The United States and the European Union have moved forward on satellite navigation cooperation after reaching agreement on a common civil signal design for their respective satellite navigation systems (GNSS). The U.S. Navstar GPS is the only fully operational GNSS, with the EU's Galileo project in the initial deployment phase.
The pact was reached following discussions among members of a joint technical working group.
"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 Reno Harnish in a joint statement with his European counterparts. "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 resulting GPS L1C signal and Galileo L1F signal were given the go-ahead after both were optimized to overcome compatibility, interoperability and security issues. The experts team also proposed incorporating the multiplexed binary offset carrier (MBOC) waveform on future receivers to enable these to get more accurate images and information from both GNSS amid challenging environments that include multipath, noise and interference.
The common signals will be implemented on the Galileo Open Service and the GPS IIIA new civil signal.
"Incorporating MBOC into both GPS and Galileo will enhance commercial opportunities for the development of new GNSS products and services," the EU said on its portal site Europa. "Manufacturers and product designers will have the benefit of adequate lead time to ensure products developed will meet the needs of users around the world."
Adds European Commission Director-General Matthias Ruete, "The international GNSS community, including the U.S., will have full and transparent access to information on how to access Galileo and GPS services," he said. "This should facilitate the rapid acceptance of Galileo in global markets side by side with GPS."
