On the basis of MG- 1, DJI upgraded the flight control system, environmental awareness system and spraying system of MG-1S.

As for the flight control system, the MG- 1S adopts DJI A3 flight control, and the algorithm is fully optimized, which helps the UAV to fly smoothly in the case of liquid medicine sloshing. Coupled with double barometers and double compasses, the flight control system can switch to another set of sensors immediately when the flight data is abnormal to ensure flight safety.

As for the environmental awareness system, MG- 1S is equipped with high-precision millimeter-wave radar on the front, back and bottom. Forward squint radar and backward squint radar can detect the terrain in advance, and combine with downward looking radar to accurately determine the height. MG- 1S can perceive the terrain change in the flight direction in advance through uninterrupted scanning, and adjust the flight height in time according to the terrain and crop height to realize ground-like flight and uniform spraying.

As for the spraying system, MG- 1S is equipped with two customized pumps, which can control the front and rear two pairs of nozzles respectively, and allow users to choose single spraying before, single spraying after and full spraying according to different operation requirements ... It is better to train them.

As for the spraying system, MG- 1S is equipped with two customized pumps, which can control the front and rear two pairs of nozzles respectively, and allow users to choose three different spraying modes according to different operation requirements: front single spraying, rear single spraying and full spraying. The newly added pressure sensor and flow sensor can monitor the spray flow in real time and dynamically control the flow and speed of drugs during the operation; The newly designed two-stage spraying system solves the occasional phenomenon of uneven spraying and substandard settlement when the traditional sprinkler works at both ends of the route. The new sinking nozzle adopts downward pressure wind field, and the nozzle assembly realizes instantaneous start and stop, which makes the spray more accurate and improves the settling effect of the liquid medicine. The water pump and medicine box are also optimized, which is convenient for dosing and easy to disassemble and clean; Compared with the previous generation products, the screen area has increased by 20 times, and the double screen design reduces the nozzle blockage caused by water distribution, powder or liquid medicine.

Mechanically, MG- 1S strengthened the main arm, optimized the design of the tripod, and was easy to assemble and disassemble. Waterproof glue film is added to the electronic governor, which can isolate rain and dust, resist the corrosion of pesticides, salt spray and other liquids, and provide protection for the electronic governor.
