The invention discloses a method for realizing orthogonal control of a cup-shaped gyroscope. The method comprises the following steps: 1, acquiring 48-terminal electrode signals of a charged cup-shaped gyroscope; 2, filtering clutter signals in the 48-terminal electrode signals by using a frequency selective network, and selecting effective signals related to the resonant frequency of a cup-shapedgyroscope body; 3, demodulating the effective signals through a first reference signal to obtain a first frequency difference signal; 4, carrying out filtering correction on the first frequency difference signal by using a filtering correction circuit to obtain a second frequency difference signal; and 5, modulating the second frequency difference signal by using a second reference signal to realize orthogonal control. The method improves the orthogonal drift phenomenon of the gyroscope and improves the precision of the gyroscope.
