Based on the latest Bluetooth 5.1 technology, BlueIOT uses the Angle of Arrival (AOA) positioning algorithm to reach the unique direction of the incoming wave and position of the tag, which can reach 0.1-meter accuracy and improves the accuracy of traditional low-precision Bluetooth by ten times. With patented technology, the locating anchor is backward compatible with all Bluetooth 4.0 or above tags and supports the high-precision locating service for both IOT tags and LBS phones.
A single anchor calculates the actual heading angle/pitch angle of the tag, and obtains a unique ray. Then according to the height of the tag, a single anchor can calculate and obtain the unique spatial absolute coordinate.
The strapdown combination of multiple anchors obtains a larger positioning coverage space, and multiple anchor course angel calculations improve the global spatial accuracy level.
