Title:
POSITIONING DEVICE AND POSITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/154131
Kind Code:
A1
Abstract:
In a positioning unit 100 of a locator device, a code positioning unit 104 calculates a host vehicle position and a receiver clock on the basis of GNSS satellite orbits for which the error indicated by positioning reinforcement signals has been corrected and first corrected pseudoranges that are GNSS satellite pseudoranges for which the error indicated by the positioning reinforcement signals has been corrected. For a plurality of GNSS satellites for which multipath influence is smaller than a predetermined value, a receiver-clock-bias-error correction unit 107 determines the difference between the distance between the position of the GNSS satellite and the position of the host vehicle and the first corrected pseudorange as an unknown error and determines a pseudorange receiver clock bias error from the average of the unknown errors. A code positioning correction unit 108 recalculates the position of the vehicle using second corrected pseudoranges obtained by correcting the first corrected pseudoranges using the receiver clock bias error calculated by the receiver-clock-bias-error correction unit 107.
