基于三差解检测与修复GPS载波相位周跳新方法

A NEW CYCLE SLIP DETECTION AND CORRECTION METHOD USING TRIPLE DIFFERENCES SOLUTION

对飞行中（Ｏｎ－Ｔｈｅ－Ｆｌｙ）初始化载波相位整周模糊度ＧＰＳ动态差分定位而言，如果在整周模糊度初始化过程中发生载波相位周跳，将严重影响整周模糊度的确定。本文对已有的ＧＰＳ静态差分定位中通过三差解检测与修复周跳的方法进行了推广，提出了一种适合于解决Ｏｎ－Ｔｈｅ－Ｆｌｙ整周模糊度初始化过程中周跳问题的新方法。新方法保持了静态情况下原有方法的特点，分析和利用实采数据进行的检验表明，新方法是有效和实用的。

In OnTheFly DGPS kinematic positioning, the cycle slip occurred in the period of integer ambiguity initializating must be carefully removed. In this paper, this kind of cycle slip is considered by using triple differences solution, and a new method is developed. A test is carried out and implies that the new method is effective and reliable.
