Geolocation Project

By using our range and synch technology to accurately determine pointing angles from one satellite to its neighbor, the need for tracking on each craft in a constellation of satellites becomes less needed. If the position of one craft is known from other tracking systems such as GPS or Star Trackers, then the position of the rest of the craft in communication would be known. Since the pointing information is embedded in the signal of the LaserFire system, this is just a matter of integrating the information into new computational models. These models are a combination of Euler Rotations and a Quazi-Newton Method to solve a nonlinear system of equations relating the position and attitude of each craft with the pointing angles of the laser system. By using this method, the craft would only require the use of other tracking systems while the constellation is out of communication. If any loop of communication between multiple craft is completed, then the system would be able to give accurate locations relative to the primary craft.
