Oceansat-2 is an Indian satellite designed to provide service continuity for operational users of the Ocean Colour Monitor (OCM) instrument on Oceansat-1. It will also enhance the potential of applications in other areas.
The mission objectives of Oceansat-2 are to gather systematic data for oceanographic, coastal and atmospheric applications. The main objectives of OceanSat-2 are to study surface winds and ocean surface strata, observation of chlorophyll concentrations, monitoring of phytoplankton blooms, study of atmospheric aerosols and suspended sediments in the water.
Oceansat-2 is second satellite in the series of Indian Remote Sensing satellites dedicated to ocean research, and will provide continuity to the applications of Oceansat-1 (launched in 1999). Oceansat-2 carried three payloads including an Ocean Colour Monitor (OCM-2), similar to the device carried on Oceansat-1. 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 will carry three payloads for ocean-related studies, namely, Ocean Colour Monitor-2 (OCM-2), a Ku-band Pencil Beam Scatterometer by Indian Space Research Organisation (ISRO), and a payload called ROSA (Radio Occultation Sounder for Atmospheric) developed by the Italian Space Agency (ASI). The major applications of data from Oceansat-2 are the identification of potential fishing zones, sea state forecasting, coastal zone studies, and inputs for weather forecasting and climatic studies.
Oceansat-2 was launched from Satish Dhawan Space Centre, First Launch Pad on 23 September 2009, at 06:21:00 UTC using the Polar Satellite Launch Vehicle (PSLV-C14). India successfully launched its 16th remote-sensing satellite Oceansat-2 and six nano European satellites in 1200 seconds. The 44.4-metre tall, 230-tonne Indian launch vehicle Polar Satellite Launch Vehicle (PSLV) freed itself from the launch pad at the spaceport and lifted itself up, lugging the 960-kg Oceansat-2 and the six nano satellites all together weighing 20 kg.
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. The remaining two, each weighing 8 kg, were attached to the fourth stage. Of the six nano satellites, four are from Germany, one is from Switzerland and one from Turkey. The seventh is a big one, India's Oceansat-2 weighing 960 kg. Soon after the satellites were put into orbit, Indian Space Research Organisation's (ISRO) satellite tracking centres started monitoring them. This was the 16th PSLV mission. Oceansat-2 was successfully deployed to predict the landfall and mitigate the effects of Cyclone Phailin. The scanning scatterometer on Oceansat-2 has been dysfunctional since February 2014.
