To electronically locate yourself on earth, you do not need a connection to
anyone else. All you need is, first, a map and, secondly, to receive the
GPS signal sent out by the satellites and know how to process it. To receive
a GPS signal, all you require is a GPS receiver. It's a radio receiver just
like any other. For confirmation see
Most android tablets and a good many Windows tablets have GPS receivers
built in. If they don't, you can get a small Bluetooth device which acts as
a GPS receiver. In neither case, though, do you need a connection to the
internet to know where you are in real-time. There are, of course, programs
which use a combination of the GPS chip and an internet connection to locate
you. Having an internet connection allows you to download maps as you need
them, to obtain updated information on a business (the most obvious example
in the blindness specific apps is blindsquare, which uses 4square's data
which it fetches from the internet), to send your location to others, etc.
However, these services are auxiliary to GPS, they are not GPS itself. There
are tons of GPS devices which are simply unable to transmit anything and can
connect to nothing. See, for example, some of the products made by Garmin
for cars and boats. They don't talk to anything except, perhaps, the car's
speakers, but they receive the GPS signal and can tell the user where he is
and how to get to his destination.
I should say that some companies have decided, in their phones and tablets,
to use cheap GPS receivers and use what is called assisted GPS to get a
better location. This uses a rough GPS signal to get started and narrows the
location down by seeing what wireless networks are in the area, what
cellular site the device is connecting to, and so on. As a manufacturer,
this allows you to save a little on your GPS receiver and the customer won't
As for Google maps, keep in mind that it relies on Google's servers for the
maps in most cases. Therefore, it obviously dies if you have no connection
to the internet, it can't talk to Google. Products like Nearby Explorer,
however, get their maps in one big gulp. They then use the GPS signal to
know where you are on the map and to direct you to wherever you're going or
to show you what's around you.
I hope that's of some use.

Josh, Perhaps you're not understanding what I'm asking. Fine and dandy that
it downloads the maps but maps whether on a tablet or on a piece of paper,
are completely worthless unless one and/or the device have a way to locate
you in the environment, which is where GPS comes in. GPS has to have some
way of contacting and accessing the global positioning satellites so as to
figure out where you are so the navigation app can further guide you.
Without this outside data there's no way to know where you are and the map
So again, is it just a list of directions that you follow as in step 1, go
to 7th avenue, step 2. take a left to 3rd street, step 3. walk
10 yards and you'll be in front of the pizza joint which you can do by
paying attention to what you're doing and without the GPS updating your
position, or are you claiming that it somehow magically is capable of
updating your location without any connection and giving you the next step
to follow when it's the correct time?
I've had experience with losing the GPS signal and Google Maps falls on its
face until it can reconnect with the satellites, so I'm really interested in
knowing if there's some magical way for it to locate where you are and keep
directing you without the need for any connection at all.

ok the scoop on nearby explorer for android.
1. it uses offline maps. the maps get downloaded into your device's
main storeage area and the download will take 2 or 3 hours to complete.
2. after the maps are downloaded and installed. you can start using
3. you can use nearby explorer with wifi and data turned all the way off.
4. you do not need any data or any wifi at all whatsoever to use
nearby explorer after of course you have downloaded the maps.
5. the map download is a one time thing. you download the maps one
time and then you just forget about them.
6. nearby explorer has a settings menu for different modes such as
driving and many many other things.
7. again, you do not need wifi for nearby explorer. you do not need
data for nearby explorer.
8. there is a version of the app, that is free, called nearby explorer
online. nearby explorer online free version does require data, or wifi.
because nearby explorer online free version does not let you download
any maps into your onboard storeage. therefore you need data at all
times for the nearby explorer online free version.
both apps are found in the play store.

Interesting. So how does it keep track of where you are while driving
in a car? Or does it just provide you with driving instructions as in
a list? I think what you're saying is that you can use an app that
will provide you with directions but the tablet can't use GPS without
some sort of external connection to either a data plan or wifi.

reason is because nearby explorer has all its maps and points of

Sorry to rain on the ardent support for Android but both Olusegoon
and Josh claimed that using GPS on the tablet would not be an issue...
That would be true if the tablet could use a data plan which most
Android tablets don't. You could use GPS if you were in range of a
wifi signal but in a car that would also be doubtful. If the tablet
was tethered to a smart phone then it would be possible to do it on
the road, but then why use the tablet since the smart phone could
do the same?
I use Android, iOS, and the Fire OS so you know.

Again, you are speaking so broadly that there is no way to know

I'm not sure what to say about your comments about apps. I'll let
others comment if they have experience or comments about app
accessibility or their results trying to get developers to make

Gene, I like skeptics! And, since you don't use an Android
device, I'm not about to confuse or convince you to get one. The
controls you referenced are no issues for me on my Shiny Android
I don't write in this space for purposes of impressing the wind!
I share information based solely on personal experience whether
it's by way of experimentation, or by some other direct means. I
live and breathe Android!
If it weren't working for me, I won't be working on THROWING
WINDOWS overboard for Android.
I will state here for the records that I DO NOT currently use any
bluetooth or physical keyboard of any kind with my Shiny Android
toys! I use the touchscreen exclusively; I am getting work done,
and, when I have issues worth addressing, I write directly to the
app developer in question and get results. I just sent a note to
CoCard Merchant Services, the developer of the CoCard Restaurant
app; in my note, I am seeking to know why the app changes my
screen orientation from Portrait to Landscape. I also visited the
issue of unlabeled buttons. perhaps I'll read from this developer
within the next few hours, or, by the end of the week. What's
important for me is that I can talk to the developer and get
results! And, if no results are obtainable, I simply abandon the
app and its developer and move on to something else.
Since I began embracing technology and using it to make things a
bit better for me with regards to what I do, I've never had so
much luck in reaching developers until I wrapped my arms around
the Android platform. So, I can, and I will, defend my platform
to the best of my ability because it is WORKING FOR ME as
I don't pretend to be a guru at anything; I typically will hardly
ever recommend a particular platform over the other; but I'll
discuss what I do that's giving me achievable results! I'll let
iOS enthusiasts speak up, but, as for me, Android rocks my boat
and I'm sticking with it!
