Achieving high-precision positioning with an error of a few centimeters using RTK technology.
The "centimeter-level positioning service" provided by ALES is a service that delivers correction information generated by the "ALES distribution system" based on signals received by SoftBank's unique reference points (fixed stations) to GNSS receivers mounted on agricultural machinery, construction equipment, autonomous vehicles, drones, etc., via the internet (Ntrip method). By utilizing this correction information along with the signals received by the GNSS receiver to perform RTK positioning, it becomes possible to achieve high-precision positioning with an accuracy of a few centimeters in real-time. Additionally, the correction information generated by the "ALES distribution system" can be linked to GNSS receivers via smartphones.

Company information
ALES Corporation is a company established in July 2018 through a joint investment by SoftBank Corp. and Enabler Inc., which has technical expertise in satellite positioning. Based on the signals received by SoftBank's unique reference points, ALES generates correction information using the "ALES Distribution System (*1)" and provides the necessary correction information for high-precision positioning to GNSS (*2) receivers (including dedicated devices, smartphones, etc.), or performs correction calculations on the cloud to directly deliver highly accurate location information to GNSS receivers, enabling centimeter-level positioning services. Please feel free to contact us if you have any inquiries. *1 The ALES Distribution System is our proprietary high-precision positioning information distribution system based on RTK (Real Time Kinematic) positioning. *2 GNSS (Global Navigation Satellite System) refers to the general term for satellite positioning systems such as QZSS (Quasi-Zenith Satellite System), GPS, GLONASS, and Galileo.
