What is the primary purpose of ISRO's GSAT-20 (GSAT-N2) satellite?
It delivers high-speed broadband services using Ka-band across India.
GSAT-20, renamed GSAT-N2, is a high-throughput communication satellite owned by NewSpace India Limited (NSIL), ISRO's commercial arm. It was launched on 19 November 2024 on a SpaceX Falcon 9 rocket from Cape Canaveral, USA.
It carries a Ka-band payload with 32 user spot beams (about 48 Gbps throughput) covering the whole of India, including Andaman & Nicobar and Lakshadweep, to provide high-speed broadband and in-flight internet connectivity.
Navigation over the Indian region is the job of the NavIC (IRNSS/NVS) satellites, weather monitoring is done by INSAT-3D/3DR/3DS, and Earth observation by Cartosat, RISAT and other EOS satellites.
Hence, GSAT-20 (GSAT-N2) delivers high-speed broadband services using Ka-band across India.
