Introducing the ACSL SOTEN — A compact, NDAA-compliant Japanese drone, offering advanced security and versatile imaging with a one-touch swappable camera system. Lightweight, foldable, and featuring an IP43 rating, it's ideal for demanding missions. With a 25-minute flight time and intuitive operation, the SOTEN is perfect for secure, efficient aerial tasks in challenging environments.
Protected by made-in-Japan secure drone technology
Security measures based on ISO15408* are applied to prevent data leakage and extraction and to provide resistance to hijacking.
Major parts of the aircraft are either domestically produced or procured from highly reliable overseas sources. Security is enhanced with encrypted communications. Acquired data can optionally be encrypted and managed in the Japanese cloud.
*International Standard for Computer Security
One-Touch-Swappable Camera
ACSL SOTEN employs a swappable camera system, a first for a small aerial photography drone, enabling a wide array of camera options.
The standard camera can be swapped with an EO/IR combination camera, a multispectral camera, and an optical zoom camera.
Extensive Scalability, including Closed Network LTE Communication and Offline Maps
With the use of LTE communications, SOTEN can be controlled over the internet, enabling autonomous beyond-visual-line-of-sight (level-3) operations in remote areas such as mountainous terrain and inside industrial plants.
The use of offline maps allows the ground control software application to display maps and manage autonomous flight, even in environments where internet access is not available.
An adapter for mounting the camera on the top of the drone, enabling the inspection of infrastructure from below, is currently under development.
A drone with flight performance that is more than sufficient for real-world operations
With a maximum airspeed of 15 m/s, SOTEN is capable of safe flight in severe conditions, such as natural disasters.
SOTEN is also equipped with SLAS/SBAS (sub-meter positioning augmentation from the Michibiki quasi-zenith satellite system), which can provide more accurate positioning information in Japan, enabling safer takeoff and landing in situations where accurate positioning information is required, such as disaster response.
