Hasta La Gadget!

Though plenty of firms (including some big ones) have been trying to commercialize consumer-facing indoor positioning technologies for years, none have succeeded on a wide scale — which certainly seems to leave the door wide open for a system that actually works to be wildly successful, doesn’t it? Rosum has been toying with the idea of using plain old TV signals to accurately locate people and objects within GPS-hating structures for years, and with today’s launch of its so-called Alloy system with partner Siano, the company could be closer to wide-scale deployment. Basically, Alloy combines AGPS (for maximum precision outdoors and in marginal areas) with support for a variety of types of TV signals to enhance coverage and provide <150 meter accuracy even in the deepest, darkest, dankest corners of your home where traditional GPS would never dream of going. What’s more, Rosum touts that TV positioning is several orders of magnitude more power-efficient than AGPS, music to the ears of anyone who’s struggling to get a full day’s battery out of their phone. They’re sampling chipsets beginning this month, but don’t expect it in handsets right away — Rosum’s primary target appears to be femtocell makers. The devices traditionally require GPS reception, requiring unsightly remote GPS antennas if you’re not interested in balancing the cell on a window sill, so a technology like this should let you properly bury that network extender behind a bookshelf where it belongs. Follow the break for Rosum’s press release.

Uh, folks — we’ve an identity crisis on our hands. Is this a MID with a penchant for navigating? Is this a PMP with pre-loaded maps? Is it an ultra-sleek navigator that just so happens to play music? There’s a fair chance the world will never know, but we’ll soon be stopping by Mio‘s booth at CeBIT in order to get a view of things ourselves. At any rate, the Moov V780 is undoubtedly one of the most appealing things to come from the outfit in quite some time, offering up 720p multimedia playback, an HDMI output, digital TV support, a 7-inch (800 x 480 resolution) display, 600MHz CPU, 512MB of memory, 4GB of onboard flash and a pretty tremendous list of supported file formats. Sadly, it’s humming along on Windows CE (rather than, say, Android), but at least it ships with WiFi and optional WiMAX. There’s no mention of a price or release date, but we’ll be on the hunt for those tidbits as soon as the show floor opens up.

Ford’s been keeping itself busy on the navigation front, and while you may have noticed that 2010 just began a few weeks ago (on the Gregorian calendar, anyway), 2011 model year vehicles are already on the minds of those in Dearborn. 2011 models with voice-activated navigation systems will be getting an update that brings along HOV logic, helping users who travel with a buddy to get from point A to point B more hastily if carpool lanes are nearby. Of course, only 2,500 miles of those blanket America, so a few other updates might be intriguing to those of you who are sane enough to live outside of the rat race. Branded POI icons, higher density street labeling and HD Radio will come standard on voice-controlled NAV systems, and potentially most interesting is the notion that “integration with SYNC Traffic, Directions and Information (TDI) app — enabling new features like the ability to download destinations sent from a home or work computer from Mapquest” — will hit later on in the year. Full release is after the break.

Editor’s note: This story has been updated. The LoJack car-security system is based on radio frequency technology, not GPS.

Every time tech is used to fight crime, the bad guys just get better gear. The only crime-fighter who manages to always have the better gadget is Batman. Now car thieves are using GPS jammers to blot out the satellite signals that some antitheft services use to locate stolen automobiles.

It’s not hard to do, either. A quick Google Shopping search for GPS blockers shows models on sale for under $30. They don’t even need to be powerful. In order to swamp the incoming satellite signals, a jammer only needs to put out two watts of power. Speaking at a symposium, Bob Cockshott of “cybersecurity” company Digital Systems KTN said that “the strength of a GPS signal is about as strong as viewing a 25-watt light bulb from a satellite 10,000 miles away.” Small wonder that sat-nav devices take so long to acquire a lock.

It’s not just criminals who are using this tech, either. Employees whose cars are tracked by their companies use them to go off the clock, and according to The Guardian, German truck drivers use them to “to evade GPS-based road charging.”

But knocking off gas-guzzling cars and sticking it to the man are just the annoying part of the potential for GPS jammers. A 20-watt unit would be enough to cover a commercial airport, with rather scary results.

There is also the possibility of feeding false signals to a GPS unit, which would be harder for an operator to spot than straight-up jamming. If you start doing that to boats driven by sailors with no sextant experience, you get havoc.

Still, something good could come of this. It’s possible that people reading the story could become less trusting of their in-car sat-nav units and actually look through the windshield once in a while. This would avoid the estimated 300,000 crashes caused in Britain every year by GPS-following fools.
