The drone assembly with TOPODRONE LiDAR looks like this ![Installing TOPODRONE LiDAR on DJI Matrice 300 / M350](https://topodrone.com/knowledge/i/cd2a8bb675e77522.png) | You can start performing ALS ![Installing TOPODRONE LiDAR on DJI Matrice 300 / M350](https://topodrone.com/knowledge/i/31ea1cd5991a75ef.png) |

\* Due to the partial overlap of the sensors, the use of a lower visual positioning system with TOPODRONE LiDAR installed is not recommended. It is recommended to land drones during ALS in manual mode to reduce the impact on the landing gear and TOPODRONE LiDAR during landing. The manufacturer is not responsible for the stability of operation of the DJM 300 RTK drone with the lower visual positioning sensors turned on.
