European Project GALA was the prior study of the global architecture of the Galileo system, realised by several companies and institutes in the European Community, for ESA (European Space Agency).

The Galileo System (GNSS-2, Global Navigation Satellite System) is a satellite navigation system led by Europe. The system will offer positioning and time, with global coverage.

The Galileo System will offer different service levels for professional users, for the mass market, and for emergency, rescue and safety applications.

The Galileo system is divided into a global and a regional component, which includes the space segment (MEO and GEO satellites), the terrestrial segment (including terrestrial stations for performance increase) and the user segment.

This system will integrate the previous European GNSS-1 System EGNOS (European Geostationary Overlay Services), together with the existing systems, in a way to form hybrid terminals incorporating other sensors.

The participation of INOV was at the level of terminal equipment, in terms of analysis of requirements and of the functional concept of the navigation receiver, for the mass-market segment. For each application type was done a cost, performance and comparison analysis with GPS receivers in technological terms.
