| Abstract: | Aiming at the drawbacks in seacoast control surveys, this paper studies several optimizing calculating methods of precise point positioning which include deleting observation time in poor conditions, shortening observation time, substituting precise ephemeris with quick ephemeris and using quick ephemeris calculation to shorten observation time, and proposes two optimized calculating schemes based on analyzing the advantages and disadvantages of the above methods. Experimental result shows that the proposed schemes can reduce the worker＇ s load and meet the needs of seacoast control surveys. |
