 FAA
WAAS Program Structure
To develop and field a system
as complex as the Wide Area Augmentation System, there
are a variety of underlying supporting activities.
The WAAS program consists of several
functional areas:
- WAAS Research and Development
- Focuses on ionospheric issues, antenna development
to mitigate multi-path, Alaska connectivity, and
the support of the WAAS Integrity and Performance
Panel (WIPP). The National Satellite Test Bed (NSTB)
enables a major part of R&D work.
- WAAS System Engineering - Provide
oversight of the WAAS prime contractor's work to
ensure that all aspects of the system engineering
discipline are being met.
- WAAS System Architecture -
Review and monitor the overall WAAS concept to ensure
that WAAS is being properly implemented.
- WAAS Software Engineering -
Review CDRLs and software-related contract deliverables
from the prime contractor (Raytheon) to ensure appropriate
S/W development procedures are being followed, including
RTCA DO-178B.
- WAAS WIPP Support - Guide development
of S/W integrity monitors for WAAS. Co-chaired by
FAA and Stanford University.
- WAAS Test and Evaluation -
Ensure that WAAS testing is adequate and complete.
- WAAS System Security - Ensure
entities without proper authorization cannot utilize
or compromise the WAAS.
- WAAS Transition and Field Support
- Ensure all supporting efforts are completed to
move WAAS from R&D, through acquisition, and
into an operational system.
- WAAS GEO SAT Acquisition -
Ensure the adequate number of geostationary satellites
to provide required coverage and availability.
- WAAS Process Improvement/integrated
Capability Maturity Model - enhance processes and
continuous improvement of these processes related
to the WAAS program.
- WAAS Risk Management - Identify,
analyze categorize, mitigate, and track WAAS-related
risks.
- WAAS Configuration Management
- Ensure all WAAS components, both hardware and
software, are managed and maintained in an appropriate
manner and in accordance to FAA requirements.
- WAAS Contracts/Finance - Manage
the prime contractor's cost, schedule, and performance;
and review all deliverables.
- WAAS Business Management -
Support and manage the WAAS budget process.
- WAAS Planning/Program Documentation
- Develop and maintain strategic planning documents
and Acquisition Management System (AMS) documents
required by the AMS process.
The FAA WAAS Project Team is responsible
for the development and acquisition of the WAAS; however,
to ensure a smooth and successful transition of the
WAAS into the FAA's other lines of business and into
the National Airspace System, there are several other
FAA organizations involved in the development and
acquisition of the WAAS.
These other FAA organizations include:
- ASU-240 (FAA Quality Assurance
Division) - These are FAA personnel located on-site
at Raytheon Corporation to ensure that Raytheon's
products meets their quality and reliability contractual
obligations to the FAA.
- AOP-1000 (FAA NAS In-Service
Management) - These are FAA personnel who support
the Deployment Planning Process, Standard Operating
Procedures, and WAAS Operations and Maintenance
Plan.
- ASU-200 (FAA Quality Assurance
Division) - These are FAA personnel who provide
part-time support onsite at Raytheon Corporation
to review software development activities.
- AND-720 (FAA Navigation Systems
Implementation) - These are FAA personnel who support
fielding activities, such as the commissioning and
deployment planning process involved in the Transition
and Field Support portion of the WAAS project.
- AND-702 (FAA Navigation Systems
Engineering) - These are the FAA personnel who provide
policy oversight on system engineering functions,
such as security, configuration management, GPS
Modernization, and participation in the Interagency
GPS Executive Board (IGEB).
- AOS-240 (FAA National Airways
Systems Engineering Division Operational Support
Directorate) - These are the FAA personnel located
at the FAA Mike Monroney Aeronautical Center in
Oklahoma City, Oklahoma, and represent the concerns
of system maintainers once the system is fielded.
Support activities include software support activity,
OT&E shakedown, technical instruction books
(TIB), ESTS Tools, maintenance technical handbooks,
and operational CM, and safety assurance.
- AIR-130 (FAA Aircraft
Certification Service) - These are FAA headquarter
personnel who set requirements based on FAA certification
criteria to ensure the WAAS is safe to use by aircraft
operating in the National Airspace System. Support
activities include requirements documentation, safety
assurance, and RTCA and GNSSP support.
