European Project GALA was a preliminary study on 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 provide high-precision positioning and time
information with global coverage.
The Galileo system will offer different service levels for
professional users, the mass market, and emergency, rescue
& safety applications, distinguished by the localisation,
carried out with respect to global, regional or local database.
The Galileo system is subdivided into the global and regional
components, which include: the space segment (MEO and GEO
satellites), the terrestrial segment, comprising of the
terrestrial stations enhancing the system performance, and
the end-user segment.
This system will integrate the European Geostationary Overlay
Services (GNSS-1 EGNOS) with other existing systems, in
a way to provide hybrid terminals incorporating different
types of sensors.
The participation of INOV was at the level of terminal equipment,
in terms of analysis of requirements and the functional
concept of the navigation receiver for the mass-market segment.
Costs and performance were specified and comparative technological
analysis with respect to the GPS receivers was provided
for each application type.
