1. A CORRELATION DOPPLER SYSTEM FOR DETERMINING THE TIME OF INTERCEPT BETWEEN A DOPPLER FREQUENCY OF A RADIO FREQUENCY SIGNAL OF A MOVING SATELLITE AND A FIXED REFERENCE SIGNAL AT A RECEIVING POSITION COMPRISING:
- MEANS FOR RECEIVING THE TRANSMITTED RADIO FREQUENCY SIGNAL FROM A MOVING ASTELLITE;
MEANS FOR MIXING SAID RECEIVED SATELLITE SIGNAL WITH A FIXED REFERENCE SIGNAL TO PRODUCE A BEAT FREQUENCY SIGNAL BETWEEN SAID SIGNALS BECAUSE OF THE VARIATION OF THE FREQUENCY OF SAID SATELLITE SIGNAL DUE TO THE DOPPLER EFFECT CAUSED BY THE MOTION OF THE SATELLITE;
DELAY MEANS FOR COMBINING VARIOUS DELAYED SIGNALS OF SAID BEAT FREQUENCY SIGNAL FROM THE FIRST HALF OF SAID DELAY MEANS WITH SECOND HALF OF SAID DELAY MEANS;
MEANS FOR FEEDING SAID BEAT FREQUENCY SIGNAL FROM SAID MIXING MEANS TO SAID DELAY MEANS;
AND SUMMING MEANS FOR ADDING THE COMBINED DELAY SIGNALS OF SAID DELAY MEANS WHEREBY A PEAK OF SAID COMBINED SIGNALS WILL INDICATE THE TIME OF INTERCEPT BETWEEN THE DOPPLER FREQUENCY SIGNAL AND THE FIXED REFERENCE SIGNAL AT A RECEIVING POSITION.
