Satellite INSAT-3DS on launch vehicle GSLV-F14, was successfully launched by the ISRO from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
INSAT-3DS will augment the country’s meteorological (weather, climate, and ocean related) services with the presently operational INSAT-3D and INSAT-3DR in-orbit satellites. The newly launched INSAT-3DS satellite aims to enhance the monitoring of Earth’s surface, atmosphere, oceans, and environment, elevate capabilities in data collection and dissemination and satellite-aided search and rescue services. The initiative will boost Bharat’s weather, climate, and ocean-related observations and services, expanding knowledge and better disaster mitigation and preparedness in the future.
The 51.7-meter (m) tall and 4 m wide Geosynchronous Satellite Launch Vehicle (GSLV)-F14 placed the INSAT-3DS satellite into a geosynchronous transfer orbit, then to a geosynchronous stationary orbit in space. INSAT-3DS is configured around ISRO’s well-proven I-2k bus platform with a lift-off mass of 2,275 kilograms.
It is equipped with state-of-the-art payloads: (i) an imager payload with a six-channel optical radiometer to generate images of the Earth and its environment; (ii) a 19-channel sounder payload to provide information on the atmosphere; communication payloads, namely (iii) a data relay transponder to receive meteorological, hydrological and oceanographic data from automatic data collection platforms, and (iv) a satellite aided search and rescue transponder that relays a distress signal or alert from beacon transmitters with global coverage. Indian Industries have significantly contributed to the making of the INSAT-3DS.
This will boost weather and climate prediction and forecasts, timely alerts and early warnings, and advisories for public and last mile users such as fisherfolk and farmers.
