maritime awareness system

Maritime Awareness System (MAS):
Detect & Monitor Maritime Threats

Data fusion and in-depth analysis to build the most complete picture and deliver actionable intelligence.

MAS provides real-time and historical insights to maritime authorities, coast guards, customs, intelligence agencies and navies worldwide for area monitoring and vessel behavioral analysis.

oil spill monitoring

Oil Spill Monitoring:
Pollution Detection & Response

CLS helps detecting oil spills for operational response and support for recovery.

Using satellite imagery, we detect and identify oil slicks, calculate its drift with in-house algorithms and provide analysis reports with real-time and accurate analysis, leading to the identification of potential polluter.

search and rescue

Themis SAR:
Support to Search & Rescue Operations at Sea

We support authorities in the planning and coordination of search & rescue operations, enabling time-critical decisions to save lives at sea.

Themis SAR is an incident management system helping target search areas, calculate search patterns and determine resources to be allocated.


Patrick Roussel

(…) CLS provides us with an all-in-one means of real-time surveillance of our identified targets, for a wide range of missions and even in the most remote maritime zones (…)

(…) MAS also enables us to detect suspicious trajectories or behavior at sea. Supported by powerful algorithms and AI, the solution highlights ships requiring advanced control among the thousands of vessels transiting our waters every day (…)

MAS also integrates satellite acquisitions, enabling us to enhance our knowledge of our maritime territory.

(…) The CLS solution is the perfect complement to our existing systems, and is now proving indispensable in our day-to-day missions to combat illicit maritime trafficking in drugs, arms and human beings.
