FIELD: radio engineering, communication.
SUBSTANCE: radio navigation signals from n spacecraft are received by at least two spaced-apart antennae of a receiving antenna device, mounted directly on the rotating part of an object. Coordinates of points on the path of rotation of the antennae are measured. Two incremental vectors are calculated at three consecutively measured coordinates of the antennae. The direction of the axis of rotation is determined from the normal vector of the plane of rotation and the magnitude of the vector of angular velocity of the object is also determined.
EFFECT: determining orientation, monitoring and controlling a rotating object located on both a stabilised or a non-stabilised platform in the horizontal plane, which increases accuracy of a radar system and reduces the load on a rotary mechanism by correcting the axis of rotation.
