Sea Current

The inertial navigation system error caused by sea current and log error greatly oscillates. In order to evaluate the effectiveness of damping attitude, the vehicles movement should be detected in real-time. For this reason, a novel adaptive level damped algorithm was presented in this paper. According to the characteristics of the movement of the ship, this algorithm has determined when to turn into the damp loop according to the change of acceleration. Theoretical analysis and Simulations results show that the adaptive level damped algorithm could damp most of the Schuler and Foucault oscillations period, and efficiently improve the precision of the PINS on ships.
