Introducing the application of FKP-GPS measurement and ultrasonic level meters for continuous elevation measurement of moving objects!
We would like to introduce a case study conducted by Shin Gijutsu Consulting Co., Ltd. on the Chitose River embankment regarding the application of "FKP-GPS surveying and ultrasonic level measurement for continuous elevation measurement of moving bodies." The site is located between 7.0 km and 12.0 km of the first-class river Chitose River, which flows through Ebetsu City and Chitose and Eniwa Cities. To understand the condition of the construction reference surface of the embankment built on soft ground, continuous elevation measurement using a moving body was conducted, along with a comparative verification against direct leveling. The vehicle was equipped with a high-precision GPS receiver and an aerial level meter, obtaining coordinate values and indirect elevation values every second using the FKP method. Additionally, for comparison with direct leveling, direct elevation observations were made at the points where the level meter sensor made contact. Comparative measurements were taken at 77 identical points over a 3 km section on both the right and left banks. [Results (excerpt)] ■ Comparison with direct leveling (KP reference) - Less than 5 cm: 68.8%, less than 10 cm: 97.4% ■ Comparison with existing benchmark results - Maximum ΔX 0.022m, ΔY 0.013m, ΔH 0.022m - Standard deviation ΔX 0.010m, ΔY 0.007m, ΔH 0.010m *For more details, please refer to the PDF document or feel free to contact us.

basic information
[Examination] ■ In conventional longitudinal surveys, results are displayed linearly every 200 meters, whereas FKP continuous measurement uses 1-second data, allowing for the expression of detailed terrain changes. * For more details, please refer to the PDF document or feel free to contact us.
