Original Abstract Submitted
An apparatus, method, and portable navigation device for determining a PRN code to correlate with a ranging code on a satellite-based navigation system receiver are provided. An example satellite-based navigation system receiver may include a plurality of tracking channels, wherein each tracking channel of the plurality of tracking channels is configured to generate a pseudo-random code based at least in part on a first code value from a first position in a code sequence and a second code value from a second position in the code sequence. The example satellite-based navigation system receiver may further comprise a read-only memory configured to store the code sequence. A second plurality of the plurality of tracking channels may be configured to receive the first code value and the second code value from the read-only memory.
