Deep in an underground bunker near the German-Czech border, through a 65-foot tunnel and locked behind five cold storage doors, German scientists are building a laser so advanced, so precise, that there isn’t another laser in the world that can challenge it. But despite the sinister-sounding backdrop, there’s nothing nefarious going on here. Researchers there have built the world’s most stable ring laser, and they’re using it to make unprecedentedly accurate measurements of the Earth’s rotation.
GPS is currently accurate to something like 9 feet. An Australian company says its new geolocation technology could shave that down to a few centimeters, if its hardware is rolled out across the world. The company, Locata, envisions a constellation of local “satellites”--known as “LocataLites”--installed in known locations across an area that allow devices to get a super-accurate fix on their locations.
The rise of readily available GPS-enabled devices was supposed to make losing one’s way a relic of a bygone era. But while GPS has undoubtedly changed the way we get around, it’s still imperfect – anywhere the satellite signal can’t reach might as well not be on the digital map because we can’t locate ourselves there. But researchers at NC State and Carnegie Mellon Universities may just have a solution. All they need to do is put radar in your shoe.
Sometimes, you want Big Brother to be watching. In that spirit, South Korean officials are turning to GPS technology to keep their kids safe from criminals, AFP reports.
Starting in October, about 1,200 elementary school children in Anyang City, south of Seoul, will receive matchbox-sized GPS-embedded beepers. The devices can notify authorities of the kids' location and activate surveillance cameras.
GPS may now reside in everything from our cars to our smart phones, but it once all began as a military application. So it's perhaps ironic, if not entirely shocking, that the head of the U.S. Air Force said today that the military needs to wean itself off dependence on a GPS network vulnerable to jamming and satellite-killing vehicles. DOD Buzz reports that officials have confirmed that GPS has been "jammed or interfered with recently."
GPS is indespensable, but reception is spotty indoors and in urban areas. A new system that uses digital television signals should clear the way for anytime, anywhere positioning

Today’s Global Positioning System is great for tracking tanks in the desert, but turn on your Garmin in New York City or inside virtually any building, and you’ll be staring at satellite static—GPS doesn’t perform well indoors or in urban canyons. Now a new technology is poised to pick up where GPS satellite signals cut out.
Developed by Rosum Corporation in Redwood City, California, TV-GPS, as the system is known, triangulates positions using television signals that are 2,000 times as strong as GPS satellite transmissions.
Technology may be ushering in a golden age of stalking, in which predators use GPS, cellphones and other devices to track and terrorize.

They fell for each other in grade school, in the sweetest of ways. In fifth-grade music class, she played saxophone; he played the snare drum. In high school biology, she held the frog while he wielded the scalpel. It was the sort of love story immortalized endlessly in romance novels and Top 40 long-distance dedications. “I thought when I married him it really would be ’till death do us part,’ ” she says now, still surprised that the marriage ended after 19 years. Ultimately, the romance had sputtered to a close, as so many love stories do.
