Method and system for determining position from suppressed carrier signals transmitted by satellites in which a digital representation of the satellite signals is sampled and distributed for simultaneous measurement in synchronous parallel circuits. The phases of suppressed carriers implicit in the signals...http://www.google.es/patents/US5619212?utm_source=gb-gplus-sharePatente US5619212 - System for determining position from suppressed carrier radio waves
