IIT Madras Alumni Build OptoSAR Satellite, Plan 30-Satellite Constellation
An exhibition at Bharat Mandapam in New Delhi highlighted India's emerging prowess in defence and space technologies, spotlighting private sector innovations developed alongside the Indian Space Research Organisation. Among the featured innovations is OptoSAR, a 190-kilogram satellite designed by IIT Madras alumni that combines optical payloads and synthetic aperture radar. The satellite simultaneously captures images through clouds, smoke, and nighttime conditions, serving defence operations, flood monitoring, and forest fire management. Following the launch of Mission Drishti in May, developers aim to build a constellation of 30 satellites within three years to cater to global requirements. The initiative reflects growing government backing and grants aimed at expanding India's private space tech sector.
