RTK终端实时动态检测技术研究

Research on real-time dynamic detecting technologies of RTK terminal equipment

传统的RTK(实时动态定位)终端检测采用静态基线数据解算的方法,该检测方法与RTK终端实际动态应用场景不符,无法满足动态检测需要。通过研制高精度的车载导航基准设备和开发车载动态检测软件,同时解决车载设备数据的同步问题,提出基于车载移动平台的实时动态RTK终端检测技术。车载基准设备和待检测设备可以动态解算同源数据并实时上发结果,软件处理中心通过比对处理解算结果,对待检测设备进行检测评价。实验结果表明,设计所得的车载系统可稳定运行,并实现动态检测过程。同时,在良好的观测条件下,检测精度平面方向达到1cm,高程方向达到2cm,实现高精度实时动态检测的目的。

The traditional method of detecting real-time kinematic（RTK）equipment adopts static baseline solution,which doesn＇t conform to the actual dynamic application and meet the needs of dynamic detecting.Through the development of high-precision standard equipment and dynamic detecting software,it has proposed a real-time and dynamic detecting method based on in-vehicle mobile platform with solving the data synchronization.The core idea of this method is that the software processing center evaluates the testing equipment by comparing its positioning results with standard equip＇s.Experimental results show that the detecting system can stably run and the detecting accuracy can reach 1cm on horizontal direction and 2cm on vertical direction,which server the purpose of high-precision real-time dynamic detecting.
