Phase 3D/AO-40 Update

The news received on Christmas day was what everyone wanted to hear -- AO-40 is transmitting again! Prior to this confirmation, the satellite had not transmitted any signals since December 13, 2000, which was shortly after the first burn of the 400-N motor.

On December 25, 2000 at 21:45 UTC command station ZL1AOX transmitted a L-band reset command which included an initialization block to switch 'on' one of the two S-band transmitters onboard AO-40. Just after the first attempt, AO-40's S-2 beacon was received by Ian, ZL1AOX. The S-band signal strength was S-5 to S-6, which compared to S-2 when the beacon was last heard last during testing in early December. AO-40's S-band transmitter produced a steady signal at ZL1AOX and from the doppler wobbling it was also clear that it was in fact coming from AO-40.

AMSAT-NA President Robin Haighton, VE3FRH, received the news with much relief:

"The excellent news of contact with AO-40 through the L-band uplink and S-band downlink has been received with joy and relief by AMSAT members around the world. AMSAT-DL issued a bulletin giving the news that everyone had hoped for on Christmas day, a fantastic gift to the Amateur Radio community."

VE3FRH also added the following comments:

"The command team has not stopped their investigation during the holidays. The AO-40 the team have now started to receive good telemetry data from the bird via the 2400 MHz S-band transmitter. However, copy is only available during the earliest part of each pass (typically MA 14-39) due to the offset of the antenna with respect to Earth. This restricts the amount communication that can take place during each pass. The data that has been recovered is being analyzed very carefully to try and determine a number of things," (such as):

"When questions such as these (and others) are answered, it may be possible to determine the working capability of the spacecraft, and, if appropriate, to start to try operation on other bands. Much analysis work remains to be completed and I know that the command team will try to keep us all informed as and when they can answer the questions. Over the next week or two some critical decisions will be made, these decisions will be based on the results of the analysis and much discussion among the command team. Meanwhile, lets hope that the first week or two of the New Year will bring the same joy and relief to us all as the initial news of December 25th."

ANS earlier reported that on December 26th, ZL1AOX succeeded in loading IPS flight software and a minimal operational package into AO-40 and the satellite began sending telemetry (A blocks) that enabled initial analysis of the status of the spacecraft.

AMSAT-DL President Dr. Karl Meinzer, DJ4ZC, reviewed the received telemetry:

"A first (quick) look has revealed that some temperature sensors and possibly some current sensors have been lost by whatever incident caused the telemetry transmissions to stop. However, the power situation, in particular the battery voltages, look nominal.

We will now start a detailed analysis of the situation; the command stations will continue to follow a conservative philosophy with the primary target of not causing any additional damage along with retaining as much evidence as possible for the analysis of the incident."

DJ4ZC reported to ANS that recovery efforts of AO-40 will continue, mainly centered around housekeeping tasks designed to improve and stabilize the systems onboard the satellite. Several new software routines were successfully loaded that restored all Battery Charge Regulator functions and have resulted in a positive power budget. AO-40 has new flight software (with the exception of D-block programming and WOD routines which will be done later).

Command station G3RUH (James Miller) reported that commanding AO-40 on L-band frequencies was fairly easy, thus it appears the L-band receiver seems to be work nominally.

Recent telemetry instrumentation shows Helium pressure at essentially where it was following the first 400-N motor burn. Also, it appears that a few temperature and current sensors either failed and/or are showing incorrect values. The onboard sun sensors appear to be fine and are showing a solar angle that is near predictions.

Received spin rate telemetry is not accurate when compared to the actual spin as measured by the doppler wobbling of the S-band beacon. A substantial spin increase is noted and the P3D team is working to analyze and understand what has happened here.

As Peter Guelzow, DB2OS, reported to ANS; "the good news is that the spacecraft is now fully under control. During the next several days additional software will be loaded and the various uplinks will be verified."

AMSAT-DL's Frank Sperber, DL6DBN/AA9KJ, placed the following statement on the AMSAT-DL web site:

We wish you a happy new year which hopefully will bring back AO-40 to a substantial life. Thank you for your kind wishes and support. Both are very welcomed in these nervous times of AO-40's recovery. We'll try to keep you informed about the progress as best we can beside work and family.

Stay tuned to ANS, the official source of information on AMSAT OSCAR 40.

New OSCAR Numbers Announced

ANS has received a copy of a letter sent to Dr. Turki Al Saud, the director of space research at the King Abdullaziz City for Science and Technology, the sponsoring agency of two of Amateur Radio's newest satellites, SaudiSat 1A and 1B.

The letter is written by AMSAT-NA (past) President Bill Tynan, W3XO:

In accordance with the request by AMSAT-NA President Robin Haighton, VE3FRH, that I be charged with the issuance of OSCAR numbers to qualifying Amateur Radio satellites (and) in response to a request for OSCAR numbers for SaudiSat 1A and 1B, which correspond to the provisions set forth in the following IARU document:

'Information For Perspective Operators of Satellites Utilizing Frequencies Allocated to the Amateur Satellite Service',

I do hereby designate SaudiSat 1A as Saudi OSCAR 41/SO-41 and SaudiSat 1B as Saudi OSCAR 42/SO-42.

Congratulations to all who worked on this project on the launch of these spacecraft. I am sure that the world's Amateur Radio community will very much appreciate having SO-41 and SO-42 available for use.

Sincerely,
William A. Tynan, W3XO

SaudiSat 1A and 1B were launched September 26, 2000 aboard a converted Soviet ballistic missile from the Baikonur Cosmodrome. Currently, both satellites are in their commissioning stage, with initial housekeeping tasks underway. Each satellite will operate as a 9600 baud digital store-and-forward system as well as an analog FM (bent-pipe) repeater.

Congratulations from ANS!

V-band Beacon 145.898 MHz
S-Band transmitters: operational at certain times
Launched: November 16, 2000 aboard an Ariane 5 launcher from Kourou, French Guiana. A 50-second video of the launch can be seen at: http://arianespace.com/interior/v135better.mov
Status: S-Band transmitter is active, recovery efforts continue

Paul, VP9MU, reports the S-2 published beacon frequency of 2401.350 MHz may be misleading as the actual frequency has not been calibrated. VP9MU reports that from various reception reports it would appear that using 2401.318 MHz may be a good starting point. ANS reminds stations that at S-band frequencies doppler will be dynamic.

RS-13

Uplink 21.260 to 21.300 MHz CW/SSB
Downlink 145.860 to 145.900 MHz CW/SSB
Beacon 145.860 MHz
Launched February 5, 1991 aboard a Russian Cosmos C launcher

Operational, mode T

Kevin, AC5DK, reported to ANS that "questions continue to come into the RS-12/13 forum. Most problems still stem from incorrect Mode T downlink frequencies. What further compounds the problem is that the RS-12 upper beacon is being confused with the RS-13 lower beacon, but in actuality it is 100 kHz lower."

AC5DK adds "I would also like to remind everyone to always Doppler adjust the higher frequency when using RS-13; in this case it's the 2-meter receive frequency. I suggest never adjusting the 15-meter uplink as you may QSY into an ongoing terrestrial QSO and become unwelcome QRM... and always listen on your uplink frequency before transmitting."

The latest information on RS-12 and RS-13 can be found on the AC5DK RS-12/13 Satellite Operators page at http://www.qsl.net/ac5dk/rs1213/rs1213.html

AO-27

Uplink 145.850 MHz FM
Downlink 436.795 MHz FM
Launched September 26, 1993 by an Ariane launcher from Kourou, French Guiana
Operational

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: 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

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

TIUNGSAT-1

Uplink 145.850 or 145.925 MHz 9600 baud FSK
Downlink 437.325 MHz
Broadcast callsign: MYSAT3-11
BBS: MYSAT3-12
NUP: MYSAT3-10
Launched September 26, 2000 aboard a converted Soviet ballistic missile from the Baikonur Cosmodrome
Status: Operational in digital mode, currently at 9600 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.

TiungSat-1 is Malaysia's first micro-satellite and in addition to commercial land and weather imaging payloads will offer 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.

Beacon 2401.500 MHz
Launched March 1, 1994 by a Delta-Thor rocket from Vandenberg Air Force Base in California
Operational.

OSCAR-11 celebrated its sixteenth birthday on March 1, 2000.

The G3CWV OSCAR-11 report for December shows "once again it's been an uneventful month for OSCAR-11. Good signals have been received from the 145 MHz beacon and the satellite is experiencing good solar conditions that should continue until the end of the year."

The battery voltage observed during daylight passes is unchanged with the average value observed at 14.0, with a range of 13.9 to 14.1 volts. Internal temperatures have now started to decrease slightly as the eclipse periods start to lengthen. The spin period has varied between 218 and 299 seconds. Seven positive magnetorquer correction pulses and zero negative pulses have been counted and there have been 281 Z-axis correction pulses.

The operating schedule is unchanged.

TMSAT-1 TO-31

Uplink 145.925 MHz 9600 baud FSK
Downlink 436.925 MHz 9600 baud FSK
Launched July 10, 1998 by a Zenit rocket from the Baikonur Cosmodrome
Operational.

Chris G7UPN, (UoSAT operations manager) reports the following to ANS:

Over the next few days - or possibly couple of weeks - the TO-31 downlink will be off over most areas, with the exception of Europe and Thailand. This is required to allow control stations to recondition the battery with minimum power drain. I am trying to get this moving as quickly as possible however with Christmas holidays it may take slightly longer than normal.

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 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.

The following satellites are in orbit but are non-operational at this time:

KITSAT KO-23

Uplink 145.850, 145.900 MHz FM
Downlink 435.175 MHz FM, 9600 Baud FSK
Broadcast callsign: HL01-11
BBS: HL01-12
Launched August 10, 1992 by an Ariane launcher from Kourou, French Guiana
Status: Intermittent operation with the downlink transmitter operating at unpredictable intervals

Jim, AA7KC, reports that KO-23's downlink transmitter continues in non-operational status. 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.

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 now underway.

RS-12

Uplink 145.910 to 145.950 MHz CW/SSB
Uplink 21.210 to 21.250 MHz CW/SSB
Downlink 29.410 to 29.450 MHz CW/SSB
Downlink 145.910 to 145.950 MHz CW/SSB
Beacon 29.408 MHz
Robot Uplink 21.129 MHz, Downlink 29.454 MHz
Launched February 5, 1991 aboard a Russian Cosmos C launcher

Status: unconfirmed

ANS has received reports from several stations that the 29.408 MHz RS-12 beacon has been heard. The beacon telemetry indicated that both the 10 and 2-meter receivers aboard RS-12 are currently off.

Jerry, K5OE, reports both the 2 and 10-meter beacons have been heard at his QTH, (although the 10-meter beacon has been intermittent).

TechSat-1B GO-32

Downlink 435.225 MHz, HDLC telemetry
Launched July 10, 1998 by a Russian Zenit rocket from the Baikonur Cosmodrome
Semi-operational.

Efforts were reported to be underway to bring GO-32 on line, however no additional 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 frequencies have never been released.
Launched October 30, 1998 by the Shuttle Discovery
Status: unknown

The satellite is not currently 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:

PanSat was the featured cover article in the July/August 1999 issue of the AMSAT-NA Journal (written by KD6DRA and N7HPR).

ANS has no further information.

Mir Space Station

145.985 MHz simplex FM voice and SSTV (Robot 36 mode)
Launched February 18, 1986
Unmanned.

MIR SAFEX II 70-cm Repeater
Uplink 435.750 MHz FM w/subaudible tone 141.3 Hz
Downlink 437.950 MHz FM
Not operational. No operation in 1999 or 2000 has been observed.

MIR SAFEX II 70-cm QSO Mode
Uplink 435.725 MHz FM w/subaudible tone 151.4 Hz
Downlink 437.925 MHz FM
Not operational. No operation in 1999 or 2000 has been observed.

Currently, there is no human habitation aboard the station and the amateur radio equipment has been turned off. Several news agencies have reported that Mir in now on 'autopilot'.

Several news agencies are reporting the Mir space station will be ditched this coming February in a controlled descent that will send it hurtling into a remote area of the Pacific Ocean.

Stay tuned to ANS for further details.

DO-17 (DOVE)

Downlink 145.825 MHz FM, 1200 Baud AFSK
Beacon 2401.220 MHz
Launched January 22, 1990 by an Ariane launcher from Kourou, French Guiana
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
Non-operational.

WO-18 was last reported to be in MBL mode after a software crash.

ANS has no further information.

SEDSAT SO-33

Downlink 437.910 MHz FM 9600 Baud FSK
Launched October 24, 1998 by a Delta 2 rocket from Cape Canaveral in Florida
Semi-operational.

The satellite is not currently available for uplink transmissions and 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.
