摘　　要：针对惯性传感器误差对RTK倾斜测量定位精度的影响问题,设计并实现了一套基于Android平台的GNSS接收机惯性传感器误差校准系统。系统利用蓝牙技术建立与GNSS接收机的通信连接并实现数据的采集与解算,设计基于解析传感器数据的误差改正算法,实现了基于Android平台的误差修正参数的生成与回传,保证了用户在利用惯性传感器辅助接收机工程测量的精度需求。在实际应用中,本系统明显提高了惯导GNSS接收机应用的定位精度,提升了工程测量作业效率,对于惯性传感器在测地型接收机上的应用具有一定的现实意义。Aiming at the influence of inertial sensor error on positioning accuracy of RTK oblique photogrammetry,we designed and implement-ed a set of GNSS receiver inertial sensor error calibration system based on Android platform.By using bluetooth technology to establish a connec-tion to a communications GNSS receiver,the system can realize the collection and calculation of data,in which an error correction algorithm based on the analytical sensor data is designed and implemented to generate the error correction parameters and back it in Android platform,to ensure the accuracy requirement of engineering measurement with inertial sensor assisted receiver.In practical application,the system obviously improves the positioning accuracy of the inertial navigation GNSS receiver,improves the efficiency of engineering measurement,and has certain practical significance for the application of inertial sensor in geodesic receiver.
