Abstract

A system and a method are disclosed for verifying a Global Navigation Satellite System (GNSS) space vehicle (SV) signal. An extremely weak frame synchronization (EWFS) verification process is run on a current SV signal with respect to another verified SV signal. An indication is set that frame synchronization for the current SV signal is complete after full frame synchronization occurs based on a peak EWFS correlation value of the current SV signal being equal to or greater than a first threshold. The indication may be set early based on the peak EWFS correlation value of the current SV signal being greater than a second threshold value that is greater than the first threshold. Tracking of the current SV signal may be terminated early based on the peak EWFS correction value of the current SV signal being less than a third threshold that is less that the first threshold.
