SPUTNIK 40 YEARS

HR AMSAT NEWS SERVICE BULLETIN 222.01 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 10, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-222.01

On the 20th February 1997, an agreement was signed between Russia and
France to commemorate the 40th anniversary of the launch of the first
artificial satellite of the Earth: Sputnik-1.  Two groups of high school
students will cooperate to build a functional scale model (1:3) of the
original Sputnik satellite.  Students from NALTCHIK in Russia will build
the body of the satellite, and students from Reydellet School in
LA REUNION will build the radio transmitter that will "beep-beep" from
space after launch from the MIR space station on the 4th October 1997.
This is an exceptional educational event which deserves full attention
and which should be used to raise the worlds awareness that a truly new
era in the evolution of Mankind had been opened 40 years ago.

Aero-Club de France and the Russian Federation of Astronautics will help
raise funds for the transportation of the 4 kg model to MIR and for the
launch during an EVA. A world-wide fund-raising drive "40 sponsors
for the 40 years of Sputnik" with 40 shares tagged at US $ 6,000 each
is under way. Further information is available in the WWW:

SPUTNIK 40 YEARS FAQ

.
1. The transmitter will be activated in October during an EVA
    MIR. The scale model of the original Sputnik satellite should
    have a life time will be between 1 and 2 months.

2. The scale model of Sputnik will be launched by hand so it will
   not be very far from MIR.
   But MIR is  frequently doing orbital adjustments.  So it is
   unknown how long the orbital elements will be the same as MIR.
   This will be a good exercise for students to try to compute
   the orbital elements following the doppler.

3. The transmit power is between 100 and 200 mW.
   The antenna polarization is circular, and will be right or left
   depending on  how ones orientation is to the satellite.
   The scale model of Sputnik has no attitude stabilization.
   The modulation is FM and the BF [audio] signal is around 1.3 KHz
   and it will vary with the temperature.  Another good exercise for
   students is to measure the audio frequency and see the
   what scale model of Sputnik's  temperature is.
   The RF signal sounds like a beep-beep as it is ON/OFF with a
   duty cycle of 5.  The full cycle is around 4s.

   You can listen the beep-beep in FM position or SSB position.
   The sound is really nicer in SSB position, but if you want to
   measure the audio frequency you should be in FM.  It will not
   be an easy exercise because it is a burst and the dynamic of
   frequency variation is low.

4. Equipment needed to receive the signal.
   In the best case to be able to receive  the scale model of Sputnik is
   on a handheld receiver with an antenna gain of 0 dB, but as they will
   not know  the satellite attitude in space it will be better to have a
   yagi with 10 dB gain (around 9 elements).

5. Frequency for the scale model of Sputnik.
   Not fully finalized but between 145,810 and 145,850 MHz.

HOUSTON AMSAT NET UPDATE

SILVER SPRING, MD, AUGUST 10, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-222.03

The Houston AMSAT Net is reaching another milestone in its history.
In the next few weeks, they will be able to bring their net live on the
world wide web via a live stream with Real Audio. Scott at North American
Internet had been digitizing the Houston AMSAT net from the satellite
and he will no longer be able to do it. Last night was the first time

Scott will have a live stream available for the Houston AMSAT Net at the
beginning of September. What this means to you. You can now hear our net
live as it is happening anywhere in the world via Real Audio. You can
participate in the Net by calling in and checking in or by asking a
question which will be answered live. Or you can check in via email or
use the IRC where a group of Hams chat during the net.

Now, even if you do not have a KU-Band satellite dish/receiver, you can
carry our net over your local repeaters with the Real Audio feed.
The other important feature of this is that during the week if something
hot related to AMSAT hits the news, we can update our Real Audio by adding
to the end of the net. What Bruce Paige, KK5DO,  plans on doing for this is
making a note on his web page that minutes 51:01.3 to 53:03.4 (an example)
were added on August 9. Such things as the oxygen generator aboard the MIR
shutting down would be of interest and could be added to the tail end of
the net.

The Houston AMSAT Net can also carry their net over the 50 minutes
allocated on the satellite feed. This means if there is an especially
heavy news week, they can continue the net locally and continue the feed
over the internet.

BID: $ANS-222.04

It is with great sadness that AMSAT has to report that Elgar Trehame, VK5ED,
passed away on August 6th  after a number of weeks of ill health.
Elgar was very active on AO-10 and AO-13 and was hoping to have the
opportunity to use Phase-3D but sadly that was not to be.
Elgar was a friend and mentor to many amateurs around the world .  His
cheerful patter and often pointed questions will be sorely missed....

Many may not know that Elgar was often called upon to support the
Command Station activities on AO-13 and spent many hours collecting 400
baud PSK telemetry in that role and AMSAT had hoped that he would be able
to do the same with Phase-3D particularly in those early days after the
launch.

Any messages of sympathy sent his wife Janette can sent mail direct to his
home address which is correct in the callbook..

ONE LESS LITTLE LEO

HR AMSAT NEWS SERVICE BULLETIN 222.05 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 10, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-222.05

The Little LEO industry that has been seeking access to spectrum
below 1 GHz, including amateur bands, is about to have one less
player. On July 14, CTA Incorporated of Rockville, Maryland, and
Orbital Sciences Corporation of Dulles, Virginia, announced an
agreement for Orbital to purchase CTA's satellite manufacturing and
communications service business units. The deal is expected to close
in August.

Orbital is already in a joint venture with Teleglobe to provide
Little LEO services through Orbital Communications Corp. (ORBCOMM).
ORBCOMM's system is already licensed and is operational on a limited
basis. Uplinks are 2400 bps FSK in the 148-149.9 MHz band and user
downlinks are 4800 bps FSK in the 137-138 MHz band, with beaconing in
the 400-401 MHz band. In its press release announcing the
acquisition, Orbital said that a CTA service it had purchased, called
GEMtrak, may be expanded to use the ORBCOMM network in the future.
GEMtrak is a system for tracking truck trailers and rail cars and
their cargoes.

ARRL Executive Vice President David Sumner, K1ZZ, noted that the
combining of CTA's satellite business with ORBCOMM's will reduce by
one the number of companies seeking Little LEO licenses. ''CTA was one
of the companies that sponsored the ill-conceived and controversial
'flexible allocation' proposal that we had to oppose earlier this
year,'' he said. ''ORBCOMM did not endorse the flexible allocation
concept.''

The Little LEO issue is on the agenda for the World
Radiocommunication Conference (WRC-97) to be held this fall. ARRL
Technical Relations Manager Paul Rinaldo, W4RI, is a member of the US
delegation. The US is now finalizing its proposals for the
conference. At this point, no US Little LEO proposal for WRC-97 would
affect ham radio.

modulation is about 20 dB below the carrier.  You should hear what sounds
like a carrier with lots of Doppler.  If you receive equipment is working
well you will hear the 'buzz' from the flags and an occasional change in
the sound of that modulation as a telemetry beacon is sent.  If it's
working really well and you run the received audio through a PSK demod then
a tracking notch filter (DSP) you will clearly hear the flags and
modulation. In the northern hemisphere there will be deep fades about
every 30 seconds due to the rotation of the satellite.  In the southern
hemisphere there will probably be some fades but not nearly as deep
because the antenna points down when below the equator.
