SAES - Sonar, Security, Anti-Submarine Warfare, Multi-Influence Devices, Naval Mines and Surveillance Systems

S.A. de Electronica Submarina (SAES) develops leading underwater battle space electronic equipment to meet the challenges posed in maritime-security, coastal-surveillance and anti-submarine warfare. SAES capacities excel in the following application areas:

• Sonars and submarine systems
• ASW systems
• Sonobuoy acoustics processing systems
• Mines and multi-influence measurement station
• Maritime coastal surveillance and harbour protection
• Land based systems for acoustic analysis, simulation and training

Sonar and submarine systems

SAES specialises in the study, design and manufacture of electronics and sonar systems for both military and commercial markets, highlighting:

• SOLARSUB DTAS: long range digital towed array sonar for submarines
• SOCILSUB: submarine cylindrical array sonar modernisation
• DAB-3: diver detection system
• SEAPROF: underwater acoustic propagation model
• CRV-ONMS: own noise measurement systems for ships and submarines
• SICLA: interactive classification acoustic system
• SVB: submarine battery monitoring system

Airborne sonobuoy acoustic systems

Sonobuoy processing acoustic systems (SPAS) provide the tactical mission system and the acoustic sensor operators with the means to detect, classify, localise, and track submarines and surface ships. This is based on the analysis of acoustic signals acquired by deployed sonobuoys.

SPAS has been qualified for installation on ships, maritime patrol aircraft's and helicopters. The system is fully integrated with other equipment as sonobuoy receivers, UHF radio, audio recorders and data link to conform a complete ASW subsystem. SPAS works in stand-alone mode or integrated with the platform mission tactical system

Fully integrated surface / air communication and sensor processing system

The sensor data link (SDL) provides a unique, fully integrated surface / air communication and sensor processing system. The SDL is designed to enhance and extend the ship's acoustic sensors (ASW), the anti-surface warfare (ASuW) and the anti-ship surveillance and targeting (ASST) mission extending ship's horizon of non-acoustic sensors (NAS).

SDL provide surface-to-air, surface-to-surface directional wide band tactical / sensor data exchange, and Ku-Band SATCOM capabilities, allowing full network concept warfare implementation.

Fast time sonobuoy acoustic signal analysis

The fast time analyser system (FTAS) provides post-mission sonobuoy acoustic signal analysis and intelligence gathering. This is done by simultaneously replaying and processing the sonobuoy acoustic signals recorded during operation in an either real fast or slow time speed.

The system includes different tools and graphic presentations allowing ground confirmation of recorded contacts and retrieval of non-detected contacts during the operation, as well as to classify new contacts.
These new acoustic signatures can be stored on digital format with the aim to build an acoustic intelligence database (ACINT).

Naval mines and multi-influence station

Based on a wide range of sensors and sophisticated algorithms SAES has developed a complete set of mines and multi-influence measurement stations, being a reference leader in the world market:

• The multi-influence range system (MIRS) provides real influence measures (magnetic, electric, pressure, acoustic, and seismic) in a real and controlled scenario, for surface ships and submarines
• The naval mines series MINEA (exercise and combat) are the most advanced naval mines being made today. The series comprises cylindrical, conical shaped and moored naval mines. All mines include triaxial magnetic, electric, seismic, acoustic and pressure sensors. The mines have a shelf system recovery activation order by means of an acoustic link or by programmed timing. The MINEA series have a programmable self-recovery, data collection and recording capability on the exercise version
• MILA-6C is a smart computer-controlled, time-fuzzed underwater limpet mine. It can be fixed by frogmen onto the hull of the ships or be used as a demolition charge. It has a conical shape and low weight in water

Acoustic simulation systems and training

SAES provides innovative solutions and sophisticated acoustic simulation systems such as tactical simulators, sonar simulators, sonar stimulators, sonar modelling, acoustic environmental modelling, engineering model for development and integration, interface and equipment simulators, and trainers.
