Insat 3A carries also the usual Insat package of sensors in visual, infrared and water vapor bands to monitor clouds and storms. The spatial resolution at visual wavelengths is 2 km, and at infrared 1 km. The satellite also carries a separate transponder for the international search and rescue program.
