摘要
描述了一种低成本的GPS/INS组合导航系统,经过理论推导得到了系统具体的实现方法,并通过市场上大量使用的低成本GPS模块和MEMS陀螺和加速度计实现了该系统。实际路测数据结果显示,该系统基本达到了理论预期。
To lower the computational requirement for embedded processor,sequential measurement update algorithm is implemented.The result of road test in urban canyon verified the algorithm and architecture.This navigation system can estimate vehicle＇s position,velocity and heading even when autonomous GPS receiver fails to work.The proposed application includes high-performance car navigation system,altitude estimation system,etc.Another purpose of this project is to provide a altitude reference for ultra-tightly coupled navigation system based on software radio（SDR） GNSS receiver.
