摘要

基于陀螺仪的寻北器具有抗局地磁场畸变的鲁棒性和电磁传输的独立性,是目前常用的寻北器。在本文中,我们提出了一个易于使用,紧凑,便携,独立,基于一个MEMS陀螺仪的寻北器。Maytagging算法允许使用便宜的步进电机。集成的内部开发的音叉MEMS陀螺仪提供足够低的噪音和漂移,以确定在50.8度的纬度下,在不到10分钟的时间内北航向下降到1度的偏差,而无需额外的信号转换电子设备。

Compact Standalone North-finding Device based on MEMS Gyroscope and Maytagging
North-finders based on gyroscopes are commonly used because of their robustness against local Earth magnetic field distortion and independence of electromagnetic transmission. In this paper, we present an easy to use, compact, transportable, standalone, north-finder based on one MEMS gyroscope. The Maytagging algorithm allows the use of an inexpensive stepper motor. The integrated in-house developed tuning fork MEMS gyroscopes offer low enough noise and drift to determine north heading down to 1 degree of deviation in less than 10 minutes at a latitude of 50.8 degrees without additional signal conversion electronics.
