摘要：Position determining apparatus including at least one base transmitter/receiver(BTR) station including a base transmitter which periodically transmits timing signals anda plurality of mobile transmitter/receivers (MTR). Each MTR includes a mobile receiveroperative to receive timing signals transmitted by at least one base transmitter;synchronization circuitry receiving the timing signals and providing a spread-spectrumfrequency-hopping sequence characteristic of the particular MTR; and a mobile
transmitter producing a radiated frequency hopped signal responsive to the frequency-hopping sequence and the timing signal.
