    • Fusing of a continuous output PDR algorithm with an ultrasonic positioning system 

      Thio, Vincent Martello Kwie Hoe; Aparicio, Joaquin; Ånonsen, Kjetil Bergh; Bekkeng, Jan Kenneth; Booij, Wilfred (2021-12-09)
      The availability of inertial navigation sensors in smartphones has facilitated the development of pedestrian dead reckoning (PDR) models on a large scale. These models often consist of a step detection algorithm combined ...

    • Multibeam Echosounder With Orthogonal Waveforms: Feasibility and Potential Benefits 

      Blachet, Antoine; Austeng, Andreas; Aparicio, Joaquin; Hunter, Alan Joseph; Hansen, Roy Edgar (2021-04-15)
      Modern multibeam echosounders (MBE) employ frequency-division techniques (FDT) to ensonify multiple sectors within the same ping cycle. This leads to improved performance in coverage rate, and yaw and pitch stabilization. ...
