The invention discloses a
system for simulating flight tracks of unmanned aerial vehicles on the basis of GPS (
global positioning system)
simulation, and belongs to the technical field of unmanned aerial vehicles. The
system comprises an unmanned aerial vehicle track generating module, a
GPS data processing module, a communication module and a flight control computer. The
system has the advantages that the system is in basic working
modes of analyzing movement of GPS
satellite constellations, optimally positioning four
satellite options and simulating GPS receivers, accordingly, obtained location information of the unmanned aerial vehicles can be converted into corresponding
GPS signals, the
GPS signals can be inputted into the flight control computer, and
GPS navigation simulation experiments for real-time dynamic functions for receiving signals by the receivers at given locations in given time can be implemented; a method is speedy and simple and is high in precision and real-time performance, development processes of
simulation systems can be accelerated, and the efficiency of simulation and
verification work of flight control systems can be improved; NMEA 0183 protocols are generated in
software forms, accordingly, the system can be communicated with true flight control, and transition from virtuality to reality can be implemented.
