Space signal demonstrates Galileo interoperability with GPS

France: European Space Agency’s (ESA) first two Galileo navigation satellites in space have achieved their latest milestone. The satellites have transmitted dummy signals in a modulation scheme designed to allow full interoperability with the US GPS.
 
“This is an advanced modulation technique that offers robust protection against signal interference and the misleading signal reflections known as ‘multipath’,” said Marco Falcone, Head of Galileo System Services.

“Significantly, this is also the European version of the Multiplexed Binary Offset Code signal standard agreed with the United States for the interoperability of Galileo and GPS.

“So this transmission helps demonstrate how the two systems will work together in future with no risk of signal interference.”  
 
The first two Galileo satellites were launched from Europe’s Spaceport in French Guiana into medium orbits on 21 October 2011, and since then have been progressively put through their paces in a series of tests.
