“How does the GPS/ Glonass system work? Is it true GPS or just another wifi app or needs 3g/4g to work ?”

GPS/Glonass are Satellite Systems that have multiple satellites that will send a time-corrected repeated signal and their own position in the sky relative to the Earth. Your device needs only a GPS Receiver (antenna) to receive that (free) signal and display a computed Latitude and Longitude of your Receiver (Tablet) after receiving these signals from a few satellites. However, that information can be a very basic display of Latitude and Longitude / Altitude. If you are happy with that, then yes, your GPS works. If you are using some software like Google Maps or Microsoft Here Maps or Mapquest etc., you first need to download the local map-data onto your device (Tablet). This allows the mapping software to display your Tablet's Latitude/Longitude on a map, with other objects around, so that you can know your position relative to those object (e.g. Are you on the road, or off-road, are you on the east or west or north or south of a known point on the map. You still do not need any internet connectivity. However, if you next want to get all fancy and start navigating such that the software tells you as to where you are and tracks your speed/direction and also calculates a 'preferred route' to your 'Destination', from your 'Location', you then need some compute power that is on Servers on the internet and they need to constantly communicate with your device. (The GPS/Glonass does NOT receive any information from your device and has absolutely no way of knowing or recognizing your device as your device is NOT a Transmitter.) Your device can only communicate with Cell Towers (if you have a device with a SIM card, or if you use your Mobile phone as a Hot-Spot. And one it does get the chance to communicate with these Cell Towers (or any authenticated wireless routers on your way), you can get all the functionality of Mapping Software on the internet, like Google Maps, or Microsoft Here Maps or any similar 'system'. Have fun with your A10. :-)
Sorry, there was a problem. Please try again later.Hello there, kroot. Google Maps and other navigation apps use a data connection to connect to the satellites of GLONASS and GPS. The modern day smartphones come with A-GPS and A-GLONASS support, which brings features such as turn by turn navigation, location tracking and real time location info. I hope this was helpful. Have a great day.
