RESERVE SOCIETE SUMARE PAYLOAD

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

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

RESERVE SOCIETE 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. 4

RESERVE SOCIETE 5 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°

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

RESERVE SOCIETE SENSORS CONDITIONING Conditioning electronic : two output Two output are available on MMNS 1 RS RS 485 The two electronic signal conditioning units will be connected on these outputs 7
