GSAT-20 is an Indian geostationary Ka-band high-throughput communications satellite. GSAT 20 is reportedly built on the I-6K unified modular bus and features a Ka-band high-throughput communications payload with 70 Gbps throughput utilizing multiple spot beams providing broadband services across the Indian region. It will be the first fully Electric Propulsion/EP enabled satellite which can be five to six times more efficient than chemical-based propulsion. It will be the first ISRO made satellite to move from Geostationary transfer orbit to Geosynchronous orbit using Electric Propulsion.
Limiting rule: No flight through a thick (>4500 ft) cloud layer extending across the freezing level.
max-top 6752 m, mean 4632 m, 75% cover, freezing 4763 m · max cloud-top 6752 m above freezing 4763 m (75% cover in 10 nmi) · no GLM flashes within 25 nmi / 30 min, likely cirrus / stratiform ice rather than cumulus
