摘要 介绍了利用准电离层(QIF)方法和MW(Melbourne—Wubbena)方法进行模糊度固定的原理,在得到的卫星轨道浮点解的基础上,用两种方法分别进行了模糊度的固定。并分析了两种方法对于不同长度基线的模糊度固定成功率。结果显示:在固定模糊度的成功率上,Mw方法优于QIF方法,在基线长度为1000~4000km时,两种方法都保持着较高的模糊度固定成功率。 This paper studied the and Q1F me two methods to fix t thod, he am bigui d on the ty, then imental results show that MW method line between 1000 and 4000 kilometers, ambiguity. principle of ambiguity decomposition with the MW GPS navigation satellite orbit float solution, we use analysis the success rate of two methods.
