Abstract
To solve the problem of low observability of IMU (Inertial Measurement Unit) error coefficient deviation, the random direction search method was adopted. Aiming at the problem of search results´ divergence in case of one-dimensional target function, six-dimensional target function combined of velocity and location was proposed, and the search effect of error coefficient deviation was enhanced.
