GPS is short for Global Positioning System, a satellite-guided system of electronically determining the position and other variables that specify the movement of an object like a ship or a craft. GPS navigation is used for a number of both academic and daily life purposes. That is why the progress in enhancing the technology of GPS navigation has become quite rapid over the last two decades.

Now, GPS navigation is used widely in developed countries in devices like pocket computers, autos, and even cell phones. Many people find GPS navigation a useful guide in locating and specifying the movement of their personal cars along roads and streets.

Jeep has equipped the RT-300 with a paltry 3.5-incher. I found the choice of this 4:3, 320-by-240-pixel screen surprising—especially considering RT-300’s relatively high price ($249.99 direct). The one feature that might go a little way toward justifying the price is the RT-300’s nubby, soft, rubber protective sleeve. The unit has a tire-tread-like, ruggedized-ish styling.

RT-300 would probably absorb the shock of a fall better than a GPS without a rubber case, it lacks a waterproofing rating, for one thing, and that’s a feature I think off-road types would surely want. Would-be Jeep adventurers will also be disappointed by the lack of any off-road modes.

There’s been a lot of random misinformation about the iPhone 3G floating around out there, like David Pogue’s baffling comment that the device’s GPS antenna is “too small” to support turn-by-turn directions, and Apple’s iPod and iPhone marketing head Greg Joswiak recently sat down with AppScout to clear up some of the confusion.

Greg says that Apple has an internal priority list of features for the iPhone, and that the company went as far down the list with the 3G as it could — and that copy / paste support simply didn’t make the cut. Similarly, there are no technical issues preventing turn-by-turn directions, just other “complicated issues” (read: legal agreements) that need to be sorted out, and Josiwak expects developers to “amaze us.” as things “evolve.” Hopefully that means that nav app TomTom’s got in the labs will evolve its way into the wild sometime soon. Finally, Joswiak said that he’s not aware of any technical reasons an office suite isn’t already in the App Store, but that the lack of a cross-application file structure could impede development. Yeah, and maybe the lack of copy / paste, you think?

Russia’s bid to create a rival to the U.S. Global Positioning System, or GPS, has been delayed by equipment flaws and other technical problems, a senior Cabinet official said Wednesday.

First Deputy Prime Minister Sergei Ivanov acknowledged that Russia’s Global Navigation Satellite System, or GLONASS, failed to become fully operational at the year’s start as the government had planned.

Time to pimp your ride as mobile manufacturer giant Nokia has launched Nokia 500 Auto Navigation, its first handsfree personal navigation device. This further supports the forecast we’ve covered last May that personal navigation is the next the big thing in the mobile industry.

“The Nokia 500 Auto Navigation is an expansion of our extensive enhancements portfolio. Our solutions are tightly integrated with our mobile devices, allowing users to enjoy quality handsfree communication with their phonebook, music and competitive navigation,” said Nokia Automotive director Marcus Stahl, in a

A more exciting part of this whole personal navigation domination is that established GPS companies like TomTom and Garmin are currently developing mobile phones with GPS devices.
