The UWB positioning system is a positioning system based on ultra-wideband technology. It is different from traditional communication technology in that it does not require the use of carrier waves, but achieves wireless transmission by sending and receiving extremely narrow pulses with a nanosecond or sub-microsecond level. The advantages of this system include low power consumption, insensitivity to channel fading, strong environmental resistance, no impact on other devices in the same environment, and high positioning accuracy and precision. The UWB positioning system consists of hardware (base station and beacon) and software (embedded software and host computer solution and GUI software). The key part of the base station is ATSAM4E8+DW1000, and the key part of the beacon is STM32+DW1000. This kind of system needs to fix the location of the base station in advance, connect it to the switch through a network cable, and finally connect it to the PC of the host computer. The beacon continuously emits UWB signals. After receiving the signals, the surrounding base stations obtain the location of the beacon through positioning algorithms. In short, the UWB positioning system has the characteristics of high accuracy and low power consumption, and can be used in prison inmate positioning and other scenarios.
The system uses advanced UWB high-precision positioning technology

Uwb precise positioning system is an emerging Internet of Things technology based on ultra-wideband technology that can achieve high-precision positioning and tracking of personnel.
2. Definition and principle of Uwb personnel precise positioning system
Uwb personnel precise positioning system is a positioning system based on ultra-wideband technology. It mainly transmits and receives ultra-short pulse signals and can achieve micron-level accuracy in ranging. The main difference between ultra-wideband signals and other wireless signals is their short-term signal pulse width and bandwidth characteristics. Wider applications using ultra-wideband technology include radar, communications, ranging, data transmission and other fields.
The principle of the Uwb personnel precise positioning system is to place the receiver and transmitter in different locations and send ultra-wideband radio waves to the beacon. Based on the signal received by the receiver and the position and time of the beacon, the distance between the receiver and the beacon can be calculated, and the real-time position of the receiver can be deduced. By calculating the positioning accuracy, the location of the person can be accurately located.
