Communication satellites:
GSAT-19E · Payload for the first developmental flight of GSLV MK-III · Experimental satellite to act as test bed for several new technologies like unified modular bus, deployable thermal radiators, electrical propulsion, indigenous Li-Ion batteries and C-band TWTAs, optical payload, etc.
Launch: dec, 2016.
GSAT-11 : Multibeam satellite with about 10 Gbps throughput · 32 User beams in Ku-band, 4 colour-frequency reuse · Hub communication in Ka-band · Use of latest technologies like multiple spot beams, onboard RF tracking, high capacity modular bus supporting 4000-6000 kg mass, etc.
GSAT-11 to be located at 74 deg E is an advanced communication satellite with multi spot beam antenna coverage over Indian mainland as well as Islands to bring-in a huge advantage to the user community, compared to the existing INSAT/GSAT satellite systems. With this new system architecture and the advanced technology elements proposed to be employed for realization will generate a capacity of more than 10 Gbps for users from a single platform. The payload configuration is compatible with advanced I-4K bus of ISRO. The frequency re-use scheme designed into the system for the use of the allocated Ku band spectrum will provide more than 200 # 36MHz equivalent transponders.
The main highlights of the system configuration are multi beam coverage, Star network based Gateway connectivity, ACM as fade mitigation techniques, on-board power management techniques etc.
In addition to the advanced on-board technologies that are considered, the ground system technologies with user terminals employing Adaptive Coding & Modulation techniques, site diversity for Ka band Hub stations & sizing for fade mitigation etc are built into the design of overall system.
