Localization is one of the most relevant problems in mobile robotics, and is basis for other robot functionalities, such as mapping, path planning and motion controlling. Currently there are devices like GPS, odometer and digital compass that provide the position with high accuracy. However, these sensors can accumulate errors over time that prejudice the robot navigation. These errors are originated by external disturbance, as example, discontinuity in the GPS signal caused by building obstruction. In order to fix these failures, there are methods that incorporate into the localization system, information regards the sensor data (cameras or laser range finders) matching with the environment map. For this, it is necessary a map building step, that most of times are impractical for areas of city sizes. To overcome this problem, the actual project proposes the employment of satellite map, which is available freely by several sources, moreover, has high resolution and precise longitude and latitude information. The localization system will be deployed in real vehicles to obtain its localization relative to this map while driving in urban environments. (AU)
