Abstract

Keywords

We employ direct numerical simulation to investigate the

phenomenon of drift in a hemispherical resonator gyro-

scope, caused by non-homogeneous density distribution.

We described a rotating cylindrical resonator by a system

of ordinary differential equations with constant coef-

ficients and found the solution to the system using a

matrix exponential. We provide examples that illustrate

the drift phenomenon for various values assumed by the

non-homogeneity parameter of the density distribution
