Oceansat-2 is an Indian satellite designed to provide service continuity for operational users of the Ocean Colour Monitor (OCM) instrument on Oceansat-1.

[2] The mission objectives of Oceansat-2 are to gather systematic data for oceanographic, coastal and atmospheric applications.

Data from all instruments are made available to the global scientific community after the post-launch sensor characterization, which is expected to be completed within 6 months of the launch.

Oceansat-2 carry three instruments for ocean-related studies, namely, Ocean Colour Monitor-2 (OCM-2), an OceanSat Scatterometer by Indian Space Research Organisation (ISRO), and an instrument called ROSA (Radio Occultation Sounder of the Atmosphere) developed by the Italian Space Agency (ASI).

In copybook style, the launch vehicle first flung out Oceansat-2 at an altitude of 720 km above the Earth in a Sun-synchronous orbit (SSO), followed by the four nano satellites – also called Cubesats – each weighing 1 kg.
