CERES 16 is capable of flying 24 minutes on a normal flight & 12 minutes on a pest control mode using a 16000mAh dual battery. It can even cover a larger area when HELSEL's 16L Hybrid Container is installed on it. Operation of CERES 16 with the 16L Hybrid Container shows 60 times more efficient than a human being.

Data Link Controller

SESOS-K, The Flight Controller.

cpu image.png

CERES X is equipped with SESOS-K flight controller. With three IMUs, two CPUs, and two barometric pressure sensors equipped, SESOS-K monitors data in real-time during a flight through an advanced diagnostic algorithm. In case of an error regarding one CPU, IMU, or barometric pressure, the second CPU, IMU, or barometric pressure automatically operate in order to maintain the drone's stable flight. 

Generally, the difference in the flight performances of an agricultural drone when the tank is full and when is empty was evidently distinct. This led to the user's struggle in getting used to the drone control. However, CERES's flight controller, SESOS-K, shows equal flight performance regardless of the payload. Another feature of SESOS-K is that it doesn't require the user to manually maintain the drone's altitude since it automatically maintains a stable altitude. 

Smart Point Flight System

Ceres automatically flies during A-B automatic flight according to the user's desired path

and ensures more definitive control.

Intelligent Spraying System

Intelligent Spraying System only sprays during forward & backward flight which consequently reduces waste and pollution of pesticides, thus enabling economical operation.

 In case of lack of pesticide during spraying, CERES X comes back to the initial take-off point through manual flight or automatic back-home function. When it takes off again after replenishing, it automatically returns to the point where it stopped dispersion and then begins spraying again.

Break Point Memory

Hybrid Container

Equipped with Hybrid Container, the pesticide hole got 2 times bigger than the existing tank, allowing efficient pesticide injection.

Easy-to-clean Canopy

With equal spraying power and definitive pest-control, the cleanliness of the upper part of CERES 10S V2 is always maintained, which allows easier management.
