Second European Positioning Satellite Launched

Galileo, which should be operational by 2013, will be both an alternative and a complement to the U.S. Global Positioning System (GPS) and the Russian GLONASS.

There are some articles which call Galileo a competitor to GPS, which really isn’t the case; this article does a better job. I expect a PND purchased a few years from now, once there are many Galileo and GLONASS satellites in operation, will be configured to accept and process data from all of them.
