The article considers the damping circuit for strapdown inertial navigation system with using smoothing filters and non-linear elements in channels of the integral correction on pitch and roll. Working capacity of the given circuit is tested by method of mathematical modeling of the functioning the navigation system in quaternion parameters. Accuracy of the estimation orientation and navigation parameters are increased in 3–5 times.
