THE THEORY OF GPS-BASED GEOMETRIC ORBIT DETERMINATION FOR LOW-EARTH SATELLITE
摘要
Abstract
Methods of single frequency carrier phase-basedrelative orbit determination (OD) and kinematic network OD for low-earthsatellite are developed. From the results calculated using L1 datacollected by GPS/DR onboard Topex/Poseidon, we can draw followingconclusions: (a) the accuracy of single frequency carrier phase-basedrelative OD may attain the order of a few decimeters; (b) the accuracyof relative OD depends on the data quality of ground tracking stations; (c)the accuracy of kinematic network OD is equavalent to a weighting amongrelative ODs of different ground tracking stations and can improve the reliabilityand precision of OD due to its redundant condition and goodgeometric configuration.关键词
