Title:
MOVING BODY, POSITIONING SYSTEM, POSITIONING PROGRAM, AND POSITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/111549
Kind Code:
A1
Abstract:
[Problem] To provide a moving body, positioning system, positioning program, and positioning method such that it is possible for the moving body to estimate its own position quickly and highly accurately using a GNSS using carrier phases. [Solution] A moving body according to the present invention comprises a sensor, a map position estimation unit, a relative position estimation unit, a GNSS reception unit, and an absolute position estimation unit. The sensor acquires periphery information. The map position estimation unit estimates the position of the moving body in a local map on the basis of output from the sensor. The GNSS reception unit receives GNSS positioning information using a first carrier phase distance. The absolute position estimation unit estimates the absolute position of the moving body on the basis of the GNSS positioning information using the first carrier phase distance, GNSS positioning information using a second carrier phase distance received in another moving body, and a relative position.
