Abstract
An apparatus for processing a radio navigation signal. The apparatus has a first correlator correlating a first signal component with a first code, providing a first output, and having a carrier frequency and data. The apparatus also has a second correlator is configured to correlate a second signal component with a second code, providing a second output, and being different from the first code, the second signal component having the same carrier frequency as the first signal component and the same data as the first signal component. Each of real (I) and imaginary (Q) parts of the second output are delayed relative to respective parts of the first output such that the data on the second signal component is delayed with respect to the data on the first signal component, providing a delayed second output. The processor processes the outputs, their data being aligned to provide frequency information about the carrier.
