recommendations! Published in 2025 at "Measurement Science and Technology"

DOI: 10.1088/1361-6501/addbfb

Abstract: Autonomous underwater vehicles (AUVs) play an increasingly important role in underwater operations, and continuous and stable high-precision positioning, navigation, and timing (PNT) information serves as the foundation for their optimal performance. On an AUV, the… read more here.
