    It is not too accurate, about within 200' or so from my location shown on the satelite map...

    That, in itself, is evidence that it does not have GPS.

    Maybe

     

    Civilian GPS is accurate to +/- 30 meters, so a maximum inaccuracy of 60 meters (180ft approx) would be possible with GPS, "about 200'" out is possible with a GPS system.

    Naah.  It's better than that.

    SA (selective Availability) was turned off May 1, 2000.

    If civilian GPS was accurate to only 30+/- meters, there is no way it would be FAA approved.

    The only limitation is the quality/accuracy of the equipment.

    Most commercial, low end GPS receivers (such as hand helds and auto)  are accurate to ~3-10 meters.

    Higher end survey equipment and such can go down to a centimeter.

    President Bill Clinton ordering Selective Availability to be turned off at midnight May 1, 2000, improving the precision of civilian GPS from 100 meters (330 ft) to 20 meters (66 ft).

     

    Prior to that the accuracy was as I stated, thanks for the correction.

    You guys have no ideas what your talking about.  It has a gps chip.  Apple in thier wisdom  turns it off with no wifi connection.  Which is totally lame.

     

    WiFi models do have GPS. For some reason they turn it off when there is no wifi connection. I operate several boats and use iNavx, iRegatta and other apps with various iPads both 3G and WiFi only.  I use a Toughbook in adhoc network mode to create a wifi connection.  I can guarantee the Toughbook has no position information.  When i connect my iPad to the onboard wifi created by this Toughbook the gps comes alive.  It is absoluty as accurate as my Garmin hand held gps.  I am out in the ocean, there is no land based connection and you guys want to tell me this data is coming from the the wifi, hahahahah.

    Let us know when you have successfully circumnavigated the globe just using a wi-fi iPad. Take a sat phone and perhaps someone will come searching for you after you get lost on this fool's mission. Otherwise, we will all pitch in for a memorial wreath cast into the sea from the end of a long pier in honor of your ignorance.

    And that is related to the facts how?

    I wouldnt and don't use it for primary navigation.  These boats are properly equipped. The question was, does the iPad wifi have gaps? YFM

    Better tell someone where you are going so they can send out searchers to find you. Once again, the wifi-only iPads do not have GPS functionality.

     

    Read the specifications http://www.apple.com/ipad/specs/, under "Location".

    You are not dealing in facts. The facts are that Apple says that it doesn't have GPS. Period. End of story. Apple's facts don't say, "We fooled you. It really does have GPS, but we turned it off."

    This is not the first or last time specs are initially inaccurate vauge or missleading.  You're naive if you think Apple provides complete disclosure.   Tell me then where the data is coming from when

    N I am 20 miles off shore?  I guess I'll just have to take some videos for you'all.

    Don't take this personal but you're clueless.  The WiFi-only iPads do not have GPS circuitry.

    Give us a link for the time Apple said that a device did not have a specific part in its specs and later admitted that it in fact did? Just one will do.

    You think Apple would spend millions of $$ putting something in a product that is not capable of being used?

     

    The only comms chip on the wifi only iPad is for Bluetooth and wifi.

    There is an additional comm board with an additional chip for GPS and 3G installed on the 3G iPads.

    By the way, the ToughBook does have buit in GPS http://www.panasonic.com/business/toughbook/ultra-mobile-rugged-toughbook-u1-ult ra.asp

     

    Maybe yours does not but neither does the wifi-only iPad.
