Simulation on Integrated Gravity/Inertial Navigation System

Several underwater navigation methods are analyzed, and a new integrated navigation method is put forward, i.e. integrated Gravity/Inertial Navigation System. The background and the principle of this system are introduced, and the whole process is simulated by a visual simulation manner. The experiment results demonstrate that the gravity matching methods can restrain the increase of error of the inertial navigation system, and acquire high accurate underwater positioning.
