| 摘 要： | 周跳的探测与修复，特别是小周跳的探测是实现GPS高精度实时定位的关键技术基础之一。分析了非差相位观测值线性组合模式，比较了几种周跳修复的方法，得出宽巷和电离层组合方法更适用于精密单点定位中双频GPS数据的周跳探测和修复。通过实例分析，证明该方法能够有效地探测并修复周跳。

| Abstract: | Detection and reparation for cycle slips,especially detecting small cycle slips is one of key technologies which achieve high precise positioning in real time.The paper analysis the linear combination model of undifferenced phase observation;compares several methods of detection and reparation for cycle slips,resultingly,the combination with widelane and ionospheric method is more fit for precise point positioning of dual-frequency GPS data.It proves this method effectively by instance. |
