This research applies self-supervised learning via JEPA pretraining to enhance Positioning, Velocity, and Time (PVT) accuracy in dense urban environments where multipath interference is severe. By leveraging unlabeled GNSS data, the method significantly improves generalization for autonomous driving scenarios without relying solely on expensive labeled datasets. The core innovation lies in using deep learning architectures to correct range errors and quantify uncertainty, directly advancing machine learning applications in geospatial navigation.
Opportunities of Self Supervised Learning for GNSS: Evaluation of a Deep Learning-Enhanced PVT Algorithm
arXiv:2608.25674v1 Announce Type: new Abstract: This work proposes a Deep Learning Enhanced PVT algorithm to mitigate multipath interference in dense urban areas. A supervised objective jointly predicts range corrections and uncertainty, while a JEPA-based self-supervised pretraining stage improves representation quality. The algorithm is evaluated over diverse driving scenarios, substantially improving PVT accuracy, particularly for unseen harsh urban conditions. These results highlight the potential of unlabelled GNSS data to improve generalization performance.
