Model of a Galileo satellite. This is a list of past and present satellites of the Galileo navigation system.The fully operational constellation will nominally consist of 30 satellites in Medium Earth Orbit, with 24 active and 6 spares equally divided into 3 orbital planes in a Walker 24/3/1 configuration.

Additionally, the Galileo component of the MEOSAR system is able to download information back to the distress radio-beacon by encoding "Return Link Service" messages into the Galileo navigation data stream. It can be used to activate an indicator on the beacon to confirm receipt of the distress message.
Galileo is a computer reservations system (CRS) owned by Travelport. As of 2000, it had a 26.4% share of worldwide CRS airline bookings. [ 1 ] In addition to airline reservations, the Galileo CRS is also used to book train travel, cruises , car rental, and hotel rooms.
Galileo's tidal theory entailed the actual, physical movement of the Earth; that is, if true, it would have provided the kind of proof that Foucault's pendulum apparently provided two centuries later. Without reference to Galileo's tidal theory, there would be no difference between the Copernican and Tychonic systems.
