摘要
针对现有GNSS导航卫星多维粗差定位算法研究较少,本文提出采用全局-局部测试法查找观测值中的粗差。从函数模型方面详细论述全局测试和局部测试判断并定位粗差的过程,并且结合蒙特卡罗方法模拟的导航实验数据验证本文所提出的方法。模拟实验表明,该方法能比较快速且准确地定位含粗差观测值,从理论上补充了GNSS导航卫星多粗差定位的算法,也在一定程度上提高了多星座导航完备性。
According to the fact that there is no enough study on the algorithm of GNSS navigation satellites muhi-dimensional gross errors location, this paper presented the global and local test methods to find the gross errors in observations. It described the whole process of the global and local test methods in detail. And it verified the proposed method combining with the navigation experi- mental data simulated by Monte Carlo method. The results of simulation experiment indicated that the observation gross errors could be detected quickly and accurately by this method. This algorithm of GNSS navigation satellites muhi-dimensional gross errors location could improve the RAIM of multi-constellation navigation to some extent.
