BENGALURU: The Indian Space Research Organisation (Isro) will make a second attempt to give India its first state-of-the art earth observation satellite, by launching the Geo Imaging Satellite (Gisat-1) by the end of this month or the first week of April.
The launch of Gisat-1 was first scheduled for March 5, 2020, and was scrubbed minutes before the 26-hour countdown was to begin on March 4, 2020.
Isro chairman K Sivan told TOI on Sunday (March 7, 2021): “The date has not been finalised as yet, but we are targetting a launch by the end of this month or in the first week of April.”
The satellite, which will add to Isro’s constellation of earth observation satellites, will be placed in the geostationary or the geosynchronous equatorial orbit (GEO), and will be launched on a GSLV. Once in the GEO, it will subsequently be positioned in geostationary orbit, about 36,000km above Earth’s equator, using onboard propulsion systems.

Designed to provide near real-time images of large areas of region of interest at frequent intervals, the satellite will hold the potential of even aiding the country’s armed forces to plan operations.
“Operating from geostationary orbit, GISAT-1 will facilitate near real time observation of the Indian sub-continent, under cloud free condition, at frequent intervals,” Isro had said last year.
Weighing 2,268 kg, the satellite will also provide spectral signatures for agriculture, forestry, mineralogy, disaster warning, cloud properties, snow, glaciers and oceanography.
It will be equipped with six-band multispectral visible and near-InfraRed imaging sensor with 42m resolution, 158-band hyper-spectral visible & near-InfraRed sensor with 318m resolution and 256-band hyper-spectral short wave-InfraRed sensor with 191m resolution.
