[Example] National Route Kilopost Standardization

Introducing the application of network-type RTK-GPS in national highway kilometer post marking!

We would like to introduce a case in which Tohoku Engineering Co., Ltd. applied network-type RTK-GPS for "National Route Kilometer Post Standardization." In this case, a reference point was established at the 1-kilometer post of National Route 45 in 2006, and a PAS compatible with network-type RTK-GPS was introduced for the work of assigning coordinates. The company was looking for a machine that could obtain coordinates directly and accurately, as pulling coordinates from traditional public coordinate triangulation points or electronic reference points using TS would result in an enormous amount of work. As a result, by resetting the GPS measurements every time to fix the multipath issues, the influence of multipath could be confirmed, allowing for observations to be conducted with confidence. 【Benefits and Effects】 ■ The accuracy was almost unchanged from the results obtained through static observations, and there were no issues in achieving results. ■ It was possible to reduce work time. *For more details, please refer to the PDF document or feel free to contact us.
