System for bounding the radius coordinate of an orbiting vehicle
First Claim
1. IN A SPACE NAVIGATION SYSTEM FOR AN ORBITING VEHICLE, SAID NAVIGATION SYSTEM DEFINING THE ORBIT OF SAID VEHICLE WITH RESPECT TO A REFERENCE BODY IN A COORDINATE SYSTEM IN WHICH SAID COORDINATES ARE RANGE ANGLE, CROSS RANGE ANGLE AND THE RADIUS MEASURED ALONG A LINE CONNECTING SAID VEHICLE WITH THE CENTER OF SAID REFERENCE BODY, COMPRISING MEANS FOR PRODUCING A VEHICLE ACCELERATION SIGNAL FOR EACH OF SAID COORDINATES, FIRST INTEGRATING MEANS FOR INTEGRATING EACH SAID VEHICLE ACCELERATION SIGNAL INTO A VEHICLE VELOCITY SIGNAL FOR EACH SAID COORDINATE, SECOND INTEGRATING MEANS FOR INTEGRATING EACH SAID VEHICLE VELOCITY SIGNAL INTO A VEHICLE INDICATED POSITION SIGNAL FOR EACH SAID COORDINATE, MEANS FOR PRODUCING A VERTICAL SIGNAL INDICATIVE OF THE LOCAL VERTICAL OF SAID VEHICLE WITH RESPECT TO SAID REFERENCE BODY, MEANS RESPONSIVE TO SAID VERTICAL SIGNAL FOR PRODUCING SIGNALS INDICATIVE OF THE MEASURED POSITION OF SAID VEHICLE RELATIVE TO SAID RANGE ANGLE AND CROSS RANGE ANGLE COORDINATES, MEANS FOR COMPARING SAID MEASURED VEHICLE POSITION SIGNALS RELATIVE TO SAID RANGE ANGLE AND CROSS RANGE ANGLE COORDINATES WITH SAID INDICATED VEHICLE POSITION SIGNALS RELATIVE TO SAID RANGE ANGLE AND CROSS ANGLE COORDINATES AND PRODUCING THEREFROM AN ERROR SIGNAL FOR EACH OF SAID RANGE ANGLE AND CROSS RANGE ANGLE COORDINATES,
