Abstract: Computerized systems and methods are provided for locating at least one object within a predefined cell or location. In accordance with one implementation, a location system is provided which comprises at least first and second receivers and first and second transmitters, respectively, including first and second internal clocks, the receivers and the transmitters, respectively, having known locations. The location system further includes a transmitter and a receiver, respectively, worn or carried by the object and designed to communicate by signal exchanges with the receivers and the transmitters, respectively. The location system further includes electronic circuits designed to compute position related information of the object based on the signal exchanges.
