[Example] National Route Kilometer Post Marking

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

We would like to introduce a case where Tohoku Engineering Co., Ltd. applied network-type RTK-GPS in "National Route Kilometer Post Positioning." 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 a massive workload. As a result, by resetting the multipath concerns with GPS surveying each time to achieve FIX, the influence of multipath could be confirmed, allowing for observations to be conducted with peace of mind. 【Benefits and Effects】 ■ The accuracy was almost the same as the results obtained from 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.
