GPS on AT&T Fuze with ROGERS?

Hey ive unlocked and flashed to a sweet NRG rom and love it. I just want to use google Maps (or something similar) to find my position on a map (turn by turn maybe?). I remember with my iPhone when I first had it the GPS worked great then one day I was never able to get my actual position (just within a certain amount of meters).
Did rogers shut down GPS?
Now on my new phone when I goto "GPS location" in google maps it searches for a satellite but doesnt seem to get my position (0)... Is there a setting I can turn on to allow GPS or do I need to cal rogers and rip on someone? LOL
keep up the great work guys!!!

I just turned 3g on and did the HTC GPS tool. I opened the port and started the test and then menu-Information and I dont seem to have a position.
any ideas guys? seems like rogers problem.

GPS on the HTC is using the basic GPS Signal coming from satellites. Are u outside or near a window to a fix ?
Look http://en.wikipedia.org/wiki/Global_Positioning_System
What u used was A-GPS what is assisted GPS with help from Cell Phone provider. It gives faster fix and a pseude gps in buildings.
Go outside with ur cellphone with clear sky view, start the htc gps tool and u should get position fix within some minutes or even seconds. There is no need for 3g because the gps itself does not need any cellphone connection. It takes satellite signals to calculate the position.
When u update quick gps it is faster in the position fix because it already knows some basic sat data. But still no phone connection necessary for using GPS.
The google map u then only see with data (3g or wlan) not because of the GPS but because of the drawed map graphics wich have to be loaded.

ok i will try the outside thing although I have the phone pointed to the window pretty much. Checking rogers website both phones only have a-GPS but I still cant get an actual location on either. Only about a 4 block square or circle.
EDIT: ok i enabled A-GPS on the touch pro and still no luck with google maps. It still seems to be looking for actual GPS

OK im managed to get it working. I changed the port to com5 and scanned found some sat's I had to change the bit thing to 56700 on com5 within google maps. Seems to be working like a charm!

Quick GPS fix. From Samsung!

Samsung just wrote that apparently the use wireless networks, which is the option above use gps satellites must be selected to get proper locks.
I was skeptical because i just assumed that when I went exploring I selected it, but it actually wasn't.
Put it on, and agreed to the disclaimer and then right away the maps got my location and the live wallpaper map got my location.
you'll get an email saying google knows where you are and yeah its pretty ****ty that you have to do this, but it does work. at least for me.

not a real fix, I've had that on forever and still dont get a proper lock

Confirming that this does seem to work. It might merit mentioning that I've also messed around with my GPS settings quite a bit as well.
Regardless, I got a lock within two seconds after opening Google Maps. Cheers!

The phone used networks to locate you. Not GPS.

This is to assist in the GPS lock. This is not a fix.

True it isn't a real fix, hence the "quick" fix in the title.
it's just another way to help maps get a lock.
obviously this won't help in no service zones but if you're using the data anyways might as well use it to help.
plus it unlocks all the fun location based services, and that maps live wallpaper is pretty freakin sweet!

This will only give you the location of the nearby cell tower. Unless you live under the cell tower all the time, I don't think this is useful. It might be useful for things like check the nearby stores and attractions. But will not give you navigatable fixes and does not speed up your GPS lock. If you're using Google maps, try to zoom out, and you will notice a big circle. Your location is anywhere inside that circle.
That's Samsung tip is pure BS and Engadet should be ashamed to even believe in that BS.

I not only allowed the use of wireless networks for location, but also changing the GPS setting to MS Based to allow for simultaneous use of triangulation and assisted GPS... before this change I NEVER got a successful GPS lock...after I changed the settings I finally can get a GPS lock after about about 3 minutes with direct line of sight outdoors.

Not quite. its actually doing cell tower triangulation, using the signal of all nearby towers your phone sees. In the city, this can be pretty accurate and is rarely off by more than a couple blocks. To see the accuracy, turn off GPS and click 'locate me' in google maps. The blue circle around your location shows the margin of error. The more towers you are in range of, the more accurate the fix.
As far as helping GPS, all this location can really do today is help you grab the most appropriate gps almanac/ephemeris info - if youve got an internet connection. I suppose it could possibly also be used in conjunction with the gps error in some kind of a filter to improve accuracy, but as far as I know that is not being done.

I actually started getting quicker locks with just using the GPS and having the wireless networks unchecked

Just an update:
I changed the SUP/LCP setting to Auto-config and the Operation mode to MS Based. I tend to get a gps lock within a minute or two with it sitting on my dashboard. I also tried it with the"Use wireless networks" setting turned off and it worked the same.
Also, I did try out the MS Assisted SUP/LCP setting and I was able to get GPS signal while indoors, but it was less accurate all around.

I'm not saying it's completely 100% accurate, but much in the same vein that an iPod Touch can get a location using just the wi-fi this is using much the same.
it uses whatever a-gps it can and then it helps with the cellular data. triangulation. it's useful and if it keeps getting me a signal then its all good

[i9003] Help me to improve my GPS! I read all guides and made the hardware fix

Hi to everyone,
I recently obtained an i9003 (It was probably manufactured a year ago, however I dont know to check it). I'm very happy with everything but the GPS.
I know that it has been debated a lot, I read all guides on this forum and others, I followed this one:
http://forum.xda-developers.com/showthread.php?t=1069416&highlight=gps+improve
and then tried with this one:
http://forum.xda-developers.com/showthread.php?t=1032034&highlight=gps+improve
I even installed GPS Aids v2 (but my phone is not rooted!).
I tried this fix (the piece of paper to put pressure on the antenna):
http://forum.xda-developers.com/showthread.php?p=13133654#post13133654
Then I decided to open my device, and modify for the connection between the antenna and the board, like explained here for a similar device:
http://forum.xda-developers.com/showthread.php?t=878970
You cannot say that I didn't use the "search" button
So far these changes were not successful, at least the performance did not change perceptively.
Near the window, in a tall building (6 floors above) I don't get any satellite on view, on the balcony I get 3-4 at around 30dB (and I get a lock in with a very poor accuracy, like 300feet). Is it normal that the number of satellites is so low? I was wondering if the LTO file is the correct one, it is called north-america and I live in Europe... Is it normal?
Do you think that rooting my phone would help? I'm happy with the stock ROM so I would not like to root it just for fun.
Which additional info do you need to help me?
Thank you very much,
Michele

Its done and verified.
Root, Flash XXXKB3. Tats it.
20seconds max to get gps.
I evn use GPS Aids 2, LTO method. 15seconds...
U did use search bt u shld hv posted it to one of d already existing GPS threads....

Do you mean that you're confident that my issue is software?
Thank you man!
Michele

I also tried all the software fixes mentioned here and nothing worked so i flashed XXKB3 and now it locks instantly. Also, since you do get a lock, i doubt its a h/w problem.

Yea i tried evry damn possible settings at LbsTestMode and evrytn up on xda bt ntn worked.
Finally flashed.xxxkb3 and bang! Saw my location using GPS for d first time thn..

You will need root access for this.
Download faster fix from market
Change the server to your country and set the server
If you are in India, server should be in.pool.ntp.org

So you think that the issue is coming from this LTO file? I will try and flash XXKB3 when I receive my USB cable

I finally flashed XXKB3, re-installed gps aids and faster fix, but Im not sure it improved the performance. On sunny day 100% clear sky, near to my window, I get 4-5 satellites max in view, it locks and unlocks intermittently and accuracy is 50m...
I set LTO file to europe also. Maybe my building is particularly rich on concrete?

U gt 4-5 satellites frm inside d bldg? Tats insanely freakish. I get 0.
Use GPS Aids 2 and Download LTO file.
Wen i first flashed xxxkb3, d gps locked in 30secs max, bt a few days later it stpd workig all together.
Gps Aids2 and bang!

No sorry, I'm in the balcony with a good view on the sky. What I meant is that I'm next to the building wall!

Wait for sometime
First time might tak smtime

Getting 4-5 sats in a balcony is perfectly fine. Doesn't mean hardware problem. But getting a fix using only one view of the sky is difficult.
Gps fix needs 3 sats minimum to get a 2D fix (without altitude). But the sats need to be well spread to get quick fix. Accuracy of 50 mts is best u can hope on non-us-military devices regardless of whatever accuracy reported by software or others.
Try a location where sats hav about 90 degrees seperation or more. Remember just 3 good sats are enuff. Most of the time gps rejects data from other non-geometrically-optimul sats.
Let me know if this post is any help.

My question is what is the max number of satellites were you able to lock given all ideal conditions, for me the max was 4 (took 5 mins to reach this figure under open sky) on this phone while Xperia arc and HTC wildfire were able to lock 20 satellites from the same location. Is the GPS on phone really a piece of sh1t ? Just confirm this and I am prepared to sue Samsung in consumer court over this.
Adding to this, while traveling in a vehicle the other two phones (mentioned above) were showing realtime progress of the vehicle on the road, whereas Galaxy SL was highly inaccurate and even the wrong position shown was not updated constantly.

In stock condition of d phone, GPS is really a piece of sh1t....

gps fix
hello
I hope i am in the good discussion,i am not very confident with the forum.
I have now 2 i9003,ifound the gps was working like my stand alone garmin gps,taking sometime a long time to fix some time not ,depending of the time it was swithed of or where i was.Like a gps without Agps.
So what i did is:
go to setting with dialing on the phone *#* #3214789650#*#*
I did some test and now for me it's obvious that the operation mode in application should be "MS assisted" (stand alone means that it doesn't use at all the data network to help for the first fix)
accuracy should be put at 100 ,it doesn't means that it will be more or lest acurate,i understood that if the value is lower that this it give data to your application(sygic or other).If it goes over 100 you will get something that "waiting for valid signal"
There you can do some test like i did :
-put opération mode to "stand alone"
-go back and "delete gps data"(so no satellites history)
-get position test ,in that case it can take 15 min to get a fix depending where you live.
go back to setting:
-put operation mode to "ms assisted",so it use satellites and network for the fix
-go back and "delete gps data"
-get position test,in that case it take less than 2 min.
If it's not the case check :
-go in supl/cp settings ,check the serveur ,i don't know if we can put the same serveur all over the world but i think yes,for me it work well with the default one
supl.google.com port 7276 ,secure socket off,agps mode supl
-remember you need to enable data in android menu :wireless and network,mobile network,network connection enable (that a traduction of my french menu)
for info,i have the original rom xwkb1
I hope it helps.For me it was night and day,now it works as well as my desire which was very good.

I just forgot to mention one thing,if you switch data to wifi and go inside house through a router,i think agps cannot locate you with the network,so they can't send you data,not sure about that,but that's the way agps works.(so no wifi)

For the 1st time i use GPS in SL.. I waited for 10min or even more with the orignal server which set to north america.. And i tot the gps for phone is so always like that.. but when i see this forum gps fix.. i just "whoa".. i dont even know there is gps problem in my phone..
SO.. i str8 root it.. flashed to XXKB3..
gps fix set to Asia.ntp ( i from Malaysia)
and i try get sattelite signal from outside of my hse with clear sky..
LOL --> result : none.. get 3 satilite but didn't lockon even with my wifi switched on
and then i go download gps aids .. switched on my wifi download the LTP file.
and try get sattelite signal
Result: 10GPs in 10 second and lockon immediately
I open my papago.. lOL.. position fix..
I didn't touch anything on the SUPL setting or standalone or wat
I didn't even go open my phone and put aluminium foil
Just like that..
GPS fix.. I think the gps aids is to use for searching satelite signal and lock on your position.. so when u open up the papago.. it will str8 lock on your position without waiting 10min or more..
Haahah..

edmund~ u r right!

GPS icon going super fast.

Tonight I noticed a pattern on my LG Optimus T running CM7 2.3.5.
If I disable "use wireless networks" under location and the GPS comes up to find my signal (I assume Google Latitude was calling for it even though it was backgrounded?????) it flashes super fast. I'm talking 12-15x a second. It's far faster than the searching for GPS icon we're all used to seeing.
If I re-enable "use wireless networks" it's instantly fine. If I disable it, it goes back to flashing.
I even signed out of Latitude to make sure it wasn't Latitude causing it to act up, but it did the same thing in both scenarios.
What could be causing this? I tried rebooting it, powering off and pulling the battery, etc. Any ideas?

Well, some new findings, and some new questions.
I have no idea what was causing the issue. Someone suggested I may have several GPS apps at once trying to get a grip on my location. I'm not sure what exactly happened but I ended up pulling a recovery from 10 days ago when I backed it up and it took care of the issue.
Moving along... I'm reading that "use wireless networks" helps the GPS antenna to find my location significantly faster since it can hone in on the area instead of the entire globe. Okay, fine. But I noticed something today. Previously I noticed that Google Latitude was wildly inaccurate. Further research after driving up and down the east coast reveals that Google Latitude (using only cell tower triangulation) is actually pretty damn accurate. In fact, it's always triangulated me within 2.5 miles of my location.
Here's the curve ball. Today I had wifi enabled. On a hunch, I opened Latitude. It said I was in Mineola, New York. Uh. No. I'm definitely in the very very southern most area of Pennsylvania you can get (Maryland border is a mere 5 minute bike ride away). I disable wifi, back in PA. I enable wifi, back in New York.
That said, it's obvious my wifi is throwing off the accuracy of Latitude. Personally I can't even find use with Latitude since I'm ALWAYS on wifi with work. Always. There are several buildings many miles apart I could be at, and since I'm always on wifi, the use of this app is really tanked if my wifi is going to throw off co-workers from knowing where I truly am. And this isn't Latitude's fault from what I can tell... something is goofed up in the database (whoever's database it is) that signifies my current wifi = New York when it should have been Pennsylvania, clearly.
So here's my next question - is it possible to separate wifi vs mobile tower triangulation? I noticed on my Android (Optimus T running CM7 2.3.5) that it specifically says:
Use Wireless Networks
Location determined by Wi-Fi and/or mobile networks
Keyword being... "or"...
Any ideas??

Anybody? No dice?

Strange GPS issue

My Nexus 5 running 4.4.4 has starting acting strangely this morning with anything to do with location services.
Only started this morning when I went to show a colleague the Waze app. Said my current location is Haworth, Yorkshire!?! I am actually at Watford Junction station Hertfordshire! Lol!
Even tried Google Now navigation and said 212 miles to home!!! So it remembers where I live?
I have never been to Haworth, let alone being there now.
Have tried rebooting phone, indoors and outdoors, turning off all location services and it is still showing wrong location?
Anyone have any ideas?

Have you tried in a completely different location, or go into Location settings and set it to Device only to force GPS and wait for a fix. It might just be your phone is defaulting to Wi-Fi location, and a new access point has appeared near to you that used to be in North Yorkshire!

Tried device GPS only, and not GPS/data/wifi, and picking me up fine. GPS on its own, mobile network on its own, both work fine, but not the 2 together?
It is very strange as it only started happening this week and only when I go into the mess/break room at Watford Junction station. And always Haworth! But now, as soon as I step out of the door, it sorts itself out within a minute or 2. But it does happens every time I go into there now! There is a wifi signal at work, but cannot pick it up in the mess room, so can't be that interfering?
It is not a biggy as not as if I need a satnav to drive my train! lol! And to see the weather, I look out of the door (no windows!)
