摘要
航位推算系统是城市车载导航定位系统的重要组成部分,其中陀螺仪、里程计等传感器参数标定影响到系统定位精度。介绍了利用GPS和电子地图数据库信息进行传感器参数在线标定的方法。在香港特区的大量现场跑车实验表明,该方法有利于提高航位推算系统的精度及稳定性,从而使得车栽导航系统精度满足设计要求。
Dead reckoning system（DRS） is an important part of integrated in-vehicle navigation and positioning system in urban. The positioning precision is affected by the parameters of gyroscope and odometer. A kind of on-line modification of sensor parameters with GPS and digital map database in DRS is studied. A field test in HK is performed, and the result shows that the DRS accuracy and stability are improved, and then the accuracy of the integrated navigation system can reach the design.
