GPS over GPRS without GPS comunicator for DASH

I have seen on samsung simple phone i don't remember model... however so it has google earth and it was working by internet and was shoing my place in about 10Mtrs corency... so can we or do we have some kind of program to make that on HTS EXCALIBUR?????? i have tried google earth for smartphones but anyways it's requesting GPS device...

It is possible to triangulate your location to a certain (horrible) accuracy using Cell Towers in your area. I believe there are actually programs that do it (I have used one). The best accuracy i have ever gotten was within 150 Meters, standing still. That is the second down-fall..you can't use triangulation efficiently when moving (if at all...)
So unfortunately, there is not real good way to do this. For decent results, you would want a GPS.

I used Google Latitude which uses some sort of cell tower triangulations on my DASH and it works out pretty well. I was able to get within 80 meters and if you actually look at the Google map that is in the Latitude, my position is actually spot on.

My Google Maps Street View puts me within 50 meters.

Now is this using a DATA Connection? (I noticed the title said GPRS). That could make the difference. Whenever I tested out a program like that, i would be using little to no data connection, but if there is a greater stream of data being transferred, that may affect the response (or make it easier for the phone to identify the closest 3 towers)...

xXx
so what kn of settings I must give in GOOGLE LATITUDE that it shows me my place by GPRS? i pushing on MY LOCATION but program is saing that my location is unavalibe... I live in armenia can it be areason of error?

Virtual GPS
There is a program by Kamlex called Virtual GPS. There is a free version and a pro version. It uses no internet access and gets your location through the cell towers.
When using Google Maps, just set your gps com port to which ever port the VirtualGPS is using (usuallly 3) and it will locate you to the nearest tower. I will post the program here.

does gps only use any data? worried about overseas charges

i'm off on hols tomorrow (cuba) and want to log a few trecks with gps. mobile data will be off and airplane mode on.
in that scenario will gps count as data usage? i assume not but want to be sure
i plan on using mytracks or jogtracker to track my course. it'll only store gps data afaik but will be overlayed on google maps once i've uploaded it after coming home, or if i find wifi over there.

That won't work, It has to download the maps themselves from Google Maps and the GPS uses the web to assist it.

I used OpenGPS abroad (which works in very similar way) with Mobile Network disabled and was only collecting GPS data.
The app tracked my positions, drew the line but and Google Maps were not loaded.
So yes, it should work - as long as you keep Mobile Network disabled you will not be charged for pure GPS data usage.
And you can download the Google Maps layer once you come home.

Ignoreme - completely misread that...

thanks guys.
ferus, sounds like jogtracker/my tracks that doesn't it? i guess they all just show you pretty much the same info anyways
off to a fair few places and want to be able to look at maps when i got home and see where i trekked across.
hope this works

GPS abroad
I turn off roaming data while abroad as very expensive but I do use GPS and Mapdroyd for location based apps. Mapdroyd stores maps on SD card. Some countries have better detail than others. Works on aircraft as well.

No, GPS will work fine offline and My Tracks will be fine without any data connection. I've personally tried that, you just won't get an overlay but it'll record the tracks. You can see the track later with an overlay on My Tracks or on a computer.

what may happen is the google maps crying "need data connection" though. So you'd be better off installing the brut.mod anyway

got the brut mod.
anyway to download maps for a place before i actually go there? ot my sd card i mean so brut has all the maps anyway

[Q]Location Services Not working :{

I have turned on the location aware setting from the 'Settings' menu in my Samsung Focus, but still all apps including Bing Maps and Search
have difficulty in finding my current location(the latitude and longitude).
It used to work fine few days back.
I have tried resetting the phone to factory default, but still nothing happens.
How do I find if this is a hardware issue ?
How do I test if the GPS in the phone is working ?
TIA

same...worked the first time i installed wp7. now its not working anymore.

I have the same problem. When I am outdoors, I get GPS location fix in a few seconds, but when I am indoors Bing maps (even other apps) can't get my location at all. I believe indoors location should be found using cell tower positioning at least.

[Q] A-GPS on HTC 7 Mozart

I have used Xperia X1 for a long time, before I changed to HTC 7 Mozart.
When I used X1, with Google maps, when I stayed inside my house, it will automatically changed to A-GPS, with a circle around my position.
But with my HTC 7 Mozart now, when I'm in my house, Bing Maps only "Searching ..." with no result, while other apps like JustAnotherMaps, TAMaps, Advanced Maps Viewer also have no respond at all.
// of course it respond perfectly when I'm outside.
Is there any problem with my Mozart?

1. goto settings > system (pivot, you'll be on this already) > location... make sure it's on.
2. goto maps > hit the me icon at the bottom (middle one)
3. if fail, turn off and on the phone and try maps again.
if nothing is showing, try and go outside and give it a couple of minutes and see if it locates you.
if you do not get aGPS (it looks the same as what you described, with "my position" being a diamond with a circle in it) and you do not get a positive lock... you probably have a fault device and you might want to try and exchange it for a new one.
the aGPS is pretty much instant on my phone and the proper GPS is reasonably close behind.

oh really
Can you show me the image(s) that aGPS is currently working on your device?
Thanks

There's no specific image to show, it just determines location, that's it. It certainly works for me. Whether it does or not depends on whether the service Microsoft is using to determine cell Tower locations is available and is correct for your location.

I'm in Vietnam now, and I don't know that M$ have supported my country or not :|

That's the problem. The feature you asked is not a-GPS, but rather cell tower triangulation. It largely depends on whether or not the pariticular serivce (Bing or Google) has exntensive collections of cell towers in your location or not. In this case, it seems Bing or Microsoft doesn't have the database for cell tower locations in Vietnam but Google does.
aGPS is a totally different feature. It is used to speed up GPS initial lock using assitance from the cell data network.

found me sitting at my computer in under 5 seconds....
Guess if the gov't wanted to find me it wouldn't be hard!

Yes that pretty much explains my situation I described in other thread.
On my device - LG E900 - I get GPS position (outdoors) but no triangulation data.
I don't see any circle either. I live in Poland where Bing maps are pretty poor.
But GPS works.

I've searched, and I think that the only reason for this problem is M$ now doesn't have the data about Cell Tower in VN (and other countries)
Hope M$ will add more data soon.

Location wrong without WiFi/GPS/Edge

Hey guys,
I tried searching on google but to no solution.
The problem is when I switch off all forms of data except cellular coverage, my location changes to a City where I'm not at. I went to that place maybe thrice since I got the phone.
My location in Maps, Weather or even location saved along when I take pictures will be that other/wrong location.
Its easily fixable by just starting one of the data services, but why should I even face it in the first place.
Its happened on all ROMs and wipes don't fix it. Done a full wipe twice from cwm.
My GPS works normally when I'm using maps, it takes about 30 seconds to get a lock on my location.
Any workaround or solution or fix? (except for not keeping data switched on all the time)
Thank You.
Cheers.

Location without GPS is online service. I hope that answers your question about "fixing" it.

There's three things at play in plotting location: 1) GPS, 2), aGPS, and 3) Geo-location
GPS is the onboard chip functioning alone to pick up satellite signals and lock on them. You can test how well your GPS chip alone works by putting the phone in airplane mode and rebooting it.
All aGPS does is use a wireless signal (Wi-FI or cellular) to help the chip get its first lock faster. Once lock is established the chip is on its own.
From Wiki...
"Assisted GPS is a system which can, under certain conditions, improve the startup performance, or time-to-first-fix (TTFF) of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers."
Geo-location uses wireless signals alone to approximate position. Devices w/o a GPS rely on this for location based services.
From Wiki...
"Geolocation is the identification of the real-world geographic location of an object, such as a radar, mobile phone or an Internet-connected computer terminal. Geolocation may refer to the practice of assessing the location, or to the actual assessed location."
Once the chip locks, it memorizes the position of the satellites. So if you had your wireless on to get first lock and then turned it off the chip is still using the satellite locations aGPS helped it find. If you want to test the performance of your chip itself reboot it in airplane mode. Download GPS Test from Play. It'll give you a much better picture of what's happening with your phone. I just tried it on mine and indoors it locked and got down to 15’ accuracy in less than a minute. Conditions affect performance but, at least outdoors, yours should do as well or better than mine. If it doesn’t, it’s a h/w problem.

Thanks, that was a very informative post.
Well I switched on GPS and put my phone in airplane mode and restarted. The Maps App keeps saying "Your current location is temporarily unavailable" and I can't figure how to use the GPS Test yet.

Okay, I did get a lock-on from the Maps and the GPS Test app. I went closer to my window lol . Now I'll see if my location comes up wrong.
Edit:Location came up accurate in weather.
Edit2:Location is accurate in a photo I clicked with everything off.
By accurate I hope you understand what I mean, when all the data goes off the phone should still think its in the place/location where it was when the data was on. Ii.e Surat in my case. But what used to happened before today(gps in airplane) was without data the phone will think its in Pune, which is a 12 hours drive from here.
I'm not the only one who's faced this, some say its a bug in sense :/
Anyways here's a thread I saw earlier
http://www.htconesource.com/forum/htc-one-x-discussion/1042-incorrect-location.html
The answers the guy gets are retarded.

To be sure, are you saying that when only on mobile data and relying upon that, you cannot get an accurate location down to 1 KM?
If so, this sounds like a software issue or a carrier issue.
If your GPS has poor reception then I would advise getting warranty repair. It might have the same issue as the Wifi antennas do.

Yeah just so you know pure GPS is line of sight, you have to have a clear view of the sky to work (no clouds either).

No no.
My location when all services are on shows up fine. But say I have a weather widget and all my data services are off, instead of showing the location detected last when data services was on the widget and other settings will show another city.
I'll explain it with an example.
Lets have a hypothetical country with all the letters as its cities.
I stay in 'S' at present. I have visited 'P' and 'M' a couple of times but I'm back to 'S' now. On the occasion that my data services switch off, intentionally or because of weak coverage. Instead of showing 'S' as my location in the weather widget, app and geotag the phone will show 'P' which I had visited days ago.
