Rangefinders (landing page)

Copter/Plane/Rover support a number of different rangefinders including Maxbotix Sonar and Pulsed Light LED range finders.


If you get a “Bad LiDAR Health” message in Mission Planner this is caused because the rangefinder isn’t enabled for landing. This is done through the RNGFND_LANDING parameter and if set you should see the message disappear.


RNGFND_MAX_CM must be set to a tested, appropriate value. If RNGFND_MAX_CM is set to a value greater than the range of the sensor, the flight controller will not respond correctly to the data provided.

Follow the links below (or in sidebar) for configuration information based upon your set-up.
