When was the Indian National Satellite System (INSAT), a multipurpose satellite system for telecommunications, established?

The correct answer is 1983.

Key Points

• The Indian National Satellite System (INSAT) was established in 1983 by the Indian Space Research Organisation (ISRO).
• INSAT is a multipurpose satellite system, primarily used for telecommunications, broadcasting, meteorology, and disaster warning services.
• The launch of INSAT marked a significant milestone in India's space program, making it a key player in the satellite communication domain.
• INSAT-1B, launched in 1983, became the first operational satellite of the INSAT series and was a major success.
• The INSAT system has been instrumental in advancing India's capabilities in weather forecasting and rural communication.

Additional Information

• INSAT Series: The INSAT series includes multiple satellites launched over the years, such as INSAT-1A, INSAT-1B, INSAT-2 series, and INSAT-3 series, each with upgraded capabilities.
• Applications: INSAT satellites have supported a wide range of applications including television broadcasting, VHF communications, and search-and-rescue operations.
• Meteorological Contributions: INSAT has significantly enhanced India's meteorological observation capacity by providing real-time weather data and cyclone tracking.
• Geostationary Orbit: INSAT satellites are placed in geostationary orbit, allowing them to provide continuous coverage over a fixed geographic region.
• Current Status: The INSAT system has evolved into the GSAT (Geo-Stationary Satellite) series, further strengthening India's satellite communication and meteorological infrastructure.
