A real-time method and system of determining and validating location of a relocated mobile object or person in a tracking environment in which a plurality of sensors are located are provided. The method includes modulating a first carrier signal with a first packet including a first set of data to obtain a modulated first signal. The first signal contains the first packet and has a first precision and a first range within the environment. A modulated second signal is received from at least one of the sensors including the nearest sensor. The second signal contains a second packet including a second set of data and has a second precision and a second range within the environment. The method further includes determining and validating current location of the relocated tag within the environment based on a plurality of second packets.
