Abstract
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 are combined in a time series of measurements with phase data from a second receiver to determine position.
