India to Launch GISAT-1 Earth Observation Satellite in March

Indian Space Research Organisation (ISRO) is planning to launch the GISAT-1 (Geo Imaging Satellite 1) Earth observation satellite in March.

The satellite will be launched abroad a Geosynchronous Satellite Launch Vehicle (GSLV-F10) rocket from the Second Launch Pad of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch is tentatively scheduled at 1743 Hrs IST on March 05, 2020, subject to weather conditions.

Weighing about 2275 kg, GISAT-1 is a state-of-the-art agile Earth observation satellite which will be placed in a Geosynchronous Transfer Orbit (GTO) by GSLV-F10. Subsequently, the satellite will reach the final geostationary orbit (GEO) using its onboard propulsion system.

Operating from geostationary orbit, GISAT-1 will facilitate near real-time observation of the Indian subcontinent, under cloud-free conditions, at frequent intervals.

A 4-meter diameter Ogive shaped payload fairing is being flown for the first time in this GSLV flight. This is the fourteenth flight of the GSLV.

GEO Imaging Satellite (GISAT)

GEO Imaging Satellite or GISAT is a planned Indian geo-imaging satellite class for providing images quickly during disasters.

Two identical satellites are planned which will provide resolution in the range of 50 m to 1.5 km. They will carry multi-spectral (visible, near infra-red and thermal), multi-resolution (50 m to 1.5 km) imaging instruments.

GISATs will feature five types of multispectral cameras and 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.
