Project Overview
Remotely operated drone aircraft with a real-time flight data acquisition system.
Custom radio transceiver and sensing equipment will relay inertial and navigation data.
Data transmitted to ground station and displayed onscreen in real-time.
The ground station will also send control commands from a pilot to the aircraft.
