To bolster meteorological observations and disaster management, the Indian Space Research Organization (ISRO) achieved yet another milestone with the successful deployment of the INSAT-3DS satellite. Lifted off aboard a Geosynchronous Launch Vehicle (GSLV) rocket from Sriharikota, Andhra Pradesh, on Saturday, the mission marked the 16th successful mission for GSLV.

Chairman of ISRO, S Somanath, lauded the efforts of the team, confirming the flawless deployment of the INSAT-3DS satellite into its intended orbit. Notably, the successful unfurling of solar panels was also confirmed, ensuring the satellite’s power supply for its operational phase.

The primary objectives of the INSAT-3DS mission revolve around advanced meteorological observations, land and ocean surface monitoring for weather forecasting and disaster warning, and providing crucial Satellite Aided Search and Rescue Services. The mission aims to continue and enhance the services offered by the operational INSAT-3D and INSAT-3DR satellites.

Among the payloads onboard the INSAT-3DS satellite are:

1. Imager and Sounder: Equipped with a 6-channel Imager and a 19-channel Sounder, the satellite enables advanced meteorological observations, providing essential insights into various atmospheric conditions.
2. Communication Payloads: Featuring vital communication payloads, including the Data Relay Transponder (DRT), the satellite enhances communication capabilities crucial for weather forecasting and disaster management.
3. Data Collection: The DRT facilitates the reception of data from automatic Data Collection Platforms and Automatic Weather Stations, contributing to improved weather forecasting abilities.
4. SAS&R Transponder: Playing a pivotal role in relaying distress signals and alert detections from beacon transmitters, the SAS&R transponder contributes significantly to global search and rescue services.

Looking ahead, ISRO’s next mission, as confirmed by Chairman Somanath, is the joint mission with the National Aeronautics and Space Administration (NASA) named NISAR. NISAR, a collaborative Earth-observing mission, will utilize two radars optimized for observing a broad spectrum of changes, thus enhancing observational capabilities crucial for understanding Earth’s dynamics and processes.
