TELSTAR 5 IN ORBIT
TECH-NOTE: 05/27/97
Telstar 5, a new satellite built by Space Systems/Loral, was launched on a
Russian Proton rocket from the Baikonur Cosmodrome in Kazakhstan, Saturday,
May 24, 1997. The satellite carries 24 36MHz C-band transponders, 24 27
MHz Ku-band transponders and four 54 MHz Ku-band transponders. At Ku-band,
the power amplifiers are 100 watt TWTAs (traveling wave tube amplifiers)
and at C-band they are 20 watt SSPAs (solid state power amplifiers). While
the transponder configuration is similar to that of Telstar 4 (formerly
Telstar 402R), transponder power has been increased.
The satellite occupies a geosynchronous orbital position at 97 degrees West
Longitude, the former location of Telstar 401 which was lost from service
earlier this year. Telstar 302 which was moved into this position shortly
after the failure of Telstar 401, has been shut down and allowed to drift
to 97.1 degrees West Longitude to make room for Telstar 5.
Loral Skynet has replaced AT&T Skynet as the management company for the
Telstar geosynchronous satellites. Occasional bookings may be ordered from
the Loral Skynet service center in Hawley at (800) 242-2422. Loral Skynet
will begin taking orders for Telstar 5 beginning June 1, 1997 for service
which is scheduled to begin on July 1, 1997. Booking windows for Telstar 5
are:

Four additional highpower satellites, Telstar 6,7,8 & 9, are in the
planning or construction stages. Telstar 6 is expected to be launched in
late 1998 and Telstar 7 is expected to be launched in early 1999. |
