Abstract
A method for directional control of a drilling system, having steps of using an inclination and azimuth hold system to develop a path to be followed by the drilling system, wherein the inclination and azimuth hold system calculates an inclination angle of a tool face and an azimuth angle of the tool, generating a set point attitude to establish the path to be followed by the drilling system and controlling the drilling system to drill along the path obtained by the inclination and azimuth hold system.
