Galileo Services

Galileo, once fully operational, will offer four high-performance services worldwide:

Open Service (OS) Galileo open and free of charge service set up for positioning and timing services.

Commercial Service (CS) A service complementing the OS by providing an additional navigation signal and added-value services in a different frequency band. The CS signal can be encrypted in order to control the access to the Galileo CS services.

Public Regulated Service (PRS) Service restricted to government-authorised users, for sensitive applications that require a high level of service continuity.

Search and Rescue Service (SAR) Galileo will be an important element of MEOSAR (Medium Earth Orbit Search and Rescue system), and thus a key contributor to Cospas-Sarsat, the international satellite-based search and rescue distress alert detection and information distribution system. Galileo satellites will receive emergency beacons carried on ships, planes or people and send them back to national rescue centres. Also a feedback to a beacon could be sent, being this exclusive with Galileo.
