Paper Abstract

The current Global Positioning System signal tracking techniques are vulnerable to bit transitions in the baseband navigation signal. We present new signal tracking techniques as lock discriminators in carrier frequency and code delay domains derived within the framework of wavelet theory that are robust to these bit transitions. We then present the performance analysis of the proposed lock discriminators comparatively with currently used techniques on real data.
