(-180°≤φ<-135°),
(-135°≤φ≤-45°),
(-45°<φ<45°),
(45°≤φ≤135°),
(135°<φ<180°),
где U1, U2 - первая и вторая квадратурные составляющие после квадратурной обработки выходного сигнала ВОГ.2. The method according to p. 1, characterized in that the phase detection of the output signal of the VOG at the speed; FOG is produced by quadrature processing, using two control signals whose frequencies are equal to the rotational speed, their phases having a shift of 90 ° relative to each other are controlled relative to the coordinate system in which measurements are made, and the phase φ of the FOG output signal corresponding to the azimuth is determined according to the formulas:
(-180 ° ≤φ <-135 ° ),
(-135 ° ≤φ≤-45 ° ),
(-45 ° <φ <45 ° ),
(45 ° ≤φ≤135 ° ),
(135 ° <φ <180 ° ),
where U 1 , U 2 - the first and second quadrature components after quadrature processing of the VOG output signal.
