GSM Triangulation - Windows Mobile Development and Hacking General

ANy one know of any virtual gps software that runs via gsm triangulation, other than navizon ? www.navizon.com/
Just think it would be cool for touch owners to have some form of software gps they can use hehe

I am using it (with GPS module) and earning money while traveling and geocaching ;-) You don't have to buy that SW to earn points, If you would like to give it a try, here is my referal ID 5D5C585C575E Thanks for points ;-)

the latest google maps (2.0? or 1.2?) can do that.. but it needs extensive wireless data connection.. and you must be in the US or some well street-documented part of the world..
it think the new GSM triangulation feature is called My Location..

Internal GPS

Does Anyone knows how to get the Internal GPS to work with Windows Live Map?
Thanks,
gpsone isn't in standalone mode so it cannot be accessed by applications
There are rumors that it'll be activated in the EVDO Rev A update this fall.
so wait... mogul has a gps?
it's built into the qualcomm cpu like the kaiser. it's assumed the gps shares the cell antenna since there's no gps antenna on board and the documentation states this is possible. the kaiser has the 7200 the mogul has the 7500. kaiser w/ test rom allows for the gpsone to run in standalone mode and the kaiser seems to have an antenna so it works.
as of right now it's assumed gps will work when unlocked but it's still a gray area; there may or may not be an antenna
The FCC application describes the Mogul as
"a CDMA850/CDMA1900 (1XEVDO / 1XRTT / IS-95A/B) Pocket PC Phone with wireless LAN, bluetooth, and GPS functions."
https://gullfoss2.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=391628&fcc_id='NM8TITA100'
the listing of gps functionality is ambiguous; all cellphones are required to have agps for e911 emergency in the usa as mandated by the fcc. gpsone is in quite a few htc devices but only a handful have antennas attached
how accurate is agps? versus standalone gps?
someone on PPCgeeks reported that Live Search was working on Sprint Moguls using tower triangulation. I'm not sure if this is different than AGPS, but it sure it neat to have location based services, even if accurate only to a few hundred yards...

A-GPS = tower assisted GPS.
http://en.wikipedia.org/wiki/Assisted_GPS
i had my telenav rep confirm when the rev a patch is released that the GPS will be unlocked as well.

All cell phones certainly DO NOT have aGPS. Please do not confuse aGPS for tower triangulation.
aGPS is assisted GPS meaning it uses the cell phone towers to assist an existing GPS chipset.
So if the Mogul has aGPS, then it has to have GPS by definition.
he is right though. FCC does now require that ALL new phones in the united states have GPS (to an extent) for at least e911.

Yes, I'm aware of the definition.
The way AGPS is described is similar to how articles are describing the technology Sprint and MS are using... and since every Sprint phone is mandated by the FCC to have 911 AGPS capabilities, I'm wondering if this is the same thing.

The Kaiser has a big "GPS" on the back where you can hook up an external antenna. No such luck with the Mogul.
But I still can hope that _some_ kind of GPS would come with Rev.A. Sucky GPS is better than no GPS...
I think you guys know as well as I do, that even if the phone has a functional gps and a antenna sprint will still never unlock it. Its not that they dont want to, they are lazy. There have been lots of firmware "updates" I have been waiting for on other sprint phones that they were going to release and never did.
As for external GPS recievers what do you guys think of this one?
http://www.semsons.com/wo44chawaauo.html
That supports A-GPS you think that would work?

if you are going to go with an external BT reciever any should work, since its not using the phones GPS at all
If you want an external, get a Holux M-1200. Tiny, cheap, and works amazing. I love mine!
ok, so any external gps will work? some of them say A-GPS compatible and others dont. Does that matter at all?

how to get gps on wing like dash ?

I find it funny that the dash is able to get the gps working on google maps and when it comes to the wing (MUMZZZ)the word.!
can someone help me if there is a logical answer and solution to my dilemma ...........
this is wrong in sooooooooo many ways. first, neither the dash (HTC excalibur) nor the wing (HTC Herald/Atlas) have built-in GPS.
Google maps uses data, does it not? So theoretically, anywhere you have a data connection, you can use google maps.
If by gps you mean an external gps, it's only a matter of tethering your gps to your phone, which is relatively self-explanatory
ok
so how is the dash able to track location on google maps also searches for gps and is successful . unless a buddy of mine has a special dash ..
i believe google just implemented a new service that uses cellphone tower triangulation to determine an approximate location. does it show your friends location as a dot or a dot over a larger, lighter colored dot?
I was going to post this yesterday, but didnt get a chance to..
GPS on the wing is NOT possible, UNLESS using a gps device.
THOUGH, google maps (the newest version) has a way of attempting to find your location without GPS. It uses cell phone towers to triangulate your posistion. This is not as accurate as GPS though, it can be anywhere dead on your posistion, or it could be 1500 meters off. it just depends on the amount of cell coverage in the area.
i dont know
if their using triangulation off of towers to get a position how com it doesn't work on my wing ? I have the new version of gmaps there has to be a way to implement a gps program into the wing come on people lets put our heads together something good has to come out off this

ofcourse you can "implement a gps program" just connect teh wing to a gps-mouse und use one of these:
- tomtom
- mn
- navigator
- destinator
- route66

Ways to locate current position(GPS, GPRS, SMS-locating etc)

I'm trying to develope an application for my Trinity, and I'm currently thinking of implementing a GPS function to track down my current position.
But: I've heard there also are other metods to find out your position, by triangling the GSM-bases, using GPRS-position(???) and also, I've seen a service that uses SMS(??? It says you can send a SMS to a server, and it will find out where you are...=)
Now, which one of these are pure misunderstandings, and which one does work?
I've heard of a application that that uses GSM-bases to triangling the position, and it actually works...
So my second part is, anyone knows how to implement this is C# ?
It can be done...

I can't help you on how to do it, but I know an app that does. Google Maps works this way. It finds my location within about 1Km using GPRS. I don't have GSP on my phone. It only works is some locations. For example, at my house (in a rural area) it doesn't work. I am guessing this is either because I have only one base providing service, or that base is missing certain features.
Good luck on finding a solution to implement this. It can be done somehow.

Great, that means that there is actually something called GPRS-positioning, now the 10 billion dollar question is how to implement this
Yes, the Google Maps "location" feature works well for me in USA. It locates the nearest cel towers to my device...good luck with your project.
i don't know about GPRS-positioning, but i do know for sure that Google Maps doesn't use it like PhilD41 said, Google Maps tries to figure out your location using cell phone towers around you. Cell Tower Triangulation, i think is the term. you can search that term and see how to implement it

Oh right then - Been trying to search bit for Cell Tower Triangulation, and found some interesting threads- unfortunatly for me, nonen that describes how to actually triangulate though But so far, I'm very thankfull for all the replies here
here is how it works:

Hi! Thanks for the reply, I belive this is something else then assisted GPS... Since the A-GPS, as you said needs a A-GPS server on the operator-side, while triangulation only needs three cell towers.... (Less accuracy, but still)

This is the kind of feature I want to implement, but I need to find out how to do this in coding...
Hi,
some interesting for you i hope.
As far as I can work out GoogleMaps uses the navizon database to triangulate your position. Navizon uses freely donates gps+wifi data.
Here's my slightly informed opinion, from best to worst
connected/Inbuilt GPS: most accurate u will get
Navizon: probably as good as AGPS but i think better as it triangulates on phone mast details and (if u have wifi built in) wifi router details (see website for this cool feature)
A-GPS: next most accurate you will get.
No such thing as SMS/GPRS location. This is in fact a service provided by companies who use a mobile phone operators databases to triangulate your position (API licenses cost between £500 and £2000 in UK PER operator!!!) . So not much better than AGPS but a method (with a cost).
Can you do this in c#? yes. download Visual Studio 2008 90-day trial edition and you'll find a GPS application ready and waiting. Its a bit buggy but a g8 starting point.
If you simply want to get gps position for an app without having to code anything, you might want to wait a little and download my next GPSSpot application. It will save the current GPS position to a registry key for other apps to use.

Wow! Nice reply sir!
But this really starts to stirr around my noodles - since I have a Iphone here, without a GPS, and it can give me a +- 100/200 m accuracy on where I'm using cell tower triangulation...
When it comes to the GPS-part, I've coded it finished, so I'm just so curious on how the author has done it... Is it using some sort of cell-tower location database? Hmm... I've tried to mail the developer, but without luck
But, when it comes to my app, I think NaviZone is the way to go...
if iPhone has wifi (which i believe it does) Navizone is the way forward. It will consume more power as your wifi has to be on. But it will only work in areas that have been "surveyed" by donating users.
(btw its also good to find local free hot-spots/unblocked wifi routers)
btw, cell-tower location databases have a VERY wide range in accuracy. Firstly its dependent on the accuracy of the cell knowing its own GPS position (big discussion came to my mind on how interesting that is, but I'll leave this out for now). Then dependent on the number of cells used in the calculation (the more cells the better.) So, inner city regions get fair to good accuracy, but out in the country accuracy drops to >1000m radius.
I'd be interested to know what the iPhone is like for accuracy out in the sticks, and whether they use NaviZone or a similar service.

agps rogers

how do i enable agps on my rogers elf plz help
Sadly Rogers touch Elf does not have GPS capabilities. The Vogue is the one with GPS. See Bell CDMA Touch otherwise known as the Vogue.
i know they dont have gps but i heard with 6.1 its to have agps
assisted gps ... which uses gprs not sat
Yes It Does

hi i do have software ,is call imobium,i dont know how to send it to u ,but it is such a gps on htc touch elf GSM from rogers. i bought one of those phones and i'm using imobium.
replay if u have another channel where i can send u the specs of the program and the posibility of sending u the program it self.
Good Luck.

If agps uses gprs not sat then would you incur heavy data use charges? I don't have any type of data plan (they are rediculous in price) besides, where I live, there is pretty much an open wifi hotspot anywhere I go so I have just been using the WIFI whenever I need to. I am interested in learning more. I did some googling and my understanding was that AGPS still required GPS. IF AGPS can work using GPRS Only, what can you do with that? Can you still use navigation software on the device and have turn by turn directions etc..., Can you use it to tell your speed altitude etc.. while driving? If you drive through a zone with no coverage, then AGPS would not work? There are several of these "Dead Zones" in my area in the North of Ontario Canada. (Dead zones for all cell phones no matter who your carrier is)
From what I have read there are a lot of phones that have AGPS however, most have it completely locked up so that there is no way to use it though. (Providers use it for their own purposes I guess - TO SPY ON US) I don't know about the Elf though. Haven't done that much research on it yet. Since there is no official WM 6.1 Rom release (For the Elf) to release the AGPS capabilities, maybe one of the custom roms from this site can do it. If it can be opened up for use with a ROM that is.
Assisted GPS, generally abbreviated as A-GPS, enhances the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones..... Taken from WIKI
http://en.wikipedia.org/wiki/Assisted_GPS
Funnily enough, A-GPS did actually come out as a data based gps solution back when EDGE came to the scene.
But suddenly phones started coming out with their own GPS units installed. UH OH, the carriers said. This imense source of data revenue, is now going to go away.
What to do? What to do?
I GOT IT! We redefine what A-GPS is. Instead of being simply data capable phone tracking system, we take phones with existing, and fully functioning GPS units, convince people that we are actually "helping" the performance of the GPS units with our networks and VOILA, we make even more money than before.
FYI, A-GPS was actually basically the same technology that Google Maps now uses for their "My Location" which is to normalize or coordinate, your location from several cell towers, and have a pretty good approximation of where you are.
All that was required was software (ie MAPS) that could take advantage of this technology that existed from when cell phones came into being.
That is why if you were one of the early adopters of set technology (originally came out with CDMA 2000) companies, you would have noticed that your so called "A-GPS" was as good as your reception was.
So really the more modern A-GPS, should be called GPS-A-CellCOMPANIESmakeMONEY.
But my suggested name did not fly so they decided to stick with A-GPS.

[Q] What's the best GPS Navigation map for the DVP?

I'm here at the US and I've seen some gps navigation apps that I can use offline in the marketplace and the different reviews on each one of them but I really want feedback here at xda. Is it Navigon USA/Canada, Turn by Turn, or something else?
One side question related to this. I know that DVP only has AGPS. Is it capable of offline gps navigation without using any data from the carrier? I don't have unlimited data plan.
You must be confusing what AGPS means, it's GPS + optional tower support to accelerate lock ons. All AGPS devices by definition also support GPS.
Besides that it depends on if you have an app that has cached/downloaded maps. It depends entirely on the app to support downloading maps ahead of time.
Try Navigon(Garmin), it doesnt req. gprs connected, good map's covarage/inteface.

Thanks for clarifying. I thought AGPS is just cellular tower support.
gmaps from the marketplace works well
I use Gmaps for long range navigation and Turn By Turn (free) once I get there(and locally) due to the limited mile radius of the free version. I considered the pricier options but this setup works fine for me.
Is there any free app to use in offline mode? Any of them working in Venezuela? I miss so much that feature that I had on my nokia n82
