C-Scope MSI

Multi Sensor Integration Unit

The C-Scope MSI gives the complete underwater picture 24 hrs every day. Data from different sensors are combined, and the number of tracks to be investigated by the operator are reduced. Interoperability is fundamental to the MSI, with its open architecture allowing the exchange of tracks and other information between several C-Scope clients and other network services.


Picture Compilation 

Data from active and passive sonars are received across the connecting local area network. Confirmed underwater tracks are transferred to the Command and Control module responsible for the Common Recognized Operational Picture (CROP). The underwater operational picture is presented overlaid map background. 

Track Handling 

The Track Handling function maintains the underwater track store. Tracks are input from internal and external sources and correlated and fused according to specific rules. Upon operator interaction, tracks are assigned classification and identification tags. In case of overlapping sonar coverage, this function ensures track number consistency. Track history is maintained and stored. 

Multi Sensor Data Fusion 

In case of sonar coverage overlap, the Multi Sensor Data Fusion function generates combined tracks based on feature based target tracking. Sonar data are fused at contact level taking into account above water track information, geographical information (sea maps), and false track information. 

Track Correlation with Static Information 

By comparing target position with geographical information and false track information it is possible to reduce the number of false alarms considerably. This is essential in harbour areas or close to the coast where the initial number of false targets may be very high due to reflections from the seabed, structures in the water column etc. 

Target Kinematics Examination 

Automatic and manual functions for target kinematics examination are provided. Classification of target into groups such as diver, assisted diver, school of fish etc are done by examination of course, turn rate, speed, radial speed and acceleration.
