1. A method of acquiring a satellite signal in a GNSS receiver, the method comprising:

  • multiplying a received signal with a hypothesized doppler frequency signal to generate a frequency shifted signal;

    multiplying a PN code sequence signal with the frequency shifted signal to generate a PN wiped signal;

    multiplying a windowing function signal with the PN wiped signal to generate a windowed signal; and

    integrating, coherently, the windowed signal for a first predefined time to generate a coherent accumulated data.
