OBJECTIVES
The “Payload” will assume two main operational functions.
Monitoring of the volumetric evolution of sand banks.
Obstacles avoidance. 3

4. SENSORS CHOICE Altimeter. Obstacles avoidance.
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. 4

5. Measurement mode : Free run Measurement speed : 10 Hz
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° 5

6. IMPLANT POSSIBILITIES
1 : Risk on Payload structure (depth)
Obstacle avoidance sensor not possible.
2 : Risk on launching.
3 : chosen solution 6

7. Conditioning electronic : two output
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 7
