Abstract
A method and apparatus are provided for detecting GNSS signal lock. An example method includes tracking a plurality of signals received from a respective plurality of satellites in the GNSS, and calculating an individual frequency spectrum for each tracked signal in the plurality, to produce a plurality of individual frequency spectra. The example method further includes combining one or more values from several of the individual frequency spectra, to produce one or more combined values; and detecting an ensemble signal lock condition based at least in part on the one or more combined values.
