SyDELOES ® system is designed for detection and localization of sub-marine vehicles (divers, torpedoes, submersible,...). This system can be active when it operates with  mXmit® transponder onboard on the vehicle or can be totally  passive when only known acoustic signature of the vehicle is detected.

SyDELOES ® system is composed of a set of intelligent acoustic receptors (mRec®). Each receptor allows to detect and code up to 31 different active codes and to detect also up to 4 known acoustic signatures.  A localization system is associated with each receptor embedded in a buoy.

Each receptor provide its own signal processing and is connected to the main processing central unit by fiber optic or specialized radio data link.
