Global Positioning System Satellites

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.

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."
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.

After starting out by helping pilots get around, navigational device maker Garmin Ltd. is now more likely to aid a motorist in finding the quickest interstate or the nearest pizza parlor. But as drivers have snapped up millions of the satellite-reading devices for their cars, the surge in interest has attracted new and bigger players into what had been a rather isolated market. Now Garmin could need one of its GPS units just to keep from getting lost.

Trimble Navigation Ltd. said it will partner with Germany's Siemens to boost sales of global positioning system devices, which can be used to track locations worldwide. Sunnyvale-based Trimble said it will work with the semiconductor unit of Siemens to design and manufacture new versions of GPS systems. It did not disclose the terms of the alliance.

The TomTom Go 700 sounds like a dream gadget for Southern California drivers: a GPS navigation unit for the car that not only pinpoints exact position and maps out directions, but also provides real-time traffic information for the route. It can even, at the push of a touch screen, almost instantly remap a route to avoid traffic snarls. It's an undeniably innovative use of the satellite-based global positioning system in conjunction with traffic data from the Internet.

Sunnyvale-based Trimble Navigation Ltd. said it will resume shipments of global positioning system units to American Mobile Satellite Corp., ending a dispute that included litigation. Trimble, which makes satellite-based navigation and communication systems, said it will begin shipping its Galaxy units in March. The Galaxy units are used to precisely determine location and facilitate data transmissions. Reston, Va.
