Lockheed Martin powers up its first GPS III satellite, stays on track for 2014
It's been awhile since we heard much about Lockheed Martin's GPS III satellite family beyond mention of an early prototype. The next-gen positioning system just took a big step forward with word that the company has successfully powered up the first production craft of the bunch, Space Vehicle One. Flicking the switch clears it for testing and keeps the GPS III program's 2014 launch window within view. More importantly, the activation takes us one step closer to improved GPS accuracy for civilians and soldiers alike.

IndoorAtlas uses disturbances in the (geomagnetic) force to map interiors, plot a path to aisle 3 (video)
Interior navigation is only just coming into its own, but IndoorAtlas has developed a technology that could make it just as natural as breathing -- or at least, firing up a smartphone's mapping software. Developed by a team at Finland's University of Oulu, the method relies on identifying the unique geomagnetic field of every location on Earth to get positioning through a mobile device. It's not just accurate, to less than 6.6 feet, but can work without help from wireless signals and at depths that would scare off mere mortal technologies: IndoorAtlas has already conducted tests in a mine 4,593 feet deep. Geomagnetic location-finding is already available through an Android API, with hints of more platforms in the future. It will still need some tender loving care from app developers before we're using our smartphones to navigate through the grocery store as well as IndoorAtlas does in a video after the break.

There's no shortage of navigation outdoors, and even a little bit of help indoors, but there's been precious little aid for the blind indoors -- leaving them little choice but to move cautiously or get outside help. Fujitsu and Japan's NICT have crafted a system that gives the sightless a greater level of autonomy inside through ultrawideband-based impulse radio. A grid of UWB radios positioned around a room gauge the distances between each other and transmit the data to a PC, which then talks to the traveler's Android phone. The device then gives spoken directions based on a 12-o'clock system and far subtler distances than GPS can manage: the positioning is accurate to within a foot. While the indoors navigation is only just getting a demo this week, it's already being refined to detect objects in the room as well as to help even the fully sighted. If Fujitsu and NICT have their way, buildings ranging from hospitals to malls will have their own turn-by-turn navigation. For some, the freedom of movement could be a life-changer.

Just in case GPS and GLONASS didn't make for enough of an acronym soup, BAE Systems wants to add one more to the navigation broth. NAVSOP (Navigation via Signals of Opportunity) uses some of the basic concepts we know from cell tower triangulation and WiFi location-finding to lock down a position, but goes much further to geolocate from nearly anything that pushes out a signal, such as nearby radios and TVs. It doesn't even need to know what kind of signal it's looking at, and it can get its position in places there's no GPS to work from, whether it's in an urban canyon or the natural kind. BAE is most excited about the prospects of ending GPS jamming against soldiers and UAVs, once and for all: not only is the new technology mostly impervious to attempts to block its signal, it can use the jamming attempt itself to get the position fix. Thankfully, the company's roots in defense aren't precluding use for civilians, so there's a chance that future smartphones might never have to use guesswork to get their bearings -- provided that governments around the world sign off on the idea, that is.
