Raspopov V. Ya., Tovkach S. E. Navigation system of a pilotless mini aircraft

The navigation system structure for a pilotless mini aircraft by weight of up to 4 kg is discussed. The system is designed as a stand-alone module intended for unmanned autonomy, takeoff and landing under the supervision of a ground operator. The modules and components providing aircraft orientation and navigation in all flight regimes are identified. System resolution in navigational parameters measurement is analyzed.
