Ultra-Wideband (UWB) technology, as a new wireless communication technology, has shown great application potential in the field of outdoor positioning and ranging with its characteristics of high precision, high speed and low power consumption. This paper will deeply discuss the technical principle, application advantages and future development trend of outdoor positioning and ranging UWB chip.
Ii. Overview of UWB technology
UWB technology is a kind of wireless communication technology that transmits data by non-sinusoidal narrow pulse from nanosecond to microsecond. It has the characteristics of extremely wide bandwidth, fast transmission speed, strong multi-path resolution, etc., and can achieve centimeter-level or even millimeter-level positioning accuracy. In the outdoor environment, UWB technology can effectively overcome the limitations of traditional positioning technology such as GPS affected by weather, terrain and other factors, and provide a more reliable and accurate solution for outdoor positioning and ranging.
Third, the technical principle of outdoor positioning UWB chip
Outdoor positioning UWB chip is mainly based on the principles of time difference ranging (TDOA) and arrival Angle ranging (AOA) to achieve high precision positioning. By measuring the propagation time of the signal from the transmitting end to the receiving end, combined with the known propagation speed of the signal, the distance between the two can be calculated. At the same time, the specific position of the transmitting end can be further determined by measuring the arrival Angle of the signal from multiple receiving ends. This multi-dimensional measurement method enables UWB positioning technology to achieve high-precision positioning in complex and changeable outdoor environments.
