摘要
为了准确地对车辆进行定位,实现导航功能,将两种常用的导航定位技术GPS定位导航技术与惯性导航技术进行组合,介绍了INS/GPS组合导航系统的仿真方案。因车载组合导航系统对精度的要求不是很高,采用低成本的机械陀螺和加速度计作为惯性导航系统的测量器件。INS/GPS组合导航系统采用位置和速度组合模式,分别给出纯INS,纯GPS,组合导航系统的位置误差比较。结果分析表明,组合导航系统精度高于INS和GPS分别独立工作时的精度。
In order to locate the vehicle accurately and realize the function of navigation,the two kinds of commonly used navigating and positioning technology—the GPS and the inertial navigation technology are combined.A way of simulation for the INS/GPS integration navigation system is introduced.The navigation system requirement for precision is not high,so the low-cost gyroscopes and accelerometers can be used as the inertial navigation system measurement devices.The INS/GPS navigation system uses the position an...
