1.Self-service flight

Prior to the spraying operation, through the real-time map displayed on the ground control station, four boundary points around the farmland will be selected, then intelligent automatic flight control system will automatically generate a series of work routes and import the agriculture spray drone.

After setting the working command, agriculture spray drone can automatically take off and automatically complete the spraying operation, and then automatically land off to takeoff point.

2.Auxiliary flight

When the agriculture spray drone is set to work in automatic mode, the operator can switch to manual mode during flight and directly remotely control it with the help of the intelligent automatic flight control system. The operation is simple and the efficiency is high.

3.Return mode (one click return)

Welkin A2 and A3 agricultural spray drone have automatic return function. Automatic return includes low-power automatic return, loss of control return and intelligent home return function.

To use automatic return function, it needs successfully record the return point before take-off.

The drone will return automatically after losing the communication signal between the remote control and the drone, and automatically land off to avoid accidental injury.
