Abstract:
A collision Avoidance System for preventing the collision of moveable craft relative to the earth's surface where there is a common referenced multi dimensional position and motion determining system in operation comprising:position determining means in said movable craft for determining data parameters of position, velocity, acceleration and time of said craft relative to the Earth's surface;CPU means in said craft coupled to said position determining means for continuously storing said data parameters at time spaced intervals and calculating 2.sup.nd order motion path coefficients for transmission in time spaced data packets and for storing craft identification indicia and for storing craft operating parameters and limitations;digital transmission means coupled to said CPU means for transmitting said time spaced data packets containing the craft identification indicia, the unique message type identification, the motion path coefficients, and the time data in digital format to remote receiver means;digital receiver means coupled to said CPU means for receiving and storing said time spaced data packets containing the identification indicia, the unique message type identification, motion path coefficients, and the time data in digital format from remote transmitter means;said CPU means having programming instructions so as to be responsive to said data parameters for calculating collision potential between said aircraft and remote object using aircraft motion path data, and data received from remote transmitter means; andAudio means coupled to said CPU means in said craft for notification to craft operator of collision potential and/or evasive maneuver instructions.
