GPS Business News reports on an upgrade to SkyHook Wireless' mobile positioning engine, XPS 2.0. "The original XPS was switching between Wi-Fi and GPS; now XPS 2.0 combines raw Wi-Fi, GPS and cell tower readings to produce a single hybrid calculation. In difficult indoor and urban environments, XPS can, for example, leverage signals from just two GPS satellites to improve Wi-Fi location accuracy by 35%+, said Skyhook.
...
The addition of cell tower positioning also increases availability so that users at least get a fallback location regardless of environment."
SkyHook also seems to be licensing its technology to chipset manufacturers, as reported here "CSR offers a Wi-Fi chipset and a Bluetooth/FM/software GPS chipset as well as its own eGPS software that reads cell tower signal to augment the GPS positioning."
Indoors or out, I can determine my position and not miss a beat (but might miss a little accuracy...)

Location enhanced browsing on the phone

David Cizek writes " Locify (www.locify.com) offers location enhanced browsing on the mobile phone. It is free GPS application for J2ME phone.
As users browse usual web pages on the inbuilt xhtml browser, the GPS coordinates can be sent with each request to the webserver and they can get location relevant data (if the service offers them).
Developers can create location based services as easy as programming web pages.
Locify relies on developers — their goal is not to create our own services but give reason for developers to write them. Although Locify created a couple of sample services — like Twittering your location, Save My Position and Show Me on Map. The code is well documented so developers can learn and inspire.
Locify is free and open.
See and watch more on www.locify.com or read Locify blog."

GPS on the iPhone 2 comments
[+]
The Map Room blog brings us some detail information about the new built in iPhone 3G gps functionality. I believe they're calling it AGPS, but here is an excerpt from their blog : "iPhone 3G uses signals from GPS satellites, Wi-Fi hot spots, and cellular towers to get the most accurate location fast. If GPS is available, iPhone displays a blue GPS indicator. But if you’re inside — without a clear line of sight to a GPS satellite — iPhone finds you via Wi-Fi. If you’re not in range of a Wi-Fi hot spot, iPhone finds you using cellular towers. And the size of a location circle tells you how accurately iPhone is able to calculate that location: The smaller the circle, the more accurate the location."

NemeriX scores patent for single-chip GPS, GLONASS, Galileo receiver
by Donald Melanson, posted May 28th 2008 at 3:56PM
It looks like NemeriX is doing its part to bridge the GPS, GLONASS, Galileo divide, with it proudly announcing today that it's received a patent for a single-chip RF receiver technology that'll accommodate all three satellite navigation systems (China's Compass will apparently have to go it alone). Among other things, the single-chip solution will allow for manufacturers to reduce the size of their navigation devices by not having to include three parallel receivers, as well as allow them to market the same device to various markets around the world. Of course, there are scant few details about when we can actually expect to see the technology put to use, but NemeriX sees no shortage of potential applications, with it boasting that it'll provide customers with a "future-proof platform" that'll increase the availability and accuracy of "emerging location based services such as pedestrian navigation and mobile social-based networking.""

Industry: Bluetooth travel time estimation 1 comment

SEWilco writes "Tracking electronic serial numbers in Bluetooth transmissions could be used to estimate travel times, following tests by engineers with the Indiana Department of Transportation and Purdue University. Signals were detected from about one percent of cars, which is sufficient for frequently updating travel time information."
Cell Phones Tracking Nightlife Activity
[+]
Slashdot is currently discussing an article on Citysense, which is used to track users actions by their cell phones. Here is their summary : "A Columbia University computer science professor has co-founded a New York-based company named Sense Networks to sell tracking software to other companies. It is also distributing a free version of this software, named Citysense, which shows on your cell phone where the wild things are happening in your own town. Citysense 'uses advanced machine learning techniques to number crunch vast amounts of data emanating from thousands of cell-phones, GPS-equipped cabs and other data devices to paint live pictures of where people are gathering.' Citysense is available today in San Francisco, before being soon deployed in Chicago and five other U.S. cities."
