载波相位差分技术在车载导航中的应用

Application of Carrier Phase Difference Technology in Vehicle Navigation

基于现阶段用户对高精度定位的需要,文章分析了三种常见的卫星导航定位方法。对差分技术进行了重点研究。在对比分析之后,发现载波相位差分定位精度可以达到厘米级别的定位。将其运用在车载导航终端设备,开展试验后,对数据进行比对,得到车载导航的定位精度达到米级别,完全可以满足用户对高精度定位的需求,具有重大的应用价值。

Based on the needs of high-precision positioning by users at this stage, this paper analyzes three common methods of satellite navigation and positioning focus on the differential technology. After the comparative analysis, it was found that the carrier phase differential positioning accuracy can reach the centimeter level of positioning. It is applied to the in-vehicle navigation terminal equipment, and after the test, the data is compared, and the positioning accuracy of the in-vehicle navigation is also in the centimeter level, which can fully satisfy the user’s demand for high-precision positioning, and has great application value.
