...Intelligence and Information Warfare division is currently hawking a system called Cell Hound that detects all active cell phones within a prison facility and then displays the location on a computer monitor. The monitoring device can also be used to gather intelligence on other illegal activity among inmates. Last month, a Maryland investigation that included wiretaps on prison cell phones resulted in drug and weapons charges for two dozen people, including four state prison officers...
Hikers do it. Ambulance drivers do it. Even fighter pilots do it. Around the world, millions of people use the global positioning system, or GPS, to know where they are and where they're headed. The satellite-based navigation system has become an indispensable tool for everyone from cell-phone manufacturers to oil drillers, which explains why a government report on GPS released this month prompted a tide of concern. The Government Accountability Office warned of "significant challenges" to maintaining the system at full strength beginning as soon as next year, due to technical problems and delays...
...launched in 1957. U.S. scientists learned they could track the satellite's orbit by listening to changes in its radio frequency, relying on the same principle that explains why the pitch of a car's horn seem to change as the car speeds by. The Navy's TRANSIT navigation system was developed in the 1960s, relying on six satellites and designed originally for use by submarines. More than 10 satellites were eventually launched, though ground units had to wait up to several hours to pick up a signal. Meanwhile, engineers Ivan Getting and Bradford Parkinson began leading a Defense Department...
...plays a major role in American military combat, guiding missiles and bombs to their destinations in Iraq, Afghanistan and elsewhere. President Reagan opened the fledgling navigational system to nonmilitary uses in 1983 after Soviet fighter jets shot down Korean Air flight 007, a passenger jet that had accidentally strayed into Soviet airspace, killing all 269 on board...
...report does not predict that the GPS system will fail outright; it offers a more mild (and vague) warning, suggesting only that a delay in replacing satellites may impede "the level of GPS service that the U.S. government commits to." But given the world's growing dependence on the space-age compasses, the military scrambled to quell any concerns. "The issue is under control. We are working hard to get out the word," Air Force Col. Dave Buckman wrote to worried questioners on a military Twitter account May 20. "GPS isn't falling...
