The Mission

In 2003 our unique shareholder (the Italian Ministry of Economy and Finance)

committed Sogei to follow the development of GALILEO

Sogei’s R&D team began working in advanced GNSS technology for Institutional

Applications developments

Since 2004, Sogei is member of the Galileo Services Association


Public Administration Positioning Requirements

• General Public Administrations requirements:� Fixed and Regulated output data formats: High reconfigurability� Security and Anti-fraud: Service Guarantee/Integrit y� High Volumes: Low cost� Independence from proprietary products

• Specific GNSS Applications requirements:� High Accuracy (e.g. Cadastral Surveying)� Service Guarantee, Integrity and Indoor positioning (e.g. Asset Tracking

and Anti-fraud)

� Anti-Jamming and Anti-Spoofing (e.g. Institutional Tracing and Tracking)
