Attitude determination method resisting acceleration interference

The invention relates to the field of equipment precision estimation, in particular to an attitude determination method resisting acceleration interference. According to the designed attitude determination method resisting acceleration interference, a linear acceleration model and a linear acceleration error equation are established to adapt to the linear acceleration of equipment in real time, and the acceleration interference resisting attitude of the equipment is determined. Compared with a traditional attitude determination method, by means of the attitude determination method, adaptive online real-time estimation of the linear acceleration of a carrier can be achieved, interference of the linear acceleration of the carrier is effectively weakened, and the attitude estimation precision and stability are improved.
