High latitude geocompass

An autonomous navigation system for orientation on the surface, under water, and under the surface of the Earth is considered. The passive location of the Earths rotation axis is carried out by the vector of the geocompasss radiation pattern during angular scanning of space. A solid-state design of a geocompass is proposed and implemented, in which the deformations of the medium under the action of an alternating acoustic field and field of the Earths Coriolis acceleration form the diagram vector. Experimental space scanning confirms the formation of a direction vector coinciding with the orthogonal to the Earths rotation axis, which makes it possible to qualify the device as a geocompass oriented at high latitudes to the geographic pole.
