Abstract

Se revela un método y un sistema para calibrar informacion de tiempo no calibrada dentro de un terminal movil 101. El terminal tiene un receptor 203 capaz de recibir senales de las cuales la informacion de tiempo calibrada llevada por un sistema calibrado (un sistema de posicionamiento satelital) puede ser extrana, y un receptor 200 capaz de recibir senales de las cuales informacion de tiempo no calibrada llevada por un sistema estable no calibrado (un sistema de comunicacion celular) puede ser extraída. El desplazamiento de tiempo entre la informacion de tiempo calibrada extraída del sistema calibrado y la informacion de tiempo no calibrada extraída del sistema estable no calibrado es determinada en una primera posicion de terminal donde las senales provenientes del sistema estable no calibrado están disponibles, los tiempos de propagacion de las senales provenientes del sistema estable no calibrado son conocidos o determinados, y las senales provenientes del sistema calibrado están disponibles. La informacion de tiempo no calibrada extraída de senales de un sistema estable no calibrado recibidas en una segunda posicion de terminal, es calibrada desde tiempos de propagacion conocidos o determinados de las senales provenientes del sistema estable no calibrado en la segunda posicion de terminal y el desplazamiento de tiempo que ha sido determinado.
