BLE AOA POSITIONING HARDWARE SOLUTION

Provide a AOA gateway+ beacon positioning hardware solution

AoA Bluetooth Positioning Solution Introduction

Dusun uses the Angle of Arrival (AOA) positioning algorithm to reach the unique direction of the incoming wave and position of the tag, which improves the 5-meter accuracy of traditional low-precision Bluetooth by ten times and reaches 0.1-0.5 meter average accuracy. The system supports Bluetooth 5.1 and is backward compatible with all Bluetooth 4.0 tags or phones.

BLE AOA Positioning 02

Single Area Two-Dimensional Locating in Single Anchor Area

A single gateway calculates and obtains the actual heading angle/pitch angle of the tag, and obtains a unique ray. According to the determined tag height, a single gateway can calculate and obtain a unique spatial absolute coordinate.

2 layer 1

Large Area, Spatial Locating

The strap-down combination of multiple gateways obtains a larger positioning coverage space, and multiple anchor course angel calculations improve the global spatial accuracy level.
