High sensitive 24/7 observation and monitoring system, which allows an optimized responding time against any unwanted asymmetric threats. With the harbour and coast protection system of STL, the Navy will have the general capability to detect unknown threats by passive measurement of the signals of an invader. The observation can be conducted for surface and subsurface surveillance. The advantage of the passive detection is that an invader will not recognize he is under monitoring and observation. This increases the moment of surprise and is a big advantage for the naval staff.All this is made possible through an optimal use of available high technologies. Our 3rd generation system is based on STL‘s high resolution data acquisition, highly sensitive preamplifiers in combination with UEP electrodes, very low noise magnetic field sensors, acoustic sensors with highest accuracy, together with state-of-the-art underwater and computer technology.

The core of the system are the multi influence sensors, which are connected to a safety chain. The size of the area that can be protected is completely customizable and depends on the number of used multi influence sensors and distance between them, influenced by water depth.
Furthermore, the multi influence sensors itself are also available in various configurations. The standard version is sensitive to magnetic fields, fully equipped, however, they are able to measure the following signals:

– Magnetic fields
– Electric fields
– Acoustic signals
– Seismics
– Pressure
– Temperature
– Conductivity
– Current

Type : intrusion
Applications : for harbors, for coastal areas, subsea
