Abstract
The equations for the rotor motion of a strapdown electrostatically suspended gyroscope (ESG) in the polar orientation at self-rotation of the ESG housing about the axis aligned in the direction close to the celestial axis are considered. Analytical solutions of motion equations using a deterministic model of the ESG drift are given. The effects of self-rotation on gyro motion parameters and predicted gyro drift errors in the projections on the axes of the equatorial coordinate system are studied. The obtained solutions are shown to be in agreement with the experimental data.
