Title: POSITIONING DEVICE, POSITIONING SYSTEM, AND POSITIONING METHOD
Abstract:
[Problem] Reduced positioning accuracy and inability to carry out positioning smoothly. [Solution] A positioning device provided with a reception unit for receiving radio waves from satellites, a detection unit for detecting the satellites on the basis of the radio waves from the satellites received by the reception unit, and a positioning unit for estimating an integer bias using observed values based on the radio waves received from a reference station and the satellites and carrying out positioning, wherein the positioning unit carries out, in parallel, positioning based on a first integer bias determined on the basis of observed values for a first satellite combination and estimation of a second integer bias on the basis of observed values for a second satellite combination and is capable of switching from positioning using the first integer bias to positioning using the second integer bias.
