Created: 21 April 1986 – subsidiary of the French Space Agency (CNES)⇒ Operating the Argos constellation (Advanced Doppler location)

Core activities: • Commercial operation of satellite systems for positioning, data collection, ocean observation and surveillance

• Developing added-value applications and services based on satellite remote-sensing data;

Applications to:• environmental surveillance• sustainable management of marine resources• maritime surveillance• oil and gas

Supported by: Cubic-I (i3) – CLS office in Japan

Principle and Technical Challenges

Protocole: SOTMDA (Self-Organized Time Division Mul tiple Access):• Future transmission slots reserved; • Self-organized cells ~ 40 NM in radius; • Transmissions as frequent as every 2 s; • 2 channels, each with 2250 slots per minute; • 27 message types (static and dynamic information); • > 70,000 Class-A ships; ⇒ NOT designed for reception from space.

SAT-AIS:• Field of view is large (~ 5000 km diameter, horizon-to-horizon); • Observation time up to ~ 12 min; • Many asynchronous SOTDMA cells in field of view simultaneously; • Transmissions from different cells overlap; • Receiver strategies required to deal with message collisions.⇒ Need for specific (CLS patented) spectrum processin g algorithms to

deal with message collisions: retrieve more message s & focus on a given ship/fleet of interest when processing the si gnal.

Background on VDES (1/2)

� Increasing need for communication and sharing of information in the maritime domain (shore to ship, ship to shore, ship to ship)� IMO, IALA and ITU are the leading bodies to regulate (express needs,

ask for new frequencies, define what to do with them, specify technical requirements, propose regulation updates)� The World Radio Conference (WRC-12) has made substantial

provisions for the maritime community in the VHF band:- Exclusive utilisation of current AIS1 and AIS2 by the maritime

mobile service in Region 2 and 3 (in 2025) - Allocation for the mobile satellite service for channels 75 and 76

for long range AIS (new message 27)- Identification of the channels 27, 28, 97, 88 for testing future AIS

applications, e.g. Application Specific Messages (ASM)- Identification worldwide of channels 24, 84, 25, 85, 26, 86 for

utilisation of digital systems

Background on VDES (2/2)

� Expanding use of AIS has caused significant increase in VHF Data Link (VDL) loading which has become an active concern at IMO and ITU and for maritime administrations in general:

- AIS is well recognized, important tool, effective and useful technology, SOLAS vessels (Class-A)

- Too much !: AIS SART, AIS MOB, EPIRB AIS, AtoN, non SOLAS vessels (Class-B), ASM...

- While AIS is a navigation system, not fitted for data exchange

� Agenda Item 1.16 for WRC-15: “consider regulatory provisions and spectrum allocations to enable possible new AIS technology applications and possible new applications to improve maritime radiocommunication”

CLS and VDES

� CLS already deeply involved in VDES definition and design at IALA, ITU and IMO. � Currently under contract with the European Space Agency (ESA) to

complete a preliminary study: service requirements and mission, system, architecture requirements � Key stakeholders (maritime administrations, space agencies, regulatory

bodies and industry) already involved.� Test bed and demo with terrestrial and satellite prototypes scheduled for

2015/2016. � CLS is inviting administrations to join the on-goin g study to express

their needs, constraints and expectations.

CLS LRIT Capacity Building

LRIT for SAR missions

� Example with LRIT:

Page 19

LRIT e-NAV test bed (1/2)

� Context: � LRIT: IMO SOLAS regulation. � Sharing of ship positions between all SOLAS Contracting Governements� e-Navigation requires sharing of information� COMSAR-17 report: “explore possible use of the existing LRIT shore-

based infrastructure to facilitate exchange of certain e-navigation information in the future”� CLS: major LRIT provider worldwide (JCG, USCG, EMSA, Chile etc.)

� Objectives of the test bed: � Demonstrate, through a given use case (SAR) interest and feasibility to

exchange useful data via existing LRIT infrastructure� Provide at next IMO NCSR-1 recommendations on the best way forward

(technical changes required, main challenges, cost benefit analysis, realistic planning)

COSPAS-SARSAT (1/2)

� A new space segment: Medium Earth Orbit (MEO) satellites ~20 000 km altitude 3 GNSS constellations: Galileo/Glonass-K/GPS-III 72 SAR payloads (repeaters) (MEO)LUT receiving & processing capabilities System integration, testing and commissioning Experienced CLS staff for training and system maintenance Local and remote 24/7 support

� And a new ground segment: MELOUT Upgraded or new MCC

� Compliant with the existing system: Existing beacons Second generation beacons under preparation

Page 22

COSPAS-SARSAT (2/2)

� Now...: System under deployment and under qualification Partial system in place but still not operational Localization are not enough reliable/precise and availability is not guaranteed

� ... 2015 Demonstration & Evaluation phase (D&E) Technical & operational tests conducted to qualify the system Pre-IOC phase: optional phase (operational use of MEOSAR data as complementary data)

� 2016-2017: Initial Operational Capability (IOC) Data will be distributed to SPOC and between MCCs

� 2018...: Full Operational Capability (FOC) Full deployment of satellites / MEOLUTs MEOSAR system commissioned

Page 23

CLS & COSPAS-SARSAT

� Capacity Building: CLS, as a system integrator and beyond

� providing: Advanced customised MCC solution (MEO)LUT receiving & processing capabilities System integration, testing and commissioning Experienced CLS staff for training and system maintenance Local and remote 24/7 support

� and beyond: Integration of other relevant data sources into the platform (LRIT, AIS/SAT-AIS,

metocean data) + configuration of .xml interface for data requests Data fusion and algorithms (drift models, Information dissemination tool (to SPOCS and other MCCs) for additional data

⇒ Towards a fully user-oriented Search & Rescue Data Center, relying on other capabilities and data already available at Coast Gu ard level
