摘要: We propose a high-accuracy, low-cost UWB-IR wireless location system based on the quasi TDOA method. The consists of anchor nodes, synch node and server. nodes synchronize each other as regulated by so that synchronization is always precise in process. To make simple, uses acquisition tracking functions can measure time when signal received accurately pulse width. In addition, we performed experiment indoors average error measurement was 22-cm
