India to Launch GEO Imaging Satellite

India planned to launch its first GEO imaging satellite, GISAT-1, in April 2021 to provide frequent near-real-time imagery of the Indian subcontinent and border areas.

26 March 2021: India announced plans to launch India’s first Geo Imaging Satellite (GISAT-1) during the first or second week of April.

– GISAT-1 was previously planned for launch on 5 March and then 28 March. Both dates were delayed due to minor technical issues.

– GISAT-1 will operate on an orbital slot around 93.5° East, colocated with Insat 3A, Insat 4B and GSat 15.

– The mission of GISAT-1 is to facilitate continuous observation of Indian sub-continent, quick monitoring of natural hazards and disaster.

– GISAT carries an imaging payload consisting of multi-spectral (visible, near infra-red and thermal), multi-resolution from 50 m to 1.5 km. It will provide pictures of the area of interest on near real time basis including border areas.

– The satellite was originally planned to be launched in 2017 or 2018. GISAT-1 details.

GISAT will provide near real time pictures of large areas of India, under cloud free conditions, at frequent intervals. That is, selected Sector-wise image every 5 minutes and entire Indian landmass image every 30 minutes at 50 m spatial resolution. Of particular interest to Indian authorities are the northern Indian borders. India, which has been involved in several border skirmishes with China, is aggressively building up its infrastructure to defend its territory. Employing this satellite will provide India with the capability to observe and preemptively position itself against Chinese troop movements on its border.
