First Positioning Results Using Galileo Announced

July 17, 2012By

A team of Canadian and German researchers have obtained precise three-dimensional positions using measurements from the four prototype Galileo satellites now in orbit. The two In-Orbit Validation (IOV) satellites launched in October 2011 joined the two Galileo In-Orbit Validation Element (GIOVE) satellites launched in 2005 and 2008, forming a mini-constellation. For a few hours on certain days, signals from all... read more

The System: Galileo IOV Satellites Now in Orbit

November 1, 2011By

The first two satellites for Europe’s Galileo global navigation satellite system were lofted into orbit October 21 by the first Russian Soyuz vehicle ever launched from Europe’s Spaceport in French Guiana in a milestone mission, reports the European Space Agency (ESA). The launch occurred one day after initially scheduled to resolve a problem with the ground-support fueling system. The Soyuz... read more

GIOVE-B E1 CBOC Signal Quality Assessment
GIOVE-B has been in orbit for just over one year. How well is it performing? In particular, what can we say about one of GIOVE-B's pioneering features: its E1 CBOC signal? In this month's column, we take a detailed look at a particular monitoring and assessment program set up to examine the GIOVE-B signals and discuss some of its initial CBOC results. The successful operation of this program bodes well for its use in future validation campaigns. read more
