Description: The advent of GPS has afforded the aerospace controls engineer a powerful, new means of controlling air      vehicles This work explores a new method of designing and implementing controllers and guidance systems      for autonomous control of air vehicles utilizing a GPS integrated guidance, navigation and control system.      This is a subject of considerable interest when realizing controllers to track reference trajectories given in an      inertial reference frame. The design, implementation, and dynamic simulation of a precise tracking trajectory      controller for an Unmanned Air Vehicle (UAV) is presented. This design provides a natural conversion of      commands and other measured outputs (such as GPS signals) from an inertial reference frame to a      body-fixed reference frame. This achieves automatic recruiting of the actuators while preserving the      properties of the original design (linearization principle).
