| 摘 要： | 针对BDS/GPS双差组合数据解算需要考虑观测数据周跳探测与周跳修复能力的问题,研究组合观测值周跳检测量公式模型,给出一种能够有效探测并修复周跳的BDS/GPS双频三差组合周跳探测与修复方法。实验数据结果表明,该方法利用三差后的无电离层组合残差和双频载波残差平均值做为周跳检测量从而能够有效探测出GPS卫星和北斗的GEO、MEO、IGSO卫星观测值中存在的周跳并修复,从而为BDS/GPS双差网解提供高质量、高可靠性的观测数据。

| Abstract: | For the BDS/GPS double-difference combination data solution,the problem of double-difference combined data cycle slip detection and cycle slip repair ability needs to be considered.The formula model of combined observation cycle slip detection is studied,and a kind of cycle slip can be effectively detected and repaired.BDS/GPS dual-frequency three-difference combination cycle slip detection and repair method are proposed.The experimental data show that the method can effectively detect the presence of GPS satellites and Beidou GEO,MEO and IGSO satellite observations by using the three-difference ionospheric combined residual and the dual-frequency carrier residual mean as the cycle slip detection variable.The method can provide high-quality,high-reliability observation data for BDS/GPS double-difference network solution processing. |
