Detailed explanation-1: -INSAT-3D and INSAT-3DR satellite data are used in forecasting / monitoring weather.
Detailed explanation-2: -The fact that geosynchronous allow satellites to maintain a set position over the globe makes them particularly useful for weather monitoring, allowing scientists to continuously observe a specific area to see how weather trends emerge and develop.
Detailed explanation-3: -A geostationary satellite has a radius of orbit 42, 400 km and at a height above the earth’s surface 36, 000 km. One satellite could cover 42% of the area of the whole globe and we would need at least 3 of them to cover completely.
Detailed explanation-4: -Due to its fixed position, the geostationary orbit can document and record significant Earth from its constant position. A geostationary satellite will always seem to be stationary to Earth.
Detailed explanation-5: -A single geostationary satellite is on a line of sight with about 40 percent of the earth’s surface. Three such satellites, each separated by 120 degrees of longitude, can provide coverage of the entire planet, with the exception of small circular regions centered at the north and south geographic poles.
