GPS Showing me in the wrong location

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!

CORRECTION: A-GPS is for phones without GPS. It does not apply to this thread.

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.

http://www.apple.com/iphone/features/gps.html

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.

HTC Snap, GPS not detecting satellites

I can't get a satellite lock on my HTC Snap.
I have enable "use GPS" in google maps. google maps will search for satellites and after sometime come back saying weak signal & some recomendations to look for clear view of the sky.
Garmin XT also can't search GPS satellites. I install GPS Test, it seems that there's a GPS hardware but somehow the signal reception is super weak.
I have sent my Snaps to HTC service center and the best thing they can do is change the mainboard. This also show no result.
Anybody, please help. i'm starting to get frustrated with this GPS issue...

Bing GPS
I use the Bing app and have similar issues establishing GPS signal. This is my first GPS device so I'm not sure if this is normal, or if the phone is crap for GPS, or if I'm doing it wrong. I try to keep the QuickGPS updated, but that doesn't seem to help. I thought AGPS was supposed to be fast, but faster compared to what? Maybe this is 'fast' for GPS. I have seen friend's full on GPS devices and they seem to pickup pretty quick. So... who knows?

One thing to definitely try is make sure quickgps is up to date and automatically downloading. garmin could NOT find my location without that up to date and it would show one red bar signal strength. once i loaded up quickgps, updated it, and ran garmin again, full green signal.

It's The GPS Hardware ...
I've tried it all with my Dash 3G -- and concluded that it's the GPS in the phone that is garbage. I've since switched back to my trusty OnCourse Bluetooth GPS and I get a lock in Google Maps in less than 30 seconds and in Garmin XT in less than 10. IMHO, the GPS is certainly a weakness on this phone.
It finally sunk in for me when I lost signal 9 times while walking a few miles down Beacon Street in Boston. Holding the phone in my hand it kept dropping the signal over and over again. So I gave up. Built in GPS is handy in a pinch (when you have 30 minutes to wait for it to find a signal) but for serious navigating I use my Bluetooth GPS exclusively now.

No true at all. the gps in the Ozone is amazingly fast.

I completely agree. Simply because something is not working like it should for these others does not mean that the GPS is not good. I use garmin xt with my ozone and its is extremely fast at updating my position as i'm driving along.

Problem solved
Let say that i'm in a really bad luck. this is my first GPS device and its not working. After the 2nd time come out from the service center (2nd concecutive mainboard), then the GPS is functioning, normaly....
my maple can get lock on GPS signal quite fast. with AGPS updated, it can get signal lock within seconds (given you have a clear sky view). i found that it could takes some time for Garmin XT to get GPS signal, so I use GPS Test to speed up the process then start the Garmin XT.
so for those who can't get GPS signal. it's definitely your hardware. I also found that the online customer service officer at HTC is just a mere lips service / useless. they keep telling me to be patient and patient without real action.

There's a free GPS testing tool for Windows Mobile called GPS Test. Once that set up, you can find out which serial port is used by the GPS receiver in your Windows Mobile, and set Google Maps GPS setting accordingly. Once it's set up, Google Maps can easily find multiple satellites if you're on open space. Once it's using GPS, your location on Google Maps will be a pin point, rather than a large circle denoting your approximate location.
PS: Found out with GPS Test that my GPS receiver in my Snap is using COM4 port at 9600 bps
Sincerely,
Paul Pambudi

WIND Mobile HTC Maple users not getting GPS working PLEASE READ!
I went through four HTC Maples (two accounts each 1st phone was a warranty exchange for another non-related problem). Each of the four Maples could not lock in single GPS satellite. WIND tech support had no clue after many calls and tests run at their tech support offices in Toronto. WIND recommended that I get in contact with HTC directly to see if they might have a solution.
One call to HTC started the ball rolling and setup a trouble ticket. Within 3 days and about seven call backs to trouble shoot, HTC had the solution and both of our Maples now have fully functioning GPS with Google Maps.
The problem was in the ROMs that had an old version of Google Maps (both their WM 6.1 and WM 6.5 HTC Maple ROM for WIND accounts).
Solution: using the Maple's browser go to m.google.com/maps and install the latest version. Problem solved!
HTC customer service in North America ROCKS!!!!!!!!!!
Will I buy another HTC product? HELL YA!!!

Here's a gem!
My Snap used to take 30-40 seconds on a cold start to get a location lock (with aGPS turned on).
I installed the attached CAB (which just adds some registry keys, also found here: Here), which makes the phone use Google's aGPS server, and got a cold start GPS lock in 7 seconds... indoors!

Thanks for updating the link.
I have tried both of the CABs for the non Nokia and both make no difference if you
can't get a GPS lock. AGPS simply does not work using the latest Google maps CAB
available.
The "FF Ultimate aGPS Tweak_supl.google_Generic.cab" actually makes Google Maps
take forever to just start up after being installed and still no location is updated
indoors. Also, the phone will not snyc now with the desktop and this is after three
soft resets.
Even worse is the fact the phone now runs slow as hell. Everything takes forever
to open and is VERY sluggish.
Installed the other CAB "FF Google aGPS Settings Generic.cab" and still the same
problems. What could be the problem?
Finally got fed up with the POS CAB and uninstalled it. So far I've notice that the
phone has recovered its speed opening items and the right ones not like before
with that POS CAB which would cause all kinds of problems. Snyc now works
and so this looks like I'm back in business minus the fact I still can't get the aGPS
to work.
Oh well, you can't win them all...

Issue 5715 (GPS), Please star at code.google.com

Yesterday I experienced issue 5715 (just looked it up) pretty badly. http://code.google.com/p/android/issues/detail?id=5715
I switched on my GPS in a city 300 Miles away from where it was last on, then waited for 1 hour with the phone by a window.... No GPS fix. All it sees is one or two satellites. (as seen by 'GPS status').
Later in the evening I had to walk to a new location thats about 0.5 Miles away...No GPS fix in the open! Restarted my phone as I knew this had worked before (many times). Unfortunately it still didnt work. 'GPS Status' showed 3 connected/4 found and a fix 200+ Miles away with a ground speed of 271MPH, Was funny looking at my location (blue dot) flying across the map so fast while I was stationary. (I was standing at the intersection of two streets, no tall buildings or obstructions anywhere)
I finally managed to find the location by just looking at the map.
Later that night I restarted the phone one more time and the GPS is working fine. (6 connected/ 6 found)
Please "star" the issue linked above if you've experienced this too.
If anyone knows if this is fixed with the newer/custom ROMS please let me know.
Thanks.

I had the same problem last year when I flew from Jersey to Oregon. After I arrived, I went to navigate with my Touch HD (Windows Mobile 6.5) and the map put me in Michigan traveling at 600mph. I chocked it up to a flaky custom ROM.
I wonder if theres a common link here, in that its not the software, but in fact the GPS's ephemera data that needs to be purged and/or updated?
Later that day I ran the satellite update software, rebooted a few times, and all was well again.

I'm in Dublin, Ireland and for some reason in both Maps and Google Earth it says I'm somewhere near to Alicante in Spain!!
I installed Secure Wave today and hit the track button on the site and guess what, it said Alicante as well!!
How can it be this wrong guys?
Cheers,
M

+1 for a GPS reset/Clear data app.

I remember the GPS on my N95 thinking I was doing about 200mph when I was in my house before, wonder if it's more a general GPS glitch than the N1's fault.

I had this problem before the update. Haven't seen it since. I'm not saying they are related, I'm just putting it out there.
I did notice a couple of things (that could be unrelated or user error) - 1. if I had a Google Nav or directions course mapped, exited the Maps app and then went back in, my location would sometimes jump from the actual to the cached Nav starting point (make sense?) 2. If I left the GPS widget enabled, I had much better performance in Google Maps (duh! - but I mean no glitches in showing my location).
My pocket theory was it had to do with the assisted GPS portion - the checkbox that says 'use wireless networks - location determined by WiFi and mobile networks'. If any of those networks are reporting a bad location (IP source or Phase 1 location on a mobile tower) - maybe that is what's throwing the maps off? The thing is, the iPhone uses the same location enhancements (Skyhook plug in) and doesn't exhibit the problem, so who knows.

I suspected this, so I turned off the "use wireless networks" option before rebooting. Didn't help, The GPS was still lost.

Are you actually obtaining a lock (solid GPS icon rather than flashing)?

Didn't check that (think it was flashing), however 'Gps Status' reported a "fix" after the first reboot and it was wrong. Showed 3 connected/4 found.
Waited for atleast 15 minutes in the open...freezing.

anyone found a work-a-round or fix for this problem? Trying to use my NBA league pass but says it shows I'm in Espoo ( no idea where it is) instead of in the US.

GPS calibration

I have found that some apps that are location aware or ask me to pick local servers, often suggest servers on the east coast. I am on the west coast of the US. When I am on wifi this does not happen, it is only happening on 3g. When I toggle on wifi is suggests local servers. I have went into location settings and toggled on and off the settings for GPS as well as the "use wireless" option and it does nothing to help the issue.
The maps app as well as navigation work perfectly fine for locating me, this seems to be isolated to apps.

Thats usually an indication your gps is not working. When you use speedtest app with out wifi does it ask you to connect to kansas?

Speed test isn't a good way to find out as it will connect you sometimes to the least busiest server. Gps needs to lock first on a couple sats first time usage after that should be better.
Xda app via atrix

I wad able to get it calibrated correctly. I went outside and calibrated the compass first. I then did a gps lock from maps and then tapped lock again and let it sit for about 2 minutes. Everything is fine as of now.
Sent from my Atrix using XDA App

GPS in Atrix locks the satellite very quick. It could be comparable to a standalone GPS.

[Q] Anyone Elses GPS Aweful?

I have never had my GPS locate me via google maps. My Phone has no issues. Anyone else have GPS issues? any tips? Hopefully a software update fixes it? I have a friend who has the same issue.
[Should have read "awful", not aweful]

Nothing wrong with my gps. Have you upgraded to the latest firmware? Downloaded the A-GPS data (you can get this by using an app called GPS status)? Switch OFF wifi after you do, then leave it to get a full signal lock (takes up to 15minutes or so with a clear view of the sky).

Make sure you are outside with a clear view of sky when you test. It can take any GPS up to 10 minutes to acquire the ephemeris information (satellite position at a certain time) and lock up. You phone cheats this by using the cellular network to provide a general location of where your are and therefore where to look for certain satellites.

thanks so much for the info guys. I had a feeling it had something to do with no cell phone band helping out. thanks!

GPS works fine here, as other have said the closer you are to the sky/window the better.

yeah..give your TF a few minutes to lock up sat positions (if you've never done this)..
this applies to most pure gps devices..cellphones can use cellular network signal to quickly locate your position but the data isn't really from gps itself.

I wonder if it does the wifi cheat like maps for android phones, where it uses the known APs to determine location? I say that because when I first fired up my transformer yesterday, after connecting to wifi, I screwed around on maps and it found me inside my house in less than 30 seconds.

its the reverse for me! in the same room of house i often cannot get a fix on my Optimus 2x. i use GPS Staus app. but i often get fix within 30secs. as a test i have both machines running the app next to each other and the transformer always gets regular fixes.
..... hmm just realised as i type this that i have a phone called optimus and tablet called transformer, and they both run android!!!

I get fixes with no wifi (ie: only GPS) within 30 seconds.

Quite the opposite, mine is extremely accurate. After it gets a fix on maps that little google person is standing right in my front yard in the satellite view! Better than my Droid!

Mine is almost instantaneous. Just tried it at home based on this thread and had a read in probably 5 seconds.

I have not been able to obtain a GPS lock until today when I set my location to use wireless networks. To me this is really stupid because the GPS shouldn't have to use any location settings to obtain a lock in my mind. That is if the GPS chip in the TF is a true GPS chip it should not to rely on a wifi signal to obtain a lock. If the GPS is turned on then it should lock.

I tested sygic gps navigation 11 and signal lock and quality was better than my galaxy s was pretty accurate
Sent from my Transformer TF101 using XDA Premium App

Works fine for me, apart from one minor detail. When I switch from Google Maps to another app, even for a few seconds, then the tablet has to get a lock all over again. There appears to be no way to set the GPS to keep a lock while Google Maps isn't the active program.
That, for me, makes Google Maps near-useless in a moving vehicle. Hopefully other third-party apps won't have this issue.

Google Maps is prety much useless on the Transformer for GPS navigation as a data connection is need. I have heard of people caching a route before hand but ..... Copilot Live 7 is out for android so that is one option. However if the GPS relies on a wifi signal in order to obtain a lock then it is about useless too.

Gps works fine on mine....unlike my icons or Samsung...both returned

gps does use wifi to help gps locate, theres options to turn this off in settings, i went to pick up my dock today and couldn't get a gps lock while in the car with the transformer in my lap(gps status app showed 3 sats but none would lock) just lifting it up 12 inches closer to the windshield made 7 satellites pop up and instantly started getting locks
i think proximity to a window/line of sky is a big factor, and the transformer does have a true gps chip for those who seem to doubt it, also the navigation app keeps running in the background, its better to use that than google maps

No issues with gps here. The bastard finds me every time!

However if the GPS relies on a wifi signal in order to obtain a lock then it is about useless too.

It doesn't rely on WiFi for a lock, it just uses it to allow a faster connection if you don't already have current ephemeris data downloaded. That's a limitation of all GPS receivers -- it takes a fair while to download the ephemeris data if you're out of date or have travelled a significant distance, and without it the device can't get a GPS fix.
You can think of the WiFi location system as analogous to a cellphone being able to use tower locations to help position itself while waiting for GPS ephemeris data.
