Research on GPS-based Orbit Determination with Carrier Phase for Low-o rbit Satellites
星载GPS载波相位相对定轨方法研究

More and more GPS receivers are onboard low-orbit sat ellites for orbit determination, which can be applied to remote sensing, meteoro logy and sea surface altitude determination. The method of ambiguity resolution for relative orbit determination with carrier phase is proposed. Some criteria a re developed to identify correct ambiguities. With the method, the accuracy of c a rrier phase-based relative orbit determination may attain the order of a few de cimeter from the results calculated by using data collected from GPS/DR onboard TOPEX/POSEIDON.
