A system architecture for a receiver to process multiple signals on a common carrier frequency from a satellite. The receiver is arranged such that the receiver receives input data transmitted from the satellite. A pilot signal is tracked from the input data using a correlation channel, and a data signal is tracked from the input data using a data code generator operatively connected to the correlation channel. In one embodiment of the invention, the data signal generator creates replica code for the data signal. In another embodiment of the invention, the system can switch between the data signal generator and pilot signal generator based upon the signal-to-noise ratio of the incoming signal.
