What is RTK?
RTK (Real-Time Kinematic) is a technology that utilizes position information from a reference station to achieve high-precision positioning. While conventional GPS has an error of several meters, RTK can reduce this error to within a few centimeters. With RTK, centimeter-level high-precision positioning becomes possible, and its application is expected in many industrial fields, starting with agriculture.

basic information
At ALES Corporation, we utilize the unique reference points received by SoftBank Corporation's signals to generate and distribute correction information through the ALES distribution system. By using the generated/distributed correction information along with the signals received by GNSS receivers (mobile stations), high-precision positioning with an accuracy of a few centimeters can be achieved in real-time through RTK positioning. By applying corrections with the correction information, it becomes possible to provide high-precision location information for agricultural machinery, drones, construction equipment, autonomous vehicles, and more.

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.
