Title：CALIBRATING METHOD FOR ELECTRONIC COMPASSElectronic compass is an electronic compass by measuring the Earths magnetic field to achieve directional navigation device, it is an important navigational tool that can provide real-time data objects heading and attitude, and has a small size, low cost, fast response , no accumulated error, etc., are widely used in mobile robots, vehicles, aircraft and other orientation subsystem; However, due to the electronic compass is based on magnetic principles calculations magnetic bearings, their work environment, in addition to other external magnetic field Earths magnetic field will inevitably affect the output of the electronic compass, resulting in errors affect measurement accuracy. Therefore, how to reduce outside interference precision of its output is engineering applications must be addressed.Electronic compass the existing literature has proposed several possible compass error compensation method. Yuen Chee Wing paper, three-axis magnetic heading sensors full attitude error compensation proposed compass error into quadrature error, zero and sensitivity errors were compensated, high compensation accuracy of the method, but in the compensation process requires non-magnetic turntable , but also the computer automatically when the measured rotation compass X and Y-axis sensor output maximum, minimum, the calibration process is complex and requires high equipment; HIGHWAY AND TRANSPORTATION Wang Jiaxin paper Development of high-precision electronic compass and Shao Tingting, ROCKETS paper electronic compass tilt and Luo slip compensation algorithm research, the least square method to compensate for the electronic compass, the method requires Compass 0 ° ~ 360 ° rotation average sampling, operation is relatively cumbersome and The amount of data samples of different sizes will have a greater impact fitting result, the amount of data is too small, the compensation effect is not good, too much data can cause performance degr
