Please don't regard him as an "expert"; he's getting quite old and thinks that "fadiddling fumble-putz" is a more accurate description.

    Very cool. I pre-ordered my Ipad today (3 more weeks!) Even though it’s just a mock-up, the InteliSea app looks ridiculously cool and functional (bonus!), I’ll be all over that. Thanks for the update, Ben – keep us updated on the progress of these apps please.

    Keep in mind only the iPad 3G has a GPS receiver. So worth the extra few week wait while Apple gets FCC approval.

    Does the IPad have a GPS function? Someone commented on another site that even the 3G only has aGPS and if you are not near a cell tower it is useless. Here is a comparison. Any expert care to comment about how useful the IPad will be for navigation use?

    Hi Jack, It’s true that only the 3G iPads will have an internal GPS, but I’m hoping that Apple will enable Bluetooth GPS. I’m 95% sure that the aGPS in the latest iPhone and in the iPad can work alone if out of cellular range (there are several levels of aGPS as your link explains), but at the iPhone 3G and 3Gs seem quite sensitive to sky obstructions. I haven’t had much luck with them inside by boat or home.
    Maybe the slickest way to get accurate GPS on a boat is via WiFi to the boat’s sensor system. iNavX is the only charting program that supports this so far, but it’s also possible to get wind, depth, AIS, etc., which makes a navigation program more complete. All the apps mentioned in this entry are also connect via WiFi or cellular to a vessel’s GPS and other systems. So, yes, an iPad will be able to do navigation, in several ways, with several levels of sophistication.

    It is my understanding that iPhone uses Skyhook Wireless for the assisted GPS. My experience is iPhone 3G[S] does take longer (sometimes several minutes to acquire a position) outside of cell range, but it does eventually get an accurate position. Of course in cell range its almost instant.

    The nice thing about a WiFi connection to the boat data (GPS, AIS, Wind, Speed, Depth), is it is a many to one connection. That is several applications on many different devices can be connected to the data stream.
