How will a smartphone work as a GPS outside of range?
Out here in the boonies of Montana cell coverage is, uhm, sketchy

If your phone has a stand alone GPS, and the maps are downloaded on your phone, no cell signal is needed.

Thanks for asking. Don't just assume it can't be done as some people do.

Virtually all smartphones have a full GPS chipset in them. Some even also include Glonass satellite receivers. There may be a few smartphones that do not have the GPS, but I can't name any.
Most tablets also have GPS chipsets. Some, like some iPad WiFi only, do not. But most do.
Most people use their smartphone GPS for something like a Google map. Then, if you are out of cell tower range, you can't get Google maps to work, so people assume you have to have a cell tower for it to work.
But typical smartphones have storage, and there are app that you can lot onto them, that include the maps. Once you have the app and maps loading on the phone, you no longer need a cell signal.

So there are some exceptions, but basically you install an app on your phone and it works offline.

Your 'smartphone' is really a GPS unit with an Operating System and a phone chip added..

It is always a GPS, it only works as a phone when you have cell coverage..!

A real GPS, or A-GPS, needing triangulation assist from cell towers in order to get a fix on position?

Plus, when out of range, how does it pull appropriate maps since there is no data connection?

I just played a bit with my phone--by smartphone standarts an ancient Nokia N900, but I just love the damn thing...

I pulled out the SIM card, and i still got a lock in 12 minutes. I remember in the past waiting close to 20-30 minutes to get a position fix without cell signal.

I'd have to play a bit with the maps--I have Modrana installed and Sygic downloaded as well.

When I tried to use it in Europe it didn't fare very well... I might get a newer Android unit and give it a chance.

Where I find a GPS unit absolutely invaluable is in cities... Especially in European cities, I get lost in no time and it takes a lot of time to get out.

It is also possible to cache a good sized area (much less if it is urban) using Google maps before heading out and that will work too when you lose coverage. My Samsung Rugby Pro works well as a GPS in a car but the screen is way too small and dim to be useful on an MC on a sunny day so I still use my Nuvi 500 for that...the Rugby Pro is a good ruggedized phone but would definitely NOT recommend it for MC GPS use

I think its going to be more a transition over for traditional gps users. As there expensive GPS dies, they just won't buy another. Of course, those riders (and hikers, boaters, dog walkers, geocachers etc) that never owned a real gps, will just use the device they already own.

There's a lot of those people right here on ADV. In almost every thread about cell phones, there's some dumbass that pipes up about having no GPS when there's no cell service.

The ignorant masses are just that, ignorant. That's the reason they tend to stick with what they know. Mainly because they don't know ANY BETTER.

some phones have only Glonass (older phones) or Glonass & GPS

When you open your map app on your phone, the GPS inside knows the lat/long location. But, because the overlay (the map imagery) isn't stored in your phone, you don't see anything unless you're hooking up to wifi/3g and getting maps downloaded onto your phone as you move around. So, if you actually moved around with a half loaded map, the blue dot would move aswell. It's just that the map images aren't there.

You can download application that provide full maps to you. Like MotionX or Navigon. They store the whole maps on your phone. So, you don't need a cell/data signal. The GPS chip talks talks to satellites to affix your lat/long. The app takes this info and places you on the stored maps.
