<P style="MARGIN: 0px 15px 15px 0px">Syncom 3 was the first geostationary
satellite. (The earlier geosynchronous Syncom 2 had an orbit inclined to the
equator.) It was an experimental geosynchronous communications satellite placed
over the equator at 180 degrees longitude in the Pacific Ocean. The satellite
provided live television coverage of the 1964 Olympic games in Tokyo, Japan and
conducted various communications tests. Operations were turned over to the
Department of Defense on 1 January 1965, Syncom 3 was to prove useful in the
DoD's Vietnam communications.</P>

Profile</H4>
<P style="MARGIN: 0px 15px 15px 0px">Syncom 3 was launched from Cape Kennedy on
19 August 1964 and injected into an elliptical orbit inclined 16 degrees to the
equator following a third stage yaw maneuver. The apogee motor was fired to
remove most of the remaining inclination and to provide a circular
near-synchronous orbit of 35,670 km x 35,908 km. The spacecraft next carried out
a series of attitude and velocity maneuvers to align itself with the equator at
an inclination of 0.1 degrees and to slow its speed so it drifted west to the
planned location at 180 degrees longitude where its speed at altitude was
synchronized with the Earth. These maneuvers were completed by 23 September, and
Syncom 3 was used in a variety of communications tests, including the
transmission of the Olympics, transmissions between the Philippines, USNS
Kingsport, and Camp Roberts, California, and teletype transmissions to an
aircraft on the San Francisco-Honolulu route. Satellite operations were turned
over to the Department of Defense on 1 January 1965 and it was operated by the
DoD through 1966. It was turned off in April 1969.</P>

and Subsystems</H4>
<P style="MARGIN: 0px 15px 15px 0px">The Syncom satellites were 71 cm diameter,
39 cm high cylinders. The fully fueled mass of the spacecraft was 68 kg. The
nozzle of the solid propellant apogee motor (1000-lb-thrust designed to impart a
velocity increase of 1431 meters/sec) extended from the bottom of the cylinder
and a co-axial slotted array communications antenna from the top. The total
height including the nozzle was 64 cm. The radial exterior was covered with 3840
P-on-n silicon solar cells which provided direct power of 29 watts the 99
percent of the time the spacecraft was in sunlight. Nickle-cadmium rechargeable
batteries provided power when the spacecraft was in the Earth's shadow. No
active thermal control was required. Most of the central interior of the
spacecraft consisted of the tanks and combustion chamber for the apogee motor,
around this were arranged two hydrogen peroxide and two nitrogen tanks and the
electronics. Attitude and velocity control was provided by nitrogen jets to
align the spin axis and hydrogen peroxide jets to position the satellite. Each
system had two jets, one parallel and one perpendicular to the spin axis.</P>
<P style="MARGIN: 0px 15px 15px 0px">Syncom employed a redundant,
frequency-translation, active repeater communication system designed to handle
one two-way telephone or 16 one-way teletype channels. The dual transponders
utilized 2-watt traveling wave tubes. Selection of receiver and transmitter was
made by ground command. One receiver had a 13 megacycle bandwidth for TV
transmission, the other a 5 megacycle bandwidth. The receiving gain was 2 dB
through the slotted dipole antenna. Signals were received on two frequencies
near 7360 megacycles and retransmitted on 1815 megacycles. The slotted dipole
transmitting antenna radiated a pancake-shaped beam 25 degrees wide with its
plane perpendicular to the spacecraft spin axis. There were also four whip
antennas oriented normal to the spin axis for telemetry and
command.</P></DIV></DIV></DIV>

<P>Ah yes, the Conrac AV12e and AV82e with UHF too...</P>
<P>I used an AV12 to record ABC TV Olympics coverage</P>
<P>off-air for <EM>Australian </EM>ABC TV using a pair of HBC TR-</P>
<P>22s, in the evenings in Mt View, California, to then rush </P>
<P>the NTSC reels to SFO to 747 them to Sydney for </P>
<P>(presumably, conversion to PAL) broadcast down under. </P>
<P>Although I understand there was some coverage of the </P>
<P>1964 Tokyo games distributed via satellite, my memory </P>
<P>is that good international global geo-stationary satellite </P>
<P>services were not practically in place until almost the </P>
<P>80s. </P>
<P>The AV12E schematic looked a great deal like it was </P>
<P>lifted from an RCA television. Good for internally </P>
<P>distributing the news of the other stations in your town</P>
<P>to your newsroom. It was Clean, but had no special </P>
<P>circuits. So, of course, for the official Station Demods </P>
<P>[FCC], was were where the Tek 1450s ruled the roost.<BR></P>

<DIV>message got though fine David!</DIV>
<DIV> </DIV>
<DIV>Ah yes the Conrac tuner... we have one with
TUBES in it also!</DIV>
<DIV> </DIV>
<DIV>The picture is pretty good for going though all
that !</DIV>
<DIV> </DIV>
<DIV>Back to the Conrac tuner... were these used in stations
as 'monitoring devices' or to pick up signals for
retransmission or? </DIV>
<DIV> </DIV>
<DIV>many thanks Ed #</DIV>
