The Galileo is a space-based global navigation satellite system (GNSS) that provides reliable positioning, navigation, and timing services to users on a continuous worldwide basis freely available to all.

Galileo phases

The Galileo program is Europe's initiative for a state-of-the-art global satellite navigation system, providing a highly accurate, guaranteed global positioning service under civilian control.[1] While providing autonomous navigation and positioning services, the system established under the Galileo program will at the same time be interoperable with other GNSS systems such as GPS and GLONASS. The system will consist of 30 satellites, to be deployed in a staggered approach, and the associated ground infrastructure.[2]

Based on the award of the contracts for the first order of satellites, the launch services, the system support services and the operations, the European Commission announced the Initial Operational Capability (IOC) with three initial services to be provided in 2014/2015: an initial Open Service, an initial Public Regulated Service and an initial Search and Rescue Service.[3] At this stage, accuracy and availability will not yet have reached their optimum level, the Safety-of-Life Service and the Commercial Service will be tested and will be provided as the system reaches full operational capability with the 30 satellites.[4]

The definition phase and the development and In-Orbit Validation phase of the Galileo program were carried out by the European Space Agency (ESA) and co-funded by ESA and the European Union. The Full Operational Capability phase of the Galileo program is fully funded by the European Union and managed by the European Commission. The Commission and ESA have signed a delegation agreement by which ESA acts as design and procurement agent on behalf of the Commission.

The Galileo program has been structured according to three main phases:[5]

  • In-Orbit Validation (IOV) phase:
The IOV phase consists of qualifying the system through tests and the operation of two experimental satellites and a reduced constellation of four operational satellites and their related ground infrastructure.
The two experimental satellites were launched in respectively December 2005 and April 2008. Their purpose was to characterize the Medium-Earth Orbit (MEO) environment (radiations, magnetic field etc) and to test in such environment the performance of critical payload technology (atomic clocks and radiation hardened digital technology). They also provide an early experimental signal-in-space allowing securing the frequency spectrum required for Galileo in accordance with WRC RNSS allocations. The launch of the first two operational satellites is scheduled for end of 2011.
  • Initial Operational Capability (IOC) phase:
The IOC stage will be the partial commissioning of the ground and space infrastructure as from 2014-2015 and the provision of the open service, the search and rescue service and the PRS. While this first stage will be sufficient to test the services it should nonetheless be as short as possible, because it will not allow the system's full potential to be exploited and will not meet the requirements of all users.
  • Full Operational Capability (FOC) phase:
The FOC phase consists of the deployment of the full system which will consist of 30 satellites, control centres located in Europe and a network of sensor stations and uplink stations installed around the globe. Galileo's Full Operational Capability (FOC) should be achieved in 2019-2020, in a staggered approach from the IOC phase. It might change, depending on availability of financing, technical problems and industrial performance.
