Abstract
Abstract The signal radiated from a transmit/receive station contains a transmission message with a clock synchronisation header, a preamble and useful data. This allows synchronous data transmission to a reception from the transponder, in which the regenerated reception bit clock is synchronised or identical with the emitted transmission bit clock. The transponder sends a reply message of similar compsn. from which the clock signals are recovered and a measure of distance is derived from the time delay between the preambles. An average correction to the overall propagation time is obtd. <IMAGE>
