Angle of Departure (AoD) measurement technology using BLE - Indoor positioning [High-precision positioning]
Achieving a high-precision positioning system! Aggregating the smartphone's location direction towards the beacon.
This is a development case that achieved angle measurement (radio wave arrival direction estimation) on a typical smartphone by processing the signal from a BLE beacon transmitted from a special antenna. By installing multiple units of this special BLE beacon and aggregating the smartphone's direction relative to each beacon, a high-precision positioning system called "BLEGONIO" was realized. This system won third place in the Microsoft Indoor Localization Competition 2017, an international competition that challenges indoor positioning accuracy. *For more details, please refer to the PDF document or feel free to contact us.*
