Device for determining location information and inertial primary references for an aircraft

The device (100) has a measurement unit (110) for determination of location information of a commercial aircraft. The measurement unit includes a data measurement unit (111) for measurement of radio navigation data of aircraft. The measurement unit has a consolidation unit (112) for consolidation of radio navigation data of aircraft. A calculation unit (113) calculates location parameters of a commercial aircraft from the consolidated radio navigation data. A comparison unit compares a set of comparison results for detection of average comparison value and for stopping the consolidation unit.
