Team RAPTORS 11/4/2019 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. 11/4/2019 Team RAPTORS

Project-Specific Success Criteria Team RAPTORS 11/4/2019 Project-Specific Success Criteria An ability to wirelessly transmit and receive packet data. An ability to relay aircraft position and orientation utilizing inertial and navigational sensors. An ability to capture images and relay them serially to the ground station. An ability to control the aircraft servo motors via a microcontroller interface. An ability to amplify an RF signal to 1 watt PEP of transmission power. 11/4/2019 Team RAPTORS
