The authorities responsible for the European geographic positioning system, the European Navigation and Satellite Agency (GNSS), confirmed in a statement that the Galileo system is out of service since 11 July but gave no explanation as to why.

The Agency also avoid saying a date for the restart of the system. "Until further notice" and "as soon as possible" were some of the ambiguous terms used in the official note.

Later some officials referred, without specifying, to a technical problem in the terrestrial infrastructure that has already been identified.

The geographical location devices currently in use are the GPS, North American, with 32 satellites, the Russian Glonass, with 24 satellites and the Chinese Beidou, with three. However the European Galileo, which has 26 satellites, is open to use in any mobile or navigation device in the European market, is currently the highest precision, with one meter, compared to 50 GPS.

The Galileo project suffered delays and obstacles from the beginning due to pressures from some EU states and the US, through NATO, both because of its technological and economic implications and because of its high precision, given that the GPS version the US use in the market is far below in precision than its original version, exclusively used by the US Army, under the argument of "national security".

All experts agree that it is not usual for a problem involving a complete network of satellites stop working, so the silence of the GNSS on the subject leaves in the air numerous doubts about the current "technical problem" of the Galileo system .
