Data collection system employing celestial radiation as a reference

Claim 1

APPARATUS FOR GENERATING A REPRESENTATION OF A TIME INTERVAL IN THE FORM OF A SIGNAL SYNCHRONIZING TWO GROUND LOCATIONS SEPARATED GEOGRAPHICALLY AN EXTENT PREVENTING LINE-OF-SIGHT TRANSMISSION BETWEEN THE LOCATIONS, SAID APPARATUS COMPRISING; FIRST AND SECOND SIGNAL RECEIVING MEANS DISPOSED AT ONE OF THE LOCATIONS, THE FORMER TO RECEIVE TARGET RADIATION SIGNALS FROM AERIAL TARGETS IN THE REGION BETWEEN THE LOCATIONS AND THE LATTER TO RECEIVE RADIATION FROM A PREDETERMINED CELESTIAL BODY VISIBLE FROM BOTH LOCATIONS, THRID AND FOURTH SIGNAL RECEIVING MEANS DISPOSED AT THE OTHER LOCATION, THE FORMER TO RECEIVE RADIATION SIGNALS FROM SAID TARGET AND THE LATTER TO RECEIVE CELESTIAL RADIATION FROM SAID CELESTIAL BODY, SAID FIRST AND THRID RECEIVING MEANS BEING SUFFICIENTLY DIRECTIVE SO AS TO HAVE EFFECTIVELY NO INTERACTION WITH CELESTIAL RADIATION, SAID SECOND AND FOURTH RECEIVING MEANS HAVING A BAND PASS REJECTING INCOMING ENERGY AT TARGET SIGNAL FREQUENCIES, SAID FIRST AND SECOND RECEIVING MEANS WHEN THE TARGET IS NEARER SAID ONE LOCATION BEING ARRANGED AND CONSTRUCTED TO PROVIDE TIME-COINCIDENT TARGET AND CELESTIAL RADIATION SIGNALS REFERENCED TO ZERO TIME, SAID THIRD AND FOURTH RECEIVING MEANS WHEN THE TARGET IS NEARER SAID ONE LOCATION BEING ARRANGED AND CONSTRUCTED TO PROVIDE TARGET AND CELESTIAL RADIATION SIGNALS DISPLANCED FROM ZERO TIME BY DIFFERENT AMOUNTS THEREBY DEFINING FIRST AND SECOND TIME INTERGALS EXPRESSING THE DEYALS BETWEEN THE PARTICULAR PAIRS OF TARGET AND CELESTIAL RADIATION SIGNALS, FIRST DUALCHANNELS RECORDING MEANS COUPLED TO SAID FIRST AND SECOND RECEIVING MEANS FOR RECORDING THE TIME COINCIDENCE OF THE SINGALS EMERGING THEREFROM, SECOND DUAL-CHANNEL RECORDING MEANS COUPLED TO SAID THRID AND FOURTH RECEIVING MEANS FOR RECORDING THE TIME DISPLANCEMENT OF THE SIGNALS
