Spacecraft Brief Description
The Insat-1 satellite program incorporated two three-axis stabilized
spacecraft in geostationary orbit (Insat-1A at 74 degrees E and
Insat-1B at 94 degrees E) with a host ... of ground stations throughout
India. The Insat-1A satellite, built by the Ford Aerospace and
Communications Corporation, was designed to provide combined
telecommunications, direct TV broadcast, and meteorological service to
India's civilian community over a 7-year-in-orbit lifespan. The
telecommunications package provided two-way, long distance telephone
circuits and direct radio and TV broadcasting to the remotest areas of
India. The meteorology package was composed of a scanning
very-high-resolution, two-channel radiometer (VHRR) to provide
full-frame, full-earth coverage every 30 minutes. The visual channel
(0.55-0.75 micrometer) had a 2.75-km resolution while the IR channel
(10.5-12.5 micrometers) had an 11-km resolution. Using the Insat TV
capability, early warnings of impending disasters (i.e., floods,
storms, etc.) could directly reach the civilian population, even in
remote areas. The Insat-1A also had a data channel for relaying
meteorological, hydrological, and oceanographic data from unattended
land-based or ocean-based data collection and transmission platforms.
