Methods of measuring phase angle and decoding a pseudo-random noise (PRN) code by applying High Resolution Correlators, having three or more correlators signals, where at least two signals, or multiples of two, are equally distanced advanced or delayed signals from the PRN signal with the option of
Methods of measuring phase angle and decoding a pseudo-random noise (PRN) code by applying High Resolution Correlators, having three or more correlators signals, where at least two signals, or multiples of two, are equally distanced advanced or delayed signals from the PRN signal with the option of one signal substantially in sync with the PRN signal. A phase tracking error is computed when measuring phase angle or adjusting the relative timing difference by adjusting the phase of the locally generated PRN signals when the error signal has a non-zero magnitude, in a manner to drive said error signal to zero when decoding the PRN code.
