GNSS & GPS Systems

GNSS stands for Global Navigation Satellite System, and is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. This term includes e.g. the GPS, GLONASS, Galileo, Beidou and other regional systems.

The term GPS is specific to the United States’ GNSS system, the NAVSTAR Global Positioning System. As of 2013, the United States NAVSTAR Global Positioning System (GPS) and the Russian GLONASS are the only fully operational GNSS, and accordingly account for the bulk of UNAVCO’s available equipment and project support.

Trimble GNSS GPS receivers are a flexible positioning solution for productive and accurate GIS data collection. With the freedom to choose from a range of configurations, Trimble GNSS receivers provide timely and accurate data for decision-making and integrate seamlessly with industry-standard GIS systems and professional GIS data collection workflows.
