Abstract
This paper provides a method for the overall calibration of the accelerometer combined error model coefficients. The calibration of the accelerometer error coefficients is achieved by using the Norm-observation method. It is important to achieve the calibration of the quadratic coefficient of the accelerometer. First, the Tylor series is used to expand the solution of the acceleration model, the nonlinear equations to be solved are obtained by using the least square method and Norm-observation method. Finally using 1stOpt platform of global optimization algorithm for the solution of equations for quadratic order coefficient, scale factor and zero bias. A 12-position method is designed to calibrate the accelerometer combination, the effectiveness of the method is verified by simulation.
