Bilateral cooperation on usage of GPS and Galileo

US: The United States (US) and the European Union (EU) announced a bilateral cooperation between the US GPS and the European Galileo, global navigation satellite system (GNSS).

The agreement marks the conclusion of an initial phase of consultations for user interoperability and enhanced performance of combined GPS and Galileo receivers performance under the 2004 agreement on the promotion, provision and use of Galileo and GPS and related applications. The consultations under the fore mentioned agreement discuss matters regarding a bilateral cooperation in the use of GNSS.

A working group was designed by the two involved parties to complete an assessment of the global, combined performance for GPS Space-Based Augmentation System (SBAS) receivers using the European Geostationary Navigation Overlay Service (EGNOS) and the GPS Wide Area Augmentation System (WAAS) supporting safety-of-life applications.

The results showed an improved availability for a wide range of aviation services in both hemispheres and significantly improved robustness to GPS satellite outages. The group also completed a study that compares GPS, Galileo and a combined performance for three types of receivers.

The combined GPS/Galileo provided significant improvements especially in partially obscured environments, where buildings, trees or terrain block large portions of the sky. For such environments, the group recommended the usage of dual-frequency receivers.

Through these activities, the US and the EU demonstrate the close cooperation since 2004 to ensure that GPS and Galileo are compatible for the benefit of end users around the world. Both the US and the EU will continue to work together on these issues in order to raise the state-of-the-art in navigation positioning, and timing services for users worldwide.
