Thread: Poor Man's GPS

Feel free to move this thread if its not in the correct place.
How hard would it be to a have Maps use the iP's built in locater that 911 (and the NSA) uses? It wouldn't be super precise, but would be more than good enough as a starting point. What about via a website that pulls up a Google Maps link?
Just a thunk.

i logged onto my website using AT&T's edge and it states that im a visitor from some other state other than where i am right now. However when i was using the wifi with my local cable internet provider, and visited teh website from my iphone then it was very accurate.
So in reality i doubt this would be a very handy feature if you want to rely on AT&T's edge.

im smoking crack?....no the idea is great...knowing where u are based on your ip address is awesome and probably a good idea if your phone is using wifi.....but if your using wifi...im guessing you already know where u are, however if you are using AT&T's edge then your ip doesnt mean anything. I live in jersey but when i use edge, my ip address is based somewhere in maryland. So this poormans gps would tell me im in maryland when im actually in jersey.
How would that even be convenient? Honestly it doesnt make sense to me, but Alperovich if that helps you out in any way...by all means good for you.

It's not technically a built-in locator that's in a phone. 911 operators and the like have the ability to triangulate.
Any phone that has built in GPS that can utilize it has a seperate GPS chip built in.
On the other hand, if a third party navigator application can be written for iPhone, you could use an external Bluetooth GPS Receiver.[r a y n e]

I believe that an program very similar to Navizon would be pretty sweet with the iPhone. It was designed for windows mobile devices, but it acts as an software based GPS reciever for people who have no reciever and it bases its positioning off of cellphone towers and wifi access points. Then if we could implement that into Google Maps would be even sweeter. If it was possible to port this appilcation over to iPhone would be flawless.

Geohot had something like this as his next project, and he said that he gave up when he found out it would need extensive modifications to the firmware
He was going to do it via triangulation on the cell towers which is more complex than this idea, so i'm guessing it would at the very least be -very hard-

This is a lot like how Loran works. Assuming that the cell tower locations are all known, then an application could use the relative signal strenghts of the various towers that are 'seen' by the phone, and triangulate an approximate location. Take a look at the Cell Information in Field Test. At the moment, I have information about 7 cell towers. If we knew exactly where they were, it could be possible to figure out where exactly I am, assuming I didn't know already.

hmm this would be an awesome addition...

why not just bluetooth to an external gps device?

actually, i'd rather use real gps via bluetooth than rely on poorly triangulated positions, anyone whose ever driven in Europe will know how bad GPS cab be when it comes to your position on roundabouts or in ye olde vilages, also, google maps isnt great at point to point navigation, consider having to re-calculate a journey on route, on the fly based on google maps, I'd much rather use teleatlas maps on TomTom or equivilent

basally just something else so that we don't have to relay on something external or xtra but still have the option of having the external device also.

u need to call CTU and ask them to track u constantly.
In order to triangulate, u need to have made phone calls using other cell towers. Then they need something to keep track of which tower u used recently.
So, u will need access to their network servers, "No".
911 can do it because they r the POPO,
they can request these types of information under emergency situations or with a court order.
wait for that GPS transponder ... much more likely to happen than the former.Best Regards
