Galileo on Its Own

TABLE 1: Deployment Status Note: Two types of clocks on board: PHM = Passive Hydrogen Maser, RAFS = Rubidium Atomic Frequency Standard

Europe’s new age of satellite navigation has passed a historic milestone — the very first determina-tion of a ground location using the four Galileo satellites currently in orbit together with their ground facilities.

This fundamental step confirms the Galileo system works as planned.

ESA Achieves First Galileo-Only 3D Position Fix

Measurements of individual Galileo horizontal position fixes performed for the first time using the four Galileo satellites in orbit plus the worldwide ground system between 1000 and 11:00 CET on Tuesday 12 March 2013, showing an overall horizontal accuracy over ESTEC in Noordwijk, the Netherlands, of 6.3 meters. ESA figure

The European Space Agency (ESA) has announced a key milestone today (March 12, 2013) in the development of Europe’s GNSS program: the first determination of a ground location using the four Galileo satellites currently in orbit together with the system’s ground infrastructure.

This fundamental step confirms the Galileo system works as planned, according to ESA scientists.
