Normally this is done by backing up the inertial measurements with GPS or

other radiolocation measurements -- what's holding you back from that?

For the project i am working neither can i use GPS nor i have other
measurements, the challenge is to find out if a Dead Reckoning system with
accelerometer, compass and gyro will be good enough to estimate the
position somewhat accurately ( equal to GPS or slightly less accurate, if
its more accurate even better).

North, east, and down are easy (for an arbitrary definition of "easy");
so is latitude. Find the local compass declination and that should
suggest a longitude. Only a few more measurements would be needed to
resolve any remaining ambiguity. Making a real system that's capable of
doing this would be ... challenging.
