High-precision positioning device and high-precision positioning system

摘要

PROBLEM TO BE SOLVED: To attain a highly-accurate positioning device that can more appropriately determine accuracy of a positioning result in comparison with a conventional device.SOLUTION: A first reception unit 100 is configured to generate observation data, using GNSS signals of an L1 band and L2 band, and a second reception unit 150 is configured to implement first periodicity positioning, using the GNSS signal of the L1 band, and generate CLAS reinforcement data, using a GNSS signal of an L6 band. A CLAS reinforcement second periodicity highly accurate positioning computation unit 201 is configured to implement CLAS reinforcement second periodicity highly accurate positioning, using the observation data generated by the first reception unit 100, and the CLAS reinforcement data generated by the second reception unit 150. A determination unit 202 is configured to determine accuracy of the CLAS reinforcement second periodicity highly accurate positioning, using a positioning result of the CLAS reinforcement second periodicity highly accurate positioning and a positioning result of the first periodicity positioning.SELECTED DRAWING: Figure 1
