This second signal is designed to withstand localized jamming and will be used by police and military services in Europe.

The first Galileo satellite is scheduled to launch late in 2004, Clocks on board the {{U}}(63) {{/U}} Will be synchronized through 20 ground sensors stations, two command centers and 15 uplink stations.
Receivers on the ground will use time signals from the satellites to precisely calculate their {{U}}(64) {{/U}}. A "search and rescue" function will also {{U}}(65) {{/U}} distress signals be relayed through the constellation of satellites.
