Abstract
A real-time method and system for locating a mobile object or person in a tracking environment. The method includes modulating a first carrier signal with a first packet including a first set of data to obtain a modulated first signal and transmitting the first signal. The first signal contains the first packet and has a first precision and a first range within the environment. The steps of modulating and transmitting are repeated until a modulated second signal is received within a time period after the step of transmitting. 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 second signal is demodulated to obtain the second packet. Location is determined within the environment based on the second packet.
