基于卫星高度角的GPS观测量随机模型分析

摘要

This paper have done the works on the equal precision method and the method based on satellite elevation to fix on the stochastic model of GPS observation and checked out the different methods of fixing on weight matrix work. According to result of the experiment, it diseussed the influences of the results on integer ambiguity resolution and baseline by choosing satellite elevation which fix on weight matrix.%本文主要研究了等权法和基于卫星高度角的GPS观测量随机模型确定方法，由此确定权矩阵应用于GPS基线解算中以检验其效果；并通过对模型试验结果的比较，分析说明了采用卫星高度角定权对整周模糊度搜索和基线解算结果的影响。
