GPS Users Fear Getting Lost In Wireless Expansion

GPS devices have become ubiquitous: Millions of drivers rely on them for directions. The government hopes to construct a new air traffic control system based on GPS navigation rather than the use of radar. They've also become an important tool in agriculture. But a multibillion-dollar proposal to provide broadband Internet access using satellites and a network of 40,000 antennas could interfere with their devices. This could potentially make it harder for first responders to find emergencies, aviators to fly and drivers to navigate.
