Abstract
Among the factors affecting the system error of digital magnetometer
the contributor comes from the precision variance of the production of the digital magnetometer and installation.Through a careful analysis and calculation of system error of digital magnetometer
a simple and effective method for system error compensation is presented which is the 8-position calibrating method.Experiments are done to verify the method.The result shows that the system error of digital magnetometer can be compensated and the heading measure precision can be improved validly by using this method.
