India’s space agency, the Indian Space Research Organisation (ISRO), is preparing to launch its communication satellite GSAT-20 aboard SpaceX’s Falcon-9 rocket. This collaboration underscores India’s expanding space ambitions and the shifting landscape of global satellite launches.

Set for the second quarter of 2024, the GSAT-20 satellite, weighing 4,700 kg, will deliver high-throughput satellite (HTS) services to enhance connectivity, particularly in remote areas. Its services will include broadband and cellular backhaul for underserved regions, including the Andaman and Nicobar Islands and Lakshadweep.

ISRO’s current flagship launch vehicle, the LVM3, can carry payloads up to four tons, but with GSAT-20 exceeding this by 700 kg, ISRO opted to partner with SpaceX. Known for its cost efficiency and reliability, the Falcon-9 rocket will help fill the gap in ISRO’s capabilities, as the agency is still developing its own heavy-lift launch vehicles. This partnership reflects a broader trend of commercial space collaborations, with private Indian satellite companies also relying on SpaceX’s competitive pricing.

GSAT-20 is designed to provide cost-effective Ka-band HTS services, with a capacity of nearly 48 Gbps, improving satellite communications nationwide through 32 beams. This will greatly enhance connectivity in areas lacking terrestrial infrastructure.

While ISRO advances its own rocket technology, including a semi-cryogenic engine for heavy payloads, the GSAT-20 launch offers an immediate solution to India’s satellite needs. The agency plans to test its semi-cryogenic engine soon, marking a significant step in India’s space exploration progress.
