Geodetic Research Laboratory, Department of Geodesy and Geomatics Engineering GEOIDE Project 31 Quebec Workshop, October 2006, Quebec Farret and Santos, WHAT IS GALILEO? Galileo will be an independent, global, European-controlled satellite-based navigation system. - It consists of a Space Segment with a total of 30 satellites ( in-orbit spares) in Medium-Earth Orbit (MEO) and a Ground Segment providing system and satellite monitoring and control, as well as an Integrity function to broadcast real-time warnings of satellite or system malfunctions.

Geodetic Research Laboratory, Department of Geodesy and Geomatics Engineering GEOIDE Project 31 Quebec Workshop, October 2006, Quebec Farret and Santos, Galileo will provide navigation services of the following types:  Open Service providing global positioning and timing services, free of charge;  Safety-of-Life Service providing integrity services with a defined time-to-alarm limit;  Commercial Service providing data dissemination services;  Public Regulated Service providing global positioning and timing services.
