Project Introduction Initial Scope: UAV Ground Station Current Scope Collect and display in-flight telemetry data Allow user to control aircraft through a computer (joystick/keyboard input) Display pseudo real-time imagery on computer to aid in navigation A building block for a future ground station capable of fully automated flight Current Scope Use of ArduPilot meets many of the future goals Project expanded to include seeded fault detection Detect faults using simple sensors Faults should represent real-world risks to combat/surveillance aircraft

Ardupilot Capabilities Includes 3-axis gyro, accelerometer, magnetometer, barometer. Optional off-board 5Hz GPS (included in price) 4Mb datalogging memory Up to 8 I/O channels Open source, coded in C. Allows manual flight or mission scripting. Waypoints can be defined for automatic flight or the plane can loiter around a "home" point.
