A-GPS in android system - Android Q&A, Help & Troubleshooting

I'm about to buy a mobile phone white label that says owning just "A-GPS" (not internal GPS).
If I install a browser like CoPilot or iGO and respective maps on sd card, I can navigate offline?
In other words, my question is whether the system with A-GPS it is possible to browse offline, without spending net traffic, since the browser and maps are on the respective memory card.
Or this system always needs to connect to the network?
Thank you.

Anyone????

It should have GPS, since A -GPS is assisted GPS and only helps the actual GPS get a more accurate reading

Many maps can be downloaded and if they are of your area can be used for location with GPS when you are offline. Navionics charts are an example. Latest googlemaps as well. Experiment with your desires provider. The answer is NO, your system does not always need to be connected to cell network.

Techically AGPS is a method used to get a quicker GPS lock by using wifi/cell approx location. If it only has AGPS they could just be referring to the Google location services part of android which will get your approx position from wifi networks. If it has a real GPS then you could use it offline with any app that has offline maps.

Why not link to a sales page for the phone so people can see some details about it and maybe have a better idea of whether it has gps as well as a-gps?
Officially a-gps uses cell tower information so without more details of the phone you can't get a more specific answer than being told people aren't sure.

I believe it does. Because if you start the program with out any data connection it will exit out. And if you are trying to go on a trip and need directions or are trying to follow the map it wont update unless you have a constant data connection.

Are you using a Custom ROM?
Because I hear that some Custom ROMS have the AGPS feauture disabled. This is what is used for cellular traingulation ( using the towers )
i think i figures it out for now guys....... i didnt know that i had satellite gps on my phone already . i loaded all the appropriate roms from this awsome site!....... so now im just looking fo an easily hackable gps navigator i think ill try tomtom for now but i gotta figure out how to load and register the iso to my pda........ if i like it ill definetly buy it but i want to sure and safe this stuff isnt cheap

It's my understanding that Sprint doesn't use towers to locate position, so you can't use the Mogul to report your location with towers...you would have to use the GPS.
TomTom is working great
Works great with or without cell signal and easy to install and fix.
Is there any GPS program that doesnt require a data connection? Some that have a local Maps database. I have GPS receiver but i dont have a data plan so can't use google maps. Any suggestion? PathAway is one of them but that thing so complicated to use..and expensive

Yes there is. I personally use Tom Tom Navigator 6. This is ONLY the GPS software. I believe the other versions of Tom Tom have the software and a bluetooth GPS receiver in the package ( more expensive ).
You can also use the GARMIN GPS software. I believe it is a little bit cheaper on the price then Tom Tom, but It might lack some features.
I'm sure there are others but those two I believe these are the most known / used.

Actually I find the Garmin has more features than the Tom Tom.
and the latest version of XT has a much better addressing system as far as finding addresses.
I live in a Rural area where roads sometimes have two names because two routes join together....
Tom Tom doesn't recognize one or the other route and will sometimes only take the lesser known route as input instead of the major roadways designation.
Both are great navigators though...I just prefer the garmin.
do you guys know how I set up the GPS after the ROM upgrades? I have tomtom, but it doesn't recognize the internal gps
It was my understanding the location from cell towers doesn't work on 6800 in google maps???
Am I reading this thread correctly that there IS a way to get this to work?

The original version of google maps doesnt use cellular triangulation (towers / agps) the NEW Beta Version does. Also if you don't like Google Maps you can also use Microsoft Live Search.
To get the New Google Maps Beta w/ Cellular Triangulation go here:

If you want Microsoft Live Search Mobile visit:
ls.windowsmobile.com on your cell phone via your designated browser.

Enable Location On instead of 911 on your cell phone first.
You can go to the dialer and press the menu button -- options -- services -- location setting and press GET SETTINGS and enable Location on.
The go to start -- settings -- system -- external gps : make sure that on the programs tap that COM4 is set on the GPS program port menu. On the hardware tab chose NONE as the GPS hardware port menu and for the baud rate choose 4800. Finally on the access tap check the Manage GPS automatically box
All that is to set the GPS to work on GPS software (tom tom, google maps, microsoft live search ......)
Now to the Tom Tom part.
Once Tom Tom is installed and still doesn't get a GPS signal you must then configure the GPS to work with Tom Tom.
Initialize Tom Tom. Go to the Change Preferences Tab ( menu tab that looks like a wrench)
Look for the Show GPS Status Icon ( it is a Satellite ) then click on it.
Once in click on the Configure Tab on the lower left side.
Select the Other NMEA GPS Receiver when you try to select a GPS Receiver : then once selected you will be prompted to change the baud rate ( make sure it is 4800 ). Once you click done you will have a menu stating " GPS is Connected to" and you must choose COM 4:
Now your done.
The bad thing about the GPS in our TITANS / 6800's is that it is not always running and it needs to warm up / initialize first in order to get a signal in any application.
You can either wait until it picks up a signal or download a program to help you initiate the GPS receiver when you want to use Tom Tom.
I'll provide you a program that helps initialize the GPS and then launches Tom Tom for you. ( This saves time trying to warm up the GPS and then looking for the Tom Tom app and running it)
Dont get irritated if Tom Tom doesn't recognize the GPS right away it might take less then a minute when you are in your car or are in sight of the clear sky. Tom Tom doesn't seem to work well in doors.
I hope this helped you out abit.
If you rather choose another GPS warm up / initializing software you can research on your own. Im just supplying you with something that works only with Tom Tom.
Once you download the software extracted in your computer....and copy the software to your device not the SD card - \windows\start menu\programs
This is not a CAB it is an executable.

So if I read this right, you want to use a GPS-like function that doesn't use GPS satellites. You want to use cell towers to do triangulation. Navizon makes a product:

It can provide GPS data output but it does triangulation via cell towers and wifi access points.

Navigation needs WiFi?

Hi mates,
I was wondering all navigation programs on HTC Hero need Wifi or Internet connection?
Because there is a charge using mobile internet....
Is there is a solution via GPS like on HTH Diamond I had Destinator and there is not any charge for using it!
Any ideas?
The only one I am currently aware of that doesn't require a data connection for routing is CoPilot but more are in the pipeline. They do require a large amount of SD card storage space though for their maps.

All "turn by turn" navigation programs use GPS - it is the map "source" that can online. Copilot uses the SD card to hold its maps, so it doesn't need a data connection in order to work.
According to Intrinsycs website, the product you refer to, Destinator, is available for Android though I can find no link to purchase it.

[Q] Why GPS doesn't work without internet?

Hi,
I'm just wondering why my GPS doesn't work without internet connection. It just can't connect to any sattelite. I'm currently using PFGPS v2.0 FIX for my country (Poland) and I don't see any changes. What is wrong?
It requires Internet to load the maps
Can I load maps now to use GPS without internet connection if I'm not in wifi area?

so you have wifi that means you are connected to the internet!!!
for GPS it can only find your position but can't display your location on a map without an internet connection so GPS needs one.
I will wait for answer from another person. Thank you.
There is an application on the market(related to sports/tracking) that allows you to download a portion of a map and then you can use your GPS offline(no data connection). When I get home I will look for it(I have it on my tablet).
Correct me if I am wrong but Brajano95 means that is it possible to load the maps on his wifi connection and keep then saved when he is out and about to allow the gps to connect. You used to be able to do this in the google labs section on google maps but they've since taken it away unless you look for an older version. Otherwise have a look for third party map app on the android market which allows downloading of map data to the phone

Thats exactly what I'm talking about! Now I'm downloading Sygic Aura (about 550 mb) and will test it later.
Because GPS and Maps on CM7 suck balls at best. Maps is using your I.P. for the GPS coordinates when on WIFI, without it Maps is counting on a reliable signal from your GPS; and that's just not going to happen with CM7.

I know a fair bit about the GPS module in the Ace so i will comment. I think someone has already told you that it is possible to operate the Ace with preloaded maps. Likewise, i thought that the OP's choice of Sygic Navigation is a fair one.
Back to the original question in the title. GPS can operate with or without internet be it wifi or data e.g. 3G/2G. The difference is how fast you can obtain a GPS lock. Without using any positioning help from data connectivity, you are looking at a lock time of possibly 15 minutes thereabout.
There are 4 modes of operation possible for the GPS module in the Ace which is actually Qualcomm's GpsONE.
1.) Standalone (Slowest using positioning information in cache and smart polling)
2.) MS-Based (Sends data to nearby cell tower(s) and makes use of GPS transceivers in the cell tower(s)
3.) MS-Assisted (Similar to MS-Based BUT data connectivity is broken when GPS transceiver is online. I don't quite like that!)
4.) MS-Based/Hybrid (You need to have superb data connectivity probably cell tower signal strength should be in the -50dBm region. Not very useful in real life usage)
i have had my own thread for fixing GPS, so read up if you want to know more here.

first you need the maps to use it offline, and the correct gps.conf for your location http://forum.xda-developers.com/showthread.php?t=1284506, then you can use it without internet
Mapdroyd is a great app that allows you to download maps for offline use. Unfortunately there isn't offline navigation though..
Hi,
I've solved my problem, just install Sygic! Thanks for helping guys
btw u dont need too install anything.. go to google labs inside maps and add map cache.. now long press a location on map.. click the arrow on the address and u ll see an option to cache that area.. the steps may not be accurate as i tried it a long time back and dont have my phone with me but its possible and what u have to do will be more or less the same...

[Q] Question in regards to using the GPS dongle for navigation

Ok so I have a question. I got my GPS dongle yesterday (it works great!) however When I try to use it with google maps for navigation without wifi, maps says it needs a data connection to work. I'm not sure how some people here are using the TFP with the dongle for navigation without wifi. Can someone enlighten me?
gps needs data
The issue is that google maps and navigation needs to download maps and data. What you need is a navigation app with offline maps. For mapping try mapdroyd.
There are two sorts of GPS navigation apps - the sort that plan your road journey from A to B and give you turn by turn directions and the sort that display a map, show where you are and you can put in a "as the crow flies" route A to B to C which is for walking, sailing or flying
(there are many free maps for these apps and your country is relevant - available file formats . Suggest you google free gps maps + country )
I'd search for "gps map" in Google Play and see what catches the eye.

Google Maps allows for offline maps, just enable it in the LABS menu item.
Google Maps uses data to download the maps. You have to use a Navigation app that doesn't use data connection.
I personally use CoPilot Live Premium USA. Well worth the $20 w/ Live Traffic. The Maps are downloaded to your SD Card. For my region (So CAL) it was about 764mb. Once again, this app allows you to use your Primes GPS connection and no data required for operating.
There are plenty more Nav apps in the Market store...it's up to you which one is of your liking.

I agree. CoPilot Live is the best. I've gone thru all the different ones in Google Play, and none could beat CoPilot live.

The trick is to set the navigation destination while you have data service and let it start and make that blue route line. It will track all the way to the location, and if you cached the map area (settings > labs) even reroute if you go the wrong way, all without the initial data service.
Each pre-cached area is 10 square miles and is stored unless you wipe the cache. I'm in lower NY state so I just did my house, upper NJ, and NYC and it covers most all of the places I ever go without ever having to think about it again.
Going somewhere new just cache the route and location it will be there if you ever go back. Still better than having to pay for navigation in my book.

That' exactly what I did to one of my GPS dongle videos. I used Google maps for navigation by using my Evo as data connection then cut it once it grabed the directions. Works without any problems.

School me on the GPS and Google location services

So I've had my phone for a year and rarely use the GPS feature.
In the past (stock) I've kept all my phone features on including Google location services, etc. Now that my phone is rooted and running AOKP, I turn off all the Google location services, report my location, etc, to save on battery.
My question is since this phone uses A-GPS (yes I wiki'd it) does it mean that it is REQUIRED to have these location services turned on in everywhere in the phone in order for GPS to work? I've tried using GPS without all these services but for some reason GPS didn't seem to work. It comes back with can't determine location, etc.
So do I need all these Google services to be running or should I just be able to enable GPS and have it work for turn by turn navi?
Should only have to have GPS turned on.

AFAIK agps just helps it obtain a lock faster.
Sent from my SGH-I777 using xda app-developers app
aGPS supplies the GPS the updated almanac and ephemeris data from the network, and allows faster lock by aligning the system clock using one of the clock servers.
If it sounds like Chinese - then google all the unknown terms, and eventually you'll be able to google the answer to your question.
I read some other article that stated you needed to have data turned on as it draws the maps. All the google maps are not stored to the device???

So what does "make available offline" in the maps settings do? I guess I just can't turn on GPS and enable "offline maps" mode and that will work too.
This is why I ask these questions. Some people say you don't need anything other than GPS and other say you need to have location services on.

Enabling offline maps tells the device to cache any routes you plot in nav or maps so that if you lose data connection navigation will continue to function. If you depart from that route without data connection, you'll lose nav.

1. If you just want to use the GPS feature, then it must be TURNED ON. That's it. No other requirement, other apps asking for location services have nothing to do with GPS function of the phone.
2. About google maps and gps service on this phone.
a. the map itself is stored on their Google server, so in order to use map, you must have accessed internet, hence either wifi or mobil data required.
b. if you carry other maps that stored locally in the phone internal space such Tomtom, Sygic, .... you DO NOT need wifi or mobil data to use this function.
3. About the Google's OFFline maps. A lot of people do not fully understand the usage of it.
Back to step 2a above, I said "google maps stored on their server" so you need internet access. In this case, offline map is just a small cache (10 miles radius) and it does store in the phone memory. So yes, you do NOT need internet (wifi or mobil data) to use "offline maps" (of course, you must create one before hand)
What is the down side?
a. As mention, it is just a small cache.
b. If you define the term "GPS" as global position system then you know all it does is getting lock and determine your location and that's pretty much is. You CANNOT route the route. You CANNOT navigate from point A to point B. You CANNOT search for an address.
