Abstract

The invention relates to a terminal positioning method and device, a storage medium and a chip, and is applied to an ad hoc network, the ad hoc network comprises user equipment, network equipment and at least three pieces of relay equipment, and the method comprises the following steps: obtaining positioning measurement information, the positioning measurement information comprises corresponding TA1 values obtained by carrying out TA measurement on the at least three relay devices by the network device, and corresponding TA2 values obtained by carrying out TA measurement on the user equipment by the at least three relay devices; and performing position calculation of the user equipment based on each TA1 value and each TA2 value in the positioning measurement information to obtain position coordinates of the user equipment. In this way, the technical problem that in the related technology, positioning precision is low due to the fact that GNSS is adopted can be solved.
