		<abstract>The use of unmanned aerial vehicles (UAVs) has increasingly in civilian and military applications. Normally the military applications are often realized in inhospitable environments, whether for geographical reasons or war conflicts. In order to fulfill this type of mission, it is important that the UAV be provided with an autonomous navigation system so that it can fulfill its flight planning without the need for human intervention during the whole period. The main autonomous navigation systems currently used are based on GNSS (Global Navigation Satellite System), whose technology is not of Brazilian domain. An alternative form is the development of an autonomous navigation system based on images. Due to the great complexity of this system, it is necessary to develop several tools that aid in the autonomous navigation. This work aims to develop a navigation aid based on shadow identification of an image or a sequence of images and the analysis of the data of the time and the location of the image, determining the direction of flight (Rumo) that the aircraft is flying, making any necessary corrections. The system was developed in C ++ language. Preliminary results indicated a great potential for the use of shadow identification in autonomous navigation aid systems.</abstract>
