摘要
介绍了基于传统模型和UofC模型的两种精密单点定位算法;利用自主开发的精密单点定位软件实现了这两种算法。为了比较两种精密单点定位模型的动态定位精度、收敛时间以及解算速度,收集了船载和机载的动态GPS观测数据进行解算实验。实验结果表明:两种模型的动态定位精度和收敛时间相当,传统模型的解算速度约为UofC模型的2倍。
An introduction of two kind of precise point positioning model： traditional model and UofC model was presented. Both the two models were included in the software developed by the author. In order to compare the two precise point positioning models in three aspects, including kinematic positioning precision, convergence time and computing speed, experiments were carried out with dynamic GPS data collected from seaborne and airborne vehicles. The result showed that the two models shared equivalent positioning precision and convergence time, while traditional model enjoyed higher computing speed than UofC model.
