recommendations! Published in 2024 at "Journal of Field Robotics"

DOI: 10.1002/rob.22407

Abstract: Terrain‐aided navigation (TAN) is a viable method to achieve long‐term underwater navigation for long‐range autonomous underwater vehicles (AUVs). However, the high‐accuracy positioning results of most TAN systems rely on precise a priori seabed terrain maps,… read more here.

DOI: 10.1109/lra.2023.3234778

Abstract: Inertial Measurement Unit (IMU) plays an important role in inertial aided navigation on robots. However, raw IMU data could be noisy, especially for low-cost IMUs, and thus requires efficient pre-processing or denoising before applying further… read more here.

DOI: 10.1109/taes.2017.2667278

Abstract: In a vision-aided autonomous system, it is crucial to have a consistent covariance matrix of the navigation solution. Overconfidence in covariance could lead to significant deviation of the navigation solution and failures of autonomous missions,… read more here.
