Abstract
A satellite navigation device including a flexible RF receiver is described. The receiver receives a signal that includes at least one spread-spectrum signal from a first satellite. The receiver has at least a first channel that includes at least two sub-channel circuits. Each sub-channel circuit has at least a first signal generator and a first mixer to receive a respective frequency band in at least the one spread-spectrum signal from the first satellite. The first signal generator provides a respective first signal, having a respective first carrier frequency, to down convert at least a portion of the signal, using the first mixer, to an intermediate frequency that is common to the two sub-channel circuits.
