【摘要】：针对接收机持续性地测量载波相位值时会出现周跳现象从而降低数据处理精度的问题,提出一种改进GPS的组合周跳探测与修复方法。通过分析周跳发生的原由,对电离层残差法进行了分析,指出了它的不足。采用载波观测值线性拟合的方法进行辅助探测的改进,对周跳进行修复,并通过实例分析进行验证。仿真结果表明:该方法能较好地弥补电离层残差法的不足,并能有效地探测与修复。
[Abstract]:For the receiver to continuously measure the carrier phase value will appear when the jump phenomenon so as to reduce the accuracy of the data processing problems, and put forward an improved GPS combined cycle slip detection and restoration methods. Through the analysis of the reason of cycle slips, ionospheric residual method is analyzed, pointing out its shortcomings. The carrier observation method linear fitting of improved auxiliary detection, jump on the week to repair, and is verified by the example analysis. The simulation results show that the method can effectively compensate for the lack of ionospheric residual method, and can effectively detect and repair.

【正文快照】： 0引言接收机持续性地测量载波相位值时,由于某些因素使得整周计数出现问题,测得的相位观测值相比准确值出现几个整数周的跳跃,称为周跳[1]。在持续性地测量载波相位值时,若接收机对某卫星的载波相位观测值在某一历元发生周跳,则将会从该历元的该卫星后续的载波相位观测值中加
