Cors Station System Positioning Accuracy Analysis And Detection Methods

In order to studying positioning accuracy and the detection method for GPS Continuously Operating Reference Stations (CORS)System; this paper systematically introduces the mathematical model for computing network RTK corrections and mainstream technology that the network RTK commonly used,which analyzes a variety of interpolation model that impacts the rover positioning accuracy and it compared commonly used network RTK technology in the mathematical model, solving the base station, calculating precision stability。It analyzes impact of network RTK positioning accuracy on the spatial correlation of the error sources of error and summarizes the commonly used methods of testing accuracy and a new detection method of testing accuracy is proposed in different environments, It introduced non-parametric statistical estimation analysis; Finally, as to the specific test results, it firstly uses the static detection meathead to detect accuracy of CORS, and later it analysis specific test results using space factor Method。This paper based on summarizes the reliability of positioning accuracy of CORS method that has been detected (known as static detection method, real-time dynamic observed and compared the results after the detection method, the geometric dynamic rules track detection methods, the relative length of the baseline detection method, different epochs detection method and the elevation of detection, etc.)。it proposed new space factor detection, which makes method of the location system detection accuracy more complete. Meanwhile, taking a city's CORS positioning accuracy test as an example, it analyses accuracy of monitoring data, and internal and external line and gives the recommendations of detection drawback。...
