The full form of INSAT is Indian National Satellite System. It is a series of multi-purpose geostationary satellites launched by the Indian Space Research Organisation (ISRO) for telecommunications, meteorology, and search and rescue operations.
The INSAT system was first launched in 1983 with INSAT-1B, and since then, several more satellites have been added to the system. These satellites are placed in geostationary orbit, which means they remain at a fixed point in the sky as seen from the Earth. This allows them to provide continuous coverage of a specific region.
The INSAT system is used for a variety of applications including television broadcasting, meteorological data collection and dissemination, telecommunication services such as telephone and fax, and search and rescue operations. The meteorological data collected by the INSAT satellites is used for weather forecasting and also to provide early warning of severe weather conditions such as cyclones.
The INSAT system also plays an important role in the country’s disaster management efforts. The satellites are equipped with search and rescue transponders that can be activated in case of a disaster to assist in locating survivors and providing aid.
In recent years, ISRO has developed advanced INSAT satellites such as INSAT-3D and INSAT-3DR, which are equipped with advanced imaging and atmospheric sounding capabilities for improved meteorological forecasting. The organization also plans to launch more advanced INSAT satellites in the future, such as INSAT-4, which will provide improved telecommunications and meteorological services.
In summary, INSAT is a series of multi-purpose geostationary satellites launched by the Indian Space Research Organisation (ISRO) for telecommunications, meteorology, and search and rescue operations. It plays an important role in the country’s disaster management efforts and have advanced capabilities such as INSAT-3D and INSAT-3DR for improved meteorological forecasting.
