Galileo is the European Union's Global Navigation Satellite System (GNSS), managed by the European Union Agency for the Space Programme (EUSPA) with design and development by the European Space Agency (ESA). It provides highly accurate, guaranteed global positioning services under civilian control with improved positioning and timing information. Galileo offers various services, including an Open Service (OS) for mass-market use, a Search and Rescue (SAR) function, a High Accuracy Service (HAS), and a Public Regulated Service (PRS) for authorized users.
