CLS, your trusted partner for maritime security

As governments face rising levels of marine traffic and piracy at sea, along with accidental or intentional pollution, they strive to make their maritime domain safer and more secure. CLS offers integrated solutions to support government initiatives at sea. Our solutions include a wide range of services based on proven space technologies. As a result of 20 years of close collaboration with private operators and government agencies in charge of maritime surveillance, we have a proven track record in identifying and tracking ships, detecting illegal fishing and spotting oil spills. Our services help provide effective, well-planned management of maritime safety in a number of different areas:

  • Track ships around the globe
    The IMO (International Maritime Organization) has set up a long-distance ship-tracking system known as LRIT (Long Range Identification & Tracking). Every government is under obligation to acquire a LRIT infrastructure. CLS, which has been specialising in location and data-collection services for over 20 years, has developed a comprehensive offering of LRIT solutions for government maritime agencies the world over (data-processing centre, ASP telecommunication services and location beacons). Its offering is based on software solutions with proven capacities for monitoring fi shing activities under international agreements.

  • Monitor strategic sea areas
    There has been a fresh upsurge in piracy. Not only property and people but also commercial fishing resources are under threats, not to mention intentional or accidental pollution. Alongside its data-collection and location systems (LRIT, AIS, VMS and coastal radar systems), CLS offers a wealth of satellite radar information to monitor operations at sea and help authorities detect illegal fishing, oil spills and illegal trafficking.

  • Launch and coordinates operations at sea
    To further government initiatives at sea and provide a decision aid for maritime authorities, CLS has developed Thémis. This one-of-a-kind platform is the fruit of years of expertise in data fusion and display. Data on location, oceanic conditions, satellite or coastal radar, etc. is fed into the platform to help decision-makers better assess the situations. From the high seas to the coast and on any part of the globe, CLS helps authorities gain a deeper, real-time insight into the theatres of operations. This is CLS's contribution to improving government operations at sea.

    Long Range Identification and Tracking (LRIT)

    Starting on January 1, 2009, under the International Convention for the Safety of Life at Sea (SOLAS), all passenger ships, high speed craft, mobile offshore drilling units and cargo ships of 300 gross tonnage and upwards regulated by the 160 Contracting Governments of the International Maritime Organization (IMO) must be tracked with a Long-Range Identification and Tracking system.

    To comply with this regulation, these craft must be fitted with Long Range Identification and Tracking (LRIT) equipment programmed to transmit the identity of the ship and its location. The LRIT communication capabilities of the on board equipment will have to be certified by an ASP (Application Service Provider) recognized by the Administration, or by an authorized LRIT Testing ASP.

    Contracting Governments must implement a national LRIT Data Centre or join a Regional/Cooperative LRIT Data Centre, to which ships will report their positions four times per day. In addition, these centres shall be capable of communicating amongst themselves and exchanging position reports upon request. Contracting governments will also be able to track any ship within a 1,000 nautical mile zone of its coastline, no matter what flag it is flying.

    CLS proposes a complete range of LRIT products and services, from implementing LRIT data centers to providing satellite data (Application Service Provider) and may also furnish LRIT compliant terminals. CLS has operated satellite systems for vessel tracking for over 20 years, thus offering you the best possible accompaniment in LRIT implementation.

    SAT-AIS, a key component of the CLS Maritime Surveillance Services Portfolio

    Following the advent of space technologies for satellite monitoring of AIS signals, CLS worked closely with maritime authorities, navies, law enforcement agencies, commercial fleets, international organisations and space agencies to develop new SAT-AIS solutions, drawing on its experience as Integrated Maritime Surveillance Application Service Provider in processing ARGOS, AIS, IRIDIUM, INMARSAT, Synthetic Aperture Radar(SAR), Optical Images, Weather Forecast, INTELLIGENCE sources and LRIT data.

    In this respect CLS for instance developed the European SAT-AIS Data Processing Centre (EU SAT-AIS DPC) for ESA/EMSA and a key part of the IMDATE (integrated maritime data fusion platform for the EMSA).

    This SAT-AIS DPC offers further processing capability towards enhanced SAT-AIS data. Such a Data Centre collects and processes billions of messages from several sources, checks message integrity, predicts AIS messages and generates configurable warning messages.

    SAT-AIS solutions provided by CLS are also used for different operational needs like facilitating Short Sea Shipping, fight against illegal activities in the BLUEMASSMED project, Increase the Maritime Domain Awareness in Indonesia, Perú, Japan, fight against illegal pollutions and support customs authorities for instance or other environmental monitoring needs.

    Fleet monitoring services

    In addition to working with governments, CLS has developed a wide-range of services for private companies. Our fleet monitoring service capitalizes on our expertise in data fusion and display and provides real-time monitoring & cost optimization for fleet managers. Our online fleet management service includes:
    • Reliable & secure vessel tracking

    • Advanced fuel & time savings for operational efficiency

    Preventing Piracy

    CLS proposes ShipLoc, a service for merchant fleets which provides vessel monitoring by satellite, warning control and provides meteorological information.

    ShipLoc responds to the SSAS (Ship Security Alert System) requirements defined by the SOLAS international convention Chapter XI - 2/6. ShipLoc service uses discrete beacons installed on board. ShipLoc allows the commander to activate the alert signal in case of a threat on board. Then the message is transmitted to the ship-owner and to the IMB (International Maritime Bureau). Daily position reports with boat's heading and speed are delivered on detailed maritime maps. In addition, some alert measures can be defined by the ship-owner. As an example, he could be informed about any heading and speed modifications in risky area.

    ShipLoc has already been used in rescue efforts after acts of piracy.
