| 摘 要： | 应用文献[1]中提出的关于粗差定位的逐个搜索法,研究了GPS基线向量网的粗差定位问题;同时改进了粗差定位的逐个搜索法。通过研究以及大量的粗差定位试验表明;应用改进的逐个搜索法进行多个粗差定位,只要粗差个数满足ng≤1.95nb-3p+3,且任一点上至少有三条基线通过,则不论粗差位于何处,都能正确定位,并较准确地给出粗差的估值。文中还对GPS网的布网方案提出了合理的建议。

| Abstract: | This paper studies the locating of blunders for GPS network by using the method of one-by-one searching which was presented by Wang Xinzhou(1992),and the method is further approved in the paper.It is shown that when the following two conditions are satisfied in GPS network,blunders can be located correctly with the improved method,and the estimators of blunders can also be made.These two conditions are:ng≤1.95nb-3p+3;Any point should have relations to at least three baselines. |
