GSAT-29 is a high-throughput communication satellite developed by the Indian Space Research Organisation (ISRO).[4][5] The mission aims at providing high-speed bandwidth to Village Resource Centres (VRC) in rural areas.[6] The two Ku and Ka operational payloads will provide communication services to Jammu and Kashmir and Northeast India under Digital India programme.[7] At the time of launch GSAT-29 was the heaviest satellite, weighing 3,423 kg (7,546 lb),[8] that was placed in orbit by an Indian launch vehicle.[9][10] Approved cost of GSAT-29 is ₹175.63 crore (US$21 million).[11]
Apart from its main communication payload in Ka/Ku bands, GSAT-29 hosts few experimental payloads to mature their technology for use in future spacecraft.[12]
The satellite was launched on 14 November 2018 through the second developmental flight of LVM3,[16] that placed the GSAT-29 satellite into its planned geosynchronous transfer orbit (GTO) over the equator.[17] It joins the Indian National Satellite System (INSAT) fleet in geostationary orbit.[10]
