The core of the hardware is the autopilot Easy Pilot developed by UAS Europe
AB. It contains two central processing units (cpus) responsible for control, communication
and sensor data processing. A bunch of sensors are used such as an
inertial measurement unit (imu), a barometer and a gps-receiver. The system
can receive flight commands through a radio controller (rc) or through a ground
station control. The autopilot is also capable of sending back flight data to the
ground station. A map of the different hardware components is seen in Figure
