America's GPS Falls Under the Rival EU and China Satellites' Shadow.

China, Russia, and the European Union have developed satellite networks that offer global positioning services, posing a challenge to the aging U.S. Global Positioning System (GPS).

Other countries' more advanced systems, such as China's Beidou system, could potentially give them influence over global commerce and pose security risks. The U.S. plans to continue using GPS's original radio frequency while adding new channels to avoid making dependent devices obsolete. [Extracted from the article]
