Abstract

Abstract:

A hardware platform based on UWB positioning system was designed for further studying the wireless positioning technology based on UWB. The hardware platform is based on the modular design idea, using STM32 as the main controller and communicating with DW1000 RF chip through SPI bus. The UWB RF circuit was designed layout around of DW1000, with the use of full external antenna. The hardware platform designed GPRS wireless communication mode and adopted the TOA positioning mode, and reserved the GPIO peripheral extension interface. The measured results showed that the farthest communication distance was 110 m in LOS environment, the RMSE error of 100 m in the same environment was 20.2 cm, and the positioning error in indoor NLOS environment was 20 cm, which satisfied the research needs of indoor high-precision positioning technology.

Key words: UWB, wirelesspositioning, indoorpositioning, DW1000, TOA, NLOS
