The mystery of the bat's way of communication and navigation has fascinated mankind through all times. Our ears are not capable of picking up the most fascinating and pervasive night sounds, the ultrasonic echolocation calls of bats. Bats have been navigating the night skies for more than 50 million years, but it was not until the late 1700s that people began to understand and appreciate just how sophisticated the orientation system was. Late in the eighteenth century, an Italian scientist, first documented that bats were using a kind of "sixth sense" to navigate in complete darkness.

Sonitor Technologies has now managed to make a practical Indoor Positioning System (IPS) inspired by the ultrasound used by bats.
