摘　　要：海岸线地理环境特殊,讨论海岸线测量的特点,提出集成GMS无线电数据链,进行摩托化海岸线DGPS实时动态测量新方法和技术体系。分折了卫星定位误差、无线电数据链误差和用户测量平台稳定性误差影响。特别针对GMS无线电数据链可靠性和测杆摇摆与铅垂对定位精度的特殊影响。结出了海岸线DGPS实时动态测量误差影响的估计模型。In this paper, characteristic of the coastline survey is discussed because it is a special environment. A new techno-systern and the method are put forward based on GPS real time kinematics surveying for the motorization coastline survey when it is integrated with the GMS data chain. It analyzes the error of the Sea location-satellite, electromagnetic wave transmit error and the measure flat roof stability error. Aiming at the peculiarity influencing of the dependability on GMS data chain and shank swing, an estimation model of error influencing on the coastline GPS real time kinematics surveying is proposed.
