Concerned About GNSS Inaccuracy? Expand Your Constellations


要約: One of the vulnerabilities of Global Navigation Satellite Systems (GNSS) is the receiver’s inability to get a \"good read\" from a compromised satellite signal. This uncertainty is usually due to a lack of a direct line-of-sight. This application note identifies the constellations that rotate around the earth, then proceeds to a discussion of the GNSS receiver’s interference sources. This thorough constellation and error source examination concludes with a description of receiver architecture that significantly reduces direct line-of-sight errors by accepting multi-band and multi-constellation signals.
