I have a question about GPS software on smartphones. Should GPS software require a live (cellular) data plan? I have been told by several people that GPS requires a data plan. I am under the impression that GPS uses data from gps  satellites, and shouldn't require cell data. Lumia's Here Drive worked this way, when I had a Windows phone. Several Android devices, and an iPhone, that I've used don't actually work without a cell plan. Is anyone aware of any Android apps that work just by using the gps  satellites? Thank you, tammerlane.

For all 3,you 1st have to download maps to your device,then you can run those apps in offline mode.....

To your question you ask. No GPS does NOT need cell data. What most ppl don't realize is that most GPS apps want you online for DL other information that is NOT GPS related.

 

Like google maps, you need wifi or cell data for your GPS to tell you where you are for it.

But if you have something like a GPS compass on your phone. It only needs the GPS, to get the info and show it.

 

So, make sure if you need GPS for something like if your lost and you get no wifi or cell data in the middle of no where its an app that only gives you GPS location (longitude and latitude). Anything that trys to show a map or something along that line with your GPS info then, yes you would need wifi or cell data.

 

Hope that helps you some hun.

I was a tester for 'Here' and have to say BE CAREFUL.  It works off line, sure, but use common sense.  Just because the map says there should be a corner and turn, please look before you turn into a house or farm animal (Brazil)!  Before you go on a trip, update the map of where you intend to travel to.  I suggest Waze to coordinate with traffic and see real time goings on.

Thanks for the help, peeps. I was trying to get a tablet that I recently purchased to use GPS while offline. It rarely finds its position. Even the best software doesn't help, if the device doesn't work properly. I have had 10 or 11 Android devices that the GPS was unable to determine the devices position - unless I had a paid data subscription. Android calls this 'high accuracy mode'. I doubt that cell towers are more accurate that GPS satellites. I suspect that somewhere along the line, from OS. to manufacture, to carrier that the service is rendered nonfunctional. I put this to motivational factors - 1) profit for selling data plans, 2) reporting your location. BTW, I have had a Lumia 520 and currently have a Lumia 640, both Windows phones, that find their location instantly and accurately - without a data plan. Imagine that, tammerlane.

I recently purchased a Galaxy 7S edge. While doing so the sales person kept pushing "HUM". A device that plugs into the cars diagnostic connector to connect to a Bluetooth speaker and the 7S. He kept claiming that it had a satalite connection. I looked up HUM (www.hum.com) and found no info an any GPS capability, so beware, You must have a data plan, although the sales people insist that you do not. I also find no info that the 7S actually contains a GPS receiver. Still researching through the hype by Verizon.

sjprj: Specs on Galaxy 7S Edge say it has: A-GPS, GLONASS, & GPS capability. This is the basic requirement of GPS. Question is, how will the manufacturer/carrier use the function. They make $$ from data, not free stuff.  tammerlane

A-GPS and GPS are different navigational aids that both use information from satellites to determine their exact location on Earth.

GPS stands for Global Positioning System. A GPS device communicates with 4 or more satellites to determine its exact location coordinates (latitude and longitude) anywhere on Earth. It works in any weather as long as the device has a clear line of sight to the satellites.

A-GPS stands for Assisted Global Positioning System. While it works on the same principles as a GPS (explained below), the difference here is that it gets the information from the satellites by using network resources e.g. mobile network, also called assistant servers.

A-GPS is faster in finding the location but GPS gives a more precise location information. While there is no additional cost involved in using GPS devices, an A-GPS has additional cost involved because it uses services and resources of the wireless carrier's mobile network. Some A-GPS models have the ability to link up to GPS satellites directly in case the assistance server is not available or if it out of cellular network coverage area, but GPS devices cannot log on to a cellular network.

GLONASS is an acronym, which stands for Globalnaya Navigazionnaya Sputnikovaya Sistema, or Global Navigation Satellite System. GLONASS is Russia’s version of GPS (Global Positioning System).

How is GLONASS different from GPS?
GPS developed by USA has a network of 31 satellites covering this planet and has been widely used in commercial devices like mobile phones, navigators etc.

GLONASS is developed by Russia originally started by Soviet Union in 1976. This has a network of 24 satellites covering the earth.

Advantage of GLONASS over GPS (GLONASS Vs GPS)
There is no clear advantage other than accuracy over GPS. When used alone GLONASS doesn’t have that strong coverage as GPS has, but when both used together certainly increases accuracy with coverage. And it is more useful in northern latitudes as Russia started GLONASS originally for Russia.

The accuracy is an advantage of GLONASS with up-to 2 meter of accuracy. GPS + GLONASS allows your device to be pin pointed by a group of 55 satellites all across the globe. So when you are in a place where GPS signals are stuck like between huge buildings or subways, you will be tracked by GLONASS satellites accurately.

 

 

as stated above by others. in general, off line navigation apps like i-Go Sygic Navigon Co-Pilot etc' don't need data connection, only gps.  on line navigation apps like Waze Google Maps etc' needs date connection to download the specific map where you are and when you move to continue downloading the next map/data it needs in order to show where you are. off line apps are very big because all the maps you need are locally on the phone. on line apps are a lot smaller because they download only what they need to show right now.

Good info on this thread. But there a couple of things that are missing. Navigation maps can use data to download current satellite positions to quicken how fast it can set your location. Also, it can use data for traffic and other features. The other item missing is that current versions of Google Maps can be used offline:

well, it wasn't missing, just wasn't mention. navigation maps can use data to download current satellite positions to quicken how fast it can set your location but it's not mandatory. meaning, it will also work without an on line data but the first gps fix will be a little bit slower. the option to download off line maps is quite new in google maps and not everyone knows about it yet. some points to remember about google off line maps.....

 

1. You can get driving directions offline, but not transit, bicycling, or walking directions. In your driving directions, you won't have traffic info, alternate routes, or lane guidance. You also can't modify routes like avoiding tolls or ferries.

2. To save cell data and battery life, use "Wi-Fi only" mode. In this mode, when you’re not connected to Wi-Fi, Google Maps will only use data from the offline areas that you’ve downloaded. Before you use this mode, make sure you download offline areas.
