From Naughty to Obedient: ISRO Launches INSAT-3DS Satellite atop GSLV Rocket

On Saturday, the INSAT-3DS meteorological satellite embarked on its journey from Sriharikota, Andhra Pradesh, aboard a Geosynchronous Launch Vehicle (GSLV) rocket in its 16th mission. Successfully reaching its intended orbit, the GSLV rocket deployed the INSAT-3DS satellite, marking a significant achievement for the Indian Space Research Organization (ISRO). Chairman S Somanath extended his congratulations to the team, confirming the successful deployment of solar panels.

The primary objective of the INSAT-3DS mission is to ensure the continuity of services provided by the current operational INSAT-3D and INSAT-3DR satellites. It aims to enhance meteorological observations, monitor land and ocean surfaces for weather forecasting and disaster warning, and provide Satellite Aided Search and Rescue Services.

The payloads onboard ISRO’s INSAT-3DS satellite include:

1. Imager and Sounder: Featuring a 6-channel Imager and a 19-channel Sounder, dedicated to advanced meteorological observations.

2. Communication Payloads: Crucial communication payloads, including the Data Relay Transponder (DRT), facilitate seamless data transmission.

3. Data Collection: The DRT receives data from automatic Data Collection Platforms and Automatic Weather Stations, bolstering weather forecasting capabilities.

4. SAS&R Transponder: The SAS&R transponder plays a pivotal role in relaying distress signals and alert detections from beacon transmitters, contributing to global search and rescue services.

Regarding ISRO’s next mission, Chairman Somanath affirmed that the joint venture with NASA, named NISAR, is proceeding as scheduled. NISAR, a collaborative Earth-observing mission, leverages two radars optimized to observe a broader spectrum of changes, significantly enhancing observational capabilities beyond those achievable with a single radar.
