Satellites operated in the United States and Europe will ping the same
following an agreement on a "common civil signal" design for the GPS
and Galileo satellite projects.
Discussions among representatives from the United States and the
European Union at a joint technical working group mean the satellite
navigation cooperation between their respective satellite navigation
systems. The signals sent out from the satellites had be optimised to
overcome "compatibility, interoperability and security issues"
according to this report.
"We are pleased by the adoption of this key improvement
to the common civil signal design," said U.S. State Department
Principal Deputy Assistant Secretary RenoHarnish
in a joint statement. "The U.S.-EU collaboration that produced this
innovation and led to its joint adoption reflects the strong working
relationships that we have developed on GPS and Galileo."
The two new satellite systems, the U.S. Navstar
GPS, which is already operational and the European Union's Galileo
which is in its initial deployment phase will beep along the same lines
making it easier for userson the ground to get a fix. The cooperation looks likely to also lead to future enhancements.
The GPS L1C signal and Galileo L1F signal provide greater positional precision,
better reception and greater coverage from any GPS or Galileo
satellite as the result of a similar agreement made in a 2004 which ensured compatibility and
interoperability at the user level.
