摘　　要：为了对比分析海洋工程导航定位领域北斗二号设备与全球定位系统(GPS)设备之间的导航定位性能,首先在陆地对北斗二号设备开展了系统兼容性及稳定性测试,然后开展海上动态试验,以GPS坐标为基准,对北斗系统的定位精度进行了比对分析。结果表明:该北斗二号设备和GPS设备在海上动态试验中测得的船艏向数据高度一致;北斗设备与GPS设备横、纵轴定位误差均在亚米范围内。在对精度要求亚米级的实际海洋工程中,北斗二号设备已具备代替GPS设备进行导航定位的能力。In order to compare and analyze the navigation and positioning performance between BeiDou navigation satellite system(BDS)-2 equipment and global positioning system(GPS)equipment in the field of ocean engineering navigation and positioning,the system compatibility and stability tests were first carried out on the BDS-2 equipment on land,and then the dynamic tests at sea were carried out.Based on GPS coordinates,the positioning accuracy of the Beidou system is compared and analyzed.The results show that the ship’s heading data measured by the BDS-2 equipment and the GPS equipment in the dynamic test at sea are highly consistent;the positioning error of the BDS-2 equipment and the GPS equipment is within the sub-meter range.In actual ocean engineering that requires sub-meter-level positioning accuracy,BDS-2 equipment has the ability to replace GPS equipment for navigation and positioning.
