SB SAT @ AMSAT $ANS-226.01 ARIANE 5 AGAIN CLEARED FOR FLIGHT AMSAT NEWS SERVICE BULLETIN 226.01 FROM AMSAT HQ SILVER SPRING, MD, AUGUST 13, 2000 TO ALL RADIO AMATEURS BID: $ANS-226.01 Arianespace's Flight 130 is back on track following a launcher hardware change-out decision to ensure the highest level of reliability for the upcoming Ariane 5 mission. Two thruster modules consisting of three thrusters each are integrated into the vehicle equipment bay of the Ariane 5 launch vehicle. The replacement of six thrusters in the Ariane 5's attitude control system for Flight 130 was decided after another thruster failed during a test-bench firing in Europe. The firing was a long-duration test for the future "Versatile" version of Ariane 5's EPS upper stage. An investigation revealed a problem in the brazing of two pieces inside the failed thruster, which resulted in Arianespace's postponement of Flight 130 from the original July 25 launch date. "Our position is clear: we simply do not launch if there is any question about hardware or system reliability," Jacques Rossignol, Arianespace Executive Vice President, said. "When the thruster problem occurred in Europe, we wanted to make absolutely sure that we resolved all questions about the flight hardware on the Flight 130 launch vehicle in French Guiana." Arianespace worked closely with Astrium, the attitude control system supplier, in investigating the thruster failure and developing a recovery plan for Flight 130. Together, it was decided to replace all six thrusters on the Flight 130 launcher's attitude control system -- selecting other thrusters after subjecting them to ultrasonic inspection. The replacement thrusters will be test fired, and will be shipped to French Guiana for installation on the Ariane 5. "We had excellent cooperation with Astrium throughout the entire process, which once again demonstrates the benefit of long-term relationships that have been established by Arianespace with its industrial team," Rossignol said. The attitude control system for Ariane 5 is incorporated in launcher's vehicle equipment bay, and consists of two thruster modules with three thrusters each. The hydrazine propellant-fed system ensures roll control during the flight of Ariane 5's main cryogenic stage and its upper stage, as well as providing three-axis control during all satellite positioning maneuvers. Flight 130 will carry the dual payload of the SES Astra 2B and GE Americom GE-7 satellites. The mission's new launch date is set for September 14.

An AO-27 question-and-answer page is available on the AMSAT-NA web site. The URL is: http://www.amsat.org/amsat/intro/ao27faq.html. AO-27 uses a method called Timed Eclipse Power Regulation (TEPR) to regulate the on-board batteries. In simple terms, TEPR times how long the satellite has been in an eclipse (or in the sun) and decides what subsystems to turn on or off.

Chris Jackson, G7UPN, reported to ANS last March that UO-22 was in full sunlight and the temperatures had increased considerably. Controllers (at that time) turned the satellite upside down to point the critical systems to cold space. At the time of the last report only the 145.900 MHz receiver was usable for communications. No further information has been received from the UO-22 ground control stations on the status of UO-22.

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). The TechSat-1B micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998. Last reported, the satellite does transmit a 9600-baud burst every 30 seconds (for a continuous 3 seconds in length) on 435.225 MHz. The TechSat team has a home page about TechSat.

The satellite is not currently available for general uplink transmissions. PanSat, developed by the Naval Postgraduate School, was launched from the shuttle Discovery (during STS-95) on October 29, 1998. 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.

AMSAT's Bruce Paige, KK5DO, reported that cosmonauts Sergei Zalyotin and Alexandr Kaleri arrived on the Russian Mir space station after an April 4, 2000 launch from the Baikonur Cosmodrome and the successful docking with Mir. After just over two months in space the cosmonauts returned to Earth in June. During their stay the ham radio equipment aboard Mir was activated in a very limited fashion. Currently, there is no human habitation aboard the station and the onboard Amateur Radio equipment has been turned off. Several news agencies have reported that Mir in now on 'autopilot'. Stay tuned to ANS for further details. 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.

No operation in 1999 or 2000 has been observed. DOVE DO-17 Downlink 145.825 MHz FM (1200 baud AFSK) 2401.220 MHz Status: Non-operational. 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. No additional information is available at this time. WEBERSAT WO-18 Downlink 437.104 MHz SSB (1200 baud PSK AX.25) Status: Non-operational. WO-18 was last reported to be in MBL mode after a software crash. No additional information is available at this time. SEDSAT-1 SO-33 Downlink 437.910 MHz FM (9600 baud FSK) Status: Non-operational. The satellite is not currently available for uplink transmissions and the image and transponder recovery efforts have been unsuccessful. SedSat-1, signifying Students for the Exploration and Development of Space (satellite number one) was successfully launched and placed in orbit on Saturday, October 24, 1998. 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.
