TWINS!
Please.
Please. Please. Please.
Can we please talk about something besides LightSquared?
Not yet? You mean, they are still here?

[Updated October 3] All five of the world’s major satellite navigation systems are poised to offer new capability — if the money comes through — program representatives told attendees at the recent Institute of Navigation’s GNSS 2011 conference in Portland.
The satellite navigation systems in China, Japan, and the United States have each recently had new satellites added, while those in Russia and Europe are poised for new launches. Budgets are in flux for most systems, however, so it remains to be seen how the systems will advance over the next year.
