Pentasonics is the start-up that offers a revolutionary technology for Locating, Identifying and Tracking Objects. We have developed a technology to create real-time systems for the "location and tracking’’ at affordable costs. This technology allows to identify and track the 3D location and orientation of a variety of objects. Our system offers the ability to locate many "objects" inside houses, buildings or open places, even in presence of acoustic or electromagnetic disturbances, by adopting an innovative algorithm able to estimate the position of identical remote devices. The location is in the range of dozens of meters and the accuracy in the order of millimeters, taking advantage of the ultrasounds properties, according to the accuracy required.
