GSAT-20 also known as CMS-03 or GSAT-N2 is a communication satellite jointly being developed by Indian Space Research Organisation Satellite Centre and Liquid Propulsion Systems Centre.[4] GSAT-20 is funded, owned and operated by New Space India Limited, though the communication capacity will be leased to Dish TV.[5][6][7] The satellite is intended to add data transmission capacity to the communication infrastructure required by India's Smart Cities Mission.

It will be India's first satellite to rely entirely on electric propulsion, which can be five to six times more efficient than chemical-based propulsion.[4]

Payload

The satellite features a Ka-band high-throughput communications payload with 70 Gbit/s[8] throughput utilizing 40 beams, offering HTS capacity of nearly 48Gbps.[9] Each beam will have 2 polarisations, effectively making them 80 beams.[10]

Launch

The satellite was initially expected to be launched in 2024 on an LVM3,[11][12][13] but the satellite is ~700kg heavier than the maximum capacity of LVM3.[3]

As a result, the commercial arm of ISRO (New Space India Limited) signed a contract with SpaceX to launch GSAT-20 aboard Falcon 9 in the second quarter of 2024. The deal signifies a significant shift for ISRO, which until now has relied on Arianespace to launch satellites too heavy to fly on domestic launch vehicles.[3]
