  • Positioning system, base station, and positioning method
    Patent number: 11921220
    Abstract: To provide a positioning technology capable of measuring a position of a moving object moving at high speed with high reliability, high accuracy, and high speed. The positioning system 1000 can obtain accurate position data using the positioning information collected from a plurality of base stations, and deliver the obtained accurate position data to the base station. In the positioning system 1000, the base station serving as the position reference station can always hold the accurate position data based on the accurate measurement result data. In the positioning system 1000, the base station whose accurate position is known is used as a position reference station to perform RTK positioning with, for example, the mobile station, thus allowing the position of the mobile station to be measured with high accuracy.
