Communication

Communication Satellite provides the essential satellite based services to the nation, which comprises of Telecommunication,Television and Radio broadcasting, Meterorological imaging and weather forecasting, weather data collection and data dissemination, Disaster warning etc. For providing these services the space system has two segments viz. the space segment and the user ground segment. The space segment consists of the spacecraft at different orbital slots.
