1. A GPS (Global Positioning System) collision avoidance apparatus comprising:

  • (a) receiving means for continuously receiving radio frequency carrier signals containing GPS data from an external source which generates said GPS data;

    (b) first processing means connected to said receiving means to receive an RF (radio frequency) electrical signal which contains said GPS data, said first processing means processing said GPS data calculating current position data for said collision avoidance apparatus including a latitude, a longitude and an elevation for said collision avoidance apparatus;

    (c) time data generating means for generating time data;

    (d) second processing means connected to said first processing means to receive said current position data and said time data generating means to receive said time data, said second processing means performing calculations on said current position data and said time data to determine position and motion dynamics data for said collision avoidance apparatus, said position and motion dynamics data including current position, direction of motion, velocity and acceleration data for said collision avoidance apparatus and a user of said collision avoidance apparatus;

    (e) memory means for storing the locations for said stationary obstacles which are in a path of said user of said collision avoidance apparatus, said memory means providing location data indicative of the locations of said stationary obstacles in the path of said user; and

    (f) third processing means connected to said second processing means to receive said position and motion dynamics data and said memory means to receive said location data, said third processing means comparing said location data for said stationary objects in the path of said user with said current position, direction of motion, velocity and acceleration data for said user of said collision avoidance apparatus, said third processing means determining a distance between said user of said collision avoidance apparatus and a closest one of said stationary obstacles in the path of said user and then calculating a probability for a collision between said user and the closest one of stationary obstacles in the path of said user.
