GSAT-7 Communication payload to be located at 74 deg East is configured to provide wide range of service spectrum from low bit rate voice to high bit rate data communication. GSAT-7 Communication payload is designed to provide communication capabilities to users over a wide oceanic region including the Indian land-mass. The payload configuration is compatible with extended I-2K bus of ISRO. The GSAT-7 payload design includes Multiband operation in S, UHF, C & Ku bands, Multi-beam coverage in C and Ku-band, Star & Mesh network based connectivity etc.
The payload system will support services which can be classified into two broad groups:
1. Low Bit Rate for speech, data & Fax services
2. High Bit Rate for high quality Audio-video services
Many new RF subsystems are developed for the first time to cater to the communication requirements
Type/Applications: Communications
Orbit Location: 74°E Geo
Mission Life: 15 Years
Configuration: I2K bus
G Sat7 launch on August @ 74* East
GSAT-7 / INSAT-4F is a multi-band satellite carrying payloads in UHF, S-band, C-band and Ku-band. It is planned to be launched during 2011 onboard GSLV and positioned at 74º East. The satellite weighs 2650 kg with a payload power of 2000 W and mission life of 9 years.
INSAT-4 series is planned to have seven satellites, INSAT-4A through INSAT-4G with INSAT-4D as a spare. The transponder capacity of this series has been worked out after evaluating the requirement projected by different uses/user departments. It is planned that, by 2007, INSAT system will have about 250 transponders in various bands catering to a demand of up to 11 Giga Bits Per Second (GBPS) capacity.

Now friends, its the time for Gsat 7. It will launch in 24 August. It carries 4ku and 3c band TPs. Hope that this new satellite will work fine and will get additional space for channels.
