Galileo Services

GALILEO wil provide four basic satellite-only services. These services will be provided worldwide and independently from other systems by combining Galileo signals-in-space:

• GALILEO Open Service (OS) - This service results from a combination of open signals, free of user charge, and provides superior position and timing performance compared to other GNSS systems.

• GALILEO Safety of Life (SoL) service - Will be offered and guaranteed to the critical transport community, e.g. aviation, maritime, etc., delivering enhanced performance that includes the provision of the integrity function, i.e. a warning of system malfunction that will reach the user in a given alarm time. This service will be certified against applicable standards and performance, for example the SBAS standards of the International Civil Aviation Organisation (ICAO) in 2009.

• GALILEO Commercial Service (CS) - Provides access to two additional signals, to allow for a higher data throughput rate and to enable users to improve accuracy. The signals are encrypted. A service guarantee is envisaged for this service.

• GALILEO Public Regulated Service (PRS) - provides position and timing to specific users requiring a high continuity of service, with controlled access. Two PRS navigation signals with encrypted ranging codes and data will be available.

In addition, GALILEO support to search and rescue services represents Europe's contribution of to the international COSPAS-SARSAT co-operative effort on humanitarian search and rescue activities. GALILEO is to play an important part of the Medium Earth Orbit Search and Rescue system (MEOSAR)
