High-precision positioning service "ichimill" that solves challenges in the construction industry - A VRS plan that can also accommodate public surveying is now available.

Ichimill is a SoftBank service that utilizes GNSS signals and RTK positioning technology to achieve high-precision location positioning with an accuracy of a few centimeters. By leveraging over 3,300 SoftBank base stations nationwide as unique reference points, there is no need for customers to set up or maintain reference points. It supports operations that require accurate location information, such as automatic control of construction machinery and drones, progress management at construction sites, infrastructure inspections, and public surveying. Even during wide-area movement, it automatically switches to the optimal reference point, ensuring stable positioning. It contributes to the promotion of construction DX, work efficiency improvement, and enhanced safety.
