SUMARE PAYLOAD

CONTENTS Objectives. Sensors choice. Sensors performances. Implant possibilities. Sensors conditioning. Schedule. Sensors integration drawings. Fins navigation trials. Fresh water tank measurement sensors. 2

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

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

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

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

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
