Abstract
Systems and methods for avoiding non-linear behavior of conventional early-minus-late correlator-based code loop discriminators. The present invention provides a model of correlator behavior that takes into account whether both correlators are on the same side of the correlation peak or they straddle the peak. The result is a piecewise solution that can be stitched together quite readily to produce an extended range of linear response, thereby improving the pull-in capability of GPS code loops when closely spaced correlators are being used.
