OceanSat-1 or IRS-P4 is the first Indian satellite built specifically for Ocean applications. It is a part of the Indian Remote Sensing satellite series. The satellite carried Ocean Colour Monitor (OCM) and a Multi-frequency Scanning Microwave Radiometer (MSMR) for oceanographic studies.
History
Oceansat-1 was launched by ISRO's PSLV-C2 along with German DLR-Tubsat and South Korean KitSat 3 on 26 May 1999 from the First Launch Pad of Satish Dhawan Space Centre in Sriharikota, India. It was the third successful launch of PSLV.[2] It was the 8th satellite of the IRS satellite series of India.[3]
Payloads
Oceansat-1 carried two payloads. The first of these, the Ocean Colour Monitor (OCM), is a solid state camera literally designed primarily to monitor the colour of the ocean,[4] thereby useful for documenting chlorophyll concentration, phytoplankton blooms, atmospheric aerosols and particulate matter.[1] It is capable of detecting eight spectrums ranging from 400 nm to 885 nm, all in the visible or near infrafred spectrums.[5] The second, the Multi-frequently Scanning Microwave Radiometer (MSMR), collects data by measuring microwave radiation passing through the atmosphere over the ocean.[6] This offers information including sea surface temperature, wind speed, cloud water content, and water vapour content.[1][6]
Mission completed
Although initially launched with a lifespan of 5 years, Oceansat-1 completed its mission on August 8, 2010 after serving for 11 years and 2 months.[2]
