Positioning system that uses signals from a point source
Systems for tracking, containing, and controlling moving objects such as vehicles, boats, airplanes, animals, and people use wireless RF or microwave signals to calculate position within a predefined boundary. The system has antennas in a location, and has processing for determining location either on a device on the mobile device or at a base station. The boundary can be arbitrary and can be learned during a set-up process.
