摘要: The invention relates to the field of wireless communication, and discloses a distributed asynchronous positioning system method based on an ultra-wide band. According invention, comprises at least one beacon tag. beacons are independent mutually, arrangement positions fixed. Moreover, coordinates known for all tags. When tags need be obtained, transmit range-finding requests, employ three-direction algorithm obtain distances from after responses obtained in signal coverage. distance beacon, calculate embodiment achieves modes user side, network side third same time, devices do not coordinate with each other advance completely mutually. equipment is limited.
