To meet the growing demand for indoor wireless positioning in B5G environment, a high-precision indoor positioning system is designed in this paper. The designed system adopts the fusion of multi-source positioning techniques, to chieve the reasonable cost and reliability. First, Considering the B5G environment, a two-steps fusion algorithm is proposed for the designed system, in which the UWB and ZigBee techniques, the trilateration and the maximum likelihood algorithms are fused in turn through the error comparison to obtain the high-precision estimated locations. Then, the proposed positioning system is verified in a plane space of 10 m$\times$10 m by simulations, and the reference nodes of UWB and ZigBee are designed respectively. The received signal strength (RSS) ranging is used, based on which the distance measurements of both UWB and ZigBee are established. The simulation results show that the designed system using the multi-source fusion algorithm has better performance than other algorithms the terms of location accuracy, and can satisfy the requirements of high-precision indoor positioning.
