周跳探测法在北斗精度定位中的应用研究

介绍了北斗卫星导航系统的发展现状以及北斗卫星的组成，运用载波相位测量卫星信号，得出卫星观测过程中存在卫星周跳现象。在此之后，解析了该卫星导航精度定位的误差来源，一共能够分成三种不同的类型，分别指的是：与该卫星自身有关联的误差；与其信号传播路径有关联的误差；与接收机以及测站有关联的误差。在此步骤结束之后，剖析了周跳的定义与特性，除此之外也分析了周跳对精密定位带来的影响。最终，通过仿真方法得到了有无周跳状况下的高次差法的影响。

Research on the Application of Cycle Slip Detection in Beidou Precision Positioning

This article introduces the development status of Beidou satellite navigation system and the composition of Beidou satellites. Using carrier phase to measure satellite signals, it is concluded that there is a satellite cycle slip phenomenon during satellite observation. Then further analyze the sources of errors in Beidou satellite navigation precision positioning, which can be divided into the following three categories: errors related to Beidou satellites themselves, errors related to satellite signal propagation paths, and errors related to receivers and stations. Then analyze the definition and characteristics of cycle slip and the effect of cycle slip on precision positioning. Finally, the influence of high order difference method with or without cycle slip is obtained by simulation method.
