Global Positioning Systems work famously here on the home planet because we control all of the moving parts; put some satellites in the sky, equip a device with the proper hardware to communicate with them, and you can locate yourself just about anywhere. But how would we locate ourselves in deep space? For that kind of spatial location, a team of Italian researchers have devised a way to calculate one’s position in space using pulsars as interstellar navigation beacons.
Five South African rhinos have been outfitted with an extra layer of defense against poachers, thanks to a GPS chip implanted in their horns. The chips are inserted into a small hole drilled into the dead portion of the horn. Currently being tested in Mafikeng Game Reserve, the devices are connected to a cell phone system that allows game wardens to monitor the animals constantly and remotely.
Bike-sharing programs across the U.S. are getting an upgrade.

Urban bike-sharing in U.S. cities. Already booming in Europe, these membership-based services start around $5 a month, saving commuters at least $5,000 a year on average over owning a car.
Smartphone apps allow riders to find bikes quickly, and inexpensive radio-frequency-identification or GPS chips help bike companies track the riders remotely. The chips are linked to riders’ credit-card information, so they won’t be tempted to steal the bike.
Israeli researchers have created the tiniest-ever optical gyroscopes, as small as a grain of sand, but still maintaining the keen accuracy of their counterparts hundreds of times larger. Optical gyroscopes are generally used for navigation in airplanes, ships and satellites, in which they track movement without reference to external navigation points, by measuring the vehicle's rotation rate and linear acceleration. This is called inertial navigation.
Our GPS-wielding smartphones have made it somewhat difficult to get lost, say, on the way to the museum. But if you’re waiting for the day your phone will also help you navigate to a specific painting once you’re inside, you might be waiting a while. The technology exists, but no single version is perfect. And a lack of a standout Indoor Positioning Systems (IPS) technology means there is no broad agreement on which technology should become the new standard.
Americans have a prison problem -- namely, we've got a whole lot of people in prisons and that's a huge drain not only on hard money in our public coffers, but on man-hours lost by both the inmates and the people who spend their productive hours keeping an eye on them. But Graeme Wood, writing in The Atlantic, describes a new prison paradigm that would take the economic – and, for the inmates, psychological – duress out of our penal system: let most of the inmates go free.
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.
A team of NASA researchers has successfully completed the first demonstration of a prototype tsunami prediction system. Using global and regional real-time data from hundreds of GPS sites, the new system can quickly assess large earthquakes and accurately predict the size of resulting tsunamis.
The new system, developed by Y. Tony Song and his colleagues at NASA's Jet Propulsion Laboratory, uses GPS data from NASA's Global Differential GPS (GDGPS) and information about continental slope (where the ocean floor descends from the edge of the continent to the ocean bottom) to estimate the energy transferred to the ocean by an undersea earthquake.
Today's cars may seem too sophisticated for tinkering, but the DIY auto movement is thriving, yielding designs and innovations too radical for mass production. Here are four awesome examples of modern garage-guy ingenuity.
Evasive speed demons may have a harder time avoiding a GPS-enabled speed camera which can capture license plate numbers under any weather condition, 24 hours a day. The new speed cameras in the UK use GPS satellites to help measure cars' average driving speeds over long distances, The Telegraph reports.
