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.
Hi all,
I was just wondering if anyone knew why my Weather tab has suddenly started mis-reporting my location as Oldham. I'm actually a few miles away. Up until recently it always found and reported the location of my fairly small home town accurately, and worked great elsewhere too.
Now however, it keeps defaulting to Oldham. It also sometimes says Rochdale, or occasionally Manchester. These are inaccurate too. Just a couple of weeks ago it always got my location right, but now it hardly ever does. It seems to have suddenly lost its ability to pinpoint my location, so simply defaults to a nearby large town or city, despite the fact I'm miles away from them.
Incidentally, the four dots around the GPS logo (next to the name of My Location) no longer 'gyrate' while updating. They used to rotate in a 'wobbly' orbit around the globe logo in the centre, presumably to indicate GPS activity. Now they just spin in a fixed orbit around the central point (GPS still works fine in TomTom7 and Google Maps etc).
I have Location Service enabled, and allow it to gather data on my location at any time. The problem remains the same whether I'm connected via WiFi or HSDPA, or both.
Does My Location actually use GPS, or just cell towers? Like I said, it worked fine up until recently. I know people have had various problems with the Weather tab, but I can't find anyone with this exact problem on here. Any advice would be gratefully received.
Thanks,
Rob.
Mate, the GPS is the least of your worries. If Oldham is the nearest place of interest to you, you should move home!

But on a serious note, weather worked fine for me, until one day I did a hard reset.
Now I have not once had the correct location at home.
Weird ay?
I suspect that your weather location is tied to your local cell.
GF is on t-mob and I'm on O2, our HD2s regularly report our local weather location as being in different places even though we're both on the same sofa, my guess is that it depends on which cell signal is strongest, maybe your local one is temporarily down?

That's my point; Oldham ISN'T my nearest town, but the damn phone keeps sticking it on my Weather tab anyway. My phone has never even been to Oldham!
My Desk in work officially sits between Brockworth and Hucclecoat. I get different locations at each side of my desk. It does sound like its a cell tower problem to me.
Yup depending where i am in town i get either north lincolnshire or appleby its very annoying
it doesn't use gps...uses information from the cell tower your phone is currently using. If that cell tower is labelled Oldham, then that's what you'll get.
I get saddleworth most of the time. I got tameside once which would be better
if i am getting hsdpa signal it's correct if i get 3g signal it reports wrong location.
Same here. I often get Poplar when I'm travelling through Hackney.
I experienced the same problem. It's weird that when I use Wifi, the location is about 30 miles away from where I am. But using 3g, it points to a couple miles away which is acceptable
here is one for you.. lmao
If I am upstairs at my computer I get Richmond, if I am in the guest room dirrectly below my desk down stairs, im in Preston. now if I force it to update, im in Smithfield until I get back to my computer and wait 15 minutes were I am once again, back in Richmond...
at leasts yours works, my location hasnt worked in the 2 months i had the hd2 works fine on my hero lolol

Funny, it's the other way round for me - it's generally accurate if I'm getting a 3G connection, but when it's HSDPA (most of the time) it usually shows up wrong (I'm on T-Mobile).
Anyway, thanks all for the replies. Nice to know it isn't a fault on my handset at least. Doesn't sound like there's much we can do about it though.
Cheers,

It'll depend on which cell it's connecting to then. It's probably connecting to an H-enabled tower which is in Glamorous Oldham, and the fallback cell is just 3G/GPRS and closer to home.
i have the same issue, somethings its ok and recognises my location as swindon but in my house it says im in wroughton which is a small village about 5 miles away.
I had a problem like this, but mine was 100 or so miles out.
I found out it was to do with where my time settings were.
I chose manchester (closest major city [and home city for me]) for my time.
So it made the weather show manchester as my location.
now i've changed the time to my location, its the same in weather.
dont know how much use that is to you, worked for me though.
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.
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?

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.
I'm in South Florida and when I update weather or location in maps, half of the time it will say I'm in Wilson, OK. My dad just got the MT4G and his does the same thing.
Any ideas? Thanks. (We both have 2.2.1 and latest updates on everything).
How is your location being determined? GPS? Mobile networks?
Usually mobile network, but I think its happened with GPS too. However, once I need to get directions from Google Navigate, it gets the right location. But until then, my weather is wrong, latitude will be wrong, etc.. I usually keep GPS off until I need Navigation.
That's definitely odd. Yeah, I keep my GPS off pretty much all the time - unless an app requests it on-demand. My weather is always found, perfectly. What's interesting is that it's happening on both your and your dad's phone. To me, that almost seems like the tower it's connecting to.
Shoot, it could even be a "bug" in the HTC weather app/widget that based on certain location data, it displays a completely different value (city). I'm only speculating.
If it was just your phone, I'd be inclined to say there is a hardware issue. I have had 3 MT4G's in my hands + my fiancee's and none of them have ever once experienced any issue such as this.
Possibly anything to do with the APNs (Access Point Names)? Check Settings > Wireless & networks > Mobile networks > Access Point Names. As far as I can tell, this is supposed to be set to T-Mobile Data.
Sorry I can't be of more help!
I know, weird. And we are on T-Mobile Data for the APN... Maybe it is the tower... ?
I have the SAME issue, it isn't as drastic, but everytime I try to go into "Maps" application to search for stuff in my location, it "finds" me at a place I haven't been for like a week, however... again, as soon as I use my turn by turn, it locks onto where I am and gives me legit directions...
My MyTouch 3G did that, said I was on the other side of the state. It probably has to do with the tower you're hooked into, because mine would only do it at work, not at home.
