UWB positioning base station

The positioning base station (positioning sensor) can determine the position of the tag through the time difference of arrival (TDUA) measurement technology, and transmit the data to the network controller and positioning engine software with centimeter-level positioning accuracy.

UWB Positioning Label

The positioning tag is an active tag, which can be fixed on objects, vehicles or worn on personnel in different forms, and has versatility in different application environments. Its positioning accuracy can reach up to 5-10cm, and the UWB pulse signal emitted by the tag is received and transmitted through the positioning base station (positioning sensor). Each tag has a unique ID number, through which the positioned object can be linked, so that the positioning base station (positioning sensor) can find the actual location through the tag.

The tag transmission signal has a short duration and is capable of allowing hundreds or thousands of tags to be positioned at the same time.

Global location display, historical track, electronic fence, and provide location information to connect with the customer application server, and the specific agreement is negotiated between the two parties;

UWB Ultra-Wideband Positioning Process

1) Each positioning tag sends data frames repeatedly and uninterruptedly with UWB pulses;

2) The UWB pulse train sent by the positioning tag is received by the positioning base station;

3) each positioning base station uses a high-sensitivity short pulse detector to measure the time when the data frame of each positioning tag arrives at the receiver antenna;

4) The positioning engine refers to the calibration data sent by the tag to determine the time difference between the tag reaching different positioning base stations, and uses the three-point positioning technology and optimization algorithm to calculate the tag position.

5) Multi-base station positioning mostly adopts TDOA (Time Difference of Arrival) algorithm.
