Navigation beacons must be as visible as possible. So 20th century radio navigation towers guiding aircraft stood hundreds of metres tall, while the lighthouses guarding mariners of treacherous waters reach dozens of metres in height or cling to high ground. In essence navigation satellites are the same, except they are built on the ultimate high ground of space, making them visible from anywhere on Earth.

Goals of UIC participation in GALILEO project:

The Galileo Railway Applications Expert Group’s main activity is to follow up on matters relating to the certification and validation of Galileo for railway applications in the safety and non-safety area and to act in accordance with the mandate given by the UIC Executive Board to represent the railway viewpoint in contacts with EU projects and with the Galileo Joint Undertaking during the development stage of the Galileo Project which is due to enter operational service during the period 2008-2010.
