Ultra-wideband (UWB) is a wireless carrier communication technology that makes a signal have a bandwidth of the order of GHz by directly modulating an impulse having a steep rise and fall time, and is essentially a wireless technology that transmits and receives a narrow pulse of ultra-short (ns-ps) non-sinusoidal electromagnetic energy, and transmits data accordingly.

UWB occupies a wide spectrum, with a bandwidth frequency of 7.5GHz from 3.1GHz to 10.6GHz being the frequency range used by UWB, and a single channel bandwidth exceeding 500MHz, as specified by the FCC.

Because the time width of the UWB pulse is extremely short, the distance measurement can also be carried out by adopting high-precision timing, and in the indoor positioning application, the UWB positioning technology has the characteristics of good confidentiality, strong multipath resistance, strong penetrating power, high positioning precision, strong electromagnetic compatibility, higher energy efficiency and the like, and has obvious advantages compared with other indoor positioning technologies. The UWB positioning technology adopts positioning data processing equipment, a UWB positioning base station and a UWB positioning tag which store various positioning algorithms to realize the accurate calibration of the position of the UWB positioning tag.

The existing UWB positioning base station receives and transmits positioning messages according to a positioning algorithm, records the receiving and transmitting time of the positioning messages or the arrival angle of signals, and the like, and is also responsible for processing information such as a positioning tag identifier carried by a positioning message terminal, and periodically transmits the collected information to a positioning data processing device for processing. A UWB positioning base station supporting TDOA positioning algorithm comprises a TDOA positioning algorithm management unit, a time synchronization client unit keeping clock synchronization with positioning data processing equipment, a UWB baseband processing unit, a UWB transceiver, a high-precision clock, a power supply management unit, a transmitting and receiving antenna unit and one or more interface units.

UWB indoor location is extensively applied to application fields such as intelligence house, intelligent car, seek thing location, mobile payment, indoor navigation, AR/VR and intelligent earphone.

positioning base stations

001, 002, 003, 004 are fixed at four corners of an indoor ceiling in an indoor room, so as to achieve a better coverage effect of signals. In practical applications, the UWB positioning base station is fixed to a suitable position, for example, as shown in fig. 1, and then the actual coordinate values of the UWB positioning base station are manually measured.

Firstly, suitable positions of the four UWB positioning base stations are not easy to find, even if the suitable positions are found, manual measurement work is large, and accuracy is not easy to guarantee, so that final positioning accuracy of the UWB positioning tags is affected.
