SB SAT @ AMSAT $ANS-105.01 PHASE 3D / AMSAT OSCAR 40 UPDATE AMSAT NEWS SERVICE BULLETIN 105.01 FROM AMSAT HQ SILVER SPRING, MD, APRIL 15, 2001 TO ALL RADIO AMATEURS BID: $ANS-105.01 April continues with recovery efforts concerning AO-40. The satellite appears to be healthy and reports indicate that very good telemetry has been received recently. AMSAT-DL is reporting that the S-band beacon on AO-40 may not be transmitting continuously during each orbit. The AO-40 team received a report from Gunter, DF4PV, that he was suddenly loosing the signal from the S-2 beacon transmitter. DF4PV reported the signal disappeared during a period where the satellite apparently entered an eclipse. AMSAT-DL responded that the onboard IHU is running a software task to watch for critical situations, such as battery voltage. The IHU will turn the S-beacon off if the battery voltage drops to 26-volts This was the case recently due to a bad sun angle and a solar eclipse. The IHU automatically turned the beacon back on as these conditions ended. This may continue for the next few orbits as well. As predicted, AO-40 lost solar lock at the end of orbit 201 and the satellite was then officially in a hibernation state. The magnetorque system is off and will not be used until the satellite is in solar lock again. Although the SEU (sensor electronic unit) is not phase locked on the Sun, the Earth sensor continues to scan our planet. Four pictures were recently taken during orbit 207, at the time the satellite's view was the Gulf of Mexico. In addition, the IHU-2 clock was checked and found to be correct. The spin rate was at 2.047rpm. In looking at the downloaded pictures, it appears the spacecraft spins about 14 degrees during camera exposure (picture distortion was minimal). The Earth's edge can be seen in three of the received images and the angular distance from the bore-sight indicates an attitude of ALON 128 - ALAT 14. This estimate agrees with the Earth sensor. The AO-40 command team concludes that the camera and much of the IHU-2 unit is working correctly. The Earth sensor and camera mountings appear unchanged - and most importantly - the team now has a firm idea on the attitude direction of the spacecraft. 73, Peter DB2OS for the AO-40 command team [ANS thanks AMSAT-DL for this information] /EX SB SAT @ AMSAT $ANS-105.02 ISS PACKET SYSTEM ACTIVE AMSAT NEWS SERVICE BULLETIN 105.02 FROM AMSAT HQ SILVER SPRING, MD, APRIL 15, 2001 TO ALL RADIO AMATEURS BID: $ANS-105.02 The ARISS team reported to ANS that the packet system onboard Alpha has been activated. The have been several minor problems. ARISS team members have been debugging issues with the packet module over the past few months. The team is fairly certain that the TNC's RAM battery backup died shortly after the equipment was commissioned. ARISS been waiting for the Expedition crews to connect a laptop to the packet module to check out the system and re-install the packet parameters, including a callsign. To date, this has not happened due to the high workload the crews have been faced with. The bottom line is it appears that the packet system is alive and working well (and able to support APRS) but is operating without the parameters installed prior to flight. The ARISS team suggests those operators who are using the ISS packet system review the packet information found on the ARISS web site at: http://ariss.gsfc.nasa.gov/ The page has great pictures and written descriptions of the Amateur Radio equipment on-board ISS. The most common question the team has received recently is why can't we change the NOCALL to the ISS callsign? The ARISS group would love to do this. However, as stated above, the battery in the TNC has died and all the parameters, including the callsign, was then erased from the TNC RAM. The ARISS team plan is to install the callsign when the current crew has the time to connect a computer to the packet equipment and run a program to correct the default settings. Both the Expedition-1 and Expedition-2 crews have not had the time to accomplish this task. Also asked was what happened to the Cosmonautics Day voice operations? The only place the team heard that voice operations occurred during the Cosmonautics Day event was in Russia. The crew had the times of the contacts on their daily timeline but must have been too busy to reach for the radio. The ARISS team will continue to ask the crew to do random voice contacts whenever possible. The ARISS team is asking Amateur Radio satellite operators to be patient. The ARISS volunteers worked very hard to bring the initial hardware to fruition. From an operations standpoint, it will take a while before things start to settle out on ISS.

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 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.

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.

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. 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] 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.
