  • OBJECTIVES
  • The Payload will assume two main operational
    functions.
  • Monitoring of the volumetric evolution of sand
    banks.
  • Obstacles avoidance.

  • SENSORS CHOICE
  • Altimeter.
  • Acoustic high frequency transducer ( Resolution)
  • Obstacles avoidance.
  • The inner Mauve transducer is not available
    (Software limits / Discrimination).
  • The transducer is the same than for altimeter.

  • SENSORS PERFORMANCES
  • Measurement limit 50 m
  • Measurement mode Free run
  • Measurement speed 10 Hz
  • Power supply 12 or 24 VDC
  • Interface RS 232 or RS 485
  • Frequency 500 kHz
  • Conical beam 6

  • IMPLANT POSSIBILITIES
  • 1 Risk on Payload structure (depth)
  • Obstacle avoidance sensor not possible.
  • 2 Risk on launching.
  • 3 chosen solution

  • SENSORS CONDITIONING
  • Conditioning electronic two output
  • Two output are available on MMNS
  • 1 RS 232
  • 1 RS 485
  • The two electronic signal conditioning units will
    be connected on these outputs
