| 摘 要： | 周跳探测是单频精密单点定位的难点之一。本文分析了3种单频周跳的探测方法,即多项式拟合法、载波/伪距组合法和基于灰色预测值的多项式拟合法。通过采用不同的试验方案对这3种方法进行对比分析,表明基于灰色预测值的多项式拟合法比另外两种方法探测能力更强,可靠性更高。而且方法简单,易于在计算机中实现,具有较高的实用性。

| Abstract: | The cycle slip detection is one of the difficulty technology of single -frequency precise point positioning .Polynomial fitting and the comprehensive method and a new polynomial fitting method based on grey prediction model are analyzed here in order to detect quickly , accurately and efficiently the cycle slip .The three methods are compared and analyzed by used the different experiment pro-grams.The results of the experiment show that the new method is stronger than the others and is very reliable in detecting the cycle slip.And the method is simple and easy to implement in a computer with high practicality . |
