From Launchpad to Geosynchronous Orbit: The Mission Journey

The INSAT-3DS satellite, weighing in at a mighty 2,274 kg, will embark on its journey aboard a Geosynchronous Launch Vehicle (GSLV) rocket. After separation from the GSLV approximately 20 minutes post-launch, the satellite will be placed into a temporary Geosynchronous Transfer Orbit (GTO). Subsequent maneuvers in the following days will propel it into its designated Geostationary Orbit (GEO), where it will reside at a height of approximately 36,000 kilometers above the equator.

Unveiling the Eyes of INSAT-3DS: Capabilities and Objectives

The INSAT-3DS mission carries the vital responsibility of continuing and enhancing the meteorological observations currently provided by its predecessors, INSAT-3D and INSAT-3DR. Equipped with sophisticated imager payloads, sounder payloads, data relay transponders, and Satellite-aided Search and Rescue transponders, this technological marvel is designed to:

  • Monitor atmospheric and surface phenomena: Cloud properties, fog, rainfall, snow cover, wildfires, smoke, and land/ocean surface conditions will be under constant observation.
  • Deliver crucial data: Collected data will be instrumental for accurate weather forecasting and climate analysis, aiding various Indian institutions like the India Meteorological Department and the National Centre for Medium Range Weather Forecasting.
  • Support search and rescue efforts: The onboard Satellite-aided Search and Rescue transponders will play a vital role in locating individuals in distress on land or at sea.

With a projected mission life of 10 years, INSAT-3DS promises to be a cornerstone of India’s space-based weather observation system, fostering resilience against natural disasters and aiding sustainable development initiatives.
