Claim 1
Independent Claim
62 words
A METHOD OF DETERMINING ON BOARD A VEHICLE THE SIMULTANEOUS RELATIVE BEARINGS OF FORE AND AFT RANGE STATIONS WHICH COMPRISES RADIATING FROM SAID RANGE STATIONS SIGNALS HAVING A TIMELOCKED CHARACTERISTIC, AND COMPARING THE TIME-RELATIONSHIP OF SAID SIGNALS AS RECEIVED AT LATERALLY SPACED POINTS BETWEEN OR ON OPPOSITE SIDES OF THE VEHICLE TO DETERMINE THE RELATIVE BEARING OF EACH OF SAID RANGE STATIONS.
Claim 2
Independent Claim
124 words
A METHOD OF DETERMINING ON BOARD A VEHICLE ITS LATERAL OFFSET WITH RESPECT TO THE BASE LINE BETWEEN FORE AND AFT RANGE STATIONS WHICH COMPRISES RADIATING FROM SAID RANGE STATIONS HAVING A TIMELOCKED CHARACTERISTIC, COMPARING THE TIME RELATIONSHIP OF THE SIGNALS FROM SAID RANGE STATIONS AS RECEIVED AT LATERALLY SPACE POINTS BETWEEN OR ON OPPOSITE SIDES OF SAID VEHICLE TO PROVIDE RELATIVE BEARING INFORMATION WITH RESPECT TO EACH OF SAID STATIONS, COUNTING THE SUCCESSIVE OCCURRENCES OF A PREDETERMINED TIME-RELATIONSHIP BETWEEN THE SIGNALS OF SAID STATIONS AS RECEIVED ON THE VEHICLE TO PROVIDE DISTANCE INFORMATION, AND COMBINING THE DISTANCE INFORMATION AND THE ALGEBRAIC SUM OF THE BEARING INFORMATION FOR EACH OF SAID STATIONS TO DETERMINE THE LATERAL OFFSET OF THE VEHICLE FROM SAID BASE LINE.
