Any Idea on how to develop a GPS for mobile phones?
There is a question running in my mind today and I want to find answers and I hope someone could help me. I have seen a GPS software for mobile phones that enables them to track their location anywhere in the globe. I've been curious about this technology and (if possible) want to make one for myself.
Most of the GPS software I found was developed using Java 2 Micro Edition (J2ME). The question is how would do this?
Where do I start?
What do I need?
I would appreciate all ideas so please help me with this one.
