Abstract:
Embodiments of the invention provide a method for detecting false peaks in a Global Navigation Satellite System (GNSS) having a power control circuit, a measurement engine, and position engine. An estimated pseudorange is filtered over time. A false peak is declared if the filtered pseudorange error is greater than a threshold.
