Hierarchical Two-Stage Framework for Environment-Aware Long-Horizon Vessel Trajectory Prediction

In three linesHierarchical two-stage framework for long-horizon vessel trajectory prediction under real ocean conditions. Combines long-term predictor with short-term Spatio-Temporal Graph Transformer on discretized maritime cells. Environmental module integrates currents, wind, wave height via cross-modal attention. Results: 25% improvement in ADE, 17% in FDE on Australian CTS data.
