India's GSAT-20 rides SpaceX Falcon-9 to orbit: New satellite set to revolutionise telecom infrastructure

Send Push
On November 18, 2024, at 12:01 AM IST, India achieved a significant milestone with the launch of GSAT-20 aboard SpaceX’s Falcon-9 rocket. This marks the first time NewSpace India Limited ( NSIL), the commercial arm of ISRO, has partnered with SpaceX for satellite deployment. The satellite separated from the rocket 34 minutes post-launch and was successfully placed into its geosynchronous transfer orbit.

In an earlier TOI report, NSIL Chairman and Managing Director Radhakrishnan D emphasized the importance of the collaboration, stating, “SpaceX was selected against an RFP we had floated last year. There were other bidders too. This marks a new beginning as we launch on a US rocket from their soil. The present agreement is only for this launch, and we will look at future requirements as and when we need.”

Key Features of GSAT-20
The GSAT-20 satellite represents a cutting-edge advancement in satellite communication technology, with features tailored to meet India’s growing connectivity needs.

  • High Data Capacity: With a throughput of 48 Gbps across 32 beams, the satellite ensures robust broadband coverage, extending to remote areas like the Andaman, Nicobar, and Lakshadweep Islands.
  • Ka-Band Technology: Utilizing the Ka-band frequency, GSAT-20 is designed to support in-flight internet services and Smart Cities initiatives.
  • Durability and Efficiency: The satellite is engineered for a 14-year mission life and features advanced materials, including CFRP structures and Li-ion batteries.

Demand-Driven Model
This launch is part of the Indian government’s 2020 space sector reforms, which mandate NSIL to develop satellites based on service demand. GSAT-20 is NSIL’s second demand-driven satellite after GSAT-24, which was launched in 2022 and leased entirely to Tata Play.


Unlike GSAT-24, which served a single client, GSAT-20 will cater to multiple users. An official noted in a TOI report, “While this is also a dedicated satellite, it is not meant for a single company. There are multiple players in the fray.”

Why SpaceX Was Chosen
Historically, India relied on French Arianespace rockets for launching heavier satellites. However, the 4,700 kg GSAT-20 exceeded the capacity of India’s launch vehicles, prompting NSIL to choose SpaceX’s Falcon-9 through a competitive bidding process.

The partnership with SpaceX not only marks a new chapter for NSIL but also reflects India’s increasing engagement with international space agencies.

India’s Expanding Space Ambitions
NSIL, established as part of India’s push to commercialize space, is tasked with owning, operating, and funding satellite missions to meet market needs. Its first demand-driven mission, GSAT-24, launched in June 2022, set a precedent for private sector involvement in India’s satellite industry.

With the GSAT-20 launch, NSIL is furthering its mission to enhance connectivity infrastructure across India. This aligns with the government’s vision to leverage space technology for national development, especially in bridging the digital divide.

In June 2022, NSIL successfully launched its first demand-driven satellite mission, GSAT-24 (now called GSAT-N1), which is fully leased by TataPlay. “While this is also a dedicated satellite, it is not meant for a single company. There are multiple players in the fray,” an official told TOI.

Implications and the Road Ahead
The successful launch of GSAT-20 highlights India’s evolving approach to space exploration, combining domestic expertise with global partnerships. As connectivity becomes increasingly vital for Smart Cities, in-flight internet, and remote regions, GSAT-20 is poised to play a crucial role.

This mission underlines India’s ability to innovate in satellite technology while leveraging international platforms to realize its ambitions, marking another significant step in the country's space journey.
