Mobile underwater signature measurement system for submarines and ships STL Systemtechnik
STL's unique 26 bit ADC pioneers in a novel underwater system to measure magnetic and electric fields. Three or more sensor platforms are connected to a base station in a chain configuration by a single cable used for power and data transmission as well as for deployment and recovery. The analogue sensor front end is formed by 3 pairs of UEP Carbon electrodes followed by ultra low-noise isolation preamplifiers, a 3-axes low-noise fluxgate, and environmental temperature and pressure sensors.
The digital part is based upon a novel high performance 26 bit analogue-to digital converter. Consequent digital signal processing provide temperature and geometry compensated signal output.
The three magnetic and electric field vector components are complemented by a pair of high resolution tilt sensors to achieve the precise softwarealignment of the sensor platform with respect to magnetic North and the Earth's gravity centre. In addition the system can be equipped with sensors to measure acoustic and pressure signature as well as environmental information like water current vector, temperature and conductivity.
The sensor system includes also DGPS and, therefore, is able to track the target traces with high precision. All signal channel can be read out and visualized in quasi real-time.
