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.[6] Two identical satellites will provide resolution in the range of 50 m to 1.5 km.[2]·[7] It will carry multi-spectral (visible, near infra-red and thermal), multi-resolution (50 m to 1.5 km) imaging instruments.[8]

Launch of the first satellite to geostationary orbit is planned for 5 March 2020.[5]·[9]·[10]

Abilities

GISAT-1 in deployed configuration

GISATs will image in multi-spectral and hyper-spectral bands to provide near real-time pictures of large areas of the country, under cloud-free conditions, at frequent intervals which is, selected field image in every 5 minutes and entire Indian landmass image every 30 minutes at 50 m spatial resolution.[2]·[7]

Features of GISAT-1 are:

Imaging capabilities of GISAT-1[7]
Band Channels Ground Resolution(m) Range(μm)
Multispectral (VNIR) 6 50 0.45 – 0.875
Multispectral (LWIR) 6 1500 7.0 – 13.5
Hyperspectral (VNIR) 60 500 0.375 – 1.0
Hyperspectral (SWIR) 150 500 0.9 – 2.5
