ABSTRACT:
A method of communicating with a remote precision transponder includes the step of transmitting first signals to the transponder. The first signals are received in the transponder, and second signals representative of the first signal are delayed therein for a precise time interval. After the precise time interval, third signals representative of the delayed second signals are transmitted from the transponder. Detailed embodiments of a transponder for performing these steps are also disclosed.
