AIS in Support of Maritime Domain Awareness
  • MDA is the effective understanding of anything
    associated with the global maritime environment
    that could affect the security, safety, economy,
    or environment of the United States.
  • A large part of MDA is tracking vessels AIS
    will meet a substantial amount of the vessel
    tracking requirements in support of MDA, but is
    not the only capability.
  • As an element of MDA, AIS will provide
    capabilities to
  • Receive, distribute, and use the information
    transmitted by vessels that operate AIS equipment
  • Take advantage of the functionality provided by
    AIS technology in support of all Coast Guard
    missions and national maritime interests
  • The information provided by AIS will
  • Support the nations maritime interests
  • Improve navigation safety
  • Facilitate vessel tracking beyond our
  • maritime borders

AIS Via Commercial LEO Satellite - System Overview
  • Concept validation payload
  • Partial solution in conjunction with other
    systems
  • Limited coverage (1-2 reports/day)
  • Potential for market that will expand coverage
  • Launch scheduled for March 06 capability
    approximately June 06

AIS signal processed onboard satellite remove
data to lessen bandwidth, meet reporting
requirements, etc.
AIS signal received by satellite no AIS
transmission from satellite
USCG receives data and incorporates into
appropriate command and control (C2) systems),
distributes to other users as appropriate
Processed AIS data sent from satellite to GES via
ORBCOMM data link
AIS data routed through NCC quality check,
satellite maintenance, etc.

Nationwide AIS Major Acquisition project
  • Goals
  • Fill in the gaps in AIS coverage
  • Enhance existing capabilities
  • Add new capability
  • Make the patchwork a network
  • Discrete regional systems to national system
  • Make the data usable
  • Verification AIS is a cooperative technology
  • Correlation, fusion with other data
  • Interoperability with other systems
  • Local C2 systems
  • COP, intelligence systems

AIS Technical and Policy Issues
  • Technical/System Issues
  • Volume of Data
  • Making it usable for achieving MDA including
    data validation, correlation and fusion
  • Integration with the variety of systems that will
    use AIS data
  • Storage of this large amount of data while making
    it readily available for analysis
  • VHF Interference
  • VHF data link (VDL) overloading
  • More AIS-equipped vessels, binary applications,
    other uses for AIS
  • May result in the need for changes to the AIS
    standard, changes to shoreside infrastructure
  • Policy Issues
  • System coordination transmit capability, slot
    assignment, binary application usage
  • Management and administration of binary
    applications
  • AIS data sharing
  • Use of AIS data
  • AIS Frequency allocation
  • Enforcement - VDL Police
