Abstract The micro-electro-mechanical systems (MEMS) accelerometer is one of the most important part in inertial motion tracking system, which can be used to obtain the location information movement. In order to exactly location, it is necessary to calibrate its error. According to the sources of the errors and their generation mechanisms, the error model is established.By analyzing the error model, it proposes a method based on AFSA to correct the accelerometer error, and then it will be compared with the six-position testing method. This method can reduce the errors and improve the measurement accuracy of angle in a degree. And the outputs of the micro-electro-mechanical, accelerometer can reflect their true values.
