US/EU final agreement on GPS-Galileo civil signal.

The US and the EU have announced their agreement to jointly adopt and provide an improved design for their respective Global Navigation Satellite System (GNSS) signals. These signals will be implemented on the Galileo Open Service and the GPS IIIA new civil signal. Building on the cooperative agreement on GPS and Galileo signed between the two parties in June 2004, a joint compatibility and interoperability working group has overcome technical challenges to design interoperable optimized civil signals that will also protect common security interests. The resulting GPS L1C signal and Galileo L1F signal have been optimized to use a multiplexed binary offset carrier (MBOC) waveform. Future receivers using the MBOC signal should be able to track the GPS and/or Galileo signals with higher accuracy in challenging environments that include multipath, noise, and interference.
