In order to improve the precision of GPS navigation and positioning the cycle-slip detection in GPS carrier phase needs to be done and repaired.It analyzes several algorithms of GPS carrier phase cycleslip detection and recovery,and compares briefly the advantages with disadvantages.The polynomial fitting is chozen which is easy to be produced by computer language as the mathematical model to pretreat the carrier phase.The procedures of single frequency GPS cycle-slip detection and correction are accomplished by combining with the VB language.The effect of this method is analyzed and verified with sample data.
