首发时间:2008-10-15
摘要:研究了伪距/载波组合和电离层残差探测和修复周跳。利用伪距/载波组合探测和修复6~8周以上的周跳,对修复后的数据进行电离层残差探测,分离发生周跳历元的电离层残差跳变量,得到8周以内的周跳量并修复,实现了30s以内采样间隔任意整周周跳的探测和修复。实验证明此方法是可行的。

Research on Method of Cycle Slips Detection and Reparation for Dual Frequency GPS Data
Abstract:Detecting and repairing cycle slips using the combination method of pseudorange –phase combination and remaining ionospheric errors were studied in this paper. Pseudorange –phase combination was used to detect and repair more than 6~8 cycle slips, remaining ionospheric errors was used to detect and separate less than 8 cycle slips after repairing . The detecting and repairing arbitrary integer cycle slips within 30s sampling interval had been realized.The credibility of the combination method was proved by experiments.
Keywords: cycle slip pseudorange–phase combination remaining ionospheric error sampling interval
