Hello all,
I have been reading these forums for years, but never actually posted a new question.
I was reading the Wiki-FAQ for the Hermes and ran across the fact that there is actually a GPS chip installed, however is not currently in use. I read this to mean that we cannot currently use the GPS for map location.
My question is: What about e911? I thought that e911 allowed emergency responders to track the location of the phone? Isn't this only possible with GPS? I mean, cellular signal triangulation I cannot see being very accurate. Doesn't e911 rely on the use of GPS? How does an operator track your location?
Thanks for any responses!

Tracking can be by either Cellular signal (tower) or GPS, see here:

Is it possible that the GPS chip is actually enabled in our phones, but only for the purpose of e911?

No, it's not connected for GPS purposes and has no aerial attached. It is actively disabled for this function - not powered, pins removed etc. We know this because there was a serious attempt to get it working as a viable GPS receiver - but all these major problems were discovered.

I downloaded the new ROM and I can't get the GPS to work at all. I wonder if my unit even has the GPS. Is there a way to find out if it does. I know the model is a PPC6800SP. I wonder if the SP stands for something.
I believe all the 6800's have the same qualcomm chip. I had trouble the first time with google maps and gps, then I walked a couple of blocks away and it was able to lock on. Try taking the phone for a short ride and see if that works.

I'm sorry to let you down but I have a PPC 6800 and Yes it have GPS and yes you may download the las ROM from sprint but if you reed well there is no GPS ON right now the page say that for the 1Q of this year they "plan" to release a new ROM to "enable the GPS" the 1Q ends on march so we only have to wait...
To me friendly I don't personally I don't think they will enable the GPS because apparently the problem is no the GPS it is the antenna that in the original design was not design to be a ''Full GPS" it was design to be an "emergency GPS" and that is a big difference from a GPS to let the 911 know were you are between to antennas... and other thing is from you to get signal from a GPS satellite they are trying to get a "non real gps to work as a real gps" via software...
At least that is what I know about it I'm still waiting for the update... too...
For you to be happy yes we have a GPS antenna no full antenna but hey it is an antenna, we have the gps windows drivers for gps inside our phone, we have the com 9 open and sending info to the gps antenna, and we have a chip capable of prepossessing all the gps technology...
Pray and Wait.....

Im gonna agree with UltimatePG, try it again. Make sure you are outside and can see the sky clearly (shouldnt matter but sometimes it does). also might wanna try a different app to connect. try google maps or try wififofum. my gps works on com4, might be the same or different for you, im not sure.
I would say try the Sprint Navigation App, since it is the only one that has worked for me the first time and every time. Stand outside, not near a window, not in your basement, outside.
Then wait, let it get sats, it might take a few minutes the first time but it will work.
Good luck!

This is so last year....
It turns out,after all the people talked down to people who suggested that the mogul; had full gps,after all the snide comments and flames to people who suggested that it really had it,based on the chip specs,and after all the people who told others to "STFU,the mogul "ONLY" has AGPS and will never get "REAL" gps, that the test rom that was released does in fact enable full gps functionality (as well as the coveted EVDO rev A) that so many people wanted. I am typing this,connected to the internet over a rev A connection. I tried out tom-tom navigator sunday when I drove to see my GF. Its real,its here,and it rocks.

it has GPS in it. I ended doing a search for "gpsinfo.exe download" (no quotes) on google and found a small app that displays your satelite info. Some people have reported that it can take up to 45 minutes for the phone to get a good connection. Mine took about 20 minutes before it found any satelites, now it finds them very fast. The first time takes awhile. So grab a cup of coffee and fire up either google maps or gpsinfo and stank outside for a bit.

Yes I try the new rom and iGuidance works find but google earth no and other programs seems not to work right and the ROM have many stability problems I hope when they release the final version will be more stable....
Sorry for miss informing.... but I still think people can start working in a more intelligent way like for example the ATI drivers.... and many other thing companies do not take the time to make them work find from the first time...
Why if you have a Phone capable of GPS why you just no enable it before marketing, why if we can have ATI acceleration we don't...
and let me tell you I have tested the GPS of the tilt and works much better than the mogul new ROM....

wow -- between you two messages you said two totally different things. First you said you don't have GPS and Sprint will never have it, then you say you are testing it and that you have even played with a tilt.
Strange -- I'm confused.
i read something a while back about someone who had disassembled a mogul and found it just had a dummy antenna where the gps antenna should be, i cant find a link now because google only shows all the new pages with info on the leaked update, but i suppose it could be possible there are some moguls out there with gps but no antenna
i too think its funny about all those snide people who said it only had agps. i hope they're going back to take a long look at their posts..ehheheh

I'm so sorry about all people confused... Well Yes I have tested the Pre-Release of the new upcoming ROM from Sprint.... I have a PPC 6800 (Mogul) I have tested the HTC Tilt that my friends own... The gps in the 6800 is working kind of slow in comparison to the gps of the tilt my gps is working in COM4: at 4800 bps
and the GPS in the tilt works on COM4: at 9600 bps the New rom for the 6800 have a lot of problems it have problems connecting to the internet... have stability problems, some times the Display do not turn on, some times tis freeze, some times you are in the middle of a call and you los the audio... and many other problems...
The slow speed of the GPS let me thinking about the antenna problem.... I have seen 2 different models of the Mogul I don't know if one of the other have no GPS or what...
But When I write my first post I did no see another post in wish is available the new ROM I only have the facts of the problems with the GPS and the antenna Now I'm running at
ROM 3.16.651.0
Radio version: 3.27.00
I strongly suggest for everyone to wait until Sprint release the Final version of the ROM like they say they will on March... if it happen...
Any one wish need some print screens I can e-mail them....
Thanks
Low Baud Rate
I wouldn't be too concerned with the low baud rate of the GPS.
GPS only needs to send a minimal amount of data...and 4800 bps is more than sufficient to handle the necessary data.
As far as the stability issues, the ROM being used is nowhere near a "final product". I would also attribute most of the problems to the ROM and not the GPS
As far as the lack of support for GPS from HTC, you need to remember between Sprint and HTC, there have been a lot of issues with supporting features that were built into the phone. Remember the 6600 EVDO issue?
Now, to the guy who cannot get GPS working.
Load google maps, does it say "acquiring satellites"?
It does? Good...
Now, place your phone on your car's dashboard.
Drive around for 20 minutes(hopefully away from tall buildings).
Now, pickup your phone and look at it. It should have your position.
GPS signals are VERY weak. In comparison to most other signals, the signal degradation is INSANE. However, it is much easier to keep a signal once you have acquired it. So, once you get that signal, it should be easy to keep locked
Also, after you have acquired satellites your GPS can do a much better job at 'guessing' what to look for. So when you turn it off and then turn it back on, it can guess at GPS satellite location(I am severely oversimplifying everything).
I have loaded two GPS roms. Each time, I had to drive the car around to get a signal(even after standing outside my home for 20 minutes). The car is more comfortable, easier to maneuver into an open area, and it should work within a few minutes.
I was going to take apart my sprint touch but don't have the right size torx wrench. Can anybody take some shots of the inside to show where the GPS device might possibly be.
I didn't see anything in the FCC filing so I am starting to get doubtful that GPS is included and fear it may be telenav that Sprint will use instead.
MSM7500 Chipset has the GPS chip inside of it. Go check qualcom's site, and you will see it has the GPS/REv. A radio in it. Then check your phone's chipset in teh phone's menu. There you will see it runs the MSM7500.. So yes it has GPS. THe only question is wil sprint limit its capabilties???
The GPSOne chip is integrated into the MSM7500, but if the Touch is missing the GPS antenna it could still be a no-go.

They took pictures of the inside of the Titan and said it didn't have a GPS antenna, but were wrong. Either the CDMA or the Bluetooth antenna is also the GPS antenna. I can't remember which right now.
We had this issue with the titan as well. People would suggest that it had GPS or ask if it would be activated and of course people would respond in a condescending tone telling them it didnt have it. It turns out it does and I strongly suspect that the Vogue has the same,as it is a very similar phone. In fact,I read that someone got the vogue radio rom to work on the titan. If thats the case it might work the other way and you could get GPS and Rev A now,by using the leaked titan rom. (Of course you could brick the phone as well) I dont know all the specifics,and certainly dont know that much about the vogue (I have a titan) but it might be worth checking the titan forums.

** This is a challenge for Musicman247 !! **
I never meant to imply that the Touch doesn't have GPS capability, just that it is not 100% certain yet. People did miss the GPS antenna on the Titan, but it was there. I really do hope the Touch is GPS capable, my wife has one.
JDillard and a couple others have said they are running radio 3.27 on their Touch. It doesn't appear to have done anything though. No Rev A and no GPS still. It appears there are some critical components built into the ROM that enable those funtions. Seems strange that radio 3.27 will run on the Touch without ROM 3.16. On the Titan you need both installed to even get the phone to boot.
Here's hoping for GPS and Rev A on the Touch soon!
GPSone antenna
The reason why you couldnt find the antenna inside the touch is because it is a GPSone chip, not regular GPS. It uses the cell towers to make an approximation of where you are, it is not like regular GPS as it does not communicate directly with GPS satelites (hence no need for a GPS antenna).
GpsOne uses A-GPS, which means satellites plus cell towers. This improves positioning information when satellite signal quality is poor, especially when indoors. You'll still know where you are in the middle of the Pacific; you just won't be able to make any calls.

That is why when I get a fix and go in the house it shows me going across the floor inside the house. This is with Google Maps turned on and use GPS checked and then show my location. It does work and can get a fix most times with many satellites but sometimes it just won't work so it is really iffy. I get a fix about 70% so not too bad. I am with Alltel and have the MP6900 HTC Touch and think this is the Vogue but have never found out for sure.
Here's what happens... if I have just GPS enabled (no Wi-Fi), and I tell it to locate my position while I'm at home, it tells me I'm about 5-10 kilometers away. It's in the correct town, but isn't near where I actually am, and I'm standing right in the open, no buildings or anything.
Now, if I enable GPS and Wi-Fi, it tells me I'm currently where I USED to live, which is about 50km away from my real position. The place it tells me I am is actually right near my gym and where I used to live, but I haven't lived there for close to two years but I still frequent the gym.
Anyway, I'm totally confused. I could understand that if I enabled my Wi-Fi and it's telling me that I'm near where I used to live, it could have something to do with having the name of my wireless router cached at that location, even though it hasn't actually existed at that location for two years. What leads me to believe that this is some sort of caching issue is that if I am at work and use the GPS (or anywhere else I don't frequent for that matter) it locates me fine, instantly.
So... what can I do?
Anybody have any idea? This is awfully frustrating...
You could try using GPS status from the market to reset and download your AGPS data?
That fails i would backup data and factory reset as symptoms are of faulty settings . You could also replace the modem .
jje
I'm also having issues, "GPS Status" app sees 10 satellites but never locks. This is outdoors.
With your Wifi location issue, I think that's because the google vehicles collecting street view data recorded your wifi SSID to be at your old house, which is why it thinks you're there.
EDIT: I should also mention, mine worked fine before rooting, then I used Chainfire's kernel to root and I have the issues that we're seeing (JP_XSG_KG2 and ZS_OZS_KG2).
One of the reasons I'm waiting on a proper Canadian Kernel to use.... too many unknowns.
Fixed!
Using a different kernel and ROM (XXKG6, Android 2.3.4):

GPS locks within about 5 seconds outside and network speeds seem to be the normal for Rogers.
Do you have a working 3G connection?
So, I downloaded that GPS app and did everything that it had available... nothing really helped. When I'm anywhere but my house, the GPS locks fairly fast, but can still be somewhat slow.
I believe I was having no issues as well before rooting, and I used CF Root as well. I obviously agree regarding updated firmware from Samsung/Virgin... I'm sure it could very well resolve this and some other issues.
I have a 3G connection... it's always listed as H+ though.

Yep! It indicates 3G when idle, and when I'm using the data connection it switches to H+. Rogers download speeds of ~4Mbps.

Ok... let's asume you're not trolling here, altho this kind of question is sorts of "I don't have gas in my kitchen, will the electric stove work and how"... and I'm kinda bored, so I'll do the explaining.
GPS or Global Positioning System works via more than 30 satellites in the orbit of the earth and devices with GPS have a chip, that can recieve the electromagnetic radio signal sent by the satellite, once the chip aquires signal from at least 3 of the satellites it's able to pinpoint your location via a method where it finds the point where all 3 of the satellite signals collide (your location)... Imagine drawing 3 circles and all 3 of them touch each other.. the point where they touch is the point you're at, and the more satellites you're connected to, the better is accuracy of the location.
WIFI and mobile network (edgem 3g or LTE) aren't really able to give you accurate location, altho, if they are available, both could be used to give you aproximate location (same technique as GPS - 3 radio towers and you can tell where aproximatelly in between them you are), to help the GPS find your location faster. There should be at least 8 visiable (reachable by GPS) satellites in any given time anywhere on the earth.
EDIT: as I could asume from your post, you don't know what WIFI and LTE are, so I'll do quick explaining to you
WIFI is just a standard, being used, to wirelessly transmit data fast, but in short range (ex. you router at home, transmiting data from your modem, or even your phone as a hotspot, transmiting data it's recieves and sends to the radio tower of the mobile operator)
So we get to LTE, which is also a standard being used for the 4th generation of mobile data transmiting, which works via radio transmiters by mobile operator.. those are placed on the ground and you can pretty much spot them everywhere (big towers with antennas)...
So conclusion: a GPS device does NOT need LTE or WIFI to operate, but it can use them for quicker GPS operation, if the GPS device supports aGPS standard ( more info: https://en.wikipedia.org/wiki/Assisted_GPS )
If you want more info on GPS: https://en.wikipedia.org/wiki/Global_Positioning_System
ok thanks
