Abstract
The paper develops an earlier proposed approach to the construction of geographically oriented horizon trihedron nonperturbed by inertial accelerations to aid navigation dead reckoning referred to as gyroscopic orientation with correctable pendulum. The proposed scheme is implemented using accelerometer trihedron and only one free gyro in equatorial orientation. Special attention is given to the Schuler filter which not only provides the “absolute” nonperturbality of navigation deadreckoning but also allows formulation of the problem of autonomous estimation of its error to the accuracy determined by the gyro drifts in the steady mode. The problem of occasional correction of “azimuth” heading during in situ observation is also considered.
