SB SAT @ AMSAT $ANS-345.01 PHASE 3D/AO-40 UPDATE
AMSAT NEWS SERVICE BULLETIN 345.01 FROM AMSAT HQ SILVER SPRING, MD, DECEMBER 10, 2000 TO ALL RADIO AMATEURS BID: $ANS-345.01
General housekeeping tasks continue underway as ground stations test the complex systems onboard AMSAT OSCAR-40. Magnetorquing operations have also continued this past week.
North American P3D Command Station operator Stacey Mills, W4SM, reports both S-band transmitters (S-1 and S-2) has been activated recently. The S-band transmitters will be activated when reasonable squint angle and visibility are available. ANS reminds all ground stations that doppler correction at S-band frequencies and at this point in the orbit will be dramatic.
Greg, NьZHE, reports the S-2 beacon was heard at his QTH with good signals using a Drake downconverter and a homebrew 20 turn helix. Bill, WA2TQI, also reports good signals using a dish and a Drake downconverter. "Signals where running 3 to 4 S-units above the noise," said Bill, "and I was able to read telemetry intermittently."
Several stations have noted the recent IHU-2 software crashes indicated by downlinked telemetry. AO-40 command station operator James Miller, G3RUH, comments: "IHU-2, which is repeating the IHU-1 information, has crashed recently. The data is a diagnostic dump of CPU registers, stacks etc. I reset IHU-2." James also reports that " there is at least one command station monitoring AO-40 all the time. We don't miss much!"
Any IHU-2 software crash is not considered to be a serious problem by the AO-40 team.
The current focus on AO-40 is the orbital parameter change involving the 400N onboard engine. This first burn unofficially took place on December 11th at 04:14 UTC, with a second burn also planned. As this edition of ANS is released, the success or failure of the burn events were not available from the AO-40 command team. Stay tuned to ANS for full details as they become available.
Jim, WD0E, reported to ANS that the RUDAK experiment aboard AO-40 was powered on for the first time recently. According to WD0E the RUDAK team (in Colorado) was able to command AO-40 to bring up the level on one of the RUDAK 9k6 modulators "and we were able to hear it via the S-2 transmitter." Jim reports this is the first step in a long process to test all the RUDAK subsystems. In addition to its packet-radio-service communication, RUDAK is the key to experiments like SCOPE, GPS, CEDEX and RF-Monitor.
RUDAK frequencies may be changed during the commissioning process (without prior announcement), currently they are:
RUDAK-A 2401.747 and 2401.720 MHz RUDAK-B 2401.867 and 2401.847 MHz
The GPS equipment supported by RUDAK will be tested and checked out as power, pointing angles, and other primary 'bus' commissioning activities allow. The GPS units should provide interesting information about the satellite, including element and attitude data. Jim wisely points out that "this assumes all the bits and pieces work. The GPS equipment is very much an experiment."
RUDAK team member KB0G announced the availability of an updated set of web pages with information about the RUDAK digital communications system aboard AO-40. Access the material from the link on the AMSAT page or view the RUDAK information directly at:
http://www.amsat.org/amsat/sats/ao40/rudak/index.html
There is another (new) AO-40 web page, dealing with getting started on AO-40, and general help in receiving AO-40 telemetry. Check out this new information at:
http://ao40.homestead.com

SB SAT @ AMSAT $ANS-345.02 ARISS UPDATE
HR AMSAT NEWS SERVICE BULLETIN 345.02 FROM AMSAT HQ SILVER SPRING, MD, DECEMBER 10, 2000 TO ALL RADIO AMATEURS BID: $ANS-345.02
The ARRL is reporting that ARISS delegates have ratified new bylaws and elected officers during a meeting held recently at Goddard Space Flight Center in Maryland.
Delegates from the United States, Russia, a consortium of European countries, Canada and Japan elected AMSAT's Frank Bauer, KA3HDO, to chair the ARISS Board. European Sub-regional Working Group Chairman Gaston Bertels, ON4WF, was chosen as Vice Chair. ARRL Field and Educational Services Manager Rosalie White, K1STO, was elected Secretary-Treasurer. All will serve for two years. Congratulations to all from AMSAT News Service!
ARISS delegates also approved a QSL card that features a beautiful color photograph of the orbiting station and a Russian proposal to send up a higher-power mobile transceiver to be installed in the Zvezda Service Module. A proposal to activate Slow-Scan TV was also reviewed.
On the communications front, Randy Shriver, KG3N, of Hanover, Pennsylvania managed to snag the first informal contact with ISS crew commander William Shepherd, KD5GSL. The contact took place on November 13th as Shepard completed an 'engineering pass' contact with NN1SS. KG3N dropped in a quick call, and Shepherd came back to him using his own call sign.
Students at the Luther Burbank School in Burbank, Illinois, will get a chance to speak with the crew of Space Station Alpha very soon. AMSAT's Will Marchant, KC6ROL, says the contact is scheduled to take place on December 19th. "I've just been told that the Burbank school contact is confirmed for Tuesday," said KC6ROL, adding, "remember that this is contingent upon normal operations on orbit... but, everything looks good!" Efforts are under way to set up a Web-cast of the contact.
Another 18 schools are under consideration for ARISS school contacts.
The Discovery Channel aired a program that most Amateur Radio satellite operators found very interesting. 'Inside the Space Station' initially was broadcast on Sunday, December 10th. The program mentions the ARISS program and the ham gear aboard ISS. In case ANS readers missed it, the program repeats in North America on December 17, 18 and 23, 2000. Check local listing for times, or visit the Discovery Channel web site for details at:
http://www.discovery.com/stories/science/iss/iss.html
KC6ROL has added new links with more details about the upcoming school contact, the ARISS partners meeting, and the new NASA web page about Amateur Radio. Check it out at:

SB SAT @ AMSAT $ANS-345.04 ANS IN BRIEF
HR AMSAT NEWS SERVICE BULLETIN 345.04 FROM AMSAT HQ SILVER SPRING, MD, DECEMBER 10, 2000 TO ALL RADIO AMATEURS BID: $ANS-345.04
ANS news in brief this week includes the following:
** AMSAT has several satellite awards available including some that are QSL-free, (such as the W4AMI Satellite Operator Achievement Award). See http://www.amsat.org/amsat/awards/awards.html for details. -Paul, KB5MU
** The ARRL's Joe Moell, K0OV, says hams in the Central U.S. had an unusual form of public service as many have been listening just above 172 MHz for brief transmissions from radio tags on 52 endangered burrowing owls. The rare birds have left Saskatchewan and Alberta for warmer weather in southern Texas and northern Mexico. Now that the fall migration is complete, hams in Texas and surrounding states are being asked to monitor for the tags this winter. For details on owl-tracking efforts, visit http://www.homingin.com. -ARRL
** President Clinton has signed legislation that permits the enforcement of certain FCC Citizens Band regulations by state and local governments. Amateur Radio operators are exempt from the provisions of the law, now PL 106-521. -ARRL
** Pat, N8PK, reports the recent shuttle launch was "the third time I've seen it from Maryland and this was the longest and brightest to date." Pat says the launch actually had some color to it as well, a little bit of orange and red. According to the commentator on shuttle re-transmission station WA3NAN - pat reports that it was travelling at about 4,000 mph and climbing when he saw it. -Pat, N8PK
** ON1CAU has updated his web site with AO-40 related information and audio from the V-band beacon -- recorded by YB4JIM, NP2L, N8TDL and ON1CAU using three different formats. Checkout the site at the following URL: http://users.skynet.be/on1cau/. -Berto, ON1CAU
** As Christmas approaches, the brilliant 'evening star' Venus will shine close to a thin crescent Moon during and after twilight. The sight will be a head-turner -- a beautiful celestial display worth making a special note to see. -SpaceDaily
** The Times of India newspaper reports recently that cheap cordless telephones imported illegally are causing havoc on VHF frequencies including interference with Amateur Radio satellites. CQ magazine has more details at: http://www.cq-amateur-radio.com. -Rich, W2VU
** AMSAT-NA President VE3FRH was asked just what he wanted for Christmas... and replied "some of us have a problem in deciding what we want for Christmas, and I thought a one year membership in AMSAT (or more) along with various AO-40 related premiums might be a good idea!" ANS agrees! Another way to help with AO-40 funding is with a donation by ordering the 1:20th scale, fully detailed display model kit of Phase 3D. Call Martha at 301-589-6062 for details. -NN0DJ
** The Spacewatch Project at the University of Arizona has discovered a minor planet in the outer reaches of the solar system which appears to be the brightest known such object other than Pluto. -SpaceDaily

Much confusion concerning the status of RS-12 and RS-13.
Kevin, AC5DK, and Jerry, K5OE, have provide the following information in order to clarify the current situation:
RS-12: recently both 2 and 10-meter beacons have been on (intermittent 10-meter beacon).
RS-13: in mode T (not mode KT). The 2-meter beacon is on (145.860 +/-) and the mode-T robot is on and working/replying. (The uplink/downlink frequencies shown above are accurate --ANS).
The latest information on RS-12 and RS-13 can be found on the AC5DK RS-12/13 Satellite Operators page at:

AMRAD AO-27 Uplink 145.850 MHz FM Downlink 436.795 MHz FM Launched: September 26, 1993 by an Ariane launcher from Kourou, French Guiana 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. The current TEPR settings (as of November 25, 2000) are:
TEPR 4 18 TEPR 5 36

SB SAT @ AMSAT $ANS-345.06 WEEKLY SATELLITE REPORT PART 2
AMSAT NEWS SERVICE BULLETIN 345.06 FROM AMSAT HQ SILVER SPRING, MD, DECEMBER 10, 2000 TO ALL RADIO AMATEURS BT BID: $ANS-345.06
TIUNGSAT-1 Uplink 145.850 or 145.925 MHz 9600 baud FSK Downlink 437.325 MHz Broadcast callsign MYSAT3-11 BBS MYSAT3-12 Launched: September 26, 2000 aboard a converted Soviet ballistic missile from the Baikonur Cosmodrome Status: Operational, 38k4 baud FSK
Chris, G7UPN, tells ANS that recently, 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.
CT1EAT reports that "after tracking TiungSat-1 all I can say is this bird is amazing! A few seconds after AOS the efficiency reach 100% and kept that value until LOS! Thank you for the privilege to use a satellite like this!"
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.

OSCAR-11 Downlink 145.825 MHz FM (1200 baud AFSK) Mode-S Beacon 2401.500 MHz Launched: March 1, 1984 by a Delta-Thor rocket from Vandenberg Air Force Base in California Status: Operational
OSCAR-11 celebrated its sixteenth birthday in space on March 1, 2000.
During the period through November 14, 2000 good signals have been received from the 145 MHz beacon as the satellite is currently seeing good solar conditions which should continue until the end of the year. Ground control stations have reset the magnetorquer counters, the spin period has varied between 217 and 276 seconds. The battery voltage observed during daylight passes is unchanged with an average value of 14.0, with a range of 13.9 to 14.1 volts. Internal temperatures have increased slightly and are probably near maximum value. They are now 6.6 C and 4.8 C for battery and telemetry electronics. A single WOD survey of dated 06-October-2000, has been transmitted. The mode-S beacon is transmitting an unmodulated carrier. The beacon is a useful test source for mode-S converters. The 435.025 MHz beacon is normally off but can sometimes be heard when the satellite is being commanded by ground control.
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.

TMSAT-1 TO-31 Uplink 145.925 MHz (9600 baud FSK) Downlink 436.925 MHz (9600 baud FSK) Broadcast Callsign: TMSAT1-11 BBS TMSAT1-12 Launched: July 10, 1998 by a Zenit rocket from the Baikonur Cosmodrome Status: Operational
Jim, AA7KC, reports nominal TO-31 operation, with moderate traffic and continuing new images.
ProcMail V2.00G has been released by G7UPN. This software permits the processing of image files from TO-31. It has been posted to the AMSAT-NA FTP site at the following URL:
http://www.amsat.org/amsat/software/win32/wisp
Many of the high-resolution color images transmitted by TMSAT are compressed using a UoSAT compression format. This format is supported by the VK5HI CCD display program.

UoSAT-12 UO-36 Uplink 145.960 MHz (9600 baud FSK) Downlink 437.025 MHz 437.400 MHz Broadcast Callsign UOSAT12-11 BBS UOSAT12-12 Launched: April 21, 1999 by a Russian launcher from the Baikonur Cosmodrome Status: Operational
UO-36 carries a number of imaging payloads, digital store-and-forward communications and mode L/S transponders.
NASA has demonstrated on UO-36 the ability to use standard Internet protocols to communicate with an orbiting spacecraft (just like any node on the Internet). NASA has been developing this project by working with the commercial payload aboard UoSAT-12.
The BBS is open, although uploading and downloading may be disabled at times.
The VK5HI viewer shareware for UO-36 is available on the AMSAT-NA web site at the following URL:
