China successfully launched another two Compass/BeiDou satellites into space at 3:10 a.m. Beijing time on Wednesday (September 19, 2012), according to the Chinese state news agency Xinhua.
They were the 14th and 15th satellites for the nation’s GNSS system, and presumably the fourth and fifth middle-Earth-orbiting (MEO) satellites in the constellation. The satellites, launched from the Xichang Satellite Launch Center in southwest China's Sichuan Province, were boosted by a Long March-3B carrier rocket.

A new U.S. appellate court decision could bring the issue of warrantless tracking of suspects using GPS and other positioning data derived from mobile phones back before the Supreme Court.
And if the case — United States of America v.
