Multi-Base-Station UWB Time Difference Positioning System

This paper proposes a multi-base station array layout scheme. Select the base station array through the label, and then use the base station array to accurately locate the label. Compared with other positioning methods, the accuracy of the scheme is greatly improved. In this scheme, STM32 is used to control DW1000 to realize ultra-wideband (UWB) signal receiving and transmitting on the hardware. Combined with time different of arrival (TDOA) positioning algorithm principle, the accuracy is improved by experiments, and the positioning accuracy can be controlled within 5cm.
