TWR UWB positioning system kit composition

SKYLAB is the world's leading manufacturer of UWB indoor positioning systems. SKYLAB has developed and produced the TWR UWB positioning system kit. The system kit includes two parts: UWBpositioning base station and UWB label.

The positioning system can use the TWR ranging base station VDU2506 or the core board SKU620. UWB positioning labels are in the form of badges, helmets, bracelets, and other products.

4.Card UWB Tag VDU1501

A card UWB positioning label VDU1501 launched by SKYLAB. It integrates DW1000 and nRF52832 chips and supports TDOA/TWR positioning algorithms.

VDU1501 supports UWB positioning and ranging applications with a positioning accuracy of 10-30 cm. It comes with a lanyard, has an SOS distress button, and is IP67 waterproof.

UWB positioning system installation instructions

1. Installation requirements

In order to achieve the best positioning effect, the following items should be paid attention to when installing the base station:

(1)Accurate calibration requires at least 4 labels to be installed, and the area enclosed by the labels is best for calibration.

(2)All labels should be at least 25 cm away from the wall. Do not block the antenna around the label. If there is a wall surrounding it, move it out as far as possible, and try to stay away from steel products.

(3) The label is placed on a horizontal plane, and there is no obstruction between the label and the base station.

(4)The plane coordinate error of label placement cannot exceed 20 cm.

(5) The positioning accuracy of the device in the three-dimensional interval enclosed by the label will be relatively high.

2. Reference installation model

(1)Install 4 uwb labels on the top four corners of the positioning area.

(2)UWB anchors can be positioned in the three-dimensional space area enclosed by four uwb tags.

(3)The spacing between UWB tags is between 3 meters and 30 meters.
