133. GALILEO, unlike EGNOS, is a <strong>global</strong> stand-al<strong>on</strong>e system. It will be <str<strong>on</strong>g>the</str<strong>on</strong>g> first civil<strong>satellite</strong> positi<strong>on</strong>ing and navigati<strong>on</strong> system under c<strong>on</strong>trol <str<strong>on</strong>g>of</str<strong>on</strong>g> European public authorities that willbe operated by a private entity.134. GALILEO will provide <str<strong>on</strong>g>the</str<strong>on</strong>g> required stability for European investments in this area and inindustries around <str<strong>on</strong>g>the</str<strong>on</strong>g> world in innovative market segments. GALILEO will also <str<strong>on</strong>g>of</str<strong>on</strong>g>fer, al<strong>on</strong>gsidean open service similar to <str<strong>on</strong>g>the</str<strong>on</strong>g> GPS civilian service, new features to improve and guaranteeservices, <str<strong>on</strong>g>the</str<strong>on</strong>g>reby creating <str<strong>on</strong>g>the</str<strong>on</strong>g> c<strong>on</strong>diti<strong>on</strong>s for resp<strong>on</strong>ding to obligati<strong>on</strong>s imposed by regulated,safety <str<strong>on</strong>g>of</str<strong>on</strong>g> life or commercial applicati<strong>on</strong>s. GALILEO will be compatible and interoperable witho<str<strong>on</strong>g>the</str<strong>on</strong>g>r <strong>systems</strong> at user level to facilitate <str<strong>on</strong>g>the</str<strong>on</strong>g>ir combined use all over <str<strong>on</strong>g>the</str<strong>on</strong>g> world. For higherreliability, comm<strong>on</strong> failure modes between EGNOS and GALILEO <strong>on</strong> <strong>on</strong>e hand, and GALILEOand GPS <strong>on</strong> <str<strong>on</strong>g>the</str<strong>on</strong>g> o<str<strong>on</strong>g>the</str<strong>on</strong>g>r hand, will be prevented. Special attenti<strong>on</strong> has been given to <str<strong>on</strong>g>the</str<strong>on</strong>g> securityaspect <str<strong>on</strong>g>of</str<strong>on</strong>g> GALILEO, with <str<strong>on</strong>g>the</str<strong>on</strong>g> aim to protect its infrastructure and to prevent <str<strong>on</strong>g>the</str<strong>on</strong>g> potential misuse<str<strong>on</strong>g>of</str<strong>on</strong>g> its signals.System descripti<strong>on</strong>135.

Four navigati<strong>on</strong> services and <strong>on</strong>e service to support Search and Rescue operati<strong>on</strong>s havebeen identified to cover <str<strong>on</strong>g>the</str<strong>on</strong>g> widest range <str<strong>on</strong>g>of</str<strong>on</strong>g> user needs, including pr<str<strong>on</strong>g>of</str<strong>on</strong>g>essi<strong>on</strong>al users, scientists,mass-market users, safety <str<strong>on</strong>g>of</str<strong>on</strong>g> life and public-regulated domains. Following c<strong>on</strong>sultati<strong>on</strong>s withvarious user groups and internati<strong>on</strong>al standardisati<strong>on</strong> organizati<strong>on</strong>s such as ICAO and IMO, <str<strong>on</strong>g>the</str<strong>on</strong>g>following set <str<strong>on</strong>g>of</str<strong>on</strong>g> GALILEO Satellite-<strong>on</strong>ly services will be provided worldwide:• The Open Service results from a combinati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> basic signals, free <str<strong>on</strong>g>of</str<strong>on</strong>g> user chargeto <str<strong>on</strong>g>the</str<strong>on</strong>g> general public. It provides positi<strong>on</strong> and timing performances competitive with<str<strong>on</strong>g>the</str<strong>on</strong>g> two o<str<strong>on</strong>g>the</str<strong>on</strong>g>r GNSS <strong>systems</strong>.• The Safety <str<strong>on</strong>g>of</str<strong>on</strong>g> Life Service is a service <str<strong>on</strong>g>of</str<strong>on</strong>g> a very high quality for safety-criticalapplicati<strong>on</strong>s, such as aviati<strong>on</strong> and maritime transport. It will improve <str<strong>on</strong>g>the</str<strong>on</strong>g> OpenService by providing quick warnings (integrity) to <str<strong>on</strong>g>the</str<strong>on</strong>g> user if it fails to meet safetymargins <str<strong>on</strong>g>of</str<strong>on</strong>g> accuracy. Guarantees are c<strong>on</strong>sidered for this service.• The Commercial Service facilitates <str<strong>on</strong>g>the</str<strong>on</strong>g> development <str<strong>on</strong>g>of</str<strong>on</strong>g> pr<str<strong>on</strong>g>of</str<strong>on</strong>g>essi<strong>on</strong>al applicati<strong>on</strong>s and<str<strong>on</strong>g>of</str<strong>on</strong>g>fers enhanced performance compared with <str<strong>on</strong>g>the</str<strong>on</strong>g> Open Service, particularly in terms<str<strong>on</strong>g>of</str<strong>on</strong>g> higher data rates, service guarantees and accuracy.• The Public Regulated Service (PRS) provides positi<strong>on</strong> and timing to publicauthorities resp<strong>on</strong>sible for civil protecti<strong>on</strong> and security. Two PRS navigati<strong>on</strong> signalswith encrypted ranging codes and data will provide a higher level <str<strong>on</strong>g>of</str<strong>on</strong>g> protecti<strong>on</strong>, e.g.against interference or jamming.28
