The paper presents a group-theoretical
approach to the problems of metrological support for electrodynamic seismic
receivers of accelerations. Symmetry groups in the equation of motion of
the seismic receiver sensing element were found: translation (transfer) group,
nonuniform extension (dimensional scaling) group, and the Galilei group.
The proposed technique was developed to define parameters of the CBU-1 seismicreceiver
of vertical accelerations using a vibrobench certified by the Gosstandard
(National Standards Agency) authorities on state reference standards.
