【摘要】 随着我国"北斗"卫星导航系统的发展,"北斗"精密相对定位的应用市场日益拓展。在动态对动态环境中,将基准站与移动站分别设在不同的车辆载体上,验证了"北斗"实时动态相对定位的精度。平台跑车和省道跑车结果显示水平相对定位误差和天向相对定位误差都在厘米级,表明"北斗"系统性能完全满足高精度应用的需求,能替代相应应用领域的全球定位系统(GPS)。更多还原

【Abstract】 With the development of Beidou navigation satellite system( BDS),the BDS precise relative positioning will have a good application prospect. By setting the base station and the rover station in different moving cars,the accuracy of BDS real time dynamic relative positioning is verified. Test results show that,on both open platform and provincial road,the standard deviation of relative positioning error is within the centimeter both in horizontal and vertical directions. The results indicate the BDS meets the needs of high-accuracy relative positioning and can replace the global positioning system( GPS) in corresponding fields.更多还原
