A method and system of the present disclosure allow for a more robust detection of GPS satellite ranging signals based on a simultaneous, all-in-view coherent PRN code signal processing scheme rather than acquisition of GPS signals one at a time. Additionally, the method and system may enable 10 dB or more improvement in signal-to-ratio (SNR) acquisition performance of the combined signals when compared to conventional acquisition approaches of acquiring GPS PRN code signals one at a time. The method and system also automatically enables removal of ranging errors common to both the user and base station and minimizes the introduction of multi-path errors into code phase measurements.
