Abstract
Encoded information means located on an infrastructure to be decoded by sensors located on mobiles, in such a way that these means encode the position they occupy in the infrastructure and allow for a mobile travelling along the same trajectory, provided with the adequate sensor, to read, decode and transform it immediately into information on its exact position in the infrastructure and being characterised by the fact that along the same trajectory described by a mobile it is possible to encode information in the infrastructure by means of different objects presenting dielectric change boundaries or dielectric/metal boundaries at different heights or distances regarding the origin of the onboard sensor, these boundaries being interrogated by a sensor on board the mobile by means of pressure or electromagnetic waves and by measuring the time the waves take to return to the sensor, making it possible to determine the distance at which the reflections occur and in this way to extract the information.
