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.
I'm using tomtom, so, I don't need access to verizon. Anyway, I'm with Telus.

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.
I'm trying to figure out if anyone else is having this problem.
Got my G1 on the 21st. been playing with a few things and the laundry list of UI annoyances is getting longer by the minute.
but overall quite impressed. Here's a weird one.
Google Maps (on G1 of course) cannot locate my phone - at all - with wifi OFF and gps OFF.
I am in a 3G zone. Google Maps on my HTC Touch worked fine (EDGE only of course)
So I looked around and found a reference somewhere stating that cellid geolocation does NOT work in 3G areas.
Is this true of all 3G phones?? If so it's very strange - because I like to keep 3G on but when I am indoors or for that matter when I want to save battery I turn off GPS and wifi.
So why the hell would they not be able to geolocate by cellid?
I tested it on my G1 and it's true - as soon as you turn off 3G (Settings->Wireless Controls->Mobile Networks) then cellid Geolocation works fine.
Just thought people might want to know and I'm curious if anyone else has the same problem.
Nick
I heard from a network engineer that all of the 3G hardware was rapid deployed and configured to minimum specs which happened to NOT include enabling aGPS. It was either an oversight or a timesaver. This will be fixed, it is a known issue. All the techs are still in the middle of the initial deployment and rapid expansion before the end of the quarter.
I HOPE to god Tmo can stop the ATT commercials that brag about the fastest network in the US after this quarter.
that only kind of makes sense...
I mean sure - it's all new etc...
but the point is that the network is not doing the a bit of the aGPS - google is.
Google does a lookup of the cellid in its database - and presumably does not have any information on the new cellids.....YET.
I just find that weird - I am in the metropolitan LA area and you would think with all the hoopla of this launch and the financial might of google they could have gotten it together by now - I mean these towers didn't go up yesterday...

erm, is that how aGPS works on the G1? That's stupid. I was under the impression that it worked like normal aGPS... I.E. -
Phone: Where am I?
Tower: You are @ 33.12345/32.12345 accuracy 2000 meters
Tower: GPS sattelites G51, T85, R14 are 3 strongest
Phone: Fed GPS data to GPS radio, warm start for 10 sec lock as opposed to over a minute for a cold start lock.
And I am also under the impression that alot of the 3G hardware wasn't configured with the appropriate data (position with est of accuracy based on closest towers and affinity and the 3 strongest GPS signals for that area). The issue was noticed and any new hardware should be fine. Problems will be resolved as the expansion portion of the project begins and all of the areas are revisited.

yes that was turned on on my G1 of course.
and no it still doesn't work.
nick
hey syrus - I didn't mean aGPS - I was just referring to the (a) part of the GPS.
i.e. there is no Phone saying "Where am I"
it goes
GMaps application: "What's my cell id?"
Phone: "It's ABC1"
GMaps application: "Hey Google dbase - where's cellid ABC1"
Google: "ABC1 is at 33.12345/32.12345 accuracy 2000 meters"
As to where I get my information from it's out of my ass
I accept that I could be totally wrong - but I assume that google does not go to the carriers for cellid information - it just drives around with the mobile vans and captures GPS data for Wifi and cellid simultaneously. Since the towers are quite new - their data has not been captured yet

Erm, you know now that I look at it Google is implementing SOMETHING new, I don't know how far they are taking it. Traditional aGPS has been around for a long time now, Google was never involved. I believe that at this point, with this version of Android things are still working the way they always have.
But! Did you notice the setting also indicates that the phone can find your location by wifi stations? I BET google receiving GPS data from users while they are connected to WIFI networks.
And then there's things like this below... ahh
http://arstechnica.com/news.ars/post/20071116-its-official-google-planning-700mhz-bid.html
Who knows, but I think as far as cell tower based aGPS is concerned android sticks with the basics. It's one data packet sent to the tower, and one back, rather than setting up a connection making a database query and receiving a reply.
They probably envisioned something like...
Phone: Where am I?
Tower: Shiii I dunno where you aaat?
Phone: Grrr, Google! I am connected to wifi access point "ATT" with SSID:12345678945 Where am I?
Google: Looks like syrusfrost was there last week, he was at 32.12345/33.12345 and he used GPS satellites.....
I really don't know how google is doing the Wifi geolocation, they may be parsing some of the wardriving databases out there for the major metro areas, hell when you drive with maps and wifi on you may be wardriving for google, wouldn't that be interesting...

Hows the battery life?
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.

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.
The phone seems to actually have A-GPS as well as the QuickGPS app - but don't turn it on! I was using Touch-IT AdvancedConfig when I saw the option, so I thought I'd give it a try ... turned A-GPS to active...
The GPS logs, then loses connection in a 10 second cycle - PITA! So I deactivated it again.
QuickGPS - I assume is responsible for this next problem... When I open Googlemaps without a satellite fix in a particular spot... it tells me I'm in Norway. I'm pretty sure I'm in Sydney Australia!
Could this be that the cell tower (actually it switches between 2, and they're BOTH in Norway) is in the QuickGPS database as being in Norway, when it's really here? Is it a Google maps error instead? Is there a magic portal between Sydney, Australia and Mölndal, Norway?
i have the second problem too..urs is a long way off tho, cause im in florida and it google maps tells me im in california, ive searched everywhere for an answer but there seems to be none
Google don't use QuickGPS to locate you but there own database of cells site locations. If your phone says your on cell 4322, with network x in country y they try to find where that is. Some of the info has come direct from the phone companies, other info is based on users with real GPS and google can try to put the GPS and Cell details together to get a good projection.
Errors when this occur will be down to Google's database being incorrect. The best bet is to make sure you have GPS enabled, so that you can feed back to google the correct location. The other option would be to contact them directly.
No-one else working around me has the same problem (they use different phones) so that would seem to suggest it's not Google's problem - it's the phone's.
Regarding QuickGPS.
I found out that my (wife's) Xperia sometimes fails to update A-GPS data.
"Update failed" and that may last for days!
ActiveSync, WiFi, GPRS access - doesn't matter.
Yesterday it somehow did succeed and I was happy as we need the working GPS for next two weeks.
I've been looking through google to find posts related to the google location service, but can't really find an exact match to my problem. All the N1 users post complain that the GPS is not working fine, which is not at all my issue.
About a week ago my location service using cell tower info stopped working. I used the Desire r21 rom and switched back to Kang-o-rama 0.6 and it stopped working around the same timeframe, however I don't think it is at all related to the rom switch.
I tried wipping all the data again, in hopes it was just a messed up setting with no avail. Also turned off the cell phone radio and back on (airplane mode). Tried to switch from 3G to 2G and back.
Anyone have an idea what could be wrong. Also, I read that google's service sometimes goes down and that could be a cause, however I would have imagined that some else would have complained by now.
Thanks guys!!
There are a whole bunch of reasons this could happen, in my experience, they're usually network related. New towers, repairing towers, etc..
My "My location" service went down for approximately 3 weeks recently. Wouldn't work on any of my phones, Android or WinMo. One day it just started working again.
Currently, when I am at the office, "my location" thinks I'm somewhere hundreds of miles from where I am. I suspect someone at AT&T entered the Lat/Lon of the main tower I'm on incorrectly. When I'm elsewhere in my city (closer to another tower) "my location" places me correctly.
Edit: That reminds me.. when I'm at the office and the phone is on WiFi "my location" knows where I am and it has very good accuracy (like within a block).. I always wondered if that was a result of Google Maps mapping Mac addresses, or if they can do that with IP..
So sure enough, I checked it out in San Jose, CA today at work and it found my location within a quarter of a mile. When I got home (Hollister), the google map ticker still shows me in San Jose and when I click on "My Location" in the menu it just stays in SJ.
But here is the even odder thing. My finance has an iphone and her location service is spot on in Hollister without the GPS.
I have seen posts saying it may be an old sim card, but this one just got replaced when I upgraded to the TILT 2 a few months ago.
I guess we will just have to keep waiting until the service comes back for us.
My N1 has been doing the same thing lately. I will leave work and about 1/2 hour later when I look at Google maps, the locator service still shows me at work. I wonder if the location service has a certain polling interval.
