Design and Realization of Silicon MEMS-Based Micro Magnetic Compass for Mini-UAV

摘要：

High cost,low response frequency and dynamic time delay are general problems in most of the existing micro magnetic compass(MMc).According to the characteristic of mini-UAV navigation and control system,this paper presents a silicon MEMS-based integrated MMC,determining attitude by both accelerometers and anisotropic magneto resistance(AMR) sensors through estimating the mini-UAV state utilizing the Z-direction gyroscope.On the other hand.the magnetic disturbance around the MMC is calibrated.The experiments shOW that this MMC,wjth good collective performance,0.5° heading accuracy.1/5 cost and 50Hz response frequency,is able to meet the requirements of extraordinary precision,low cost and real time communication
