Google Maps

hey guys, i am using the stock google maps on the phone. I take it that the "gps" it is using is free of charge because it is not using my data connection, what does use data is to load the map. Everything works well untill I enter a part of the map not loaded. Is it possible to have the map preloaded so that it doesn't need internet to view it?

No google maps works off of data, gps is independent- like you said.

GPS works like this (simplified): The satellites are all constantly broadcasting their ID number and the current time (from very precise clocks onboard). The receiver picks up the signals from several satellites. Because the different signals all had to travel different distances from satellite to receiver, the times in the signals are slightly different. From this difference, and from knowledge of the exact orbits of each satellite, the receiver can figure out its own position.
No data transfer needed, and also, btw, nothing transmitted from your phone.

Google navigation on evo does not require sprint data?

can we get that ported?
just checking out this review of the evo

although i think gps+data is better, when i travel i don't usually have 3g so using gps only would be beneficial to me.
what do you guys think? is this guy full of it?

My guess is he doesn't know what he's talking about, or he misspoke. Unless there's about a gig worth of google maps data stored somewhere on the device, it absolutely needs a data connection to get the map data on the fly.

Wow this sounds great!

you need a data connection, either through wifi or 3g (or really slow through edge) to get the map, or the route if you are using navigation. the gps does not need data to put you on the map.
if using navigation, the map data is cached, and the gps tracks you through the path. i can load the path at home, on my connection, or in decent 3g, and then my navigation is maintained through dead zones, because of the cache. my buddy lives in total wasteland, and i drove out there a few weeks ago, with no loss of navigation at all. i had no phone signal for half of the trip

[Q] pls answer. tq

Hi, I Live in malaysia. Was wondering is there any GPS Navigation app in the market that doesnt requires a mobile internet or WIFI while on the road? Thanks

Sygic aura, that having malasia coverage
Others are navigon, ndrive but i dont know these having malasiya coverage

Dude or dudette..get your data plan..no meaning having such smartphone without the data plan ;P

Im Using a unlocked one. dont rely on data plans that much

ya, sygic aura wont need data plan once you install n download map.
and as per my experience Sygic is best among other i have used e.g. MapMyindia, Ndrive, Navigon

use wifi to cache over all the data in google maps and then u can use it offline

Though it requires active data connection. Try it by data off n wifi off, it will say 'data connection lost'
It just helping to reduce data consumption

[Q] Does GPS uses data?

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.

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

[Q] Bluetooth GPS and Galaxy Tab 2 7"

Hi Everyone.
Does anyone tried to use external bluetooth GPS reciever with Galxy Tab 2 7" (P3110) with Bluetooth GPS App from Android market?
Also, do I need root for this app to run?
Marek.

Why use an external GPS when it has GPS built in?

As far as I know it has A-GPS.
Or maybe I'm wrong...

A-GPS is better than GPS. It means GPS plus the ability to lock on quicker using Wifi and cell tower positioning.

"Reliability: Location determined via A-GPS are slightly less accurate than GPS GPS devices can determine location coordinates to within 1 meter accuracy
Cost: It costs money to use A-GPS devices on an ongoing basis because they use mobile network resources. GPS devices communicate directly with satellites for free. There is no cost of operation once the device is paid for."
Checkout last 2 points about Reliability and Costs. As a wifi-only p3113 user, having the ability to connect to GPS sat (even with no internet) would be a HUGE plus. So I would love to know how this bluetooth workaround works!

Have you tried? With wifi off I lock on to GPS in 2 seconds. Offline maps navigation works perfect... what more do you want?

Oh and from Wikipedia...
Assisted GPS, generally abbreviated as A-GPS or aGPS, is a system which can, under certain conditions, improve the startup performance, or time-to-first-fix (TTFF) of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers.

Well, instead of buying a GPS, I added some money and got a 7inch tablet P3113 also.
I have no tried offline GPS yet, how accurate is it? does re-direction work? which app would you recommend?
thank you

Accurate enough? Yes redirection works. Google maps has an offline feature. Or you could try navfree.

I love it when people are always confused about A-GPS.
A-GPS is BETTER than just GPS.
Assisted GPS means, that instead of just relying on the GPS satllites, it helps setting the position from WIFI and cell network.
It does NOT cost any money.
It is also handy, when you are indoors, so your device does not get a position fix from GPS satellites.
Besides, this samsung receives the Russian GLONASS satellites in addition to the American GPS, so its very precise.
My 10.1 tab2 (has the same receiver) sees 15+ satellites indoors!
GPS test shows precision down to 1m.

A-GPS need data connection
Hi, these posts are great to explain the difference between the A-GPS and regular GPS, but what happens if you do not have a data plan on your tablet and you are not in a wireless range. There is no way to activate the GPS.
The only way I have been able to use my no data Samsung 10.1 is to activate the GPS while in a wireless area then I can go for a drive (will always stay connected). If I would try to activiate the GPS on the road, I am out of luck.
Any work arounds?

Tether your phone to it....or. ... dont use a tablet for directions use your smart phone....and if you tell, e you dont have one then go return your tablet and get a real phone...

GPS works fine away from wifi on my tab-2 7 inch. It has real gps and doesn't need a wifi connection. You do have to turn it on in system seyyings though,

I have a Tab-2 7 inch with no G-whatever. The GPS is real and doesn't need anything other than to turn it on. It works fine. Try "GPS Test" it will tell you what is going on.
Just a point, an external GPS module will have about 1/2 the positional error of the built in GPS if you have WAAS or equivalent DGPS coverage. I get about 30 feet peak to peak error with the built in GPS and about 15 feet with my external Qstarz unit.

Tethering
Tethering your phone for GPS use will eat up your data plan. T-Mobile for example will limit your roaming data bucket if your phone is not within their network. The GPS feature of tablets is nice and the maps are large but I use a separate GPS unit for long distance driving and there's no extra charges. I bought a unit from Costco with free map updates for life! I would rather tether my tablet for internet use while on the road, it breaks the boredom with your passengers and they can watch Netflix too, depending on the signal. I do find that there is a lag connecting to the internet because the signal has to refresh with new tower signals.

Do you have to have a WiFi signal to use the Gaps? I lobe using my tablet in my truck but don't always want to connect my tablet to my phone

Assuming you mean A-GPS, no, the A- bit (assisted) needs data but that's just to speed up the initial fix time.
However, if you want to do something useful with the information about where you are, you may need a data connection; Google maps for example needs a data connection to get the maps, unless you have pre-cached them for the area you are in.
