SB SAT @ AMSAT $ANS-051.01 STENSAT RELEASED AMSAT NEWS SERVICE BULLETIN 051.01 FROM AMSAT HQ SILVER SPRING, MD, FEBRUARY 20, 2000 TO ALL RADIO AMATEURS BID: $ANS-051.01 StenSat has been released by the OPAL 'mother ship' but the ARRL is reporting that little or nothing has been heard from the Amateur Radio picosat, raising fears that it has malfunctioned. StenSat was one of two picosats released February 10th by OPAL -- Stanford University's Orbiting Picosat Automatic Launcher. The other was the JAK payload. Since the deployment, stations monitoring StenSat's 436.625 MHz downlink have heard only very weak signals, or nothing at all. According to Hank, N4AFL, StenSat may be operating in an "abnormal mode." The picosat was supposed to transmit a CW identifier and packet telemetry after deployment, but neither have been heard. N4AFL is speculating that the satellite might be operating in FM transponder mode, telling ANS that "during testing of StenSat we made some late changes to the audio mixer that feeds the AX.25 and CW telemetry from the controller unit to the transmitter." N4AFL thinks it may be possible that this circuit has failed and that no telemetry is being transmitted and an un-modulated carrier is being transmitted instead. To test this theory N4AFL is requesting that stations try to place StenSat into voice transponder mode by issuing a DTMF command and then transmitting a modulated uplink signal. The DTMF command for placing StenSat into transponder (repeater) mode is: #6676326 Cliff, K7RR, reported hearing his transmissions repeated through the satellite recently, but signals were weak and the audio distorted. The StenSat group is asking amateurs to continue monitoring the downlink and send any reports (via e-mail) to: hheidt@erols.com More information is available on the StenSat Web site at: http://users.erols.com/hheidt/ [ANS thanks the ARRL and Hank Heidt, N4AFL, for this information] /EX SB SAT @ AMSAT $ANS-051.02 ISS UPDATE AMSAT NEWS SERVICE BULLETIN 051.02 FROM AMSAT HQ SILVER SPRING, MD, FEBRUARY 20, 2000 TO ALL RADIO AMATEURS BID: $ANS-051.02 The International Space Station continues to operate in good working order - now in its fifteenth month in orbit. Flight controllers continue to manage electrical power through the batteries inside the Zarya module, recharging four of the six on-board power plants. Battery 1, which has experienced some problems, will be replaced by Shuttle astronauts later this year on the next mission to ISS. Space Shuttle and ISS managers discussed the option of flying a maintenance mission to the Station prior to the upcoming launch of the Zvezda module. At the request of the ISS program, shuttle managers approved an option of scheduling the next shuttle mission to the ISS Station no earlier than April 13, 2000 (prior to the Zvezda launch), to perform maintenance tasks on the Zarya and Unity modules. The Kurs automatic docking system was tested twice recently without problems in an effort to verify that the system is ready to support the rendezvous with the Zvezda service module this summer. The Kurs system is the Russian automatic docking system located inside Zarya used to rendezvous with the service module for precise docking. NASA managers also approved Shuttle mission STS-106 as the flight which will follow the launch of the service module. Seven crewmembers will spend a week docked to the ISS, loading supplies in the new Zvezda module and activating some of its systems. The International Space Station is in an orbit of 240 by 226 statute miles. Since the launch of Zarya in 1998, the ISS has completed more than 7,105 orbits.

Despite a problem with a small nitrogen thruster on the end of the 200-foot-long mast, both the C-band and X-band radar continue to perform as expected, and the thruster problem has had no impact on mapping operations. Processing of the huge amount of data gathered by Endeavour -enough to fill about 13,500 CDs if all goes according to plan- will result in maps 30 times more accurate than the best global data available now. The maps also will be of unprecedented uniformity as Endeavour gathers mapping data at the rate of 40,000 square miles of land each minute. Endeavour's crew and flight controllers continue troubleshooting a small problem with a nitrogen thruster mounted at the tip of the radar's outboard antenna. Although gaseous nitrogen propellant is flowing, little or no thrust is being produced. Without the thruster on the antenna, crewmembers have to fire the orbiter's thrusters more than expected. Mission Control also told the astronauts that the EarthKAM aboard Endeavour has successfully transmitted over 2,000 images for middle school students across the U.S. EarthKAM, mounted in the overhead starboard window of Endeavour's aft flight deck, lets middle school students take pictures of the Earth. They use interactive web pages to select photos. As this edition of ANS was being prepared, Endeavour continued to function well.

SunSat has been in mode-B (FM) using an uplink of 436.291 MHz (+/- doppler) and a 145.825 MHz downlink. SunSat was launched February 23, 1999 aboard a Delta II rocket from Vandenberg Air Force Base in California. SunSat stands for Stellenbosch University Satellite and takes it name from the South African university whose students constructed the payload. The SunSat package includes 1200 and 9600 baud digital store-and-forward capability and a voice 'parrot' repeater system that will be used primarily for educational demonstrations. The satellite has two VHF and two UHF transmit-receive systems.

Chris Jackson, G7UPN, reports to ANS that UO-22 has now entered full sunlight and the temperatures have increased considerably. Controllers have turned the satellite upside down to point the critical systems to cold space. This has reduced the temperature on various systems (such as the batteries) by between 5 and 10 degrees. The unfortunate by-product of this is that the downlink is now quite weak. The satellite will remain in full sunlight until late March, when controllers will turn it back 'over' again. According to G7UPN "over the next few years this situation will become worse as the no eclipse periods become longer." Only the 145.900 MHz receiver is usable for communications at the moment.

The battery voltage during daylight passes has dropped slightly. The average value observed was 13.8 volts, with a range of 13.6 to 14.1 volts. The internal temperatures have decreased slightly. They are now 5.0C and 3.2C for battery and telemetry electronics respectively. A WOD survey dated (January 6th) has been transmitted. The mode-S beacon is on and transmitting an unmodulated carrier. The beacon is a useful test source for testing mode-S converters prior to the launch of P3-D.
