针对常规的GPS观测数据仿真方法的缺陷,提出了一种利用IGS数据产品进行高精度GPS观测数据仿真的方法.基于GPS定轨定位原理及数学模型,编制了相应的仿真程序.实例仿真结果表明文中的仿真方法能达到2米级的精度,具有较高的应用价值.
A high precise GPS observation simulation method using IGS data products was proposed, which overcomes the limitations of conventional method. According to the mathematical models of GPS positioning and orbit determination, some programs were compiled for data testing. The precise from the simulation testing is about 2m, therefore the simulation observations have high applied cost,
