摘要
利用GPS进行载体航向的确定,需要从整周模糊度解算和航向解算两个方面进行处理。采用改进的最小二乘解算整周法,并利用在GPS软件接收机,对真实卫星数据进行了处理,通过对航向角精度进行分析,对比不同基线长度时的定向结果,证明了该方法的有效性。
There are two parts in solving the determination of the carrier by measuring carrier phase of GPS,which are the integrate ambiguity and determination solution. The software receiver applying the least square algorithm and validity of the advancement is proved by handling the satellite data. At the same time, the article includes the error analysis of the heading angle and compares the results of different length of the baseline.
