The Indian Navy plans to purchase a specialised earth imaging satellite Geo Imaging Satellite-2 (GISAT-2), this fiscal year as part of its modernisation and network-centric combat and communications programme. The satellite, if operational, is likely to improve the navy’s operating capabilities in the Indian Ocean region, which is strategically and geopolitically crucial, especially given China’s growing influence.

KEY POINTS:
Satellites in the GISAT family:
The GISAT-2 will be designed to deliver near-real-time photos of vast regions of interest at regular intervals, assisting the navy not just in surveillance but also in operations planning. The satellite, which will operate from a geostationary orbit (GEO), will also allow for near-real-time observations in cloud-free situations.
GISAT-2, a 2+tonne class satellite, will be built on the modified I-2k satellite bus, just like GISAT-1. In August of last year, Isro failed to launch GISAT-1 into orbit when the GSLV-Mk2 carrying it suffered faults in the cryogenic upper stage, causing the mission to fail. The mission in August 2021 was the space agency’s third attempt to launch the satellite; the first two failed for various reasons.
