The invention discloses a radio navigation parameter simulation method considering navigation station and tuning information. The method comprises the following steps: acquiring the current aircraft position information; acquiring radio navigation tuning information; querying an onboard navigation database according to the current aircraft position information, and thus obtaining alternative radio navigation station information; querying the alternative radio navigation station information according to the current radio navigation tuning information of the aircraft, and thus obtaining the tuned radio navigation station information; realizing radio navigation parameter simulation according to the current aircraft position information and the tuned radio navigation station information by utilizing a radio navigation parameter calculation method. The problems that the actual navigation station information is not considered and radio navigation parameter simulation cannot be performed according to tuning information of a flight management system in the conventional radio navigation parameter simulation method are solved, and economic and high-quality radio navigation simulation data is provided for test and verification of radio navigation integrated management of the flight management system.
Description
technical field [0001] The invention belongs to the technical field of radio navigation system simulation. Background technique [0002] The flight management system (FMS) is the core component of the current airborne avionics system, which has functions such as multi-sensor integrated navigation, flight plan management, aircraft performance calculation, and flight guidance. Because the use of flight management system can provide regional navigation capabilities, save fuel, reduce the burden on the pilot, and improve the safety and economy of flight tasks, it has been widely used in civil aircraft. [0003] The integrated management of the radio navigation system is an important navigation function of the civil aircraft FMS. For example, Airbus 320 uses FMS to control 2 VHF omnidirectional direction finders (VOR), 2 range finders (DME) and 2 instrument landing systems (ILS). and other radio navigation equipment for comprehensive management. According to the radio navigatio...
