Abstract
A system configured to perform operations including: determining a first received signal strength, at a first locator device located at a first location, for a signal transmitted by a target device; determining a second received signal strength, at a second locator device located at a second location, for the signal transmitted by the target device; determining a third received signal strength, at a third locator device located at a third location, for the signal transmitted by the target device; determining an average received signal strength of the first, second, and third received signal strengths; and determining a first distance from the first locator device to the target device based at least on (a) the average received signal strength, (b) the first received signal strength, and (c) the distance from the first locator device to a circumcenter of the first location, the second location, and the third location.
