摘要
针对在城市复杂环境下弱信号定位测姿精度低的问题,该文将实时动态差分技术与惯性导航系统/全球导航卫星系统深耦合接收机定位测姿系统进行结合,提出了一种基于惯性导航系统/全球导航卫星系统/实时动态差分技术三组合的高精度定位测姿的方法。该文对惯性导航系统/全球导航卫星系统/实时动态差分技术三组合高精度定位定姿方法涉及到的核心技术进行介绍,详细分析了影响定位测姿精度误差因素,并将该方法应用于新一代测绘车上,通过理论分析和实际跑车实验证明了该方法具有较高的精度和适用性。
Aiming at the problem that the position measurement accuracy of weak signals is low in urban complex environment,this paper combined real-time kinematic（RTK）technology with inertial navigation system（INS）/global navigation satellite system（GNSS）deep coupled receiver pose-positioning measurement system,and put forward a high-precision position measurement method which combined INS/GNSS/RTK.Core technologies involved in INS/GNSS RTK combination were introduced,and factors influencing the pose-positioning measurement accuracy were analyzed,the article applied the method in the new generation of surveying and mapping vehicle,through theoretical analysis and actual sports car experiment,it showed that the method had high precision and applicability.
