  • In this paper,a novel scheme of GEO orbit determination was proposed,which cancelled out the receiver clock error and others system errors by single difference(SD) between the two observations of different satellites at the same epoch on the same station.The basic theory and some key techniques of parameter selection,station distribution and reference satellite selection,etc.were discussed in detail by simulation cases.The simulated results reveal that the receiver clock error could be cancelled out and the parameters of the satellite orbit could be calculated directly.Also,the scheme reduces the burden of station clock synchronization.An optimized scheme was put forward by simulation cases to select satellite pairs and set observing stations under current situation.High precision orbit of 22 parameters could be obtained by the proposed scheme.
