三维磁感式电子罗盘的研制与标定
Development and Calibration of Three-dimensional Magneto-Inductive Electronic Compass
【摘要】 为了实现精确的地磁导航,使用PNI磁感传感器和VTI倾角传感器研制了三维磁感式电子罗盘。同时运用最小二乘法研究了三维电子罗盘的标定算法,并通过试验证明:经过标定的电子罗盘性能良好。
【Abstract】 In order to achieve precise magnetic navigation,PNI Corporation’s magneto-inductive(MI)sensors and VTI Corporation’s inclinometer were used to develop the three-dimensional electronic compass.The least squares method was used to explore calibration algorithm of the compass,and experiments show that the calibrated electronic compass has good performance.
