SB SAT @ AMSAT $ANS-168.01 ISS OPERATIONS CONTINUE AMSAT NEWS SERVICE BULLETIN 168.01 FROM AMSAT HQ SILVER SPRING, MD, JUNE 17, 2001 TO ALL RADIO AMATEURS BID: $ANS-168.01 Students at the Henley Middle School in Klamath Falls, Oregon, enjoyed a voice contact with astronaut Susan Helms, KC7NHZ, aboard ISS recently. Using the NA1SS call sign, Helms answered a dozen questions from the students (several of whom are licensed amateurs) during the voice exchange. Many of the youngsters who listened to the contact also belong to the Klamath County Schools Amateur Radio Club, KC7VWW. In addition to the school QSO, several stations have informed ANS of random contacts with the International Space Station. The Henley Middle School contact was handled via the telebridge-equipped station of AMSAT member Tony Hutchison, VK5ZAI, in South Australia. The Expedition-2 crew of Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms have now completed over 100 days in space since they were launched on March 8th. Currently, the crew is performing a complete checkout of the station's robotic arm (Canadarm2). In addition, Yury Usachev and Jim Voss performed their first spacewalk around the ISS recently, completing all of their scheduled tasks smoothly and ahead of schedule. The two spacewalkers entered the small, spherical transfer compartment at the forward end of the Zvezda Service Module to begin the first spacewalk at the ISS without the presence of a shuttle. The International Space Station is currently orbiting the Earth at an altitude of around 240 miles.

OSCAR-11 was launched in March 1984 by a Delta-Thor rocket from Vandenberg Air Force Base in California. Clive, G3CWV, reported to ANS that it has been an uneventful time for OSCAR-11 during the period of May 15-June 9, 2001, with good signals received from the 145.825 MHz FM (1200-baud AFSK) downlink and the mode-S beacon transmitting on 2401.500 MHz. Battery voltage observed during daylight passes has continued to decrease. The average value observed was 13.3 volts with a range of 13.1 to 13.5 volts. The internal temperatures have continued to decrease, now -0.2 and -1.6 Celsius for battery and telemetry electronics respectively. The magnetometer calibrations have steadily changed during the many years in orbit. Although the changes are small and are not noticeable on a plot of individual channels, they do have a considerable effect when the total magnetic field is calculated. The spin period has also varied, now between 300 and 344 seconds, with the attitude control working normally. As noted above, the mode-S beacon is active, transmitting an unmodulated carrier. This beacon is a useful source for those testing mode-S converters for receiving AO-40.

Status: Operational, mode J. Periodically, AO-27's analog repeater will be turned off for a few days at a time to enable ground controllers to gather Whole Orbital Data (WOD), to verify the health of the satellite. 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. TEPR states on AO-27 were reset on March 24, 2001 as follows: TEPR 4 is 38 / TEPR 5 is 78 (TEPR 5 is now 20 minutes long) The AO-27 pages on the AMSAT-NA web site include an explanation of TEPR AO-27 operations (at): http://www.amsat.org/amsat/sats/n7hpr/ao27.html [ANS thanks AMRAD for AO-27 information] UO-14 Uplink 145.975 MHz FM Downlink 435.070 MHz FM Launched: January 22, 1990 by an Ariane launcher from Kourou, French Guiana.

Status: Operational at 38k4-baud FSK Several stations report they have not copied the satellite since early May over North America. Chris, G7UPN, tells ANS that 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.

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 was 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 frequency (listed on the PanSat web site) 436.500 MHz Launched: October 30, 1998 by the Shuttle Discovery Status: Unknown The satellite is not available for general uplink transmissions. The Naval Postgraduate School developed PanSat. 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] DOVE DO-17 Downlink 145.825 MHz FM (1200-baud AFSK) 2401.220 MHz Launched: January 22, 1990 by an Ariane launcher from Kourou, French Guiana. 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. [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 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.
