GSAT-5P

GSAT-5P, or GSAT-5 Prime, was an Indian communications satellite which was lost in a launch failure in December 2010. Part of the Indian National Satellite System, it was intended to operate in geosynchronous orbit as a replacement for INSAT-3E.

==Satellite== GSAT-5P was a spacecraft, which was built by the Indian Space Research Organisation based on the I-2K satellite bus. ISRO also launched the satellite, and was to have been responsible for its operation. It was equipped with 36 transponders operating in the G/H band of the NATO-defined spectrum, or the C band of the older IEEE spectrum. Twelve of the transponders operated on extended frequencies within the band. GSAT-5P was expected to operate for at least 12 years, and would have been placed at a longitude of 55 degrees east.
