Satellite and Bandwidth

INSAT - 4A is an exclusive communication satellite intended for providing high quality television, telecommunication, broadcasting services and is the first satellite to be launched in the INSAT-4 series. Weighing about 3120 kg at the lift-off, INSAT-4A carries 24 high power transponders - 12 operating in the Ku-band frequency and 12 in normal C-band. This satellite is launched during May-June, 2005 by Ariane-V Launch Vehicle from French Guiana. INSAT-4A is located at 83* E Longitude in the Geostationary orbit.

AsiaSat 5, a 8,289-pound [3,760-kg] broadcasting and networking satellite for Asia, is equipped with 26 C-band and 14 Ku-band transponders, with an operational life of 15 years. The spacecraft is operated by Hong Kong-based Asia Satellite Telecommunications Co. Ltd. AsiaSat 5's C-band footprint covers more than 53 countries spanning from Russia to New Zealand and from Japan to the Middle East and parts of Africa. This new satellite also offers two high-power fixed Ku-band beams over East Asia and South Asia, and a steerable beam that will cover anywhere within AsiaSat 5's geographic coverage.
