Application of AsiaSat-3S satellite in CAPS system

CAPS is an integrated system of navigation and communication. The orbit position AsiaSat-3S satellite has been pushed from 105.5E to 147.5E. It become a SIGSO satellite, which plays certain role in improving the constellation DOP system. According characteristic parameters (mainly including parameters, polarization frequency offset etc.), this paper expounds changes azimuth, elevation angle 16-meter paraboloid antenna Tianjin pointing tracking ground system, analyzes dynamic transponder through spontaneous receiving signals parameter model prediction repeater good reference value.
