SA Electrónica Submarina (SAES) has been presenting at this year’s ‘Asia Pacific’s Flagship Maritime Defence Show’ (IMDEX ASIA) 2015" held in Singapore, to promote their products and services in that region.

The company, which specialises in underwater electronics, is sharing a stand NAVANTIA (R17) at the exhibition.

The event began on Tuesday 19 May and will last up to the Thursday 21 of May.

A representative of SAES said: "There is a worldwide growing interest in having data related to energy emissions in the underwater environment, as well as the acoustic, of the electric, magnetic, pressure and seismic.

"Furthermore, the underwater surveillance is crucial for countries that have extensive coastline in order to avoid intrusion into territorial waters."

SAES, as a specialist in acoustic intelligence (ACINT) and signature intelligence (SIGINT) brings IMDEX visitors the opportunity to know more about the products and systems based on these knowledge areas.

Systems for SIGINT

The SIGINT great advantage in the face of ACINT is that it allows the classification of a contact more accurately and in any situation and operating environment, due to the greater amount of information managed.

At present, this technique is used in an integrated manner in multi – influence systems, such as multi-influence range systems (MIRS) and multi-influence moored naval mines (MINEA) SAES developments, providing measures of all influences of any contact or threat, simultaneously.

MIRS – Multi-Influence Range System

The SAES multi-influence range system (MIRS) for surface vessels and submarines provides real influence measures (magnetic, electric, pressure, acoustic, and seismic) lets to obtain all signatures of the ship in different geographical locations, allowing the successful counteraction of threats.


The multi – influence range provides underwater influence measures in order to:

  • Establish the mine threat of the measured ship
  • Test and calibrate the systems for signatures reduction as active shaft grounding (ASG), degaussing systems, active cathodic protection (ACP), etc.
  • Test, calibrate, and configure the minesweepers
  • Develop and validate studies for signature reduction and influence propagation models (dipole models, boundary contour elements, etc.)
  • Provide a Data Base of signatures for:
    o Intelligence (SIGINT)
    o History evolution of the signature and ship maintenance
  • Evaluate new threats as combat divers, unmanned underwater vehicles (UUVs), remotely-operated underwater vehicles (ROVs) etc.

MINEA – Multi-Influence Naval Mines

Based on its experience in underwater sensors, SAES has developed a complete set of multi-influence naval mines (MINEA), at the forefront of the market that use a variety of sensors (magnetic, electrical, seismic, acoustic and pressure) to detect different physical influences of the target.

The family of MINEA products comprises three naval mines: cylindrical bottom mine, conical shape shallow water mine and moored mine. In addition, the Exercise MINEA version is available to be used for mine counter measures (MCM) training and to gathering intelligence information by measurement and recording of ships influence signatures.

Furthermore, the knowledge of this intelligence is essential to programming the fire algorithm of the combat units.


Today, asymmetrical threats in the fields of defence and international security make it necessary to deploy underwater protection systems for ports, drilling platforms, anchored boats, power plants, large oil refining companies, and any infrastructure of interest and extremely important which require protection.

DDS-03 – Intruder Detection Sonar

The high-frequency active sonar diver detection sonar (DDS-03) has been specifically designed for the detection of underwater threats, such as divers and manned and unmanned underwater vehicles (SDV, ROV or UUV), offering protection and surveillance against the potential threat in ports, critical facilities, shipwrecks, environmentally protected areas, special events, and anchored boats.

Additionally, the deterring system (DES) can warn non-authorised divers of being in a protected area and emit dissuasive acoustic signals if needed.=

SIDIS – Integral Security System

SIDIS configures itself as a net of nodes that can operate in a stand-alone way or making part of an integrated surveillance system. These nodes are characterised as multi-sensor (acoustics and non-acoustics), modular, versatile and high-performance systems.

The SIDIS design is based on a layer protection concept to increase its degree of effectiveness. Its adaptability allows the integration with other sensors and surveillance systems to configure wider control systems. The DDS – Intruder Detection Sonar, explained before, is one of the elements that composes this integral security system.

SAES also provides advanced technology in other naval areas:

  • Sonar and on-board systems: Development, manufacture and integration of sonar and others onboard systems such as sonar prediction systems, own noise monitoring, acoustic classification
  • Anti-submarine warfare: Sonobuoy processing acoustic systems (SPAS), integrated communications system (ROASW) and ground systems for mission support and acoustic intelligence, as well as trainers and simulators
  • Simulation and trainin: Tactical simulator for submarines. Sonar simulator / stimulator. Training systems for acoustic operators
  • SAES services: Engineering services, verification and testing systems, maintenance, aftersales support, education and training.
