Launch Date: 23.09.2009


Oceansat-2, the second in the series of Oceansat Series, is envisaged to provide continuity of operational services of Oceansat-1(IRS-P4) with enhanced application potential. It carried three payloads: Ocean Colour Monitor (OCM-2); Ku-band Pencil Beam scatterometer (OSCAT), and Radio Occultation Sounder for Atmosphere (ROSA) developed by the Italian Space Agency.

The major objectives of Oceansat-2:

  • Design, develop, launch and operate a state of art 3-axis body stabilized satellite providing ocean based remote sensing services to the user communities.
  • Establish ground segment to receive and process the payload data.
  • Develop related algorithms and data products.
  • Serve in well established application areas and also to ensure the mission utility.
  • Enhanced applications with the availability of new scatterometer.
