Due to the impact of the vehicle engine jitter, unevenly inflated tires and people moving, the attitude initial alignment accuracy is not high and the repetition is poor. The author proposed the two‐channel ten state variable error model for land vehicle application, the system for error equation and measurement equation are established to solve the initial alignment problem of strapdown inertial navigation system, and the simulation experiment and the initial comparison of the system static base are carried out, the calculation method of strapdown attitude is optimised and the initial alignment problem in complex environment is solved, which provides a reference for fast initial alignment of the vehicle strapdown inertial navigation system.
