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
