精密单点定位中误差改正模型研究与分析

Study and Analysis on Error Models of Precise Point Positioning

研究分析了重要的3种误差源模型,简单介绍了其它误差改正方法。利用上述误差改正模型方法,得到精密单点定位总模型,利用这个模型对多个历元数据进行解算,并与非改正结果进行了比较、分析,结果表明模型能够显著提高单点定位的精度。

The paper analyzed each models of three important error source, introduced amend methods of other models. Composited these models to a general model of precise point positioning. Calculated many units of datas by this model and be compared and analyzed. It proved that this model can raise much more accuracy.
