FIELD: measurement equipment.
SUBSTANCE: unit of orientation of navigation instrumentation relates to aviation equipment, namely, to units of orientation of airplanes and helicopters. The device differs by the fact that it additionally contains the second inertial measurement unit, the first and second buffers, the first and second isolation units connected with their inlets to outlets of the first and second inertial measurement units, accordingly, and with outlets - to an inlet of a magnetometer, the outlet of which via the first and second buffers is connected to the inlets of the first and second inertial measurement units, accordingly. The proposed device is used in a heading and vertical sensor.
EFFECT: increased reliability and accuracy of airplanes and helicopters piloting.
