Geo Imaging Satellite or GISAT is an Indian imaging satellite class for geostationary orbit with a high temporal resolution, meant for providing near real time imaging with fast revisit capability and real time monitoring. Two satellites will provide resolution in the range of 42 to 318 m. It will carry multi-spectral (Visible and Near-InfraRed, and Short Wave-InfraRed), multi-resolution (42 to 318 m) imaging instruments.
The first satellite; EOS-3 (aka GISAT-1) was launched on 12 August 2021 but failed to reach orbit as cryogenic upper stage of GSLV could not ignite. EOS-3 was supposed to fulfil civilian applications.
The second satellite, EOS-5 (aka GISAT-2) will be acquired by Indian Navy and will differ slightly in capabilities compared to EOS-03 (aka GISAT-1).
