In inertial navigation system

some traditional calibration methods of accelerator mainly rely on turntable

other methods without the support of turntable have less accuracy.Therefore

this paper presents a high-accuracy calibration method of accelerator without the support of turntable.It only needs 12 static output data of accelerator to calibrate the bias

scale factor and misalignment.Experiment results indicate that this method has higher accuracy compared with traditional calibration method without the support of turntable.
