Abstract Aiming at the complex characteristics of the inertial navigation system carried by the underwater vehicle in the coning motion environment, we study and analyze the classic multi-sample algorithm, optimal multi-sample algorithm, uncompressconing compensation algorithm, and iterative algorithm based on quaternion differential equations. Using simulation experiments with the cone motion as the test input, we verify the accuracy and applicability of the attitude solution. The results show that the use of more than 3 sub-sample iterative algorithms for underwater gravity-assisted inertial navigation attitude calculation can meet the accuracy requirement of angular drift less than 1″/h.
