OceanSat Scatterometer-2 (OSCAT-2) | |
ScatSat-1 (Scatterometer Satellite-1) is a satellite providing weather forecasting, cyclone prediction, and tracking services to India. It has been developed by ISRO Satellite Centre, Bangalore whereas its payload was developed by Space Applications Centre, Ahmedabad.[1] The satellite carries a Ku-band scatterometer similar to the Oceansat-2 which became dysfunctional after its life span of four-and-a-half years. India was dependent on NASA's ISS-RapidScat for prediction of cyclone forecasting and weather prediction.[2] The data generated by this mini-satellite are used by National Aeronautics and Space Administration (NASA), European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and National Oceanic and Atmospheric Administration (NOAA).
Instruments[]
The designated primary instrument of the satellite is a scatterometer (OSCAT) which is similar to the instrument launched with Oceansat-2. The satellite is built around a standard IMS-2 Bus and the mass of the satellite is 371 kg. The weight of the scatterometer is 110 kg.[2] This satellite measures the wind speed and its direction over the ocean.
Development[]
Space Applications Centre (ASC) of ISRO was responsible for development of the instrument whereas ISRO Satellite Centre, Bangalore was responsible for the bus. ScatSat-1 was being built at 60% of the actual production cost and one-third of the actual predicted time.[3] It was built using leftover parts of other satellite missions.[4]
Launch[]
The satellite was launched on 26 September 2016, at 03:42 UTC, from the first launch pad (FLP) of Satish Dhawan Space Centre, Sriharikota (SHAR) and launched by the PSLV-C35 launch vehicle the first multi-burn technology used by ISRO.[5] The microsatellites Alsat-1B, AlSat-2B and BlackSky Pathfinder-1, and nanosatellites AlSat-1N, NLS-19, PISat and Pratham were launched along with ScatSat-1.[6] It has been the longest Polar Satellite Launch Vehicle (PSLV) mission till date.
ScatSat-1 data[]
ScatSat-1 data are made available to the public through via FTP from the Meteorological and Oceanographic Satellite Data Archive Center, a e-portal maintained by Space Application Centre, Indian Space Research Organisation (ISRO).
Near-real time level 2 ocean wind vectors on a 25 km/50 km swath grid, based on the backscatter measurements of the ScatSat-1 are available through the e-portal of EUMETSAT.
