Thanks to its core SDA technology, RTsys products all have very neat acoustic and data rendering and can be divided into three categories : • AUV (micro-AUV NemoSens; COMET AUV used for
Mine countermeasures and seabed mapping; SEMA Tar- get AUV used for Antisubmarine Warfare training); • Sonar Systems (handheld sonar for divers SonaD- ive; sonar retro? t system AS3I; sonar calibration system
