The GSAT-20 satellite, scheduled for launch in the second quarter of 2024, represents a significant advancement in India’s space capabilities. Operated by NewSpace India Limited and developed jointly by the Indian Space Research Organisation (ISRO) and the Liquid Propulsion Systems Centre, this mission marks the first time ISRO is partnering with SpaceX, using their Falcon 9 rocket. The GSAT-20, weighing 4,700 kg and employing electric propulsion, is designed to enhance India’s communication infrastructure, particularly supporting the Smart Cities Mission. It features a high-throughput Ka-band communications payload, capable of delivering 70 Gbit/s throughput across 40 beams, effectively creating 80 polarizations for extensive coverage, including remote areas of India. This mission underscores India’s commitment to advancing its satellite communication technology while addressing challenges such as the satellite’s heavyweight.
