【 摘 要 】

An indoor position system based on UWB modules is introduced in this paper. The time difference is obtained by the communication between the target node and the source node, and the time difference is sent to the upper computer to calculate the position of the target node with the improved TDOA algorithm and kalman filtering algorithm. The test shows that the system has the advantage of high precision and high stability.
