Abstract
The paper considers the development of the approach proposed earlier by the author to ensure the imperturbability of dead reckoning, based on the construction of a single-channel inertial vertical using a trihedron of accelerometers and a single free gyroscope. In order to improve the accuracy of instantaneous orientation angles required to solve vehicle control problems, a method is proposed that uses the data from the inertial vertical channel, as well as the difference in heading values generated with the use of information from the free gyro and the “budget” MEMS inertial unit, and lag readings processed in accordance with the principle of gyroscopic orientation with a controllable pendulum. The simulation results are presented, which confirm the effectiveness of the proposed method.
