Technology And Application Of Kinematic Precise Point Positioning

Kinematic precise point positioning technology is a new GPS precise point positioning,the principle is the use of IGS (International GNSS Service) precise orbit and satellite clocksobservational data on a single dual-frequency GPS receiver for kinematic un-differencedtreatment to achieve kinematic positioning accuracy. Because it has an independent, flexibleand high-precision features, so the kinematic precise point positioning technology in the fieldof high-precision kinematic applications with a wide range of application. In this paper, thekinematic precise point positioning technology for the following research:(1) Elaborated the theory of kinematic precise point positioning, including positioningtheory, mathematical models, such as linear combinations of observation equations. Whichfocuses on the precise point positioning three commonly used mathematical models, and madea comparative analysis.(2) Because of the kinematic precise point positioning using a kinematic un-differencedmethod, therefore, is not affected by differential eliminate errors. This paper analyzes the GPSprecise point positioning satellite-related errors, general error on the error associated with thestation, and signal propagation errors and other relevant methods to eliminate or weaken, andalso analyzes the receiver antenna height and phase Center corrections, satellite antenna phasecenter corrections, such as antenna phase error correction term correction wound specialconsideration.(3) Introduces the high-precision GPS data processing software Bernese5.0and CSRS-PPP system, using their kinematic single point positioning module greater impact IGS trackingstation data Wen chuan earthquake on solver analysis, the static simulation of dynamic singlepoint centimeter-level positioning accuracy can be achieved, however, solving one hour data,the instantaneous coordinates decimeter accuracy of the solution, but not stable.(4) Introduced GPSTOOLS software and use the software and CSRS-PPP system solvervehicle kinematic experimental data, the results show that the kinematic decimeter positioning accuracy, but also by a great influence on the quality of observational data.
