As anyone who's tried to use GPS indoors can tell you, global positioning systems have their limitations. For them to work properly, you have to be outdoors and you need a clear view of the sky. If you’re in the military, you also have to be sure that the enemy isn't jamming the satellite signal. For this reason, the US Air Force has awarded Canberra-based firm Locata a “sole source” contract to install a ground-based version of GPS over 2,500 square miles (6,475 sq/km) of the White Sands Missile Range in New Mexico as part of a program to develop a practical supplement to GPS.

Researchers at the Korean Advanced Institute of Science and Technology (KAIST) have developed a new indoor positioning system that makes it possible to build a Wi-Fi radio map that does not require GPS signals. It's claimed to be an improvement on Wi-Fi Positioning Systems, that rely on both GPS and Wi-Fi signals. Read More
One of the big sports-based breakthroughs of 2012 was the integration of GPS navigation into sports watches. Watches like the Garmin Fenix and Suunto Ambit offer users the ability to create tracks and navigate routes from the wrist. We're barely into 2013, and the GPS sports watch has made another big step: color mapping. Read More
Given that rogue nuclear tests are always conducted underground, the search for them has focused on efforts to refine the identification of characteristic seismic signatures. Now, researchers at Ohio State University (OSU) have discovered new detection methods in unlikely places – the rejected noise in GPS measurements and radio astronomy. Read More
GPS tracking is great for athletes and fitness freaks, but not everyone wants to be weighed down by a big, expensive watch. That seems to be the thinking behind the new GPS Track Pod from Suunto. The device strips GPS tracking down to its most basic, compact form, providing performance data without the price or complications of a fitness watch or gadget. Read More
A few months after launch, the Suunto Ambit GPS watch found itself in a predicament with some hard-hitting competition from the lower-priced Garmin Fenix. Not surprisingly, Suunto has been busy updating the Ambit ever since. Its official 2.0 update went live earlier this week, and brings the potential for a variety of new functions by way of apps. Your other portable electronics have apps, why not your sports watch? Read More
An Afghan designer has come up with a novel tumbleweed-esque device to find and detonate mines, a device that has evolved from the wind-powered toys he made as a child. Massoud Hassani's Mine Kafon is made mainly from bamboo and biodegradable plastics, but the simple addition of a GPS chip means the wind-swept spheres can be monitored to reveal the location of mines.

For the past several ski seasons, Recon Instruments has been designing, tweaking and partnering with other companies on its GPS-based ski goggles, which provide real-time feedback about speed, distance, vertical and other key indicators. The company has now officially re-purposed its technology for skydiving, BASE jumping and wingsuit flying. Read More
It was not long ago that the internet was going crazy over Google's Project Glass, and now Google has our attention again with the patent of a "smart watch." This watch appears to use technology similar to the glasses, but with a flip-up touchscreen instead of lenses. Read More
