基于GPS和INS的测速方法比较分析

摘要

目前常用的测速方法包括测速仪、GPS多普勒观测值测速、INS测速、GPS/INS测速等。文章分析了GPS多普勒测速，INS测速以及GPS/INS测速的基本原理。最后，通过对实测的车载实验数据解算对以上这三种方法进行了详细的比较分析，得出了一些比较有意义的结论。%The current measurement methods commonly used include velocimetry , GPS Doppler observations , INS speed,GPS/INS speed speed etc ..This paper analyzes GPS Doppler velocity measurement ,INS measurement and the basic principle of GPS/INS speed.Finally,through the experimental dataon the measured solution to these three kinds of methods are analyzed comparatively ,get some meaningful conclusions .
