Document Type and Number:
WIPO Patent Application WO/2024/080201
Kind Code:
A1
Abstract:
Provided are: a distance measurement system that is configured so that a measurement frequency can be set in accordance with a measured distance, thereby enabling precise distance measurement; a communication station; and a distance measurement method. The distance measurement system includes a first communication station and a second communication station, and the second communication station has a distance measurement unit that performs distance measurement processing for measuring the distance to the first communication station on the basis of a result of the second communication station having bidirectionally transmitted a signal between the second communication station and the first communication station, and a frequency setting unit that sets the frequency with which the distance measurement unit performs the distance measurement processing, in accordance with the distance measured by the distance measurement unit.
