SB SAT @ AMSAT $ANS-035.01 PHASE 3D/AO-40 UPDATE AMSAT NEWS SERVICE BULLETIN 035.01 FROM AMSAT HQ SILVER SPRING, MD, FEBRUARY 04, 2001 TO ALL RADIO AMATEURS BID: $ANS-035.01 The month of February begins with command stations continuing their on-going recovery efforts of AMSAT OSCAR 40. The AMSAT-DL web site is currently featuring the following statement: AO-40 is currently like a ship on a sandbank at low-tide and in the fog. In the fog because of the high solar-angle (maximum of 77 degrees) where the onboard sun sensor(s) temporarily cannot see. At low-tide because the increasing solar-angle leads to less illumination (minimum of 23 percent) - thus less energy is produced. AO-40 is stuck on a sandbank because the satellite cannot be maneuvered out of this situation very easily. The 'de-spinning' software routine may help. This program should work without sun sensor data and will use on-going measurements from the solar panels as an attitude indicator. Intensive work on this software is currently taking place. Even if this routine doesn't work immediately, there is no reason to panic. The 'fog and low-tide' orbit will disappear with further seasonal Sun movements around the spacecraft. By April the sensors will see the Sun again and active attitude control can be restarted. After lowering the current spin rate, improving the Sun angle and repositioning AO-40's antennas, all further tests can be done. Command stations G3RUH and W4SM have completed a long-term prediction of AO-40's new orbit. Even after last year's accident and the resulting decrease of perigee - AO-40's orbit will be fairly stable through this period. ALON/ALAT is currently 248/-7, as last listed on the AMSAT-DL web page. The AO-40 element set (number 30) is as follows: Satellite: AO-40 Catalog number: 26609 Epoch time: 01027.28372779 Inclination: 5.8370 degrees RA of node: 227.6036 degrees Eccentricity: 0.8132970 Arg of perigee: 212.6216 degrees Mean anomaly: 48.4646 degrees Mean motion: 1.26933309 rev/day Decay rate: -7.0e-07 rev/day^2 Epoch rev: 111 Checksum: 274 Stay tuned to AMSAT News Service, the official source of AO-40 news and information.

Johann, ZR1CBC, first broke the unfortunate news on the AMSAT-NA bulletin board: "Our last contact with SunSat was on January 19, 2001 at 15:22:37 UTC. Unfortunately, little hope remains after two weeks of recovery attempts. My thanks to all who shared in our fun, your feedback and continual encouragement made most of it happen. I hope to talk to you on AMSAT Oscar 40 soon." 73, ZR1CBC Houston, Texas AMSAT Area Coordinator Bruce Paige, KK5DO, recorded the very first operational pass of SunSat over the North America - it's available at the following URL: http://www.amsatnet.com/so35.ram The SunSat team released the following statement, dated February 1, 2001: We regret to announce that the last communication with SunSat from our ground station at the Electronic Systems Laboratory at Stellenbosch University took place recently. We are certain, after having performed several tests since the last contact, that an irreversible, physical failure has occurred on the satellite. It is therefore unlikely that we will have any further contact with SunSat, apart from the occasional visual sighting by telescope! The SunSat team reported that SO-35 was recently exposed to continuous sunlight for a period of five months due to orbital parameters. The orbit was determined by the requirements of the Danish Orsted satellite, on which the SunSat platform was based. SunSat was a secondary (and free) payload attached to the Orsted spaceframe. When the satellite became exposed to the full sun period, the SunSat command team continuously re-oriented the satellite in an attempt to alleviate high operating temperatures and battery overcharging. The ground team realized that battery capacity was a problem and efforts to recondition the battery cells seemed to help at first, however, the satellite then suddenly failed. Interestingly, the ground team does not believe battery failure was the cause of the shutdown. The team believes the failure resulted from multiple internal problems or a possible collision with an external object resulting in major physical damage. The SunSat web site did not contain any information as to if the Orsted platform also suffered an operational failure. The SunSat team was (nevertheless) very satisfied with SunSat's achievements in orbit during the period of nearly 2-years since launch. Built by graduate students at Stellenbosch, SO-35 was launched on February 23, 1999, from Vandenberg Air Force Base in California aboard a Delta II rocket. When it was operational the SunSat package included 1200 and 9600 baud digital store-and-forward capability, a voice 'parrot' repeater system and Mode B/J operation with two VHF and two UHF transmit-receive systems. ANS would like to congratulate the SunSat team for their outstanding achievements with SO-35 and thanks all the Amateur Radio operators that were associated with the satellite.

During this time MGS was able to globally map the planet while monitoring seasonal changes. Some channels visible on the surface of the planet may have been gouged by ice, rather than by catastrophic flooding, as is generally believed. -SpaceDaily ** Meeting in Irving, Texas recently, the ARRL Board of Directors voted to increase membership dues from $34 to $39 annually for full members younger than 65, and from $28 to $34 for full members 65 and older. The dues hike goes into effect July 1, 2001. The last ARRL dues increase was in July 1997. -ARRL Letter ** Software developed by the Aerospace Corporation can save satellites from failure, extend the on-orbit life of satellites with ailing hardware gyros and save large sums of money in insurance costs, among other benefits. More information is available at the following URL: http://www.spacedaily.com/news/space-salvage-01a.html. -SpaceDaily ** NASA reports its NEAR Shoemaker space probe is set to drop to its final resting place on the asteroid Eros shortly, sending pictures as it goes. The robotic spacecraft, which left Earth five years ago and spent the last year orbiting the asteroid and taking pictures, is scheduled for a controlled descent to the surface of Eros two days before Valentine's Day. It is scheduled to land gently at the edge of a saddle-shaped feature called Himeros. -Roy, K6DUE ** AMSAT-NA is please to report we have met our first $1,000 challenge (a dollar match for new and lapsed memberships). It's now time for the second challenge. Through the month of February all donations (up to $1,000) will be matched. Let's show support of AMSAT and the outstanding jobs done by our volunteers! -ANS ** Students at George West Elementary School enjoyed the latest successful ISS school contact. Students asked several questions related to microgravity and even the dreams the crew might have as they sleep in space. A crowd of about 75 teachers and relatives joined the many students as the contact took place. The contact was 'rock solid' with very good signals reported throughout the 10-minute pass. -ARISS/ARRL --ANS BULLETIN END--- /EX SB SAT @ AMSAT $ANS-035.05 WEEKLY SATELLITE REPORT PART 1 AMSAT NEWS SERVICE BULLETIN 035.05 FROM AMSAT HQ SILVER SPRING, MD, FEBRUARY 04, 2001 TO ALL RADIO AMATEURS BID: $ANS-035.05 Phase 3D / AMSAT OSCAR 40 / AO-40 Launched: November 16, 2000 aboard an Ariane 5 launcher from Kourou, French Guiana.

Status: Operational at 38k4 baud FSK Chris, G7UPN, tells ANS that recently TiungSat-1 has been operating at a data rate of 38k4. 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.

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. [ANS thanks Jim Weisenberger, AA7KC, and KyungHee Kim, HL0ENJ, for KO-23 status information] TECHSAT-1B GO-32 Downlink 435.225 MHz using HDLC telemetry Launched: July 10, 1998 by a Russian Zenit rocket from the Baikonur Cosmodrome. Status: Semi-operational. Efforts were reported to be underway to bring GO-32 on line, however, no information has been received by ANS (the last report was dated November 1999). 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). [ANS has no further information] MIR SPACE STATION 145.985 MHz (FM) voice and SSTV (Robot 36 Mode) Launched: February 18, 1986 Status: Unmanned Currently, there is no human habitation aboard the station and the onboard Amateur Radio equipment has been turned off. Several news agencies are reporting the Mir space station will be ditched in a controlled descent that will send it hurtling into a remote area of the Pacific Ocean in early March 2001. MIR SAFEX II 70-cm Repeater Uplink 435.750 MHz FM w/subaudible tone of 141.3 Hz Downlink 437.950 MHz FM Status: Not operational.

Status: Non-operational. DOVE has been in orbit for 11 years. DOVE stopped transmitting in March 1998. The 145.825 MHz and 2401.220 MHz downlinks are off the air and the satellite has not responded to ground station control. [ANS has no further information] WEBERSAT WO-18 Downlink 437.104 MHz SSB (1200 baud PSK AX.25) Launched: January 22, 1990 by an Ariane launcher from Kourou, French Guiana. Status: Non-operational. WO-18 has been in orbit for 11 years. WO-18 was last reported to be in MBL mode after a software crash. [ANS has no further information] SEDSAT-1 SO-33 Downlink 437.910 MHz FM (9600 baud FSK) Launched: October 24, 1998 by a Delta 2 rocket from Cape Canaveral, Florida. Status: Semi-operational. The satellite is not currently available for uplink transmissions and the image and transponder recovery efforts have been unsuccessful. 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.
