| 摘 要： | 介绍了高精度GPS动态定位的基本原理，提出了一种在动态定位过程中周跳修复的方法，此法计算简单，组合数少，计算速度较快，可用于实时动态定位，从而可以大大减少动态定位过程中重新进行初始化的次数,根据所编制的软件，对静态观测数据进行动态定位的解算，并对沪宁高速公路动态定位数据解算结果与常规测量进行了比较分析，结果表明平面和高程都达到了厘米级精度，表明所提出的周跳修复方法的正确性

| Abstract: | The basic principle on high - precision GPS kinematic positioning is briefly introduced and an algorithm for cycle slips recovery in kinematic GPS positioning is proposed which can make combinations fewer, computation simpler and quicker. Thus,it can be applied in real kinematic GPS positioning.The result and analysis from a static GPS observation and from a real GPS kinematic positioning observation in Huning Highway, which are compared with those from normal surveying, indicate that centimeter level result has reached both in horizontal and vertical. |
