Space Systems/Loral
(SS/L), a subsidiary of Loral Space & Communications, has
been awarded a contract to design and build APSTAR-V, a high-powered,
C/Ku-band satellite for APT Satellite Company Ltd. (APT Satellite),
Hong Kong.

APSTAR-V will replace the aging APSTAR-I satellite at its
geostationary orbital position of 138 degrees East longitude. It will
provide Ku-band voice, video and data services to China, Hawaii, and
East Asia, and C-band services to other parts of the Asia-Pacific
region, including Australia and Hawaii. The new satellite will also be
used to provide space-based Internet backbone services for the main
cities of Asia to and from the U.S. through Hawaii.

Under the new contract, which requires SS/L’s receipt of the
necessary U.S. government export licenses, SS/L will also provide
customary pre- and post-launch support services. APSTAR-V is scheduled
for launch in early 2003, with APT procuring the launch vehicle and
insurance. The spacecraft is expected to begin service in the spring
of 2003.

The Satellite

APSTAR-V is a high-powered C/Ku-band hybrid satellite based on
SS/L’s 1300 platform, similar to APSTAR-IIR, which is currently on
orbit serving the Asia-Pacific region. APSTAR-V will have total
beginning-of-life power of 10.6 kW with a separated mass of
approximately 4,845 kg, and 9.5 kW of end-of-life power. The new
spacecraft will operate a total of 54 transponders, 38 in the C band
at 60 watts, and 16 in the Ku band at 141 watts.

Based on SS/L’s space-proven 1300 platform, APSTAR-V is designed
for a mission life of 13 years. The 1300, which has an excellent
record of reliable operation, is designed to achieve a long useful
orbital life, excellent station-keeping, and orbital stability by
using bipropellant propulsion and momentum-bias systems. A system of
high efficiency solar arrays and lightweight batteries provides
uninterrupted electrical power. In all, SS/L satellites have amassed a
total of nearly 800 years on orbit.
