Simulation results show that the position error of the integrated navigation system is less than 15% (RMS) of goal error over long intervals, and even smaller in the area with evident anomaly gravity.

The main task is to research relation of all kinds of fault models fault positions and gravity anomaly linear structure signal maximum positions.

So-called gravity anomaly linear structure signal is derivative of gravity anomaly level total gradient on gravity direction, and the derivatives must be greater than zero.
