It's been awhile since we heard much about Lockheed Martin's GPS III satellite family beyond mention of an early prototype. The next-gen positioning system just took a big step forward with word that the company has successfully powered up the first production craft of the bunch, Space Vehicle One. Flicking the switch clears it for testing and keeps the GPS III program's 2014 launch window within view. More importantly, the activation takes us one step closer to improved GPS accuracy for civilians and soldiers alike.
