SB SAT @ AMSAT $ANS-065.01 PHASE 3D TENTATIVE LAUNCH AMSAT NEWS SERVICE BULLETIN 065.01 FROM AMSAT HQ SILVER SPRING, MD, MARCH 05, 2000 TO ALL RADIO AMATEURS BID: $ANS-065.01 AMSAT-DL's Peter Guelzow, DB2OS, broke the exciting Phase 3D news on February 29th, telling the Amateur Radio satellite community (via the AMSAT BB) that "it's official" -- the Phase 3D next-generation Amateur Radio satellite has been tentatively scheduled for launch in late July! The launch information is included in the Provisional Ariane Launch Manifest for February through July of this year. The manifest appears in the February edition of the Arianespace newsletter. The ARRL reports that if the schedule holds, the Phase 3D satellite would be sent aloft on Ariane 507, flight V132. AMSAT-NA President Keith Baker, KB1SF, was delighted with the news, "slowly but surely, Phase 3-D is moving ever closer to a launch. To finally see it listed on a launch manifest is a major milestone. Needless to say, we're most grateful for all the outstanding support we've been getting from the fine people at Arianespace!" Former AMSAT-NA President Bill Tynan, W3XO, echoed the statements, adding, "the recent news that Phase 3D has been designated for launch on AR-507 was indeed gratifying to all who have waited so long to hear such tidings. As the President of AMSAT-NA during much of the time the spacecraft was being constructed at our Orlando facility, I am especially pleased that the hard work of so many, for so long, is now coming to fruition. I look forward to meeting many of my friends on Phase 3D once it becomes operational." The Arianespace manifest identifies the other possible payloads aboard flight 507 as the PAS-1R (Europe Star) package and the STRV-1C/1D package. A launch contract accepting Phase 3D as a payload for the first suitable Ariane 5 launch vehicle was signed last October. The satellite is now at the European Spaceport in Kourou, French Guiana.

According to Cassini's imaging team, the little asteroid has a diameter of about 15 to 20 km. The asteroid was named for renowned planetary geologist Harold Masursky (1923-90). -S&T ** AMSAT-NA Journal Editor Russ Tillman, K5NRK, tells ANS the following articles are planned for the March/April issue - 'Phase 3D Travels to South America' by Peter Guelzow, DB2OS; 'Bare Bones L-Band Uplinks' by Mike Honer, W1BFN; the 'Launch of JAWSAT' by Cliff Buttschardt, K7RR, and 'Working Digital Satellites from Antarctica' by Ron Ross, KE6JAB. AMSAT-NA membership includes the Journal! -ANS ** A large naked-eye sunspot group appeared on the Sun recently and will gradually rotate out of the view during the next few days. It and other spots have been spewing gas and charged particle out into space recently, instigating modest alerts for possible geomagnetic activity. According to Cary Oler of the Solar Terrestrial Dispatch "there is considerable uncertainty concerning potential impact that the mass ejections observed might have on the Earth. Space weather forecasters are suggesting mostly active conditions may be observed, but with a possibility of minor to major geomagnetic storming." -S&T ** Florida Today is reporting that the currently unmanned Russian space station Mir is in the news again, with at least two rich Americans who want to turn Mir into a commercial platform that could do space business, accommodate millionaire tourists on vacation flings, or even serve as a moviemaking studio. -Florida Today ** The Cowley County Kansas Amateur Radio Club has a VHF/AMSAT Satellite net on Sunday evenings (8:00pm local) on the 145.190 MHz WA0JBW repeater. Rebroadcasting of the net takes place on the Internet along with a live chat room. More information is available at http://www.maincom.com/roundtable/index2.htm. Bill, W0OQC, does the Internet feed and takes checkins, NCS is Ron, N5SMJ. -Greg, N0ZHE ** It has been 13 years since the brightest supernova in centuries appeared in the Large Magellanic Cloud. The expanding debris of Supernova 1987A has been fading ever since, but astronomers have been anticipating a resurgence, as the outflowing gas collides with a ring of material believed to have been ejected 20,000 years before the original star exploded. In 1997, a bright knot appeared on the ring, indicating that the shock wave had arrived. Images taken by the Hubble telescope recently have revealed more hot spots. Peter Garnavich from the University of Notre Dame believes "the real fireworks show is finally starting, and over the next 10 years things will get spectacular." Astronomers expect the supernova remnant to become strong source of radio and X-ray emission. -S&T --ANS BULLETIN END--- /EX SB SAT @ AMSAT $ANS-065.05 WEEKLY SATELLITE REPORT PART 1 AMSAT NEWS SERVICE BULLETIN 065.05 FROM AMSAT HQ SILVER SPRING, MD, MARCH 05, 2000 TO ALL RADIO AMATEURS BT BID: $ANS-065.05 RADIO SPORT RS-13 Uplink 21.260 to 21.300 MHz CW/SSB Uplink 145.960 to 146.000 MHz CW/SSB Downlink 29.460 to 29.500 MHz CW/SSB Downlink 145.960 to 146.000 MHz CW/SSB Beacon 29.458 MHz Robot Uplink 145.840 MHz Robot Downlink 29.504 MHz Operational, in mode-KA with a 10-meter downlink and a 15-meter and 2-meter uplink. Kevin, AC5DK, reported "the shock of his satellite career" when after a stateside QSO during a pass of RS-13, he heard OK1DIG calling with a 559 signal. Both Dan and Kevin reported some flutter, but signals were strong through the bird. This was AC5DK's first over the horizon QSO!

Mike, N1JEZ, reports RS-15 is in a "real funky" mode. Mike says the beacon is active, but it's an unmodulated carrier on for 5 seconds, then off for 2 seconds, continually repeating the cycle. The transponder is only active when the beacon is on! Despite this Mike reports downlink signals were S-3 to S-5. Dave, WB6LLO, has operating information for both RS-15 and RS-13 on his web site. In addition to satellite data, antenna information for mode-A operation is also featured.

AO-10 has been locked into a 70-cm uplink and a 2-meter downlink for several years. DX continues to be worked (and heard) on AO-10. Eddie, DU1EV, has been active. Jeff, K7XQ, worked AO-10 using his mobile station, reporting contacts with W6VPH and KB8VAO. The antennas were both single band loops mounted on his vehicle. He also worked XE2YVW, VE6EGN, N6KMR, K5OE, K6YK on AO-27 using the same setup.

Tony, W7EWC, tells ANS he plans to be active on AO-27 from the Bahamas as W7EWC/C6A during the entire month of March. John, KD7DEZ, will be portable (March 11-12th) from (CN78) Cape Alava, Washington (the most western point of the contiguous United States). He will be hiking and camping with a Boy Scout Troop and will attempt contacts on AO-27, SO-35 and UO-14. Al, XE2YVW, recently operated from DL70 and DL90. 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. The AO-27 pages on the AMSAT-NA web site include an explanation of AO-27 operations (at): http://www.amsat.org/amsat/sats/n7hpr/ao27.html Chuck, KM4NZ, recently reset the TEPR states on AO-27 (on 02/12/2000).

Chris Jackson, G7UPN / ZL2TPO reported on the AMSAT bulletin board that UO-14 --launched in January 1990-- spent its first 18 months in orbit operating as an Amateur Radio store-and-forward satellite. It was then switched for use by Volunteers in Technical Assistance, who used it for medical messaging into Africa. "Since the computer which is used for store-and-forward communications is no longer able to perform that task, UO-14 is no longer usable in this mode," reported G7UPN. "It is, however, possible to use the satellite as a single-channel FM voice repeater, and I have configured the satellite to do this." Mike, N1JEZ, reports a nice roundtable with CT1EAT, G1OCN and VE2VB. Osmar, LU7FQU, worked CX6DD. Malc, G7NFO, worked VE2VB. Dirk, ON1DLL, reports good luck using UO-14 with his portable station.

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, recently celebrating its first year in orbit. 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. Mike, N1JEZ, reports that SO-35 has been active in Parrot mode. This is simplex operation and Mike suggests to monitor 145.825 MHz and listen for a single beep tone followed by 10 seconds of silence. This is when SO-35 is in 'record' mode and digitally stores what it hears. Immediately after this SO-35 plays back what it captured in the previous 10 seconds. The cycle then repeats. Mike says "it takes a little getting used to" -- but he did make 2 contacts this way. Peter, G4AJG/4S7PE, will be in Sri Lanka until mid-March and the SunSat team is making the satellite available for Peter's operations from that area.

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.

Clive Wallis, G3CWV, reports that during the period of 15-January to 15-February good signals have been received from the 145 MHz beacon. 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. The operating schedule is as follows: ASCII status (210 seconds) ASCII bulletin (60 seconds) BINARY SEU (30 seconds) ASCII TLM (90 seconds) ASCII WOD (120 seconds) ASCII bulletin (60 seconds) BINARY ENG (30 seconds) The ASCII bulletin is currently a static message, detailing modes and frequencies of all active amateur radio satellites.

Russ, WJ9F, reports ground stations are currently running memory test software on the satellite. After loading the file server software the satellite reverted back to MBL mode after about 3 minutes. Russ and his team are evaluating if a write to memory glitch may have caused the problem. In addition to the memory testing, the spacecraft spin rate around the vertical (Z) axis has created a less than ideal condition for battery charging. The S-band transmitter is currently off. Kazu, JJ1WTK, reports the AO-16 signal is weaker than before but perfectly decodable. The JJ1WTK spin rate measurement is also on going. The current spin rate is about 18 revolutions per minute.
