摘　　要：针对海洋平台在单点系泊作用下运动轨迹的监测问题,研制了一套DGPS海洋平台水平运动轨迹测量装置。该装置利用GPS实时测量海洋平台的定位位置,通过自建基准站提供差分改正数据,移动站接收并解析该差分数据提高传统GPS接收机的定位精度,两者构建DGPS测量系统,动态描绘海洋平台的运动轨迹。通过地面小车运动模拟海洋平台的水平运动,对该DGPS测量系统进行各项静态和动态性能的实际测试,结果表明,其动态跟踪效果完全能够满足海洋平台运动轨迹测量的需要。Aiming at the requirement of the monitoring of offshore platforms in the role of single point mooring trajectory,this paper develops a DGPS marine platform trajectory measuring device.The device makes use of GPS to real-time measure the positioning location of the offshore platform,which can supply the DGPS measurement differential correction data by building self-build station and receive and resolve the differential data by the mobile stations to improve the positioning accuracy of traditional GPS receiver and dynamically depict the trajectory of the offshore platform.The DGPS measurement system is tested through the moving trolley on the ground to simulate the marine horizontal movement of the platform,and results show that the effect of dynamic tracking is fully able to meet the needs of the offshore platform trajectory measurements.
