GNSS-based traffic monitoring
Global Navigation Satellite System (GNSS) probe -based traffic information services are now commonly used across the world. For the purpose of this chapter, we will use the term `GNSS' stands for Global Navigation Satellite System which is a standard generic term for satellite navigation systems. GNSS includes all global navigation systems, including GPS, GLONASS, Galileo and other regional systems. GNSS data is highly accurate, and this service provides a scalable delivery platform that will continue to improve as more data become available.
