摘要

The moving object tracing system has a transponder retransmitting satellite signals after a frequency offset. A processor has a demodulator spread spectrum recovery loop (20) forming an error recovery loop. A unit (40, 41) detects the frequency offset. A section (50) finds the speed information. The speed information section finds the carrier recovery loop error after correction of the bias from the frequency offset, which is the sum of the satellite to mobile and mobile to satellite dopplers.
