对Blewitt周跳探测与修复方法的改进

Improving of Cycle-slip Detection and Correction of Blewitt Method

在简单介绍Blewitt方法的基础上,针对其存在的一些问题,在野值剔除、周跳探测与修复和模糊度解算方面提出了新思路和算法,从误差角度讨论该方案的可行性. 实例分析表明:改进后的方法对周跳探测更“干净”、合理、可行.

On the basis of introducing Blewitt method, new idea and arithmetic were put forward on bad observations deletion, cycle-slip detection and correction, and ambiguity float solution in allusion to some questions of Blewitt method. To discussed the feasibility from error theory and to analyze it with some samples, it was tested: cycle-slip detection was more clean and more reasonable and viable after improving.
