3D simulation of A-SMGCS surface movement based on FlightGear: 3D simulation of A-SMGCS surface movement based on FlightGear

A new method to design a 3D surface movement simulation system for A-SMGCS based on Linux operation system and FilightGear flight simulator was proposed.The simulation system was driven by real-time track data of ADS-B.An airport model was built up according to a real airport prototype by modeling of aircrafts,airport layout,terminal,tower and terrain.Because ADS-B track data had no flight attitude data,an algorithm to extract flight attitude from a space vector,which was connected by two pre and post track points,was proposed.Six degrees of freedom(6-DOF) aircraft movement simulation was realized by importing position and attitude data into FlightGear through its multiplayer interface to drive aircraft models.The simulation results show that,the system can simulate surface movement accurately and realistically.The simulation system is low-cost because it is based on free,open source software.
