GPS is everywhere; does everything

First GPS in China will somehow enable safe food for the upcoming Olympics. From the AP:

China said Monday it will use global positioning satellites to ensure food safety at the Beijing Olympics as it steps up efforts to blacklist manufacturers who violate safety regulations.

Wang Wei, an executive vice president of the Beijing Olympic Committee, said the high-tech system will monitor food production, processing factories and food hygiene during the games to make sure healthy food is delivered to the 10,500 athletes residing in the Olympic Village.

Those sounds like huge claims for the system, as I understand it. The claims of GPS in medicine, however, seem to be correct. From the Chicago Tribune:
The technology that enables this exceptionally accurate surgery uses three tiny "satellites," [Dr. Kevin] Luke explained.

The devices, which transmit wireless signals to a computer, are inserted into the surgical incision and triangulate the exact position of surgical instruments and the anatomy of the patient.
