ScatSat-1 (Scatterometer Satellite-1) was a satellite providing weather forecasting, cyclone prediction, and tracking services to India.

[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.

ScatSat-1 data are made available to the public through via FTP from the Meteorological and Oceanographic Satellite Data Archive Center, an e-portal maintained by Space Application Centre, Indian Space Research Organisation (ISRO).

Near-real time level two ocean wind vectors on a 25 / 50 km (16 / 31 mi) swath grid, based on the backscatter measurements of the ScatSat-1 are available through the e-portal of EUMETSAT.

Data services of ScatSat-1 were discontinued after an irrecoverable TWTA instrument failure occurred on 28 February 2021.
