Adui, i have just started to have some fun in GPS then they may fail?

Haha.. wont fail i think.. US Air Force needs GPS so much in their navigation..

Let me show u how GPS works in iPhone..

When u click the button on the lower left side, then ur iPhone will the satellite.. at least 3 satellites are needed to locate ur exact location..

So at first u can see a big round circle showing roughly ur current position..

And then if u wait a little longer, then they will show u ur exact location..

They blue DOT will show ur current position in Google map..

It is very accurate for my current location in JB.. showing the exact location of my house..

Oh GOSH!! then u all know where is my house liao..

img_0004And then if i choose to move to a place using the GPS navigation, they will show the route..

Haha.. but mind u, it is not 100% correct..

And the route may not be the shortest..

And i have never tried before when driving..

Last time i tried but fail because i cannot get the blue dot when i’m in the car.. so cant really do much :P
