Wong's angles to determine trajectories of objects

A method of locating a GPS satellite relative to earth, comprising the steps of:

• sensing the satellite through electro-magnetic or electro-optical means;
• selecting three GPS ground stations on earth, each ground station having unique coordinates, relative to the earth's center, of altitude, longitude and latitude;
• processing, by three-dimensional coordinate geometry, distances (a) between the three GPS ground stations and (b) between the center and each of the three ground stations;
• calculating Wong's angles for each of the GPS ground stations to the satellite;
• obtain, by trigonometry, a range from the satellite to each of the ground stations, the range being defined in terms of the Wong's angles and of the distances;
• obtain a position vector defined by the Wong's angles and the distances;
• determining an altitude of the satellite by taking a difference between the position vector and the earth's radius;
• defining, by Newton's gravitational law, a gravitational acceleration of the satellite in terms of the Wong's angles;
• determining satellite velocity by taking a first derivative of the position vector with respect to time;
• determining satellite acceleration by taking a second derivative of the position vector with respect to time;
• predicting the trajectory of the satellite in terms of a trajectory solid angle;
• and
• locating the satellite at a predetermined time following the step of sensing the satellite.
