Abstract
En 中文
• Physics-Informed Residual learning for underwater SINS/DVL trajectory reconstruction. • Physics-informed losses enable ground-truth-free learning of current residuals. • Uncertainty-aware three-factor gating safely injects learned priors into the filter. • Closed-form DVL scale-factor self-calibration within sparse GNSS windows. • 86–94% position error reduction over standard SINS/DVL with 4.44% GNSS.
