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. *Insat-1A was abandoned in September 1983 when its attitude control propellant was exhausted* Auxiliary Information Launch Date and Time : 1982-04-10 06:47:00 Epoch Date and Time : 1982-04-11 Orbit Type : Geocentric Apogee(km) : 35784.
