The techniques to detect and mitigate the false reacquisition in a global satellite navigation receiver are disclosed. The false reacquisition due to frequency side-lobes and code autocorrelation secondary lobes are considered for mitigation. A set of two threshold values is used to detect correct reacquisition and reject false reacquisition. While the reacquisition of the signal is straight forward when the correlation is clear with the power above the first threshold, it is not so clear when the power is between two thresholds. So a further search for the maximum power among the retained dwells results in correct reacquisition. The search range depends upon the signal blockage interval and receiver dynamics. The feedback from navigational solution may be used to determine the search range both in frequency and code phase. In the case of frequency side-lobes, which occur only at specified frequency components, these frequencies are tested for maximum power response. The code side-lobes have similar characteristics and can be distinguished by the actual peak.
