Golf is a game of rituals, and few are more sacred or idiosyncratic than the methods players use to line up a shot. Some toss blades of grass into the air to check the wind. Others focus on a twig or a leaf in front of the ball to align themselves with the flag. Then there are those who consult the computer screen in their cart for coordinates calculated by triangulating signals from global positioning satellites floating 11,000 miles above the earth's surface.

I am one of many American males too proud and stubborn to ask for driving directions. But I was forced to put my ego aside when faced with the prospect of losing something more important than my pride: the ability to enjoy an auto tour of Europe without wasting time getting lost or being frustrated deciphering maps in languages I did not understand. The source of my salvation was a global positioning satellite, or GPS, device, which made it difficult, though not impossible, to get lost.

When not being used to measure yardage to the green or to track philandering partners, the consumer GPS (global positioning system) may get its heaviest workout as conduit for the Tech Age scavenger hunts known as geocaching. For stick-in-the-muds still mired in the dark ages of the 20th century, GPS gizmos use satellite signals to determine a user's precise whereabouts within a range of several feet.
Several federal agencies issued a warning Thursday to hikers, boaters, drivers and others who use the global positioning system to beware of the possibility that their devices may malfunction Aug. 21-22 because of an unusual phenomenon known as "End of Week Rollover." The rollover problem stems from the original design of the GPS, which calculates the date by counting the number of weeks from Jan. 6, 1980. After the 1,024th week--about 20 years--the system resets back to zero.

President Bush has ordered plans for temporarily disabling the U.S. network of global positioning satellites during a national crisis to prevent terrorists from using the navigational technology, the White House said Wednesday. Any shutdown of the network inside the United States would come under only the most remarkable circumstances, said a Bush administration official who spoke to a small group of reporters at the White House on condition of anonymity.

The Boeing Co. said it has assembled a team of four leaders from the global information industry to compete for what ultimately would be a multibillion-dollar contract to overhaul the Global Positioning System for navigation and timing. Boeing's Government Information & Communications Systems unit in Anaheim and its partners have bid on the $16-million first phase of the project, a yearlong study to help define the next generation of GPS technology, called GPS III. The U.S.

Cyclists, runners, walkers, even swimmers and windsurfers, have now gone global. Using small, global-positioning devices, outdoor athletes are mapping their routes, tracking their distance, speed and elevation -- even creating their own virtual training partners, ones that beep instead of speaking when athletes are ahead of, or behind, their target goals. "If you're a gadget person," says Bruce Mosier, an avid runner and hiker from Santa Monica, "GPS is one of those things you absolutely need."

An automobile navigation system seems like the perfect high-tech gadget in car-dependent Los Angeles. It can identify where you are, give audible directions to destinations as you drive and even plan alternative routes in case of traffic jams. These units, which use global positioning system, or GPS, satellites to pinpoint locations on their screens, now come as standard equipment on some high-end cars and are available as built-in options on many others.
Earthquake experts Monday proposed establishment of a dense array of 250 Global Positioning System stations in urban areas of Southern California to allow more precise determinations of seismic strains accumulating in the region and improve long-range earthquake forecasting. Representatives of the Southern California Earthquake Center at USC, the U.S.
There is little but prairie surrounding the carefully guarded buildings. From the time authorized personnel slide their personalized badges through the card reader and punch in a four-digit access code, they have 15 seconds to pass through a door leading to the master control station. Down a long hallway, seven people in blue jumpsuits work at computer terminals.
