Thruster fault diagnosis method based on Gaussian particle filter for autonomous underwater vehicles

International Journal of Naval Architecture and Ocean Engineering, 2016
Autonomous Underwater Vehicles (AUVs) generally work in complex marine environments. Any fault in AUVs may cause significant losses. Thus, system reliability and automatic fault diagnosis are important.

Fish telemetry and positioning from an autonomous underwater vehicle (AUV)

Instrumentation viewpoint, 2010
We explored telemetry of transmitter tagged fishes from an autonomous underwater vehicle with a hydrophone/ datalogger processing code-division-multiple- access acoustic signals. Geolocation estimates used synthetic aperture and relative sound strength mapping.

Design of Autonomous Underwater Vehicle’s (AUV) Antenna System

, 2021
Havet symboliserar mysterium, passion och kraft. Men det mesta av havet, cirka 80 %, är okänt för människor. AUVs (Autonomous Underwater Vehicles) är en plattform där terrängkartläggning, biologisk mångfald och resursundersökning blir tillgänglig. Till skillnad från ROVs (Remotely Operated Vehicles) fungerar AUVs enligt sitt förinställda program som ...
