基于UofC模型的精密单点定位精度分析

EVALUATION OF PRECISE POINT POSITIONING WITH UofC MODEL

介绍基于UofC模型的精密单点定位的基本原理，综合考虑各种误差改正，实现了基于UofC模型的精密单点定位算法。采用静态和多种动态条件下（动态数据来源于陆地、空中和海上的运动载体）的实测数据进行解算实验并从外符合的角度对算法的定位精度进行评估。实验结果表明：所实现算法的静态定位精度可达到2—3cm，动态解算精度可达到10～20cm。

Basic principle of precise point positioning （PPP） with UofC model was introduced. By comprehensively considering varied error correction models the PPP algorithm based on UofC model has been realized. Experiments with static and various dynamic data（which came from land,air and marine vehicles） were carried out to evaluate the accuracy of positioning results with PPP algorithm. It is demonstrated that accuracies of 2 - 3 cm and 10 - 20 cm can be achieved for static and kinematic positioning respectively.
