Embodiment Construction
[0014] As shown in Fig. 1, 2, concrete method of the present invention is as follows:
[0015] 1. Establish the overall error model of the IMU, including the angular velocity channel error model and the acceleration channel error model of the IMU, as shown in formulas (1)-(3) and formulas (4)-(6) respectively.
[0016] Angular velocity channel error model:
[0017] ω ‾ x = K x 1 ω x + K x 2 ω x 2 + M xy ω y + M xz ω z + D x + D xx f ...
