Abstract Here, a modified model based on the nonlinear least square fitting method was proposed for solving the problem of initial misalignment angle caused by installation error in accelerometer gravimetric calibration. Verification tests were conducted for the modified model using a gravimetric static calibration device. The test results indicated that the modified model can be used to correctly calibrate parameters of the initial misalignment angle to reduce the effect of installation error on the calibrated result in accelerometer gravimetric calibration.

Key words： accelerometer static sensitivity calibration by Earth’s gravitation installation error nonlinear least square method
