SB SAT @ AMSAT $ANS-007.01 PHASE 3D/AO-40 UPDATE AMSAT NEWS SERVICE BULLETIN 007.01 FROM AMSAT HQ SILVER SPRING, MD, JANUARY 07, 2001 TO ALL RADIO AMATEURS BID: $ANS-007.01 AMSAT-DL Vice President Peter Guelzow, DB2OS, provided ANS with the latest information about AMSAT OSCAR 40: Dear All, I know that many people are looking for more information and I can understand this, but please keep in mind that the recovery efforts are not easy and take a lot of time. Everyone involved in the recovery is indeed very busy and we all have our full time jobs and our families to consider in addition to the recovery efforts. Due to the currently limited downlink capabilities, uploading of new commands and analyzing the results takes some time. So far, it has been determined that the L-band uplink receiver (on a high-gain antenna) is OK. Also, the VHF and UHF uplink receivers are OK and they seem to be working nominally. Since we know that the high-gain antennas are working, the V-band transmitter was switched 'on' for 1 MA count recently during a perigee pass over Australia (by command-station Graham Ratcliff, VK5AGR). Telemetry indicated a temperature rise but Graham could not detect any AO-40 telemetry signal on 2-meters. Unfortunately, the telemetry Gram was receiving on S-band at the time of this test was not error free and therefore some telemetry might be missing. The V-TX clearly needs to be tested again in the next few orbits. Magnetorquing did commence and the results will be analyzed. Because of this action some additional FM wobbling may be noted on the S-band downlink when the magnetorquers are in action. If successful, the Magnetorquing attitude control system will allow us to spin 'down' the spacecraft and adjust the attitude for a better sun and squint angle. Following this, it will take some time to evaluate the status of the various other systems and experiments, including the Arcjet and momentum wheels. However, there is a sign of a small leak, which we believe is also the reason for the higher spin rate we are seeing. The internal pressures of the propellant tanks are measured by discrete pressure transducers which are part of the PFA module. While the transducers could be damaged, it seems to be very unlikely. So for now the reason for the leak and the possible effects are under investigation and results will be reported when a final conclusion is made. At the moment we clearly have priorities and the most important one is to bring AO-40 back into 'normal' mode as soon as possible. Depending on the outcome of these tests we can devise a new schedule that best exploits our currently known communications capability. 73, Peter, DB2OS Following Peter's report, AMSAT-DL President Karl Meinzer, DJ4ZC, provided the following: Greetings, Since my report from late December, command stations have implemented the strategy which I had outlined. The first priority was to determine which command-uplink channels were available. This work was difficult, very time consuming (and for the satellite) somewhat dangerous due to the unknowns. The command stations did a magnificent job! Due to their combined efforts I can report the following findings: 1. After some blind transmissions to test the omni-antennas around apogee (that failed to produce a response), the scheduler was activated and programmed in such a way as to prevent lock-out. This strategy turned out to be very prudent and the scheduler-operation went smoothly and resulted in no additional anomalies. 2. The scheduler then took AO-40 through a number of modes, which allowed the P3D team to determine the following: a. V, U and L-1 receivers work b. V, U and L high-gain antennas work c. U and L low-gain antennas do not work d. the status of the V-band low-gain antenna has not been finally determined. Apogee blinds tests are in progress as I write this to accurately determine the status of this antenna 3. As Peter noted the V-band transmitter was operated for one MA-unit. It demonstrated a marked temperature increase, but no signal was heard. This was a quick-look test and this result should not be considered final. Further tests will be necessary (including the need to determine if the matrix was set properly). These tests will have to wait until the spin rate is reduced to ensure that the satellites heat-pipes will be able to handle the dissipation for extended periods. 4. Magnetorquing was started to reduce spin and the first indications are a loss of around 0.5 rpm - roughly consistent with theoretical predictions. We can conclude that the system works. In order to use Earth-sensing data, a small additional program needs to be installed which stores data at apogee for later recovery when telemetry reception becomes available. What's next? During the next days the attitude control system should be returned to full functionality. It will be used to reduce the spin to a value consistent with heat-pipe operation and also with the requirements to change attitude. These changes are necessary for sun-angle constraints, communication access and also to reduce the effect of our ongoing mass-loss on perigee altitude. Newer model calculations show that the mass loss could be larger than my previous estimates; thus it would be prudent to use the resulting thrust to increase perigee altitude (right now it is decreasing it). Once the spin/attitude situation is under control, we will continue the check-out of other systems (such as): 1. Determine the status of the V-band transmitter (controlled experiments) 2. Determine the status of the U-band transmitter 3. Determine the serviceability of the ATOS (Arcjet) to determine if it can be planned on for a strategy toward an improved orbit 4. Test the momentum wheels to determine if AO-40 can be put into a three-axis mode which would greatly reduce the impact of the loss of the omni-antennas Present data so far indicates that although we have lost some systems in AO-40, there has been no further deterioration after the second incident. In particular, if ATOS and three-axis stabilization are still serviceable, AO-40 will still be able to produce a large fraction of the Amateur Radio service expected from it. Personally, I am optimistic and I believe that the command-and engineering team stand a good chance of turning AO-40 into an extremely useful Amateur Radio satellite. 73, Dr. Karl Meinzer, DJ4ZC AO-40 command-station operator Stacey Mills, W4SM, has done a long-term calculation of AO-40's current orbit in the unlikely event that a malfunction within AO-40's propulsion system means that no further orbital maneuvers could take place. W4SM calculates the current orbit will be stable for a very long period. Both the W4SM orbit calculation and the measured AO-40 beacon frequencies (during RF testing in Kourou) have been posted to the AMSAT-DL web site.

Students interviewed station commander William Shepherd, KD5GSL, last Friday. During the afternoon contact about 10 students posed questions to Shepherd, who identified using the special NA1SS call sign. The League reported that the students seemed fascinated with the effects of launch and space flight. Being launched from Earth into space felt like "someone standing on your chest," Shepherd told the students, but after about eight minutes or so "you become weightless and can go anywhere you want." Shepherd told the students that being weightless was "a very nice experience." He also told the Armstrong students that keeping food down in a zero-gravity environment was not a problem. Students at Jan Sheldon Elementary School in Varysburg, New York, are next in line and hope to complete their ARISS contact in mid-January. ARISS is made up of delegates from major national Amateur Radio organizations, including AMSAT. More information about the project can be found on the ARISS web site at http://ariss.gsfc.nasa.gov.

Data recovery at 38k4 is reported to be extremely good with efficiencies near 100%. The output power is at 8-watts "which should provide a very good downlink," said Chris, adding "the downside is that with the high power transmitter operating, the power budget is negative so we can't support continuous operation." According to G7UPN, TiungSat-1 now requires the Amateur Radio station to switch the downlink 'on' when the satellite comes into range. The way this works is for the ground station software to send a request to the spacecraft to switch the downlink on. The spacecraft receives this request and checks the battery voltage to see if it can support the operation, and if it can it will activate the downlink. TiungSat-1 is Malaysia's first micro-satellite and in addition to commercial land and weather imaging payloads offers FM and FSK Amateur Radio communication. TiungSat-1, named after the mynah bird of Malaysia, was developed as a collaborative effort between the Malaysian government and Surrey Satellite Technology Ltd.

This is required to allow control stations to recondition the battery with minimum power drain. I am trying to get this moving as quickly as possible however with the holiday season it may take slightly longer than normal. ProcMail V2.00G has been released by G7UPN. This software permits the processing of image files from TO-31. It has been posted to the AMSAT-NA FTP site at the following URL: http://www.amsat.org/amsat/software/win32/wisp Many of the high-resolution color images transmitted by TMSAT are compressed using a UoSAT compression format. This format is supported by the VK5HI CCD display program.

Prior to this switch RS-13 was operational (mode T), but was apparently turned off following the recent RS-12 switch. The latest information on RS-12 and RS-13 can be found on the AC5DK RS-12/13 Satellite Operators page at: http://www.qsl.net/ac5dk/rs1213/rs1213.html [ANS thanks Kevin Manzer, AC5DK, for this information] KITSAT KO-23 Uplink 145.900 MHz FM (9600 baud FSK) Downlink 435.170 MHz FM Broadcast Callsign HLO1-11 BBS HLO1-12 Launched: August 10, 1992 by an Ariane launcher from Kourou, French Guiana Status: Intermittent operation with the downlink transmitter operating at unpredictable intervals Jim, AA7KC, reports that KO-23's downlink transmitter continues in non-operational status. Jim says that KO-23 shows some signs of trying to recover, but no useful data has been downlinked. The duration of this status is unpredictable. No data has been received since October 28, 2000. KyungHee Kim, HL0ENJ, reports (from the KO-23 control team) that part of the problem with non-operation has been the power budget aboard the satellite. "We are not sure when the bird might turn off again due to insufficient power. The capability of the onboard power system has been less and less," said Kim. HL0ENJ also noted that as of October 30, 2000 the onboard computer was reset and a reboot of operational software is now underway.

Last reported, the satellite does transmit a 9600-baud burst every 30 seconds (the GO-32 beacon sends one short telemetry status transmission of 44 bytes) and upon request the complete telemetry buffer. [ANS has no further information] PANSAT PO-34 Uplink/downlink frequencies have never been released Launched: October 30, 1998 by the Shuttle Discovery Status: Unknown The satellite is not currently available for general uplink transmissions. PanSat was developed by the Naval Postgraduate School. At the time of launch, PanSat spread-spectrum digital transponders were promised to be available to Amateur Radio operators along with software to utilize this technology. To date, this has not happened. For more information, visit the official PanSat web site at: http://www.sp.nps.navy.mil/pansat/ PanSat was the featured cover article on the July/August 1999 issue of the AMSAT-NA Journal (the story written by KD6DRA and N7HPR).

SedSat-1 signifies Students for the Exploration and Development of Space (satellite number one). SedSat-1 has downlinked months worth of telemetry data on the performance of its electrical power system parameters. The Nickel Metal Hydride batteries on the spacecraft were experimental and experienced some abuse due to a power negative situation. This information has provided NASA with useful information. With the exception of the imaging system and the use of the transponders, SedSat-1 has been judged a success.
