Research on Precise Clock Corrections Densification Based on Epoch Differential Model
Abstract In this paper,an epoch-difference GNSS clock densification algorithm is tested.The high precision relative satellite clock bias is obtained by epoch-difference carrier phase observation.By using relative clock results,the high-rate 30 s satellite clock products are then densified from IGS 5 min interval precise satellite clock products.The results show that compared with mathematical interpolation methods,the epoch-difference clock densification algorithm has better performance.The densification precision using the epoch differential model is below 0.03 ns.Furthermore, the differential among different types of satellite clock is small.
Key words :
