Hello!
I'm just back from a trip from london. I brought with me my P4000 thinking that I would be able to use it's great GPS abroad.
It never worked once.
I thought this thing had an aGPS chip, meaning it was a true GPS that could be assisted by cell towers to find a fix faster. So, my understanding was that it should have worked abroad, albeit slower to find a fix then here.
As soon as I got back home, it started working again.
Any ideas?
Mod Edit: Moved from Titan Upgrading
Thanks!

If you were roaming overseas, then you won't be inside Verizon's firewall, therefore you won't have connectivity to the PDE server. The standalone GPS should have still worked, though it probably would take a lot longer to fix due to the fact you moved a great deal since the last fix. Did you try to use QuickGPS to download the ephemeris data? That probably would have sped up your fix a little.
I'm using tomtom, so, I don't need access to verizon. Anyway, I'm with Telus.
I've let it stand by the window for hours and it never got a lock. I didn't try QuickGPS.
Should I have switched something in the registry to have it work in standalone mode instead of assisted?
Well, i'm living in Republic Of Moldova. WE have no aGPS here at all, but i still can use GPS function on Titan. I have to wait about 1-3 minutes for lock.
I have installed DCD 3.2.6 rom and 3.42.50 Radio. Use SeaSGEE to download ephemeris data and Navitel Navigator. But Tom Tom and any other programs work fine too.
PS Sorry for my English.
I recall having a similar discussion in an earlier thread.
See if any of this info helps:
http://forum.xda-developers.com/showthread.php?p=2538917
If you do that right, i'm pretty sure it won't even attempt to connect to a PDE server (when u change GPSMode), so you should be able to get a *slightly* quicker lock, as it won't waste time looking for that server.
I do also suggest using some other tool like QuickGPS to retrieve the ephemeris data before trying to get a lock; it *should* speed it up, but I don't know how true that really holds.
Ok,
Thanks for all the infos. I'm going to Madrid next month, I'll try again there.
I was able to get GPS locks all over Europe no problem this past July.

Well it doesn't matter whether you have Verizon or Telus when it comes to aGPS. I was referring to aGPS. If you aren't inside your carriers internal network, then you won't access the PDE.
The GPS should still work regardless, just in standalone mode, which is why I asked if you tried QuickGPS to try and speed up the lock times.
I was under the impression that there is a registry setting for the global "zone" for our GPSr to look for and that it was set to US.
From the posts I reviewed few if any folks have been able to lock overseas unless they got locks while traveling
GC, have you found any settings in the registry for this?
In QuickGPS I think the setting is as follows:
[HKLM] - Software\HTC\QuickGPS\region
Its set for US for me here in TN and I think someone from Holland posted on PPCGeeks a long time ago NL worked for him to get a lock once he found and got it via trial and error...
I am sure you are onto something here
I think you guys are really onto something here. I have had the most frustrating time with my titan because of this very issue. I travel outside of the USA frequently and in all my travels have only managed to get a lock once! All through Australia and Thailand with no phone signal I was unable to get a lock with either flight mode on or phone mode on. Even in Taiwan where VZW has some modicum of representation (i.e the phone function worked but zero data) I go no lock.
gc was right about the agps thing. Outside of Verizon network you will not get assisted gps (although strangely when in "extended area" roaming inside USA it still seems to work).
in the end i tried a hundred things to get a lock including leaving the phone out in the full view of the sky for 6 hours. Nothing worked except the gps mode that scrawnyb talked about. I finally got a (very slow) lock after what seemed like hours.
I really believe that osteo's answer about the zone (i.e. "US" here in USA) is also part of the answer. I can only assume that the ephemeris data has to be relative to where you are on the earths surface, so the phone having some idea of where you are surely would help (especially without cell tower help from agps).
Targitai, if you visit this thread again can you please check the setting in your phone to see what zone setting you have that assists with locking. You need to look in [HKLM] - Software\HTC\QuickGPS\region and check that you are not set to "US" or similar.
I wont be traveling OS for a few months now, so I cannot confirm any of the above. I hope others who are traveling see this thread and can report back.
Thanks for the helpful info on this thread. This problem has been bugging me for months. Strange this is that my bluetooth gps never takes more than about 2-3 minutes to get a lock, even after crossing to the other side of the earth, over 9000 miles to Australia.
Well,
I'm here in Madrid now and it doesn'T work.
I tried changing the registry key of the GPS mode and it didn't help.
Any other things I can try?

How long did you wait, and do you have a clear view of the sky?
After traveling a long distance it can take some time to download the full catalog info on the satellites.
I waited a few hours in clear sight of the sky.
My old hp hw 6515 with a old stand-alone GPS chips can find a lock fine...
sorry, double post...
I have had my gps lock over the ocean in an airplane. I dont have navigation software installed other than google maps so I just used Visual GPS to verify I had lat/lon fix and a gps speedometer app to tell me I was going at the same speed the captain had said. No wireless data connection at all.
Hi, I have a similar problem, but when I'm in a no service area, the GPS locks in 2 minutes. When the phone gets a cell phone tower, never gets a lock unless I let him overnight catching sats. I'm from Venezuela, may be the cell phone towers or the network, I don't know, induce some kind of conflict in the position calculation of the GPS. In the flight mode the problem persist.
The other day the GPS had the weirdest issue. I was stuck in traffic and decided to turn on Google Maps to find out how long the traffic is going to be. To my disbelief, the GPS showed me in a different town and MOVING on the street and then onto some freeway about 50 miles from my location. I thought the GPS satellites are screwed up but my car was showing me in the right place (and never has made such a stupid error).
Makes me wonder if the GPS info is actually going to Google servers and coming back to the phone as I guess I was getting someone else's GPS data and the lines were crossed somehow. This continued to about 30 minutes as I was enjoying the error and wondering at the same time. Holding the phone out of the window and stuff did not work. Eventually I reboot (oops! I meant I took the battery out because HTC apparently thinks we never need to reboot te G1 so there is no PIN hole for reboot like most other phones).
has anyone else experienced the same issue?

The GPS is not being relayed to google... but google maps may be the thing that is wrong here. You can't get your "lines crossed" when using google maps but the maps may be downloading the wrong set. I know I have seen it do some weird things but that is expected to happen when you have several countries you have to have maps for.
As for the reboot issue... is it really that hard to hold down the power button? You do realize that the pin hole on previous devices is for emergencies only. It could really screw up the phone. Similarly like using your computer and unpluging it while it is on... or just pressing its reset button.
Maybe this is the reason for your problems with your G1.
I was just browsing my location and found that the location was in my local Radio Shack that was 2 blocks away. I tried to refresh but wouldn't allow me to.
G1 uses assisted GPS, which performs some calculations away from your phone. Could have been your A-GPS server was sending back some faulty data.
Some Application in G1 read Location info from Proprietary GPS Chip and also relies on Cell Tower GPS Coordination if GPS Signals is not available, in India my Airtel Company have Bad GPS Coordination in my Cell Tower, I Personally know which Cell Tower i am hooked to while i am at home but the Cell GPS Coordination is 8 Miles away from my Cell Tower.
Check that your GPS Signal were Strong and you have not just started seeing maps when that error occured.
I think it was stong. I had all my bars full and the 3g logo on it. Oh well I'll probably fiddle with it a little more tomorrow after I try to get a screen protector for the phone
I thought the problem had gone away until last night it happened again, with one difference. I still had me being shown 20-30 miles away (interestingly not across the globe but simply 30 miles away) the problem corrected itself after about 5 minutes.
I have a car GPS and a portable GPS and I have never seen this happen before. The issue is definately the A-GPS. I always thought during WAR the military may scramble the GPS data to confuse the enemy, I guess that is what promted Europeans to install their own GPS that is much more accurate than ours.
And there are controversies over this as well. Google is recording my location and my cell towers and IP addresses and URLs according to its NO privacy policy. This is definitely not fun.
Sending my GPS info to Google servers (which is in fact the case) without me knowing it and sending it back to my phone through internet channels it not something I am comfortable with. Especially if Google releases information to law enforcement one day that may be incorrect showing me somewhere I really was not at!

Where do you get your information? aGPS is for phones with GPS... it uses a data connection to locate you within so many meters than uses the GPS signal to pinpoint so you are located faster.

I have the same dxmn problem with the gps f-ing up. It started with RC30...When I was on RC19...I had NO PROBLEMS with gps.
It would pinpoint my location in 5sec. Now it's take 10-15min to pinpoint me. Google need to fix this fast.
whether it is related to this thread or not...A-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

same problem here. i also think it started with the update.
Guys, I am not wrong.
A-GPS as Google calls it (and there are other versions of it), is for phones without a GPS chip (thats how Google Maps find you on a T-Mobile WING), it started after an fcc mandate to be able to locate 911 callers from cell phone. It finds your location using a triangulation of the cell towers you are connected to and this particular technology and the extensive data that is required is owned by Google however Google may not call it AGPS.
http://www.techcrunch.com/2007/11/28/google-mobile-maps-pinpoints-your-location-without-gps/
Now it seems to me that Google is enhancing its data network of cell towers using our phones to collect location data. So it collects the cell towers we are connected to with the strength+ the GPS info from our phones and puts all this data in a server to that non-GPS phones using Google Maps can have a better triangulation as more data is gathered from across the country. Eventually the system could be perfected to locate any cell phone without a GPS chip or to locate a cellphone with the GPS feature turned off for privacy, and that is what concerns me.
When my phone shows me 20 miles from where I am, on the freeway, cruising at 55MPH while I am sitting in traffic on the other side of town, it concerns me.

Where are you getting your information? The link you provide just says they support phones without GPS but they never say it is only for phones without GPS. In fact it says that it will work on phones with GPS... that is what the whole article is about that phones in the future will have GPS and google maps will be able to pinpoint their location faster. Basically it says they are using A-GPS.
In the link above he links to http://www.techcrunch.com/2007/11/28/google-earth-heading-towards-extinction/ Which says people will be able to add their own commentary about places like a wiki. Nothing about using other peoples devices to send information for google to collect.
It also has this link http://www.google.com/intl/en/press/annc/20071128_maps_mobile_my_location.html Which is googles official press link saying it will work with both GPS and non-GPS phones by using the Cell ID and a special formula that google developed to pinpoint your location within a certain amount of distance. Nothing says it uses other peoples GPS signals. In fact it says "This approximation is anonymous, as Google does not gather any personally identifiable information or associate any location data with personally identifiable information as part of the My Location feature."
All in all I think you are misreading and need to look over your data again.

Regardless of above, and you may be correct and I may be wrong, but the thread is getting distracted from the main subject. My main issue is this: Why is the GPS reporting me in the wrong location, and even MOVING which is weird. It was pretty obvious to me from what I saw that the Google Maps software in my phone was reading someone else's location data from someone else's GPS. I could see the person move through the streets and speed up and slow down. This makes me wonder if my locatio data is being sent to Google servers somewhere and then back to the phone (and in some cases crossed over with another persons data). This feels especially more true because Google MAPS has slowed down dramatically from finding "My Location" compared to "pre RC30" upgrade and even compared to the GPS-Chop-Free WING and even my ancient car's GPS system.
Have you talked to Google about this? I think you are just speculating what you want and have a hidden agenda. Did it locate you within so many feet? or was it a real location? If it was a real location than it couldn't be Google as it only pulls the map the actual lat, long is coming straight from the sats... possibly it pulled the wrong location for that tower while using A-GPS and then this calculated the wrong GPS coordinates.
Since you don't know what or how A-GPS works this may be hard to understand. A-GPS works by using that method you described for non-GPS cellphones to narrow the search for satalites. This doesn't find your location it only finds the vicinity. You can see the A part of A-GPS work when it says your location within so many meters. This is what works on your wing. The actual pinpoint location is based only off the GPS and isn't sent to google. Google only needs the map coordinates to download. Your GPS is what tracks you on the map. This is why google maps always load in blocks.
To fully understand a map system you must learn how maps work and be educated in the art of cairegraphy
I think the real concern is that brooklynite was seeing himself moving through traffic while he was actually stationary. I can understand that perhaps the GPS got the wrong co-ords and the incorrect map was loaded showing him in another location, but you would still expect him to be shown stationary in the wrong location. So why would it show him moving when he was stationary?
The fact that he was moving on the map means the data must have been coming from another device doesn't it? How else could you explain it?
I would be concerned too.

A real location about 50 miles away from my location. Somewhere I have never been since I have had this phone so it cannot be using the old data in my phone as sometimes it shows my locations from "last night".

I always have the "use wireless networks" off, afterall, the GPS chip is one of the main reasons I switched to the G1 from my older WING.
....
I have to add that I am amazed by the GPS accuracy, it even notices when I cross the stree, turn into a driveway or the side of the street I am standing on. When I switch to Sat. view, it literally shows my exact spot on the sidewalk, not in the middle of the street like a car GPS does.
Probably getting too far off topic but car GPS units are just as accurate, it's just that most of them have a correction feature to fudge your position onto the nearest road on the map if for some reason it is not. For the most part a driver doesn't care where he is on the road in relation to the curb....only that he is on the road he thinks he should be on.
Started happening a few weeks ago. Applications that rely on the My Location service within Android fail because Android isn't receiving a location. Examples of this are the Google homepage and the multitudes of weather apps when set to Current Location. I'm inclined to believe it's a tower problem for a few reasons.
1. I have multiple G1's having the same issue while in close proximity to each other even after fresh Factory Resets on all of them AND multiple builds.
2. The problem disappears when switching to 2G (confirmed with a Market app called "Cellfinder"
3. I'll be at random places not associated with home and work and it will work.
4. The DDMS log tool within the Android 1.5 SDK shows that Android is at least trying to get a location lock but failing with various LocationManager errors saying no location was found.
5. The phone's are getting service and with BetterCut & Cellfinder I can see the associated tower's LAC and CID which leads me to believe that the 3G portion of the towers are simply not reporting location back to the phone.
My apologies if this has been posted before. I did a quick search of various child forums and did not see an active topic on the issue. I am hesitant to call TMobile Customer Support on the issue as I don't feel like RMA'ing a perfectly working phone(s). Can any technicians in here confirm or offer any insignt?
I have found out that other members here are having the same issue, such as dwang who led to find Cellfinder and the 2G solution.
I have the same problem. I'm going to try going to an earlier radio, to see if it solves the problem.

Let me know how it goes.
So this past week I was having tons of issues with the cell-tower triangulation on my Nexus One. I've tried multiple things such as restarting, toggling the "Use Network Location" and mostly everything short of resetting the phone to factory default.
So I was playing around in the Applications menu and decided to just mess around with all the items there. Then, after clearing the cache on the "Google Framework" option, force closing, then restarting my phone, I was finally able to get cell phone triangulation working again!
The problem continues though, because after said procedure I was unable to access the market, or the downloaded section of the store only had 2 items listed. So I did another restart, the market works, but the cellphone triangulation breaks again.
Does anyone have a solution?
well sounds like somethings haywire on the software side of things, i'd try a factory reset/reflashing your current rom etc. or you could just use GPS i suppose

Market problems are generally due to the ROM you're using, although most cooks have that sorted immediately. What ROM are you using?
And I've never heard of anyone anything on the Framework, maybe that in itself was kind of dumb? Have you rebooted or such to see if it clears up?
So what is the issue anyway? Where are you observing that cell tower info isn't working? And you've double checked, and maybe toggled off/on the setting for this?
OP, does triangulation work for you on EDGE?
I've been in this state (2G triangulation works but 3G does not) for about two weeks now.
Most probably a T-Mobile or Google data base issue...

This is true, at one point T-Mobile and 3G the lookups didn't work.. but I haven't heard this in a long time so I'd think
I really wish people would stop referring to it a "triangulation" though, it's estimation based on tower location and possibly data from Cell+Wifi+GPS data that Google has collected. There's no calculation going on.
I am glad someone brought this up. I thought it was just me.
'Estimation' works with EDGE on, but not otherwise. If EDGE is off, Google Maps takes me to the last estimated position!
I am sure something is broken in Maps.

OK, I believe accurate terminology would be "multilateration"
(there is an excellent Wiki article on this) which in turn is based on triangulation. The calculation is done either by the network, e.g. T-Mobile, or by Google based on the location of nearby towers...
I have the same problem as the OP. It occured since Tuesday of last week. I am also on Rogers in the Toronto and GTA region. Use wireless networks is checked under settings. The Enable location setting in the browser is also checked. However, when using 3G, location is unavailable when using the browser and it is also unavailable in the news and weather widget. RadioTime does not pick up my location either. In addition, when I travel into Toronto, the location in google maps is not updated to my new tower location. The location remains in Markham. Strange thing is that when I am on WIFI, location is available. I have tried using EDGE, same problem. I have also tried resetting to factory settings but no luck. I can confirm one of my coworkers is getting the same problem also on his N1. I don't think it is Rogers' problem since iPhone and Maemo users are having no trouble for location service on Rogers. I don't see how it is a problem on Google's servers either if location service is working for users of other OS. However, I don't know if any other Android devices on Rogers are having the same issues though. Can other Rogers users, Big 3 users, Wind/Mobilicity users confirm if their N1's are having the same issues? On a side note, my N1 is stock.
As far as the ROM/Phone. I am using the official FRG83D without any root or modifications to the firmware/bootloader.
It would not pick me up using Edge/wifi/3G and the only thing that did work was GPS. The weird thing is, it appears to be some issue with a service on the phone. The reason why I believe this is because if I went on the mobile Google, the page didn't ask me for permission to access my location.
After I cleared the cache on "Google Framework" and rebooted, everything worked fine and the browser asked me for my permission.
As madballs mentioned, it doesn't seem to be a Rogers issue as I was able to pop the sim card in my XPERIA and it was able to locate me just fine.
After going insane and going without sleep for the past 30 hours, I have linked the issue with the update to Google Goggles. Got rid of the update, location now works fine.
My N1's tower based estimation works ok on Solo (Bell's network). The estimatation is not as good as my Nokia N85 when I put the same SIM card in...
So I got into work today and same thing happened. The location services does not recognize that I am now in Toronto and not Markham. However, I tried out what the OP suggested and cleared the cache in the Google Services Framework and restarted the N1. It then recognized I am now in Toronto. This is quite strange. What does Google Services Framework do? And why would it not update when I travel into another location? It only stopped working last week. I will see if it changes back to Markham tonight when I get off work tonight. If it doesn't work, I will try deleting the Google Goggles update.
Same issues here ...
I am stock FRG83G on Rogers in southern Ontario. Been having this issue for a while but never bothered to look into it. I tried some of the tricks in this thread and here are the results:
- went to 2G - no improvement
- removed updates from Google Goggles and rebooted - no improvement
- Cleared cache and force stopped the Google Services Framework and rebooted and location is working.
I will edit this note if anything changes.
Update: Looks like clearing the framework loses your history of free downloads from the Market ... the paid items are still there.

Oops.. But try this, launch AppBrain, sync, then exit Appbrain and try the market again. I noticed by accident once after restoring all apps using Titanium Backup that before I went into Appbrain the Market didn't know about my installed apps and afterwords it did.

If you restart again, the Market will work correctly again, but the location services will break.
Same issue here on stock FRG83D since November 15.
I've tried both Rogers and Fido SIM cards. I've also done a factory reset and rolled google maps back. Nothing seems to resolve the issue so I've resorted to enabling GPS when it's available.
The same thing started happening to a friend's Acer Liquid E running 2.2 earlier this week. After clearing the maps data on their phone the positioning worked as expected once again but latitude isn't providing the correct location.
Today my N1 refused to update its position. After clearing the maps data it started to work properly.
Both phones are on Rogers and being used from Hamilton to Toronto...
Quick update. As I mentioned on post #11, I had to clear the Google Services Framework cache this morning before the N1 recognized I have left Markham and arrived in Toronto. I am in Markham now, and the N1 automatically recognized I am back in Markham now. Honestly, I have no clue what the problem is. As I stated, I have reset to factory setting a couple times the past week. I would tend to believe by reseting to factory setting is equivalent to clearing the cache. However it did not work then. So I dont know how by clearing the Google Services cache would work today. May be it is just a coincident. I will post again tomorrow when I am back in Toronto and see if the N1 recognizes the location by itself. Oh right, another thing tried was putting my friend's SIM card (he has a iPhone 3GS) into my phone, but no luck. I didn't bother giving him my SIM card to try since another poster on here said his SIM card works on his XPERIA.
beermike: Location services wasn't working for me on November 16th. Right before Eric Schmidt made his Gingerbread comment actually. I wish this hinted that Gingerbread was coming but then it's only us Rogers/Fido users having the problem.
P.S. This is probably not a Rogers issue. But I have to say, Rogers sucks. Too bad I'm on a corporate plan with them.
EDIT: I found another thread that some AT&T folks had this same issue back in May http://forum.xda-developers.com/showthread.php?t=679636
Restarted phone yesterday night and location services is not working today again.
I believe the correct term all of you gentlemen are looking for is "A-GPS" or "Assisted GPS".
Per the issue, are these results being achieved with the GPS hardware setting turned OFF, and the mobile network/AGPS turned ON, or are both of these settings turned on and still unable to find an accurate position?

No, it's NOT assisted GPS as that includes the GPS, yes? As mentioned, it's more of this nature: http://en.wikipedia.org/wiki/Multilateration
A-GPS is when your cellular provider offers the phone ephemeris data which reduces the amount of time the phone has to calculate the satellite positions and improves accuracy and the ability to maintain a fix because the phone already knows where the satellites are without downloading such data directly from the sats themselves. And in this case of course you're using the GPS, not an estimated location based on your nearby cell towers.
Assuming tower location is correct (and KNOWN...), if you only have one visible tower you should basically show up as being at or near that tower. If there are multiple towers, some set of parameters allows some estimation or predetermined location based on the results. I've read multiple times in the past that when the GPS is in use on a cellphone and My Location (what Google calls the cell tower location stuff of course) is in use, it will upload anonymous data to improve their database. There are multiple such databases, although most of them would only place you at the known location of the tower and not take into account multiple 'visible' towers.
Here's an OpenCellID lookup: http://www.opencellid.org/cell/get?mcc=310&mnc=410&lac=15913&cellid=50762 If you look closely, directly east, across the shopping center there and just into what looks like a bit of an industrial work area there's a square patch with a shadowy place; that's the tower it's referring to.
Greetings all!
Ever since updating from 2.1 to 2.2 my phone (i9000m) has not been able to acquire a GPS signal. I tried everything I could find on xda and online to no avail. While the 'Test GPS' application was able to identify satellites, none of my applications could (not even Google Maps!). Miraculously, I stumbled upon a solution earlier today. Once I turned off my Wifi (and I don't mean 'Use Wireless Networks'), my GPS started working instantly. The signal locked on FAST and was ACCURATE. I don't know why this happens. Maybe the Wifi interferes with the GPS? Anyways, I decided to share this right away in case it could help others with a similar situation.

P.S. My GPS settings are stock settings other than my Accuracy, which is set to 30m.
