FIELD: navigation.
SUBSTANCE: invention relates to systems for the orientation and navigation of aircrafts, in particular, to free-of-charge gyroverticals, course curators and navigation systems in which measurement information comes from angular velocity and accelerometer sensors. Way the digital platform is controlled in the freeform gyrovertical includes measuring angular velocities and linear accelerations, converting the increment of the roll and pitch angles from the associated coordinate system to an inertial coordinate system, calculation and compensation of errors in the determination of the angles of roll and pitch with the values of linear acceleration values admissible for controlling the digital platform in the inertial coordinate system and reduction of the digital platform when the values of linear acceleration values in the inertial coordinate system are exceeded in the zone of values of linear acceleration values permissible for controlling the digital platform in the inertial coordinate system. In this case, the linear accelerations in the coupled coordinate system are preliminarily filtered, and the magnitude of the angular rate of reduction of the digital platform from the zone of exceeding the values of linear accelerations admissible for control in the inertial coordinate system in the zone of values of linear acceleration values permissible for controlling the digital platform in an inertial coordinate system is established depending on the magnitude of linear accelerations in the inertial coordinate system and the value of the sign of the inclusion of the reduction of the platform in the zone of linear accelerations admissible for control in the inertial coordinate system, due to which the vibration and noise effects on the gyrovertical are compensated.
EFFECT: increased accuracy of measuring the output angles of the orientation of the object.
