AMSAT NEWS SERVICE BULLETIN 215.S2 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 03, 2003
TO ALL RADIO AMATEURS
BID: $ANS-215.S2
UO-11 OSCAR-11
Downlink: 145.826 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: Semi-operational.
OSCAR-11 now operates in a default mode, controlled by the watch-dog
timer. The satellite transmits continuous ASCII telemetry for about
8 - 9 days on 145.826 MHz., followed by about 10 - 12 days of
silence. These times appear to be somewhat variable, and this regular
sequence might be interrupted by ground control.
The mode-S beacon on 2401.5 MHz transmits continuously.
At the present time, ground control are unable to command the
satellite, due to low temperatures affecting the command decoder.
They will attempt to command the satellite when the command decoder
temperature has risen to 15C.
A Windows Soundcard program for displaying and capturing OSCAR-11 data
is now available. This is MIXW2, a general purpose Amateur Radio data
communication program written by Nick Fedoseev UT2UZ.
You can download the program from www.mixw.net
You need the latest version 2.07. Unfortunately the documentation for
this version of MIXW2 does not cover the OSCAR-11 application. However
there is a package of instructions and examples on G3CWV's website (URL
below).

UO-22 UOSAT
Uplink: 145.900 FM 9600-baud FSK
Downlink: 435.120 MHz FM
Broadcast Callsign: UOSAT5-11
BBS: UOSAT5-12
Launched: July 17, 1991 by an Ariane launcher from Kourou,
French Guiana. Status: Operational.
UO-22 has been reported as silent.
On April 26, 2003 Chris Jackson, G7UPN reported:
We're still assessing the situation, but as I posted late last year,
when UO-22 entered eclipses again (last week) it was unlikely that
the battery would supply sufficient power to operate the spacecraft.
This is indeed the case, and the spacecraft is therefore now unusable
at this time.
On May 10, 2003 Chris reports:
Possibly it is permanent. It is currently experiencing eclipses and can
not support operations. I haven't run the analyses yet to see when this
season ends, and for how long it will be in permanent sunlight again
next time around, but it may be possible to revive it for a while at least.

IO-26 ITAMSAT
Uplink: 145.875 145.900 145.925 145.950 MHz
FM (1200-baud)
Downlink: 435.812 MHz SSB
Broadcast Callsign: ITMSAT-11
BBS: ITMSAT-12
Launched: September 26, 1993 by an Ariane launcher from Kourou,
French Guiana. Status: Semi-operational, the digipeater function is on
and open for APRS users.
On November 18, 2002 Alberto, IK2BD reported:
The current configuration of IO-26 allows only limited telemetry in MBL (safe)
mode. To enable full telemetry and digipeating, we must re-load the full IHT
high level software suite. This was delayed several times, but we plan to do
that in the near future. When the IHT code is running, the bulletin will
announce that.

IO-26 information]

NO-44 PCSAT
Uplink/downlink: 145.827 MHz 1200 baud AX.25 AFSK via W3ADO-1
Aux/Uplink: 435.250 MHz 9600 baud via PCSAT-2 (off)
APRS Downlink: 144.390 MHz (Region 2)
Launched: September 30, 2001 aboard an Athena-1 rocket from the
Kodiak, Alaska launch complex. Status: Operational.
PCSat is a 1200-baud APRS digipeater designed for use by
stations using hand-held or mobile transceivers. Downlinks feed a
central web site < http://pcsat.aprs.org >. The APRS-equipped
PCSat was built by midshipmen from the U.S. Naval Academy
under the guidance of Bob Bruninga, WB4APR.
From Bob, WB4APR:
=====
PCsat permanent QRT at hand.
We were hoping she would make it to the 17-31 July full sun period, but
the last packet captured was 7 days prior, on about the 10th of July.
My guess is that one or more of the NICAD cell's finally shorted, reducing
the voltage below our low-voltage cut-off circuit which was designed to
protect one side from a failed battery on the other.... and in the end
game, to shut it up for good...
We are half way through this full sun period, so I havent given up yet,
but the writing is on the wall... The last packet on 10 July represents
about 21 months 10 days or so and about 4000 deep cycles on the
batteries...(9000 cycles total).

MO-46 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 at
38k4-baud FSK.
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.

AO-49 AATiS OSCAR-49 (SAFIR-M)
Uplink 435.275 1200-baud AFSK
Downlink 145.825 9600-baud FSK
(optional voice message)
Broadcast callsign: DP0AIS
Launched: December 20, 2002 aboard a converted Soviet ballistic
missile from the Baikonur Cosmodrome. Status: Operational.
AO-49 (SAFIR-M) is a German amateur radio payload onboard the
small German scientific satellite "RUBIN-2".
AO-49 was built by the German amateur radio association
"AATiS e.V." (German acronym for "Arbeitskreis Amateurfunk
und Telekommunikation in der Schule", which means: 'working group
for amateur radio and telecommunications in schools').
AO-49 is designed as a "store and broadcast" system for APRS
based messages, dedicated for the use of schools in combination
with the existing WX-Net and planned buoy experiments in Germany.
No transmissions detected since the 1st of February 2003!
It appears AO-49 is not properly aligned to illuminate the solar
panels. This should end soon. Due to its orbit, AO-49 will be in a
phase without eclipses until 13Feb03.
Martin DG8UAU has written a small software program "SAFIR-M Decoder"
to allow decoding of the received DATA0 frames. It is available at:
http://amend.gmxhome.de in the section Aktuelles.
Details on AO-49 (SAFIR-M) can be found at:
