Hello Every One
I am Looking for a solution or code about Dead Reckoning ability for GPS, there is some algorithms, but I really don't know how to implement the code in C,
the total Idea is we garb the Direction and Speed any moment from an acceleration Gyroscopic sensor and measure the new point coordinates based on 3 data:
1. Start position
2. Target Direction
3. target acceleration

The reference for Dead Reckoning algorithm is:
http://en.wikipedia.org/wiki/Dead_reckoning[^]

Can anyone help with the code?

Thanks

You need to head on over to the rent a coder or free lancer web sites so you can hire someone to write this code for you.

I doubt that the precision of the accelerometers in a usual handheld will be good enough to derive a dead reckoning position. Integration errors of the speed vector will soon cover anything else.

If you are talking about dedicated hardware, then you might look under intertia navigation systems, as Dave suggested in his solution below. This stuff is expensive (50k+) and usually used in airliners.

So, you're looking for an intertial navigation system? And you want someone to provide you the code??

That's not going to happen here. We'll help you with your own code, but were not going to just write your solution for you.

There's a bunch of links in the Wiki article you linked to. This is going to take some research on your part to come up with a implementation that fits your requirements. You're not going to just pull code from some site and expect it to work unmodified.
