There is disclosed systems, methods, and computer-readable media for local positioning. A system includes a plurality of anchors placed within a facility, three or more calibration tags, temporarily placed at respective predetermined positions within the facility, and a server. The server instructs the plurality of anchors and the plurality of calibration tags to use two-way-ranging communications to measure respective distances between each anchor of the plurality of anchors and at least three of the three or more calibration tags. The server uses the predetermined positions of the plurality of calibration tags and the measured distances to determine a respective location of each of the plurality of anchors.
