Hi,
Im on darky 9.3 and very happy with the rom but Ive massive gps issues...
It takes about 5min to fix, sometimes more, as soon as Im start to move (car, feet) the signal stops at the last point...
In copilot Im gettin only 6 sat and no one is about the half...
One you have a custom rom ask the developer search in his pages read the faqs .
Two millions of posts on here about GPS use search and try the fixes posted .

I recommend you try docs rom based on JP8 and the Q1 modem. My GPS is great now.
On some units, the precision of GPS is poor and often can't be fixed enough by software. Only 2 solutions:
- RMA for a new built unit
- make the hardware antena fix suggested in this forum (search here for the fix)
On bad units, despite all firmware/software hacks, precision is bad. It will be ok in rural areas but will jump streets in urban areas with high roads density.
Probably, the soldering on antenna varies from unit to unit on early models, explaining why for some it's ok and others not. Also, many live and try GPS in areas with lower roads density, giving them the impression of a good track despite a bad precision of the GPS. Also, tons of posts with only test of the fix speed. The fix speed was solved enough on some ROMs, but the precision will never be enough on high density urban areas
Well assuming that its not hardware I would try a different modem. I was on darkys rom and had a very bad GPS with the JQ1 modem but JVE works very well for me.
I suggest you try a couple different ones, you can get CWM flashable zip files from this nice person here: http://perka.zapto.org/
the galaxy s has always had poor gps but samsung will not fix it

Recent tests on cold boot ie fresh rom installed .
Clear line of sight to sky 5 mins to allow new satellite data to be picked up no wifi no mobile date pure GPS no APGPS etc .
Modem JPY 10 satellites found error 5-10 metres
Modem JVK 11 satellites found error 5-10 metres.
Both on Rom Kitchen XWJS8 with Hardcore kernel .

The problem is that GPS is more complicated than that.. Just because it says "5-10 accuracy", how do you know that's true? You need tracks to work that stuff out.
Originally, there were a few people here who grabbed GPS status and pointed out their "GPS was perfect". But, after pressuring them for ages, they either admitted that their tracks were horrible (but found excuses), or disappeared. There was one guy though who I saw with a decent track, but I suspect he might have used a bluetooth GPS (I have never seen his results replicated)..
Test using tracks, preferably using a second GPS as reference (such as a fitness GPS). Number of satelites and claimed accuracy means very little, because satellites move around. How do you know if there were maybe a maximum of 11 the first time, and not 16 the second? Hence why you need a reference.. So you can compare the tracks accurately.
As you have said before .
Post was really only a reference .
My GPS does what i want tracks i return are good enough for my use as is location etc .
My tracks have been posted before in the GPS thread .
Next time i use tracks i might remember to post them . But you ignored the last ones i posted .

I played last night a little bit around with my gps because i had the same problem.
I found a code to get in the gps service menu *#*#3214789650#*#*.
I found the SUPL/CP Settings and there is the supl.google.com server, i remembered i had some gps problems on my Nokia E71 too, long time ago.
On my Nokia i fixed it easily with the supl.nokia.com server, and i changed from google to the nokia server and now i get the gps fix in a few seconds.
I tested it about 6 times, always deleted the gps cache, works for me.
Maybe you can test it and give a reply, you dont need to reboot your phone, it works immediately.

Ohh, i understand.
For me, the first Gingerbread modem (JVE) solved all my GPS problems. I even compared it with my Garmin Nuvi and they had same precision and speed/refresh rate, the only difference is that the Galaxy needed 2 or 3 min without data connection to lock satellites, while the Garmin only needed 30 secs. I can't complain
Does the Tablet Really Require the Wifi to be On to use it? Only way we can get it to work is if we turn the Wifi on and then it uses AGPS.
Downloaded GPS Status and it sorta seems to confirm this. Ive read other sites of people returning the product and getting another and GPS works outta the box w/o Wifi?
Thoughts? Solutions?
--Solved -- Issue seems defective Equipment. GPS works Fine in Airplane Mode with GPS on. Tablet was returned for another and now works.
Haven't checked this, but it seems a bit silly. Why would you need a (static) wifi connection when u use the GPS (for moving around). Doesn't make any sense. I will test this tonight.

With the one we have here I can Confirm the only way i can get it to work is with WiFi on. And Acer Support confirms this..
But there is so much conflicting information out there that Id like to see if it can get cleared up.
If people are returning them and their new ones are working fine with normal GPS then did ACER have a Bad Lot? Or are these folks just making rumors.
I've just quickly checked this with Chartcross GPS Test. With WIFI on I could see one satellite indoors. I switched off WIFI and then saw four satelites, so it would seem that WIFI does not have to be switched on for GPS to work. However, having a data connection is always a good thing to get AGPS data with.

From my experiance, no it doesn't . I have been using mine with the wifi off with no problems. I use Copilot Live USA to get around all day at work. One thing is, is that Copilot freezes on me if I try to go into the settings menues.
Acer Says Yes
I chatted with an Acer rep this morning and was informed WIFI or 3G is designed to work with the GPS. GPS will not work if there is no data signal. Being hardheaded I called hoping to find someone with more knowledge on this matter and was told the exact same thing, NO WIFI/3G = NO GPS. With this set back I have decided to return.
But I am curious why some peoples are working and others are not?
Im sure my Buddy will post here soon.
but he called Acer and they are saying that it requires Wifi for GPS by Design.
So if everyone else is able to do it.. and he isnt and Acer says thats the way it should be..
Then either some folks have an "added' feature design flaw or they are Fibbing about it. Or Acer just dont know what they are talking about and my buddy has a defective one.
I do not seem to need to be connected to Wifi for GPS to work. I did notice something interesting while researching this though. 22% of my battery usage was coming from cellular. Thats a huge amount of power being used up to poll for a cellular signal that a wifi device isn't doing anything with.
I added about two hours to my battery life by turning the tablet on Airplane mode and then enabled Wifi. Thankfully the little airplane icon in the status bar is only there for a few seconds
The issue is not GPS need WiFi. It is the map need WiFi or 3G datalink in order to be updated with the GPS signal. Your tablet does not preloaded a map like a portable Garmin or TomTom GPS device does.
The GPS does not require Wifi to work, however if you are using an app like Google Maps, this app DEPENDS on wifi to download map and pois. Google Maps is not like your GPS software on your TomTom or Garmin GPS, it downloads the data using the cell modem or in this case the wifi on the device.
To summarize, if you use an app like Copilot or another GPS app that has maps predownloaded then the GPS works just fine on it's own without Wifi.
I hope this clears it up.

Then Why Doesn't Foursquare, Gowalla, Or even the GPS Icon Activate.. Or Even using GPS Status.. Using GPS Status It wont do anything unless WiFi is on.
Totally Understand that you need wifi For Map Downloading. But when you have a Static Predownloaded Map using like MapDroid or Even TomTom Software the Maps are preloaded nothing to download.
So you all Are SERIOUSLY saying that your GPS works Fine with out WiFi I ask you to download GPS Status and Try it with out Wifi Being on and See if you can get your GPS to come on and get a Lock.
Because Acer Support has already said that the GPS is WiFi dependent.

Ok, this is what I did. Turned off wifi and ran GPS status. It locked on to 3 of 6 sat so I guess it works. With wifi on it seems to locate more sat and locks on quickee.
Just to make sure in settings you do have GPS on under location and security correct?

I tried using MapDroyd with all preloaded maps, it would not give me a Red X for location until I flipped on wifi. That was the only reason I contacted tech support and both chat and phone told me the same thing. There is no power to the GPS until 3G/WIFI is active. Sounds stupid I know, I like the tablet and what nothing more than to keep it but I just refuse to keep something that is configured in such a way. I can live with the AdHoc issue since I know that can eventually be resolved.

Trust me I was very clear that I had maps pre-downloaded and the person on the phone was very clear what they told me about how the hardware was configured.

Not sure I believe what they said.
I just did one more test. I turned wifi off. Reset my tablet. Made sure wifi was still off. Opened up GPS Statues and it locked on to 5 of 7 sat in less than a min indoors. I dont have any nav software with maps so I can't test that. If GPS status shows nothing with wifi off for you I'd exchange it for a new one.

None of those programs work without a data connection. Once you use a program that works without requiring some sort of data, the GPS will work.
I don't really care what Acer says - if you call acer and ask 10 people the same question, there's a possibility you'll get several different answers.
I know what I've experienced, and that is that the gps works with wifi disabled.
I'm confused on what you're debating exactly though, are you saying that the gps does not activate/work without wifi or that it doesn't lock on to satellites?
If you want a simpler test to see if it works/activates simply refresh your weather widget manually and with no wifi connection - you'll see the gps icon pop up and it will say searching for satellites. It won't work, since the weather can't update without data but you'll see that it activates the gps.
In essence, the gps in the A500 works exactly like our cell gps, there's no difference. It's Assisted GPS (aGPS) and requires a data connection to locate the satellites quickly vs. standalone or autonomous GPS found in our Garmin/Tom Tom/etc. Without data it's going to take you 10m-20m to find a lock, with data, 3-5m. This might be what's messing with people. The good thing is if you lock on when you get into your vehicle with help from your wifi for example, then you won't have to wait for it to lock on at some other point. Since my gps is on in the tablet all the time, it's locked in and I suppose that's why I'm not having a problem in my tests.
Another thing to keep in mind is that the GPS in use on these devices uses aGPS (assisted GPS) - which uses a combination of cell tower info (if using 3G) and/or known WiFi hotspot locations to help nail down the starting location and speed up the discovery of satellites.
Y'know, the stuff that Apple & Google are getting in so much trouble for having recently

Ok I am back home after going to BestBuy and picking up a replacement Acer A500. This one grabs my current location using current setup.
Airplane Mode On
WIFI Off
GPS On
I will be going in to the city tomorrow and run a few more tests, will post a new update after but this is looking promising. Thanks again for the feedback!
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!

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.
Hi Guys,
Lucky me, I've got 2 devices as gift from 2 different persons on an occasion. One being Tab 7.7" and the other being Tab 7 Plus
Obviously I love the 7.7 for the brilliant screen. I thought I will use one of the 2 devices in my car just for navigation but just to my shock I've found that the GPS lock is taking longer when compared to other devices (Okay, My wife has a iPad and an iPhone) ....
As far as difference in time to lock in to the satillites like the Tab 7.7 sometime take more than 5 mins (Once it took close to 10 mins) even while I am in a road with clear sky but the Tab 7+ is a bit faster may be 2 - 5 mins for the same which is still longer than acceptable.
Edit: SIM card on.
Car Navigation Application : Sygic (Singapore & Malaysia)
This application is a charm and it work beautifully on my HTC Desire HD (<5 sec for lock) and iPhone 4 (2 - 5 secs) even on a cold start. So it surely is not an issue with the version of the app in android but the problem with the device.
I am still very happy with the tab 7.7 after all what more can I ask for something that I've got for free but just curious about others experience as it could be a HW issue for me.
Let Us all share our GPS experience here wrt issues and accuracy (both good and bad) with which we can create an repository of information for others to refer with.
I have noticed that my GPS won't lock on unless I have a sim card or when I was thetering to my Samsung galaxy s phone. Also noticed that it is not really accurate its off by quite a bit. Any suggestions on how to get it to be as accurate as possible.
Sent from my GT-P6800 using xda premium
I got the same problem, on my p1000 i can get a lock for 2-5 secs using copilot, i used the same on my 7.7 and it takes forever to lock..
Another this, using this as a gps device might not be a good idea, it could cause burn in issues that AMOLEDS suffers from.
Just my two cents
when i bought my 7.7 tab it has no sim in it for about a week but the GPS locks very quickly (i precacached google maps and used it as GPS device when driving), initial lock takes about <1min while succeding GPS locks <10secs, as far as the specs indicate it has the same GLONASS GPS capability as the GNote
On android, I'm pretty sure GPS is useless without a data connection. My 7.7 takes a few seconds to lock on at the most, using a sim card. Even locks on inside buildings. When I took the simcard out once, it then took forever to lock on..
Sent from my GT-P6800 using xda premium
I can confirm that my 7.7 takes only a few seconds to lock on with sim inside. Haven't tried without it yet.
Just tried mine for the first time. Enabled satellite + Wifi location tracking. Locked on within a few seconds.
I am in Muscat, Oman and Wifi isn't as eponymous as in US cities.
Edit: Just to be clear, I have a sim card with an active data plan in the device.
I got problem, on my p1000 i can get a lock for 5-10 secs using copilot, i used the same on my 7.7 and it takes forever to lock..
Guess it suffer the same problem as asus transformer prime. because of the metalic back it cause the GPS to suffer.
can anyone try GPS track program? see how many GPS satellites being lock ?
Mine locked within 10 sec for the first time while riding in a cab (it was down to 5m accuracy)
How can we increase accuracy?

When I used my GPS in Germany and France my data roaming was DISABLED, so I guess it only used GPS to lock on within the 10 seconds that it did so?
I have noticed that the GPS only works if you have some form of data on the tab ( either sim or wifi ) if not the GPS will not lock on and it says "data connection lost", why would this be? Is this normal or a bug?

The tab's GPS unit probably requires AGPS data, which is downloaded from the internet. Some GPS units don't require the data but I assume this one does.

Ahhh OK, thanks for the info. Actually then how do the wifi only version work? Guessing by what you mentioned it does not require AGPS
Sent from my GT-P6800 using xda premium
The Wifi only version would use AGPS as well. Basically AGPS is assisted GPS. It uses cell towers (for 3g models) and/ or wifi hot spots to provide location data, hence assisting the GPS unit in your phone or tablet. Try removing your sim from your phone and switching off wifi, the same thing will happen. It will take awhile to lock.
I have a galaxy S, which is notorious for poor GPS reception. I use a bluetooth GPS unit (check out apps in the market) with my phone, and it works a treat.
Mine 2-5 seconds with SIM and using fasterfix for my region (China) -- accuracy is TIGHT (5m)

Hi Mate,
Can you let me know the Bluetooth GPS device name/price so that I can give a little life to my Galaxy S I9000 ?
My N1's GPS refuses to lock. Using GPS Status, it shows 7 sats, and won't catch on any. I stood outside for nearly 10 minutes and didn't get a lock. My Galaxy tab locked instantly (with 13 sats). Radio is 5.12.
Any ideas?
When I have this, I open Google Maps and then it does get a lock. If I open GPS Status after getting a lock in Maps, then it locks in GPS Status too.
You might want to reset and download new A-GPS data too (preferably when connected to a WiFi network) .

Issue is I was trying to get it to work with Cerberus.
PS. side note (don't hate me for asking), how on earth did you get a 100+ mbps download from your cell?
I always manage to get a lock with Maps, all other apps work thereafter..
Download speed isn't on my cell, but on my laptop When measuring it on my cell (WiFi connected) it doesn't go above 25Mb/s.. And my cellular network speed is capped at 3.6Mb/s.

Tried using Maps as well to lock on. Still no go. Different ROM make a difference? I'm running Hypersense on it.
Ah, you might want to change gps.conf to your region (North-America I presume). It's set to Europe (NTP_SERVER=eu.pool.org).
Edit: backup the original gps.conf (rename gps.conf.bak or something) and put this one (right click > save as..) in place e.g. with Root Explorer. It's located in \system\etc\gps.conf.

Or use fasterfix, free on market.
So I used fasterfix, and set to Europe (which is where I'm visiting with it, bought the phone for this trip). I got it to lock on while on WiFi. But when I tried again today, it wouldn't lock again. Hmm....
I had a very similar issue with Hypersense Nova. I had extremely slow or nonexistent GPS locks on it - even with the Fasterfix region change. However, with stock ROMs, CM7, and now BCM/TexasIce its never had a problem.
So unfortunately, from my observation, there appears to be an issue with the HyperSense Nova port for the GPS (perhaps only outside of North America though).

My mistake. If the original GPS.conf region is Europe then my supposition is erroneous. I changed mine to Oceania, by the way.
It's a shame GPS that can be flakey in general - having to troubleshoot cloud cover, building interference, even steep hillsides blocking the view to the sky... I don't think the Nexus One has a great GPS receiver either.

Never really had any major issued with GPS on the Nexus One to be honest. In comparison, I've read some GPS horror stories about other Android phones. Can't remember exact ones, but I'm happy that my N1 GPS works!
