INSAT-3DS, is an exclusive meteorological satellite realized 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
INSAT system is flagged off to SDSC-SHAR launch port on January 25, 2024 for the
launch onboard GSLV F14. The Satellite had successfully completed Satellite
Assembly, Integration & Testing activities at U R Rao Satellite Centre,
Bengaluru. Pre-Shipment Review (PSR) was held with the participation of members
from user community on January 25, 2024.
The satellite is a user funded project with Ministry of Earth Science (MoES),
configured around ISRO's well proven I-2k bus platform with a Lift-Off Mass of
2275 kg. Indian Industries have significantly contributed in the making of the
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 viz., 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
Data relay transponder (DRT) instrument, receives meteorological, hydrological
and oceanographic data from automatic Data Collection Platforms / Automatic
Weather Stations (AWS) and augments the weather forecasting capabilities.
Satellite aided Search and Rescue (SAS&R) transponder is incorporated in the
satellite to relay a distress signal / alert detection from the beacon
transmitters for search and rescue services with global receive coverage.
