Phase 3D/AO-40 Update

The month of January continues with command stations working in their on-going recovery efforts of AMSAT OSCAR 40. The command team has determined the following:

* The V-band, U-band and the L-band (L1) receivers are working on the the high-gain antennas. The omni-directional antennas appear to be non-functional. The command team's conclusion is that damage has been sustained to the omni-directional antennas, antenna cables or antenna relays (or possibly all three).

* An attempt to command the V-band transmitter on the high-gain antennas has been done several times with no downlink signals detected. Telemetry may be indicating the transmitter is working, but with the current position of the satellite, V-band signals may not be receivable due to the assumption that the high-gain antennas may be pointing into space and not at Earth. Further tests will be conducted.

* No recent tests have been conducted on the U-band transmitter, but tests are planned once the current spin rate is reduced and the command team can confirm the heat pipes are working.

* The attitude control system is fully functional. Currently, a high spin rate (of about 17rpm) and an extreme sun angle (about 60 degrees) does not allow the sun sensor to provide accurate information. This explains why the indicated spin rate (via telemetry) is inaccurate. Without sun and attitude information the command team has suspended magnetorquing efforts, thus no further attitude or spin change has been attempted recently. Project leader DJ4ZC is developing a software algorithm which does not use sun sensor information. This software program will be tested and then used to try and reduce the spin rate and move the spacecraft to a better attitude.

In summary, once the sun angle and antenna pointing is improved, both the V-band and U-band transmitter tests can resume, along with suitable experiments of the ATOS (arc-jet) thruster and the momentum wheels.

ALON/ALAT is currently 248/-7, as listed on the AMSAT-DL web page.

Several stations, including AO-40 command station G3RUH have measured the frequency of the S-2 transmitter middle beacon as 2401.323 MHz. The beacon can be heard before perigee (between MA 245 and 256). Due to extremely high Doppler shift coupled with spin wobbling and fading, error-free telemetry reception will be difficult.

Moe Wheatley, AE4JY, has released an updated of his AO40RCV soundcard-demodulator. Data export and AFC have been improved, recorded sound files can be used and triggering up/down keys of (most common) transceivers for automatic doppler correction has been implemented. More information on AO40RCV is available at http://www.qsl.net/ae4jy

DJ4ZC Named Marburger of the Year

AMSAT-DL President and AO-40 project leader Dr. Karl Meinzer, DJ4ZC, was recently named 'Marburger of the Year 2000' by readers of the Oberhessische Press, a daily newspaper published in Karl's hometown Marburg, Germany.

Nine Marburg residents were nominated.

The AMSAT-DL President's chief involvement in the development of AMSAT OSCAR 40 was mentioned in the honor. "This honor isn't only my merit," said Karl, "it also belongs as well to my colleagues all over the world and the many who are involved in the AO-40 project."

Speaking on behalf of the AMSAT-NA Board of Directors, Officers and members of AMSAT-North America, AMSAT-NA President Robin Haighton, VE3FRH, told ANS:

I congratulate Karl on being voted as the 'Marburger of the Year 2000'. His outstanding technical expertise and hard work in leading the P3D team, I am sure, contributed toward this award. However, I am equally sure that Karl's work in his hometown and with the University of Marburg surely played a significant role in this achievement.

Karl, your friends on this side of the Atlantic salute you and your award and wish you and your family continued success in 2001.

73,
Robin Haighton, VE3FRH
President AMSAT-NA

[ Congratulations DJ4ZC - from ANS! ]

President's Letter

Several times each year ANS will feature information from AMSAT-NA President Robin Haighton, VE3FRH. This feature is known as the 'President's Letter'. The following is the latest installment:

In the days of AO-13, I operated S-band with a good downconverter (with 2-meter IF). I had some outstanding results, the signal quality was Q-5 and the signal strength was usually S-7 from a satellite putting out less than 1-watt into a unity gain antenna (and at great distance). There was no detectable background noise and the copy was usually 100%.

Unfortunately, my downconverter suffered the ravages of weather and I purchased another one in early December 2000. Living in Canada, we have certain weather conditions which are not always cooperative with putting up antennas and associated equipment. However, this last week enough snow had melted to enable me to gain access my roof and to install my new equipment.

The installation went well (I had prepared the cables and connectors ahead of time) and it only took a short time to put everything in place. Unfortunately, once I had everything working I found I had missed the AO-40 pass for that day.

Last Wednesday morning I went to the ham shack and turned on the converter, tuned the rig to the appropriate frequency and with the aid of WISP found the satellite on my first try. Ah yes - the joy of receiving AO-40 (again) and watching the telemetry come through on my computer screen was a real pleasure. This time the signal strength was S-9 and the quality was excellent - in spite of a poor offset angle between my antenna and the satellite.

I note that the signal will cut off when antennas can no longer see each other, but reasonable copy can be expected between MA-3 and MA-12 (according VP9MU). My next opportunity to be connected to AO-40 is January 22nd, early in the morning from this QTH. You can be sure that I will be there, collecting data for the archives and sending it to the AO-40 archive data base (ao40-archive@amsat.org).

If you are not currently listening to the S-band transmissions from AO-40, I invite you to put some equipment together and join me!

Latest ISS School Contact Successful

Students at the Sheldon Elementary School made a long-distance trip into outer-space this past week by amateur radio, talking with astronaut William Shepherd aboard the International Space Station.

The students asked Shepherd several questions, including whether the stars looked any different from outer space, what Shepherd saw passing by the ISS windows and what he does with his spare time. One pupil who was particularly happy to speak to Shepherd was Eliza Stringham. She is Shepherd's niece.

During the time the pupils were speaking to Shepherd, the space station traveled over western Canada toward the Atlantic Ocean near South Africa.

Amateur radio equipment on the International Space Station is a project of ARISS, and is made up of delegates from major national amateur radio organizations, including AMSAT.

More information about the project can be found on the ARISS web site at http://ariss.gsfc.nasa.gov.

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 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.

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.

OSCAR-11

Downlink 145.825 MHz FM, 1200 baud PSK
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.

During the period of 16-December 2000 to 16-January, 2001 good signals have been received from the 145 MHz beacon. OSCAR-11 users should note that the year displayed in the ASCII status blocks is incorrect. There is currently a similar error of one year in the date of the latest WOD survey. Ground control should be able to correct these errors shortly.

Battery voltage observed during daylight passes is unchanged. The average value observed was 14.0, with a range of 13.7 to 14.1 volts. Internal temperatures have continued to decrease by one degree as the eclipse periods lengthen. They are now 5.02 and 3.2 C for battery and telemetry electronics respectively.

The spin period has varied between 256 and 311 seconds. Two positive magnetorquer correction pulses and zero negative pulses have been counted, while there have been 324 Z-axis correction pulses.

S-band reception reports have been received recently from K5OE, PE5YES and W9JIU.

The operating schedule is unchanged.

Beacon 145.860 MHz
Launched February 5, 1991 aboard a Russian Cosmos C launcher

Status: non-operational (last operational in mode-T)

RS-12 was apparently re-activated recently. Prior to this switch RS-13 was operational (mode T), but was apparently turned off following the recent RS-12 switch.

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

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. 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 now underway.

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:

http://www.sp.nps.navy.mil/pansat/

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.
