Document Type and Number:
WIPO Patent Application WO/2021/192422
Kind Code:
A1
Abstract:
[Problem] To provide a configuration with which it is possible to estimate the position of a device more precisely. [Solution] A control device comprising a control unit which: acquires one or more distance measurement values indicating the distance between a variable-position communication device, the position of which is variable relative to a target space delimited by an object, and each of one or more fixed-position communication devices, the positions of which are fixed relative to the target space, said one or more distance measurement values being obtained by wireless communication between the variable-position communication device and the one or more fixed-position communication devices; and estimates the position of the variable-position communication device relative to the target space on the basis of the one or more distance measurement values.
