Why is satellite navigation important to the EU?

Today, the positioning and timing signals provided by satellite navigation systems are used in many critical areas of the economy, including effective road, sea and air traffic management, in-car navigation, electronic trading as well as mobile phone networks and power grid synchronisation.

Satellite navigation applications are now numerous and varied and play key roles both in business and in the daily lives of citizens and communities. Independence in this area is important to the EU's economy: in 2011 it was estimated that already 6-7% of Europe's GDP, or €800 billion, relied on satellite navigation applications. European access to reliable and accurate satellite navigation services is therefore essential.

The satellite navigation sector also provides an enormous market, offering the potential to generate growth and create jobs in the EU. Like the internet, a global navigation satellite system is a service enabler rather than a standalone service. It acts as a catalyst for economic activities, leading to the creation of growth and jobs in a wide range of domains, such as space, receivers and applications. In 2013 the annual global market for navigation satellite products and services was valued at €175 billion. It is expected to grow over the next years to an estimated €237 billion in 2020.

What is GALILEO? What does it consist of?

Galileo is the programme of the European Union to develop a global navigation satellite system (GNSS) under civilian control. Galileo will allow users worldwide to know their exact position in time and space with great precision and reliability.

Once complete, the Galileo system will consist of an array of 30 satellites and the necessary ground infrastructure to control the satellites and enable the provision of positioning, navigation and timing services.


EGNOS, the European Geostationary Navigation Overlay Service, is Europe's first venture into satellite navigation. It is the EU's Satellite-Based Augmentation System, and is used to improve the accuracy of and provide information on the reliability of the GPS signal. (...)
