SKYLAB has developed and launched the Mi Bluetooth indoor positioning kit and the TDoA UWB indoor positioning kit. In response to the TWR ranging needs of some industry customers, SKYLAB has launched TWR active positioning system and TWR passive positioning system. In this article, I will introduce the TWR passive positioning system in detail.

Introduction of UWB TWR Passive Positioning System

The principle of the TWR passive positioning system is similar to that of TDoA. Real-time ranging between UWB tags and UWB base stations. It uploads the distance information to the background resetter through the UWB base station. Then the server parses the location information of the UWB tag.

SKYLAB UWB TWR positioning system includes UWB positioning base station, UWB positioning tag and POE switch, server, and terminal display device. Customers can build a high-precision display environment for fast and on-site high-precision UWB positioning demonstrations.

Working principle of UWB TWR indoor positioning

TWR is a two-way ranging algorithm. Algorithms transmit wireless signals to base stations based on tags. The base station sends the wireless signal to the tag after receiving the wireless signal from the tag. After the tag receives the data, it sends it to the base station again. The base station calculates the distance by the time of three flights of radio waves between the base station and the tag.

TWR passive positioning system product installation requirements

In order to achieve the best positioning effect, customers should pay attention to the following items when installing the base station.

●Accurate calibration requires the installation of at least 4 UWB base stations. Calibration works best in areas surrounded by base stations.

●All base stations are at least 15 cm away from ceilings and walls. There should be no shelter around the antenna of the base station.

●The installation height of the base station needs to be more than 2.5m above the ground. The distance between base stations depends on the transmit power of tags and base stations. The maximum gain of single-stage PA can reach 200 meters, and the maximum gain of two-stage PA can reach 500 meters.

●The installation location of the base station should be more than 15cm away from the ceiling and walls

Reference installation model

According to the installation requirements, you can install 4 UWB base stations at the top four corners of the positioning area. UWB tags can be positioned within a three-dimensional space area surrounded by four UWB base stations. The distance between UWB base stations can be controlled within 200 meters.
