Satellite-based navigation has become a ubiquitous technology. Global Navigation Satellite System (GNSS) receivers are now found in many consumer products such as smartphones, cameras, laptops and automobiles.  The discussion starts with a review of the three segments of the System; satellites, ground stations and receivers. From there, the various influences on satellite orbits are examined along with the errors these influences produce. Operational topics covered include trilateration, ranging estimation and error sources, PRN code, time error correction, navigation equations, signal spectra and BOC Modulation. Navigation Systems from Russia, China, India and the EU are also reviewed.

In the concluding segment, a typical GNSS receiver architecture is reviewed with a focus on RF front-end considerations and baseband processing. Following is a discussion on recent advances in an integrated solution that includes LNA, ADCs and fractional-N PLL which supports GPS/Galileo/GLONASS/BeiDou L1/G1/E1/B1.
