| 摘 要： | 目前,GPS全球定位技术正以日新月异的速度向前发展,并且正在全面取代常规测量技术,但它却忽视了一些必须解决的问题,比如天线高对GPS定位的影响到底有多大等。由于GPS定位的内业数据处理结果有基线解算和无约束平差两个中间结果,以及约束平差结果一个最终结果,所以文章先分析天线高对基线解算结果的影响,再分析天线高对无约束平差结果的影响,最后分析天线高对约束平差结果的影响。

| Abstract: | At present,GPS global-positioning technology is being developed forward at the speed with rapid change and going to replace the routine measures technology. But people ignored some problems that must be solved, such as how big influence of height of antenna is on GPS positioning. Because the interior data result of GPS positioning has base-line solving and calculating, unconstraint adjustment, and constraint adjustment, so the author analyzes the influence of height of antenna on base-line solving and calculating at first, then unconstraint adjustment, constraint adjustment at last. |
