摘要
依据所实现的一种测量航向角的新方法 ,论述磁阻传感器的原理 ,给出了系统数值计算方法 ,分析了系统误差并进行校正。与传统的测量方式 (惯性导航装置、GPS)相比较 ,所提出的航向仪具有重要的优良特性。试验结果显示在捷联状态下 ,用加速度计提供姿态角 ,该系统精度可达到 1°。
This paper focuses on a development of a sensor system measuring heading of a vehicle or plane. The theory of the solid-state magnetic sensor is presented. It also will include the numerical calculation and error compensation. Compared to the two existing measurement methods (INS、GPS), the new method in this paper has superior and important qualities. With an accelerometer-supplying attitude, the experiment result shows that in strapdown condition, the system can provide outputs accurate to one degree or better.
