摘　　要：提出一种单频GPS载波相位周跳探测、修复方法,采用载波相位变化率探测周跳,并记录周跳发生的开始时间和结束时间,进而利用切比雪夫多项式修复周跳。介绍了该算法的数学模型,给出了具体实施步骤,并用算例验证了算法的有效性与可靠性。A new method is proposed for detecting and repairing cycle slips in GPS navigation based on the single frequency observations. Carrier phase rate is used to detect cycle slips, and record the starting time and the closing time of cycle slips. Then Chebyshev polynomial is used to repair cycle slips. The mathematical model of the method is introduced in this paper. The concrete imple- mentation steps are presented. The reliability and validity of the method are testified by an example.
