U.S. GPS Upgrade

The White House annouced today multiple upgrades to the U.S. GPS system.

From RCRNews:

"The new signal-known as 'L2C-was specifically designed with commercial needs in mind," said Deputy Commerce Secretary David Sampson in remarks prepared for delivery at a U.S. Chamber of Commerce press event this morning. "For example, it is transmitted with a higher effective power, so GPS receivers work better in urban areas and indoors. And it requires less energy to receive the signal, an important feature for battery-powered devices such as mobile phones."
