The Indian National Satellite System-INSAT-I, currently under implementation for operationalisation during 1981, is a multipurpose satellite system for domestic telecommunications and meteorology with capability for nation-wide direct-Tv broadcasting to the rural communities of India. The space-segment of the system will initially comprise of two multi-purpose satellites in geo-stationary orbit, each of which combine capabilities for long-distance telephony, data and TV transmissions, continuous meteorological earth observations in the Visible and Infra Red bands, relay of meteorological data from unattended data relay platforms, disaster warning, radio programme distribution, and direct TV broadcasting to community TV sets. The ground-segment is also designed to be multipurpose in part. INSAT-I thus represents a unique, cost-effective concept. This paper presents an overview of the system.
