Is this function in our Kaiser? I've enable it from the Kaiser Tweak but today i tested it when i was in a tunnel....it did not work at all and the tunnel was 4 KM long....it should have had enough time to get a fix if it was working.
Is the Assisted GPS what i think it is?
How do you expect to get a GPS fix in a tunnel???
AGPS is basically what the QuickGPS app. does: it downloads sat. data (satellite locations) via a network connection from a server, so that TTF (time to fix) is reduced, since the device doesn´t have to download above data from the satellites themselves - which is slow....
Hope I was not too unclear, doing a search will give you much more and detailed info about how GPS works......and it doesn´t in tunnles....
As mentioned above, the AGPS uses server information (via cellular network) to locate the GPS satellite for a quicker fix and hash conditions. For a 4KM tunnel, I'm sure that your phone would have lost both GPS and network signal.

Thats correct, there are som applications that tries to estimate where in the tunnel you are when the fix is gone. But I suppose this is a function of the application and not the GPS hardware
I stand partially corrected........ http://en.wikipedia.org/wiki/Assisted_GPS

Which is why the title is "Assisted GPS".....I've done some search on AGPS and it's suppose to use the cellular to still get a fix when in the tunnel. Well....i read it sometime ago way before Kaiser was out and this was actually one of it's talked about feature in Kaiser. Using the Kaiser Tweak, one can enable this feature but i've tested it today in the tunnel with strong cellular signal, the GPS is dead until i came out of the tunnel.
I guess it also has to be supported by the particular program. Many TomTom PNAs have a dead reckoning mode which shows your position in a tunnel based on your "entry" speed for about 30 seconds, than the position freezes in the tunnel. Now that of course has nothing to do with AGPS, but it´s a way of overcoming temporary signal loss.
Best way would be to have an inertial sensor built into the phone like in fix-mounted car-navs......but then again, that would be overkill....
You have to remember that the Assisted GPS (Cellular network mode) relies on the fact the network itself supports the feature. I know most in the UK don't have it turned on in general use. They only allow it to be used by emergency services and the likes.
Perhaps that's the same in your country?

Probably so.....oh well....it was worth a try
Thanks guys for the input.
I have two questions really..
I live in the Netherlands and have an always-on internet subscription... but when I travel abroad I want to do the following:
1) Turn off all data transfer so I don't get charged for things that want to update or whatever
2) Keep the GPS functioning
Using the connections manager, I turned the data connection off, but this didn't work at all. It would just connect through the phone line anyway. I resorted to deleting all the internet settings from the phone which was a difficult, lengthy and frustrating process, and I ahd to put them all back in when I got home.
Also, after I did that, GPS did not work anymore. I could not find a setting anywhere to turn on or off the GPS by itself... is it linked to the data connection? I couldn't actually turn the data connection on in the connection manager when I deleted the settings... I couldn't access the GPS at all from any program unless I had the data connection on, and working. Is that right, and... isn't that weird?
Yes, it's weird. I faced same problem. Solutions?
To totally prevent data connections, you have 2 choices:
1- remove GPRS/3G configuration from provider
or
2- nodata! That's what I use
About the GPS not working while in fligh mode, I turn on bluetooth and then GPs works
or alternatively rename the access point name...
e.g. mine is "orangeinternet" I stick a character in front "xorangeinternet" and thus it fails to connect if you do accidently start up an app that tries to connect.
I know it works for Orange - cant confirm it with other providers but I suspect it will be the same.
Can anyone else on other provider networks confirm?
nodata is quite handy
Nice, I'll try nodata!
The GPS eludes me though.
Use "Advanced Config 3.2" Available on this site.
Menu->More Settings->Connections
You can disable each network connection. does not affect GPS
To use solely the GPS you need to install a specific GPS enabled stand alone software on your phone, such as TomTom or IGO.
Otherwise you will be using a AGPS data connexion which is expensive abroad.

actually it does... tomtom7 doesn't work if you're in flight mode (no problem with igo8 thou).
Hi,
I use iGo8 and TomTom 7 and with both of these applications, everytime I close them I can see that they openend the GPRS connection (internet mobile)... my internet has no limit of use so it's not much of a money issue but the battery is going down pretty fast beacause of this background running data connection ...
Is there something I could do ?
Install nodata.cab from modaco

Thanks for the reply. I tested the software you pointed out. It's a solution except that its pretty boaring to have to lock the internet connection everytime you need to use the GPS (for it's 15 to 20 times a day with a new adress) ...
Any idea on how to disable the connection only for the GPS software ?
EDIT : even with all connections disabled with nodata, the gsp still manages to open the connection !
I had exactly the same problem. I tried the same cab as you and it didn't work... I tired creating a bogus connection and selected it to try and stop the GPRS connection as someone else advised but a GPRS connection kept on opening itself...
Do what I did and flash a stock HTC ROM over your SFR one... It completely solved the problem for me.
You might want to dump the old SFR one first for guarantee reasons.
I use igo8 and it never turns on the GPRS connection.
I don't know if this is the cause, but can you check if assist GPS is ON or OFF?
Mine is OFF which is the default behavior...
If you don't have it, you'll need an app like "Advanced Config" in order to be able to see and change the A-GPS behavior
--Double post--- Ignore
This was the problem ideed. I have direct access to the A-GPS ON/OFF option in the parameters and it was ON. Switched it to OFF and the navigation software don't start the data connection now !
Thanks !
With data from network I can identify the location instantly. However, if I uncheck "Use wireless network", I have never located myself on Googles Maps. Is it a defect on the GPS?
Thanks in advance!
Google maps doesn't includes world map installed, it only store some caches.. you still need network to download map data & network based location, GPS is used for more accurate result & yes it's true p970 gps is not so good.

Thanks for your help! In fact, I already have cache of Google Maps, then turn off the wireless connection, to figure out the performance of the GPS alone. It sucks!
BTW, I used HTC Touch before and its GPS could identify the location very quickly.
have you test with the GPS fix (in hidden menu) ?
Actually you are wrong, GPS in very good in OB.
I used it for a trip of 700 KM and it has difficulty only the first time when it aquires a position (this is normal if you don't use AGPS) like 3-4 minutes...
On the road I turned off GPS by simply locking the screen (IGO8), and on relaunch the GPS position will not take more than 30 seconds. I don't have any data on my contract so it was purely GPS!
The first time it's normal to take a very long time because a large number of sattelites have to be aquired to for pin-point accuracy. Afterword I think it works with 2-3 visible sattelites!
My previous phone was a HTC Diamond, and it was exactly the same if I dind't used the GPS app every day that downloaded sattelites in advance.
It works but it's slow (as it should be). For me it's around 1 minute in hidden menu. Best place for testing outside hidden menu is Compass app (If you don't have data connection for maps)
For hidden menu:
1. Go into the LG hidden menu (3845#*970#)
2. Go into GPS Test
Test it (you need activated GPS of course)
if it's really slow, try this (I think it's if you use network to pinpoint but everyone is suggesting it, so I will too)
1. Go into System Settings
2. SULP Setting -> SLP Server Setting
create new:
Nokia (slp address: supl.nokia.com, port: 7275, no cert and no TLS setting)
If it still doesn't work, try other variants (LGE SUPL, Spirent, etc).
Thanks everyone!
It works now! The. GPS is quite sensitive!
Sent from my LG-P970 using XDA App
In the gps test in the hidden menu, there's not such option as gps fix.
Me too, I'm interested in using my gps without the assistance of the network cells. I've already tried the three supl servers and it doesn't seems to work for me. So, if someone knows how to use it without network assistance I'll be really grateful.
Thanks in advance.
It should work out of the box.. afaik, you don't need to mess with the SLP servers unless you are using some sort of assisted GPS mode (with wifi or 3g connection). I'm using it straight out of the box (after installing the fresh firmware) and it works normal in the car (1-2 minutes first fix, a couple of seconds for any other subsequent fix). Getting a first fix while on foot does take a bit longer, but that's true with all the other non-android devices I've had. the OB has normal (no more, no less) sensitivity when it comes to GPS.
i think there it`s a problem in OB mine has problems with gps too , and already o try`d all kind of apps and even use the gps standalone from the fresh new update soft and nothing , fix the gps for the first time and after then i can`t travel with standalone gps
Hi, Just got my Galaxy Note a few weeks ago. Downloaded this GPS app called Sygic and was wondering will it requires data and blow up my phone bill? I do in fact have a 500MB internet data plan but i usually used it only on internet. Pls help
GPS wont use your Data connection, i think sygic has pre-loaded maps. if so then it wont use your data connection.
Hold power button for a second or two, select disable data, turn off wifi.
If Sygic continues to work, you are good.
What size is the app? Does it have on-board maps? If the app is like 6mb and there are no additional downloads, chances are it streams data to download maps on the fly, hence using your data. If the app has an initial download of a gig or so, you probably have onboard maps.
its a 6mb file. But when downloading the maps. Its about 300MB.
GPS uses very few data to approximate the position (that helps to fix) and download ephemeris (essential to fix). I've tried my GPS without data, fix time goes from few seconds to more than 5 minutes (it did not achieve fix).
BUT, I think a 500 Mb plan is far enough. I use from time to time Google navigation (which download maps), and use 200-300 Mb a month (not only with navigation).
GPS not using data, it connects directly with satellite, but when you use any application that uploads your location, uses data. e.g. Google map lattitude. to locate your position data not being used, but lattitude updates your location at define period of time, that uses data.
Sygic, it dont requires data. but on first usage it download required basic files n map, that uses data. Sygic requires basic files of around 300Mb or more. as well Map as per your selection. e.g. India map + Basic files are about 800MB, so if you have not downloaded it with wi-fi OR transfere these files (it stored in 'Aura' folder of device internal memory), then it will download. Once you complete this dowload, you can use it without data /even without SIM card too.
Google Map navigation, That uses data. but you can limit data by pre fetch map, You will get this option in - Map -setting -Labs - enable precatch map area
Now you can long press any area on map, you want to travel - press popup menu - select pre cache map area, it will download 10ml area, you have selected. so this can be fetched using wi-fi. and you ca save data during navigation. But it still requires active data connection to run Navigation.
Nobody's There said:

Ya, you have to download maps first time.
Thanks everyone, Now i need to figure out whats making my phone bill burst as hell. xD
Use "Track your 3g" app.

This is untrue. First, on my captivate when I still had a 200mb plan, before I switched to unlimited, I would input my destination over wifi, disable mobile data, and I could get Navigation all the way to my destination. I have done the same think with my WiFi only transformer. You only need data at the beginning of the trip, unless you get a fair bit off course.

I said it requires to 'run' navigation.better term is 'Start'. you have already run application when you wr on wifi, But what about if you have to restart it in any case? In sort it is not complete offline, like sygic / navigon n other offline mavigation SW.
Onboard navigation programs like Aura Sygic do not recquire data connection..
However after installing Aura, you will need to download the maps of your choice and in this case you will need wifi connection and you will do this only once, unless you want to download more maps in the future..
With Offboard navigation apps like some versions of google maps, the required maps are not installed on your device, but in a server and therefore you will be needing data connection.
I will always go for ONBOARD gps programs, they are more reliable, stable and I wont get a data plan only to use Google's supposedly free stuff which are not working that good anyway. Not to mention the roaming costs once I am abroad....so, not that free...
My favorite onboard program is iGO, but unfortunately, I cannot find a suitable version for the GNote's screen resolution...
But Aura Sygic is doing just fine, at least here in Europe..

If you want to download gps ASSIST data, in order to speed up that first satellite fix, you can do it on demand by using apps such as GPS Status and you can do it at home using a wifi connection.
But since I have this monster (GNote) The first fix happen always amazingly fast even during a cold start without any assist, unlike many other phones I owned
So when I use the gps, I am always offline, I dont have a data -account, data network mode is always deactivated and I dont have any APN configured
And off course I dont have wifi in my car
