This month there is good news — great news, actually — where GPS and PNT (Position, Navigation and Timing) systems are concerned. On October 22, a Russian Soyuz rocket placed in orbit the first two validation satellites, built by EADS Astrium Germany, in the Galileo PNT constellation after making its maiden launch from Kourou. Don’t confuse these recent satellites with the earlier experimental satellites, GIOVE-A launched in 2005 followed by GIOVE-B launched in 2008. These initial satellites served to preserve the Galileo ITU frequency filings and test the first-ever space borne Hydrogen Maser atomic clock, which by all accounts is proving to be extremely accurate. read more
