NEW DELHI: India’s space agency, the Indian Space Research Organisation (ISRO), is set to launch its communication satellite GSAT-20 using Elon Musk’s SpaceX Falcon-9 rocket. This partnership marks a significant moment in India’s space ambitions, reflecting the evolving global dynamics of satellite launches.
Scheduled for the second quarter of 2024, GSAT-20 will be lifted into space to offer high-throughput satellite (HTS) services, aiming to enhance connectivity, especially in remote regions. Weighing 4,700 kg, GSAT-20 will cater to a broad spectrum of needs, including broadband and cellular backhaul services for underserved areas in India, including the Andaman and Nicobar Islands and Lakshadweep.

ISRO’s current flagship launch vehicle, the LVM3, is capable of carrying payloads of up to four tons. However, with GSAT-20 surpassing this weight by 700 kg, ISRO sought an external partner to facilitate its launch. SpaceX’s Falcon-9 rocket, known for its cost efficiency and proven reliability, was selected to bridge this gap. The decision to collaborate with SpaceX comes at a time when ISRO is still developing its own capabilities to handle heavier payloads. Although private satellite entities in India have previously turned to SpaceX due to its competitive pricing, this collaboration highlights the growing trend of commercial space partnerships.
GSAT-20, designed to provide cost-effective Ka-band HTS services, will offer a capacity of nearly 48 Gbps, supporting the growing demand for reliable satellite communication services. It will provide nationwide coverage with 32 beams, ensuring a significant improvement in connectivity across India, particularly in areas where terrestrial infrastructure is limited or unavailable.

While ISRO continues to work on advancing its rocket technologies, including a semi-cryogenic engine designed for heavy payloads, the launch of GSAT-20 represents a practical solution for India’s immediate needs in satellite technology. The agency remains committed to developing its capabilities, with plans to test its semi-cryogenic engine shortly, marking a key milestone in India’s space exploration journey.
