CAPS Satellite Data Push Communications System

For the application needs of CAPS (Chinese Area Positioning System) in a particular field, we design and implement the CAPS satellite data push communications system. The system mainly includes data transmission equipment in the satellite central station (document broadcast software, data packers, jammers, modulators, high power amplifier and antenna), Slightly Inclined Geo-Synchronous Orbit satellite, receiving terminal equipment (terminal antenna tracking SIGSO satellite, receiver front-end processing, receiver demodulation processing). The system has a data transfer rate of 4Mbps in satellite data push, which is well to meet the application needs in relevant field.
