GSAT-15 is an Indian communication satellite similar to GSAT-10 to augment the capacity of transponders to provide more bandwidth for Direct-to-Home television and VSAT services. It was successfully launched on 10 November 2015 at 21:34:07 UTC aboard an Ariane 5 rocket, along with the ArabSat 6B satellite.^[6]

Payload

The satellite carries 24 K_u band transponders and a GAGAN navigational payload operating in the L1 and L5 bands.^[1]^[7] Besides that it will also carry 2 K_u band beacons.^[1]

Satellite

GSAT-15 has an estimated lifespan of 12 years. It will augment telecommunication, Direct-to-Home and radio navigation services.^[8]^[9]

Cost

Cost of launch and insurance: about ₹860 Crore.^[10]
