FIELD: physics; navigation. ^ SUBSTANCE: invention relates to instrument making particularly to aircraft navigation devices. To achieve the given result, the device includes a unit of inertial initial information sensors, a three-component magnetometre, an analogue-to-digital converter (ADC), a computer, a reference voltage source, an analogue inverter, a signaling device, three control channels, a protection device and an analogue switch. The device also includes a test-control of the magnetometre by applying direct voltage across its input from the reference voltage source. The magnetometre changes its output signal, from the value of which working capacity of the device is determined. ^ EFFECT: increased reliability. ^ 1 dwg |
