AO-40 UPDATE
AMSAT NEWS SERVICE BULLETIN 175.01 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 24, 2001
TO ALL RADIO AMATEURS
BID: $ANS-175.01
The ARRL is reporting that although AO-40 satellite's transponders are
still shut down, ground controllers have successfully activated the ATOS
propellant feed system. According to received telemetry, the ammonia
heater, flow-rate controller, valves and pressure indicators all worked
successfully. "Congratulations to the command team for another superb
job!" exulted AMSAT-DL President and AO-40 team member Peter
Guelzow, DB2OS.
For the first cold test, the gas was warmed by a 120-watt heater and
flowed for approximately 22 minutes. Since AO-40's solar panels have
not been fully deployed, no electric current was applied.
AMSAT-NA President Robin Haighton, VE3FRH, told the ARRL the
orbital changes will not significantly change the apogee, but it's hoped
that a slightly higher perigee for AO-40 will eliminate the effects of
atmospheric expansion caused by the current sunspot cycle peak.
AMSAT-DL reported to ANS the first test was done without electrical
power by blowing only cold gas to check-out all systems and raise the
perigee by some hundred kilometers. Telemetry confirmed that the
heater for the ammonia, the flow rate controller, valves and pressure
indicators all worked successfully.
Pictures were also taken by the YACE camera, downloaded on orbit 292,
processed and analyzed.
Following the initial success, the Arc-jet thruster was commanded to
again out-gas during orbit 296, this time with a duration of one hour in
length. This test also was successful.
The AO-40 command team then loaded data to the onboard computer to
initiate several two-hour cold firings starting at apogee on orbit 297 (and
for the following three orbits).
AMSAT-DL reports the AO-40 team was very happy with the successful
results of the ATOS (Arcjet Thruster on OSCAR Satellite) system so far,
as was Robin Haighton, VE3FRH, who added; "thanks Peter, for the
good news. I am sure that all members of AMSAT are delighted by the
progress being made. Once more my congratulations to you and the
controllers."
Stay tuned to ANS, the official source of AO-40 information.

NEW PACKET SYSTEM READY FOR ALPHA
AMSAT NEWS SERVICE BULLETIN 175.02 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 24, 2001
TO ALL RADIO AMATEURS
BID: $ANS-175.02
AMSAT's Frank Bauer, KA3HDO, tells ANS that the ARISS-US team
recently delivered a new packet module to NASA. This new packet
module is expected to correct several of the problems that have been
observed with the current ARISS packet system.
The new equipment is currently scheduled to go through a bench review
inspection. If successful, the manifest calls for the module to be flown on
Mission STS-105, planned for launch in early August 2001.
Expedition-3 astronaut Frank Culbertson, KD5OPQ, is planning to make
the packet module change-out early in his ISS tour of duty. The current
packet module will stay on Alpha where it will serve as a power supply
for the 70-cm station that will be installed in the Service Module later this
year.
Some of the features of the new ARISS packet module include:
* All pertinent parameters are embedded in the PROM, so the packet
module should be fully functional even with a dead battery
* The new Russian callsign (RS0ISS) has been installed in the module.
The Personal Mailbox System (PMS) uses the callsign RS0ISS-1
* A 1 megabyte memory for adequate PMS data storage
* 8-bit capability to support Russian Cyrillic typesets
* A one-minute timeout disconnect from the PMS if no pertinent packets
are heard
ANS thanks the following individuals from ARISS-US who worked
hard to make get this module ready for flight on the STS-105 mission:

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 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
TEPR states on AO-27 were reset on March 24, 2001 as follows:

Launched: September 26, 2000 aboard a converted Soviet ballistic
missile from the Baikonur Cosmodrome. Status: Operational at
38k4-baud FSK
Paul, KB2SHU, reports he was pleasantly surprised recently to see
TiungSat-1 working again over North America. His system logged the
satellite for the first time in many months.
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.

Mode-S Beacon 2401.500 MHz
Launched: March 1, 1984 by a Delta-Thor rocket from Vandenberg Air
Force Base in California. Status: Operational
Clive, G3CWV, reported to ANS that it has been an uneventful time for
OSCAR-11 during the period of May 15-June 9, 2001.
Battery voltage observed during daylight passes has continued to
decrease. The average value observed was 13.3 volts with a range of
13.1 to 13.5 volts. The internal temperatures have continued to
decrease, now -0.2 and -1.6 Celsius for battery and telemetry electronics
respectively.
The magnetometer calibrations have steadily changed during the many
years in orbit. Although the changes are small and are not noticeable on
a plot of individual channels, they do have a considerable effect when
the total magnetic field is calculated. The spin period has also varied,
now between 300 and 344 seconds, with the attitude control working
normally.
The mode-S beacon is active, transmitting an unmodulated carrier. This
beacon is a useful test source for those testing mode-S converters for
AO-40.
Users of OSCAR-11 should note that the hardware generated time in the
ASCII telemetry is now 15.5 minutes ahead of UTC, and the date is three
days advanced. Unfortunately these errors cannot be corrected.
The operating schedule is as follows:
ASCII status (210 seconds)

Launched: July 10, 1998 by a Zenit rocket from the Baikonur
Cosmodrome. Status: Non-operational, no data downlinked
since December 18, 2000.
Chris G7UPN, (UoSAT operations manager) reports the
following to ANS:
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.
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:

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.

SUNSAT SO-35
Mode J Uplink: 145.825 MHz FM
Mode J Downlink: 436.250 MHz FM
Mode B Uplink: 436.291 MHz FM
Mode B Downlink: 145.825 MHz FM
Launched: February 23, 1999 by a Delta II rocket from Vandenberg Air
Force Base in California. Status: Non-operational
The SunSat team released the following statement, dated
February 1, 2001:
We regret to announce that the last communication with SunSat from our
ground station at the Electronic Systems Laboratory at Stellenbosch
University took place recently. We are certain, after having performed
several tests since the last contact, that an irreversible, physical failure
has occurred on the satellite. It is therefore unlikely that we will have
any further contact with SunSat, apart from the occasional visual sighting
by telescope!
When it was operational the SunSat package included 1200 and 9600
baud digital store-and-forward capability and a voice 'parrot' repeater
system in addition to Mode B/J operation with two VHF and two UHF
transmit-receive systems.

RADIO SPORT 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
Status: non-operational (last operational in mode-T)
RS-12 was re-activated in January 2001. Prior to this switch RS-13 was
operational (mode T), but was apparently turned off following the recent
RS-12 switch.

KITSAT KO-23
Uplink 145.900 MHz FM (9600-baud FSK)
Downlink 435.170 MHz FM
Broadcast Callsign HLO1-11
BBS HLO1-12
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, reported 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/was underway.

TECHSAT-1B GO-32
Downlink 435.225 MHz using HDLC telemetry
Launched: July 10, 1998 by a Russian Zenit rocket from the Baikonur
Cosmodrome. 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.

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.
The Naval Postgraduate School developed PanSat. 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).

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.
