Galileo's fifth satellite (and first fully operational capability, or FOC, spacecraft) — recently salvaged from an incorrect orbit — has been combined with three predecessors to provide its very first position fix.
Test receivers at the European Space Agency (ESA) ESTEC technical center in Noordwijk, the Netherlands, and at the Galileo In-Orbit Test station at Redu, Belgium, received the signals at 12:48 GMT on December 9 from a quartet of Galileo satellites and fixed their horizontal positions to better than two meters.

A rule largely aimed at opening trade in telecommunication services will require Russia and other international providers of GNSS services to apply for authorization before their navigation signals can be legally used in the United States, a Federal Communications Commission (FCC) official has told GPS experts on the Space-based Positioning, Navigation, and Timing (PNT) Advisory Board.

Europe's fifth Galileo satellite, one of two delivered into a wrong orbit by a Russian Soyuz-Fregat launcher in August, transmitted its first navigation signal in space on Saturday (November 29, 2014) after reaching its new target orbit.
According to the European Space Agency (ESA), a detailed test campaign is under way now the satellite has reached a more suitable orbit for navigation purposes.

Every so often, anthropologists — and maybe a few mathematicians — have a field day puzzling over the origins of our positional base-10 numeral system.
Oh, not the historical origins themselves, the Hindu-Arabic innovations beginning in the 5th and 6th centuries. That’s all pretty much agreed.
No, I’m referring to the possible physiological inspirations, the readily visible digits at the ends of our limbs: 10 fingers, 10 toes.
Coincidence? Does nature have coincidents, or does it abhor them like vacuums — o horror vacui?

The European Space Agency (ESA) has announced completion of tests that indicate the readiness of the European component of a modernized, GNSS satellite–aided search and rescue service known as Cospas-Sarsat.
ESA has completed construction and testing of a trio of located on three islands at the far corners of the continent, ready to pick up distress calls via satellite from across Europe and its surrounding waters.
