+=================
+Precision Landing
+=================
+
+Copter, QuadPlane and Rover support precision landing using the `LANDING_TARGET <https://mavlink.io/en/messages/common.html#LANDING_TARGET>`__ mavlink message
+
+References:
+
+- :ref:`Copter's user wiki for precision landing <copter:precision-landing-with-irlock>`
+- `QuadPlane discussion of precision landing <https://discuss.ardupilot.org/t/quadplane-precision-landing-support-testers-needed/114072>`__
+- `MAVLink's Landing Target documentation <https://mavlink.io/en/services/landing_target.html>`__
+- :ref:`Testing Precision Landing in SITL <adding_simulated_devices>`
+
+Users should follow the :ref:`user precision landing wiki page <copter:precision-landing-with-irlock>` including setting :ref:`PLND_TYPE <PLND_TYPE>` = 1 (MAVLink)
+
+The external camera system should send the `LANDING_TARGET <https://mavlink.io/en/messages/common.html#LANDING_TARGET>`__ message to the autopilot at no less than 1hz (a higher rate is better).
+
+If the x (e.g. forward), y (e.g. right) and z (e.g. down) distance to the target is known (in body frame) then "x", "y" and "z" fields should be populated, and "position_valid" should be set to "1".
+
+If only the body-frame angle to the target is known then "angle_x" and "angle_y" fields should be populated and "position_valid" should be set to "0".
