Bluetooth Positioning on Ships

There’s new research from College of Information Engineering, Shanghai Maritime University, China on BSSH: Bluetooth Indoor Positioning Strategy for Ship Cabin Based on Hierarchical Area.

The locating and monitoring of ship crew is an important part of ship safety when it comes to adherence to duty regulations. The paper shows how Bluetooth works within the complex electromagnetic and spatial structure of a ship.

The research proposes a BSSH positioning system using fingerprinting that divides the ship up into hierarchical areas.

The BSSH system eliminates the affect of distant beacons on the location results thus reducing the computational effort and improving accuracy.

The system demonstrated better results than a traditional KNN positioning algorithm. It had higher positioning accuracy, better stability and an accuracy rate of more than 80%.
