Abstract

Autonomous underwater vehicles commonly employ a Doppler velocity log to achieve an accurate navigation solution. In real-world scenarios, like when operating in complex environments, situations of complete Doppler velocity log outages may occur, leading to a rapid degradation in the navigation solution. To circumvent such situations, this paper proposes an approach to estimate the platform’s velocity vector based on past Doppler velocity log measurements and a motion model, for short time periods. At-sea experiments were conducted using two types of autonomous underwater vehicles, each with a different Doppler velocity log, to collected data for a total time duration of 90 minutes. This dataset was employed to show the benefits of using the proposed approach.
