Last month we successfully completed the testing of our personal #trackingsystem on the Zr. Ms.Johan de Witt together with Damen shipyard and RH-Marine. Our tracking system is based on Bluetooth Low Energy technology that allows its user to track whether someone is in room A or room B, even with the system walls as partition walls. With the new antennas from #Nokia, it will soon be possible to determine positions as accurately as 50 cm.
