What are the payloads of INSAT-3DS?
Equipped with cutting-edge technology, INSAT-3DS will feature a 6 channel Imager and a 19 channel Sounder for meteorological purposes, alongside communication payloads including the Data Relay Transponder (DRT) and the Satellite-aided Search and Rescue (SAS&R) transponder.
The DRT is designed to collect and transmit meteorological, hydrological, and oceanographic data from Data Collection Platforms and Automatic Weather Stations (AWS), thus augmenting weather forecasting accuracy.
The SAS&R transponder will play a critical role in global search and rescue operations by relaying distress signals and alert detections from beacon transmitters, ensuring comprehensive receive coverage worldwide.
