It was flagged off to SDSC-SHAR launch port in Andhra Pradesh on January 25, it said, adding that Pre-Shipment Review (PSR) was also held with the participation of members from the user community.
 
According to ISRO, the satellite is designed for enhanced meteorological observations and monitoring of land and ocean surfaces for weather forecasting and disaster warning, with state-of-the-art payloads: 6 channel Imager & 19 channel Sounder meteorology payloads, communication payloads viz., The Data Relay Transponder (DRT) and Satellite aided Search and Rescue (SAS&R) transponder.

The DRT instrument has weather forecasting capabilities by collecting meteorological, hydrological, and oceanographic data from Automatic Data Collection Platforms (ADCP) or Automatic Weather Stations (AWS).
