• keyboard, trackball

• touch panel

• handle

• hard keys

• water cooling

• emergency cooling

• Challenge of passive sensors in comparision with active sonar or radar:

  Determine the range / distance of an object / target. The direction is easy to determin with the variety of different sonars on board of the submarine

• IDRS: “Intercept Detection and Ranging”, 10 - 100 KHz

• “Intercept”: Reception of other sonar signals, especially time-critical transmissions, e.g. noise of an oncoming / attacking torpedo, early warning or transient noises like opening of torpedo flap or hostile submarine before launching the torpedo, always short distance, therefore working at higher frequencies

• CHA: simple, mature solution, direction determined by 360 degree arrangement of hydrophone staves

• PRS: Passive Ranging Arrays, Distance to contact determined by radius of oncoming / incident acoustic waves

• Flank Array, Extended Flank Array: Low frequency, due to arrangement on port and starboard side and length, direction of object wrt own submarine can be determined

• Mine avoidance: active, very high frequency, short distance

• Broadband transducer array: active sonar transmitter, especially for export U214 type

• ONA: own noise analysis: spectral analysis of noise emissions from own boat (pumps etc.), supplemented by accelerometers fixed directly to the pressure hull (“body noise”, “Körperschall”)

• TAS in conjunction with FAS / EFAS nad / or CHA can give very exact information on distance and direction of an object
