Design of UWB Indoor Positioning System Based on Stm32f103c8t6 MCU

Ultra wideband (UWB) indoor positioning technology has become an important research direction in the field of wireless positioning technology because of its high resolution, high wireless transmission rate and strong anti-interference performance. It will play an important role in the construction of smart cities such as intelligent transportation and intelligent manufacturing in the future. The c-taylor and adaptive robust Kalman filter localization algorithm based on TOA make up for the shortcomings of Chan algorithm and Taylor algorithm, reduce the NLOS error, and have better positioning performance. Based on TOA's c-taylor and adaptive robust Kalman filter positioning algorithm, this design selects the 32-bit controller Stm32f103c8t6 with arm coretex-m as the main control chip, and uses the embedded system of MODBUS-RTU communication protocol to realize the design of UWB indoor positioning system. The proposed algorithm and the designed positioning system have practical application value.
