Galileo is a European global satellite navigation system created by the European Union. It has been operational since 2016 and is used beyond Europe: compatible devices worldwide can receive Galileo signals for positioning, navigation, and precise timing.
For the average user, the main difference with Galileo is that it does not require separate installation or downloading. The system operates via the device's dedicated navigation chip. Modern smartphones typically use multiple satellite systems simultaneously—such as GPS, Galileo, and other GNSS. The phone receives signals from satellites, determines the distance to them, and calculates its own coordinates. Processing data from multiple systems helps improve positioning accuracy and reliability.
Where is Galileo installed?
Galileo is supported by smartphones, car navigation systems, smartwatches, bike computers, professional surveying equipment, and other devices equipped with a compatible GNSS receiver. In vehicles, the system is also used for navigation and location-based services. Since 2018, Galileo has been supported by all new vehicle types sold in Europe that are subject to eCall emergency call system requirements.
For the average smartphone owner, Galileo is virtually invisible: the user opens maps, plans a route, or calls a taxi, while the device automatically utilizes available satellite signals. In cities with tall buildings, additional data from Galileo can help improve location accuracy.
Who is the system for?
Galileo is designed for both everyday users and professional applications. It is used in road transport, aviation, agriculture, the railway industry, maritime shipping, surveying, and unmanned systems. For example, a tractor can use satellite positioning to navigate a field with greater precision, while a car can use it for navigation and determining coordinates.
Galileo also features a dedicated High Accuracy Service (HAS) for tasks requiring greater precision. The European Commission indicates that horizontal positioning accuracy of approximately 20 cm is achievable when using compatible equipment and appropriate processing methods.
The system consists of satellites, ground infrastructure, and user receivers. Satellites transmit navigation signals, ground centers monitor system operations, and the user's device receives these signals and calculates coordinates. Galileo is compatible with other satellite systems, so a modern smartphone or vehicle typically does not rely on just a single satellite constellation.
For most people, Galileo has already become an invisible part of everyday navigation: it operates within smartphones, cars, or other compatible devices, helping to pinpoint the location of a person or vehicle more accurately.
