GSat 20 [ISRO]
GSAT-20 is an Indian geostationary Ka-band high-throughput communications satellite.
GSAT 20 is built on the Carbon Fiber Reinforced Polymer (CFRP)-based I-4K unified modular bus with electric only propulsion. It features a Ka × Ka high-throughput communications payload with 70 Gbps throughput utilizing 32 spot beams with each 2 polarisations providing broadband services across the Indian region.
The satellite was originally planned to be launched not before 2020 on a GSLV Mk.3 (2) launch vehicle, but was brought forward to a 2019 launch on an Ariane-5ECA+ but had in 2021 reverted back to a GSLV Mk.3 (2) launch. In early 2024 a launch contract with SpaceX for a launch on a Falcon-9 v1.2 (Block 5) was signed.
