Abstract
A method includes receiving a respective channel signal from a respective satellite encoded with a pseudorandom number (PN) sequence. The method includes, for the respective channel signal: generating and aggregating intermediate results for a plurality of epochs of a single pseudorandom number (PN) sequence period of the PN sequence, including: for each respective epoch of the plurality of epochs, analyzing samples of the respective channel signal using a discrete Fourier transform (DFT), to produce an intermediate result for the respective epoch; and aggregating the intermediate results for the plurality of epochs to produce a DFT correlation result. The method includes processing the DFT correlation result to produce a code phase correction for the respective channel and, in accordance with the code phase correction, computing position and velocity estimates for the mobile object; and performing a navigation function for the mobile object.
