Mission background

The Indian Space Research Organisation (ISRO) proposed OceanSat-2 to provide service continuity for the operational users of the OCM (Ocean Colour Monitor) instrument launched in 1999 on board the predecessor IRS-P4/OceanSat-1 mission.

Satellite design

OceanSat-2 is a three-axis stabilised spacecraft configured around the proven IRS bus along with improved mission-specific subsystem designs. The main structure is made up of a CFRP (Carbon Fibre Reinforced Plastic) composite cylinder with a PSLV interface ring. The thermal design of the spacecraft employes both passive and active control elements.


Mass 958 kg
Design lifetime 5 years

Mission Operations

Polar Sun-synchronous with an altitude of 720 km and an orbit period of 99 minutes. Revisit time is two days.

The ground segment elements for OceanSat-2 include the SCC (Spacecraft Control Centre) at ISTRAC (ISRO Telemetry, Tracking and Command Network), Bangalore; the payload data reception station at NRSA (National Remote Sensing Agency) Shadnagar; data processing, data product generation and dissemination to users at NRSA, Balanagar, Hyderabad; data product software development at SAC (Space Application Centre), Ahmedabad; and development of mission software, flight dynamics software and mission management at ISAC (ISRO Satellite Centre), Bangalore, India.
