Claim 1
Independent Claim
230 words
AN INERTIAL NAVIGATION SYSTEM COMPRISING A PLATFORM WITH MUTUALLY PERPENDICULARL X,Y, AND Z AXES, SAID X AXIS ADAPTED TO BE ALIGNED WITH NORTH, SAID Y AXIS ADAPTED TO BE ALIGNED WITH EAST-WEST DIRECTION, AND SAID Z AXIS ADAPTED TO BE ALIGNED WITH VERTICAL, AN ACCELEROMETER ON SAID PLATFROM POSITIONED TO MEASURE THE ACCELERATION OF SAID PLATFORM ALONG SAID X AXIS, AN INTEGRATING MEANS TO INTEGRATE THE OUTPUT SIGNAL OF SAID ACCELEROMETER TO PRODUCE A SIGNAL REPRESENTING THE VELOCITY OF SAID PLATFORM ALONG SAID X AXIS, DOPPLER RADAR MEANS FOR GENERATING A SIGNAL REPRESENTATIVE OF THE VELOCITY OF SAID PLATFORM ALONG SAID X AXIS RELATIVE TO THE EARTH, VELOCITY COMBINING MEANS TO PRODUCE A SIGNAL VARYING IN ACCORDANCE WITH THE DIFFERENCE BETWEEN THE VELOVITY REPRESENTED BY THE OUTPUT SIGNAL OF SAID INTEGRATING MEANS AND THE VELOCITY OF SAID PLATFORM ALONG SAID X AXIS DETERMINED FROM SAID DOPPLER SIGNAL, MEANS RESPONSIVE TO THE OTUPUT SIGNAL OF SAID VELOCITY COMBINING MEANS TO PIVOT SAID PLATFORM ABOUT SAID Z AXIS OF REDUCE THE OUTPUT SIGNAL FO SAID VELOCITY COMBINING MEANS, INCLUDING MEANS TO ADDITIVELY COMBINE WITH THE OUTPUT SIGNAL OF SAID ACCELEROMETER APPLIED TO THE INPUT OF SAID INTEGRATING MEANS A SIGNAL REPRESENTING THE RATE AT WHICH SAID PLATFORM IS BEING PIVOTED ABOUT SAID Z AXIS IN RESPONSE TO THE OUTPUT SIGNAL OF SAID VELOCITY COMBINING MEANS TIMES THE VELOCITY ALONG SAID Y AXIS.
