Aviation navigation signal simulation system applied to flight check

Abstract

The invention discloses an aviation navigation signal simulation system applied to flight check, which mainly comprises a control computer, a multimode receiver, an aviation signal generator, an ARINC (Aeronautical Radio Incorporated) 429 bus, an emission antenna and a receiving antenna. According to the simulation models of various navigation signals under different flight procedures, the system utilizes a simulation system control program to control the aviation signal generator to generate various navigation signals; the navigation signals are sent out via the emission antenna so as to provide an analog simulation signal for the flight check system; and cost for researching, calibrating and maintaining the flight check system is lowered. The aviation navigation signal simulation system can better simulate navigation signals, such as ILS (Instrument Landing System), VOR (Very High Frequency Omnidirectional Radio Range), DME (Distance Measure Equipment), Marker and the like and has the advantages of low cost, beautiful interface and good stability.

Description
