Abstract

This paper describes the real time wireless communications and positioning technology that applied the electronic Rover-based system developed in this paper, and actual onsite measurement results are presented. This paper also calculated the velocity-field that can express the velocity distribution of rivers through a post-processing process using the measured results. The developed system enables five electronic Rovers to be operated in one frequency band, respectively, by dividing the frequency band into three bands, and therefore, the velocity can be measured by using 15 electronic Rovers. The electronic Rover system can measure actual flow paths using the latest GPS technology, through which the system is judged to contribute to the improvement of hydrometric accuracy. The electronic Rover system can calculate accurate flow velocity by applying various real time wireless communications technologies, in addition to GPS-based positioning technology. Because the system can carry out measurement and analysis with little manpower, regardless of site conditions, hydrometric efficiency is expected to be enhanced when floods occur.
