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 ...
