2. 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

15. 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.
