FIELD: navigation.
SUBSTANCE: hydrodynamic gyroscope comprises housing, rotor with spherical controlled space partially filled with fluid, spherical float mounted inside the space and provided with the permanent ring magnet, cylindrical magnetic circuit, controlled magnetic device, signaling coil, electric motor, and hollow cylindrical frame. The hollow cylindrical frame is made of an electrically insulating material and provided with a ring groove on its outer side. The frame is set inside the cylindrical magnetic circuit for permitting the ring groove to be symmetrical with respect to the equatorial plane of the float. The ring signaling winding is set in the ring groove of the frame and is made of a multi-row winding with even number of rows. Each turn of the winding tightly abuts the adjacent turns. The permanent ring magnet is made of a magnetically rigid alloy based on Fe-Cr-Co.
EFFECT: enhanced precision.
