\* Due to partial overlapping of sensors, the use of the lower visual positioning system with the TOPODRONE laser scanner installed is not recommended. It is recommended to land the drone in manual mode when conducting ALS to reduce shock effects on the landing gear and TOPODRONE during landing. The manufacturer is not responsible for the stability of operation of the DJI M300 RTK drone with the lower visual positioning sensors turned on.
