摘要
与陀螺仪相比,在车辆航位推算系统中采用磁阻传感器具有较高的性价比。本文阐述了航位推算以及磁阻传感器的工作原理,详细分析了磁阻传感器的误差,提出了相应的误差修正方法,给出了一个用于航向角推算的实用电路。
In dead reckoning for vehicles, the magnetic sens or is better than gyroscope in perfor- mance and price ratio. This paper intro duces the principle of magnetic sensor and dead reckoning, analyzes magnetic sen sor s error and corresponding compensation method. Finally, a circuit of dead re ckoning for vehicle is presented.
