Mobile GPS needs no Internet

Technological advancements have given the complete Earth in our hands, but the question is how effectively we are using it. Most of the latest model mobile phones equipped with GPS, but most of us don't use it, thinking that it will cost a lot. If you are a smart hacker, you can use the mobile GPS at free of cost.

Before going into details , one should to know certain necessary things about GPS.
  1. GPS communication and mobile communication are two different things.
  2. GPS should work even without a SIM card.
  3. GPS needs some software to locate your position in a map.
  4. Without that software(maps) GPS just provide you longitude and latitude values.
  5. GPS has direct connectivity to satellites(32 of them orbiting our Earth, at lest 4 needed to establish a connection)
Now let us see what we need.
  1. A mobile phone with GPS receiver
  2. If it has GPS, there is a good probability that its having inbuilt software(like Nokia maps)
  3. Maps data for specific location or country
First two things are already in the phone, all that we need is Maps data for example Maps for India or Canada. This is the thing that costs money when you use the mobile communication to download the maps. Instead, you can completely disable the "going to Internet option" in the settings, then you can download the maps into your PC and transfer into your phone via USB or Bluetooth.
For that you can use Map loader software for Nokia phones. You should aware of the free features in the Nokia maps software. If you want extra features you have to pay for the licence. I think free features are sufficient to reach your destination, the extra features adds only sophistication to that.
