SB SAT @ AMSAT $ANS-008.01
PoSAT-1 BBS TO OPEN
HR AMSAT NEWS SERVICE BULLETIN 008.01 FROM AMSAT HQ
SILVER SPRING, MD JANUARY 8, 1993

PoSAT-1 Opens For Radio Amateur Use
As many of you may already know, PoSAT-1 was built at University of Surrey
and is owned by a Portuguese Industrial Consortium. It carries a commer-
cial and an Amateur Radio payload. The Amateur Service hasn't yet started
operation because of some doubts about the use of PoSAT-1 were brought up
because of the the possiblity of misuse of the Amateur Radio spectrum.
AMSAT-PO (the Portuguese AMSAT "branch") and others were very worried about
this situation, and after a few setbacks and many meetings, a protocol was
finally established between the PoSAT Industrial Consortium and AMSAT-PO on
6-DEC-93. The main concern of AMSAT-PO was always to protect the Amateur
bands and the Amateur code and practice.
Jose Carlos (CT1ERC) has provided the main points of that agreement which
are as follows:
* RAM memory allocated to the Amateur store-and-forward BBS: at least 6 MB
out of a total of 16 MB;
* The operating schedule (between the commercial and Amateur service) will
be valid for two years and may be re-negotiated every two years;
* The Amateur ground stations are allowed to download all the files related
to the technical and scientific experiments onboard, but by imposition of
the Consortium, the IMAGES TAKEN BY THE ONBOARD CCD CAMERAS WILL NOT BE
MADE AVAILABLE TO THE AMATEUR RADIO SERVICE!!!
In a meeting held recently between AMSAT-PO officials and the PoSAT
Consortium the schedule approved is as follows:
EVERY minute PoSAT will be 5 seconds in the commercial frequencies and
the remaining 55 seconds in the amateur frequencies. The Consortium
feels that they need at lest 5 seconds to download the images. The
telemetry will be downloaded in the amateur frequencies as well. This
schedule will be valid starting on 07-JAN-94.
Since the amateurs aren't allowed to download the image files from the
onboard cameras, there are the two experiments that will, however, be quite
interesting. The are the following:
1) The onboard GPS receiver: if everything goes as expected, the days of
difficult tracking are over. Just wait the AOS and the satellite will
tell you were it is and where to point your antennas, if you know your
QTH position.
2) The possibility of operation at 38.4 Kbps provided through the DSP
system, which is will allow the amateurs to develope the necessary RF
and digital techniques to go beyond 9600 baud. Imagine receiving
about 100 Kbytes file in just 5 seconds!
PoSAT-1 will benefit mostly the amateurs that have 9600 baud operational
capability and since there are only two of 9600 baud capable stations at
the present time in Portugal operating regularly using these birds, your
suggestions and comments would be most appreciated and might help AMSAT-PO
in their contacts and negotiations with the PoSAT Consortium through
AMSAT-PO.
The following are the PoSAT-1 radio amateur frequencies:
PoSat-1 Transponder Frequencies
UPLINK 145.975 MHz 145.925 MHz (Secondary)
DONWLINK 435.075 MHz 435.050 MHz (Secondary)

MIR GETS A NEW CREW

New Cosmonauts To Begin Stay on MIR
Today, 08-JAN-94, a Soyuz TM-18 spacecraft was launched from Baikonur at
10:08 UTC with three cosmonauts aboard. The new cosmonauts are Victor
Afanassiev (U9MIR), Yuri Usachov (R3MIR), and Valery Poliakov (U3MIR).
The TM-18 spacecraft is scheduled to dock with the MIR space station on
10-JAN-94. The cosmonauts that are currently aboard MIR,Vassili Tsybliev
and Alexander Serebrov (R0MIR), will return to earth on 14-JAN-94.
What is interesting to note about U3MIR is that he will attempt to break
Musa Manarov record for remaining in space. U3MIR is a medical doctor and
will remain aboard MIR until April '95.
The new MIR QSL Manager is Serge Samburov (RV3DR). He has held that
position since January '93. To receive a QSL confirming your MIR contact,
send your QSL cards to his postal address of: P.O.BOX 73, Kaliningrad-10
City, Moscow Area, 141070, RUSSIA. Also, you can send your inquiries to
the following packet radio address: RV3DR#R#MIR or RV3DR@RK3KP.#MSK.RUS.EU.

STS-60 SAREX MISSION INFO

SILVER SPRING, MD JANUARY 8, 1993

BID: $ANS-008.03
Next SAREX Mission: STS-60
The STS-60 flight of the Space Shuttle Discovery represents the next
Shuttle Amateur Radio Experiment (SAREX) mission. STS-60 is
currently scheduled for launch on February 3, 1994 at 12:10 UTC. The
primary payloads on-board STS-60 are the Wake Shield Facility and the
second flight of the Spacehab, a pressurized module installed in the
forward section of the Orbiter. The Spacehab science objectives are
primarily micro-gravity oriented with emphasis on materials and life
science.
The flight of STS-60 represents an historic first---the first joint
U.S.-Russian Space Shuttle flight. This will be the first of several
joint missions planned in preparation for the development of the
international Space Station. Cosmonaut Sergei Krikalev, U5MIR, was
chosen to be the first Russian to fly on the U.S. Space Shuttle.
During the 8 day flight, Cosmonaut Krikalev will support the science
operations on the Space Shuttle as Mission Specialist 4.
The SAREX operations on this flight include voice and packet.
Preliminary discussions between the astronauts and the SAREX working
group indicate that the Shuttle crew will be extremely busy with the
numerous payloads on this flight. This information is being provided
so the amateur community is aware that voice operations might be rare
on this flight. Packet radio operations are expected when the crew
is not engaged in voice operations. Please remember that this is a
preflight prediction. The astronauts and the SAREX working group
cannot guarantee this prediction. The following information sheet
gives more details on SAREX operations for STS-60.

Note: SA stands for "Sun Angle"
Unfortunately, because AO-13's perigee height has decreased from 1500 KM to
420 KM, G3RUH is unsure about whether AO-13 will still be in orbit by the
end of '95 and into early '96. But if AO-13 has not re-entered into the
earth's atmosphere, the above Bahn longitiude and latitude values will be
the planned values.
