The process for drone automatically returning to the RTH point is called RTH.
2.5.5.2.
Protection Logic
When GNSS signal is good, the compass work normally, and the RTH point has been
successfully recorded, if the remote controller signal is lost by any reason during the
operation process, the drone will execute protection action. The protection actions include
landing , hovering and returning.
Notes
：
1. When the remote control has good connection, RTH can be canceled by toggling the
remote controller switch to "S" , and the drone can be controlled manually.
2.
When the remote control has good connection, RTH can be canceled by long
pressing the “ ” button for 2 seconds.

Front and Back Obstacle Avoidance (Optional)
The drone is equipped with a new 77 GHz millimeter wave radar for obstacle detection,
which is unaffected by ambient light and dust. When the working conditions are met, the
radar can detect the obstacles in front of and behind the aircraft. The maximum detection
distance can be up to 20 meters. When obstacles are detected, the drone self-brake to
ensure safety during the operation. The obstacle avoidance function is enabled by default
and can be turned off in the Agriculture Assistant APP.
2.5.6.1. Detection Range
The detection range of the radar module is shown in the following pictures. The vertical
direction is 0° to 15° (see Figure 2-4-1) and the horizontal direction is ±45° (See Figure
2-4-2). If any obstacle is outside the detection range, the radar module cannot sense it so
the pilot should operate carefully. If an obstacle suddenly appears in the detection area,
the radar module needs 0.6s to detect and track the movement of the target.
