MODE OF MEASURING OF THE ANGLE OF A BEARING AND AN ARRANGEMENT FOR ITS REALIZATION Russian patent published in 2008 - IPC G01C19/02 G01S3/78 

FIELD: the invention refers to gyroscopic devices used in quality of a sensor of the angle of the bearing on guided rockets, in systems of navigation and stabilization.

SUBSTANCE: the mode of measuring of the angle of a bearing is in that the a gyroscopic device rotor is speeded up and uncaged, an electric pulse-duration modulated signal the duration of whose impulse is linearly connected with the measured angle of the bearing with the coefficient of proportionality is worked up, current duration τ and the period Tp of sequence of impulses of the pulse-duration modulated signal are measured. At that the duration τ_o and the period Tp_o of the sequence of the impulses of the pulse-duration modulated signal at the angle of the bearing δφ=0 are preliminary defined and stored, the ratio t_o/Tp_o is defined and stored_, at measuring the current angle of the bearing the ratio of the duration of the impulse of the pulse-duration modulated signal to its period τ/Tp is defined and the angle of the bearing is determined. The arrangement for measuring of the angle of a bearing has a gyroscopic device with a photo optical sensor of the angle, a time device, a register, a calculator, a commutator, and also an electronic apparatus block.

EFFECT: the invention allows increase accuracy of measuring of the angle of a bearing due to reducing the influence of the deflections of the period of rotating of the rotor of the gyroscopic device and expand possibility of the usage of gyroscopic devices with unstable rotating frequency of the rotor.
