO91 for the satellite used. Has anyone heard from the ARRL as to when AO91 will be added? 73 John AF5CC

AO-91: *No* uplink frequency changes needed for Doppler shift
by John Klingelhoeffer 24 Nov '17

24 Nov '17

I am puzzled why I am seeing announcements going out from apparently several sources indicating user UHF uplinks need to be changed to adjust for Doppler shift near to their own AOS and LOS. I'm seeing this posted from the AMSAT-UK website as well as other places. The FOX1-B UHF receiver has automatic frequency control (AFC) that will slew the uplink users signal to the middle of the IF filter and the discriminator if s/he is anywhere within about +/- 10 kHz of the nominal uplink frequency. From what I remember, the worst case UHF Doppler shift was about +/- 8.5 kHz. There should be *NO* need at all to 'predistort' the uplink transmission frequency to correct for uplink Doppler shift - that was the whole purpose of going through the complexity of adding AFC to the receiver I designed. The AFC was certainly working fine during testing. Just use the posted nominal uplink center frequency - that's all. This, by the way, is true for 1-A as well. Only one of 1-Cliff or 1-D has the AFC knowingly disabled. I guess we will see how that 'experiment' works when they get out of the barn. 73 John... WB4LNM AMSAT FOX RF Design Team

AO73 and EO79 Operations
by Graham Shirville 24 Nov '17

24 Nov '17

Hi all, Just to confirm that AO73 is now in full time transponder mode for the weekend. Also please note that EO79 is presently not operational - more news soon. 73 Graham G3VZV ++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from PM Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, e.g. Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 – 435.130 MHz LSB (Inverting) Downlink: 145.950 – 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15 kHz higher depending on on-board temps. Lower temperatures give higher freqs!) FUNcube-2 (aka FUNcube on UKube) The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 – 435.060 MHz LSB (Inverting) Downlink: 145.930 – 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 ** EO79 is presently not operational - further information will be made available as soon as possible** Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula… EO88/Nayif-1/FUNcube-5 EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, i.e. the solar panels are NOT being illuminated. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. The transponder frequencies are: Uplink: 435.045 – 435.015 MHz LSB (inverting) Downlink: 145.960-145.990 MHz USB Telemetry Tx: 145.940MHz All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very grateful for the assistance given by Innovative Solution In Space Bv, The Netherlands.
