OBJECTIVE: Improve
and enable advanced multi-platform data fusion through development of Open
Architecture applications and integration techniques.
FINDINGS: It was possible to construct a data model
(ontology) that served broad C4ISR requirements and Combat System across
Air, Surface, Land, and Subsurface domains.
This project
was for an open architecture that would enable advanced Data Fusion (DF)
algorithms interoperating synergistically across
systems aboard Navy ships, submarines, and aircraft in both the Combat
System tactical and C4ISR Operational levels of war. The goal of this architecture was to
enable more extensive data fusion such as non-kinematic level 1 fusion,
level 2 and 3 complex assessments, broader scope of Situation Awareness and
Battle Management information, and level 4 adaptation. Goals were higher
quality data fusion through enforced integrity of integrated data
responsive to an open ontology and through the ability for multiple kinds
of fusion algorithms to interoperate autonomously yet synergistically.
NGFA is an ontology-based fusion architecture that
enables fusion agents to operate in independent, yet coordinated, manners.
For the proof-of-concept demonstrations, the NGFA ontology was instantiated
as synchonized relational database and object class overlays and tested
with: (1) Kalman tracking filters, (2) the Jonker-Volgenant-Castanon (JVC) association and
assignment algorithm, and, (3) a Bayes Net for ESM/ELINT classification and
identification.
After the
successful proof of concept, Silver Bullet developed a “Common Data Model”
(CDM) that was the centerpiece for a large team experimenting with
futuristic track data exchange across diverse multiple platforms and
domains (Air, Surface, Subsurface, and C4ISR). Silver Bullet led the development of
Common Data Adapters (CDA) across the teams that interfaced the CDM with
the existing AEGIS, SSDS, BYG-1, SQQ-89, E-2D, MH-60R, and C4ISR GCCS-M WebCOP and Composable FORCEnet
systems in NAVSEA, NAVAIR, and SPAWAR laboratories across the U.S. The result was successful and led to the
development of the Track Server, now operational on all AEGIS (CG-47 and
DDG-51) and SSDS (CVN, LHD/LHA, LPD, LSD) ships.
