According to Reuters, the U.S. and the European Union are close to an agreement that would have their respective satellite navigation systems work together. Word has it that the agreement could be signed this week.
The benefits are big. Both the EU and U.S. satellites would use the same radio frequency. Although there will be GPS and Galileo receivers, they will be combined in systems eventually. In the meantime, receivers would be receiving data from twice as many satellites.
To date the U.S. has 30 satellites and plans to launch an updated GPS system by 2013, while the EU expects to reach 30 in space by 2010. Galileo is expected to be fully operational by 2012.
Stay tuned for the announcement.
