As India gears up for the launch of the INSAT-3DS meteorological satellite aboard the GSLV-F14 rocket, excitement crackles through the nation. Scheduled for liftoff from Satish Dhawan Space Centre on Saturday at 5.35 pm, this isn’t just a fiery spectacle; it’s a pivotal step towards strengthening India’s weather forecasting and disaster management capabilities. Let’s delve deeper into the GSLV-F14/INSAT-3DS Mission and explore its transformative potential.

What exactly is ISRO aiming to achieve with this mission?

According to ISRO, the objective of Saturday’s mission GSLV-F14/INSAT-3DS would provide continuity of services to existing operational INSAT-3D (launched in 2013) and INSAT-3DR (September 2016) for enhanced meteorological observations, monitoring of land and ocean surfaces for weather forecasting and disaster warning, as well as to provide Satellite aided Research and Rescue services (SAR) among others.Sharpen forecasting prowess
The satellite weighing 2,274 kg, once operational, would serve various departments under the Ministry of Earth Sciences, the Indian Meteorological Department (IMD), National Institute of Ocean Technology (NIOT), National Centre for Medium-Range Weather Forecasting, and Indian National Centre for Ocean Information Services.

Empower disaster management
The 51.7 metre tall rocket will be carrying imager payloads, sounder payloads, data relay transponder and Satellite Aided Search and Rescue transponders, which would be used to study cloud properties, fog, rainfall, snow cover, snow depth, fire, smoke, land and ocean, among other uses.

The imager and sounder payloads incorporated in the latest mission are similar to the payloads carried by INSAT-3D and INSAT-3DR, with significant improvements in radiometric performances, ISRO said.

Who funded this mission?
The INSAT-3DS satellite is a follow-on mission of the third generation meteorological satellite to be placed in a geostationary orbit, and it is fully funded by the Ministry of Earth Sciences.

This is the second mission for the Bengaluru headquartered space agency in 2024 after the successful launch of PSLV-C58/EXPOSAT mission on January 1.

Post launch manoeuvres
About 20 minutes after liftoff, scientists aim to deploy the INSAT-3DS satellite into a Geoynchronous Transfer Orbit (GTO). Later, they will undertake orbit-raising manoeuvres to place the satellite into a Geo-stationary Orbit, which is expected to happen in a couple of days.
