MAGNETIC COMPASS Russian patent published in 2008 - IPC G01C17/02 

FIELD: invention refers to field of navigational instrument making.

SUBSTANCE: arrangement has magnetic sensitive element, binnacle and a system of even quantity of bars out of soft magnetic iron forming concentrator of induction of magnetic field. Bars of soft magnetic iron are fixed on binnacle and placed in horizontal plane at level of magnetic sensitive element in radial direction to symmetry of magnetic system of magnetic sensitive element on equal distances from it. At that angles between longitudinal axles of symmetry of neighboring bars are equal between themselves.

EFFECT: improves operational characteristics of arrangement, expands functional possibilities.
