The chirp is a constant amplitude oscillation that increases in frequency from a user defined minimum to maximum frequency, generally referred to as a frequency sweep. The injection points are defined by the :ref:`SID_AXIS` parameter and there are points in the Attitude and Position Controller. For any injection points in the Attitude Controller, the user is required to fly the aircraft through an underlying STABILIZE like flight mode. For any injection points in the Position Controller, the user controls are locked out and will not be able to affect the control of the vehicle. The resulting flight data is logged for math analysis and model generation after the flight.
