摘要
针对接收机捕捉卫星信号时出现中断(失锁)现象,提出了一种基于双差观测值高次差法的周跳探测和基于最小二乘多项式法的周跳修复方法。研究了周跳探测和修复过程,改进了高次差法和多项式法,构建了新型周跳处理模型。结合实例和通过仿真运算分析,表明双差观测值法能有效弥补普通高次差法对小周跳探测的不足,最小二乘多项式推估法能有效修复小周跳。
In view of the interruption(losing the lock)phenomenon when the receiver captures satellite signals,a cycle slip detection based on the high-order difference method of double-difference observations and a cycle slip repair method based on the least-squares polynomial method are proposed.In this paper,the cycle jump detection and repair process is studied,and the high-order difference method and polynomial method are improved,and a new type of cycle-jump processing model is constructed.Combined with examples and analysis through simulation,it is shown that the double-difference observation method can effectively compensate for the deficiency of ordinary highorder difference method for detection of small cycle jumps,and the least-squares polynomial estimation method can effectively repair small cycle jumps.
