MODE OF MEASURING OF THE ANGLE OF A BEARING AND AN ARRANGEMENT FOR ITS EXECUTION Russian patent published in 2007 - IPC G01C19/02 G01S3/78 

FIELD: the invention refers to the field of gyroscopic instrument-making industry, to navigational and stabilization systems.

SUBSTANCE: in the mode of measuring of the angle of a bearing and an arrangement for its execution at determination of pulse duration of a pulse-duration modulated signal its modifications are registered and errors inserted by superimposed noises are reduced. For this the amplitude of pulse of the pulse-duration-modulated signal is additionally determined, and the level of the reference signal is formed equal to half of the amplitude of the pulse-duration- modulated signal providing comparison of the pulse-duration-modulated signal with the reference signal in the middle of the wavefronts where the parameters of the signal is utmost stable. Directly after each of moments t1 or t2 the comparison of the input pulse-duration-modulated signal with the reference signal is prohibited until the moment of achieving by the input pulse-duration-modulated signal of a value level which is larger then the front pulse-duration-modulated signal and less then the rear reference signal on a value prevailing the amplitude meaning of the expected noise, excluding b this the influence of the noises of the front pulses on the comparison result.

EFFECT: increases accuracy of measuring of the angle of the bearing.
