  • Acoustic telemetry
    Y
  • Radio telemetry
    Y
  • Data sent to the surface
    acoustic underwater communication by a bidirectional serial link with up to 2 km range under water in order to transmit position data of the AUV, allowing tracking of the vehicle. It also recognizes a stop-signal from the surface station in order to interrupt an ongoing mission.
  • Control parameters sent to the AUV
    hybrid operation in AUV or ROV mode: real time data transfer and vehicle control up to 1000 m through plug & play fiber optic Ethernet
  • Emergency recovery procedure
    AUV surfaces by own positive buoyancy
  • Applications
    Mine counter-measure, rapid environmental assessment, hydrographic survey, scientific marine research, offshore windfarm monitoring, cable inspection, pipeline inspection, water supply tunnel inspection, insurance investigations, search and recovery, harbour protection, ASW
  • Distinguishable features
    ATLAS SeaCat is a hybrid UUV which can be operated in unsupervised autonomous mode (AUV) or as a remotely controlled vehicle (ROV) when attaching a fibre optical cable with 1000 m length (option). Due to its modular design (SwapHead) the SeaCat can be equipped with a range of underwater sensors in the payload section (nose cone) such as MBES, SSS, SBP, Imaging Sonar and Camera.
