What is INSAT System? – INSAT System UPSC
The INSAT system is like a big group of special satellites that India launched into space. It started in 1983 with a satellite called INSAT-1B. These satellites are like high-tech helpers that changed a lot of things in India.
One big change is in TV and radio. The INSAT system helped spread television and modern phones to many places, even faraway areas and islands. Imagine, because of these satellites, people in remote areas could now enjoy TV and use better phone services.
The INSAT satellites also do something important for weather. They have tools on board to watch and study the weather, making it easier to predict what’s going to happen. One of the satellites, KALPANA-1, is like a weather expert in the group.
These satellites are watched over and controlled by special places called Master Control Facilities to make sure they work well. In simple terms, the INSAT system is like a team of space helpers that made TV and phones reach more places and helped us understand the weather better in India.
