To Analyze and Compensate Errors of Magnetic Compass
Luo Jin · 2007
Magnetic Compass can be widely used in civilian and m il itary fields,the key technology of magnetic compass is error compensation.This paper analyses errors of magnetic compass firstly,and then,presents a new com pensation algorithm based on BP network which is utilized to compensate magnetic deviation mostly.Further,a three layers BP network which input is measured hea ding and output is compensated heading is set up.The result shows this compens ation algorithm can compensate magnetic deviation preferably and the mean varian ce of heading error is only 0.392 55 after compensation.
