With GPS, getting around gets easier
In recent years, Global Positioning System navigation, commonly known as GPS, has rapidly migrated from oceangoing vessels and adventurers' backpacks to the dashboards of luxury sedans.
In yet another leap into the mainstream, GPS technology, cheaper yet more sophisticated than ever, is increasingly finding its way into the palms of everyday users.
In an array of devices, many new and some newly enhanced, the use of orbiting satellites to orient and guide travelers has never been simpler, more accurate or, well, cooler.
Taking advantage of faster, smaller processors; higher-resolution liquid crystal display, or LCD, color screens; and more efficient antennas, digital storage and software, GPS devices are becoming an ever more compact source of useful maps with walking and driving cues.
