The satellite is a user-funded project with the Ministry of Earth Science (MoES), configured around ISRO’s I-2k bus platform with a lift-off mass of 2275 kg. Indian Industries have significantly contributed in the making of the satellite.
According to sources, the space agency is said to be aiming for a mid-February launch.
“INSAT-3DS, is an exclusive meteorological satellite realised by ISRO with the primary objective to provide continuity of services to the existing in-orbit INSAT-3D and 3DR satellites and significantly enhancing the capabilities of the INSAT system,” ISRO said.
It was flagged off to SDSC-SHAR launch port in Andhra Pradesh on January 25, it said, adding that Pre-Shipment Review (PSR) was also held with the participation of members from the user community.
According to ISRO, the satellite is designed for enhanced meteorological observations and monitoring of land and ocean surfaces for weather forecasting and disaster warning, with state-of-the-art payloads: 6 channel Imager & 19 channel Sounder meteorology payloads, communication payloads viz., The Data Relay Transponder (DRT) and Satellite aided Search and Rescue (SAS&R) transponder. The DRT instrument receives meteorological, hydrological and oceanographic data from automatic Data Collection Platforms or Automatic Weather Stations (AWS) and augments the weather forecasting capabilities.
SAS&R transponder is incorporated in the satellite to relay a distress signal or alert detection from the beacon transmitters for search and rescue services with global receive coverage.
