Model Based Systems Engineering for Tactical Data Link Systems


TECHNOLOGY AREA(S): Materials, Electronics, Information Systems

OBJECTIVE: Develop and demonstrate ability to identify, aggregate, and analyze distinct data types and formats to enhance the decision-making process during the technology assessment and trade-offs, design, development, testing, and qualification phases of tactical data link systems using Model Based Systems Engineering (MBSE).

DESCRIPTION: The goal of this SBIR topic is to develop a Systems Modeling Language (SysML) digital twin system model of the Multi-Functional Information Distribution System (MIDS) Joint Tactical Radio System (JTRS) terminal configurations. The MIDS Program Office (MPO) is interested in significantly improving and expanding its engineering support infrastructure to enable deployment of more efficient, agile, and resilient tactical data links systems models to expedite capability to the fleet. The MPO intends to implement a Model-Based System Engineering approach for all engineering activities that uses models as an integral part of the technical baseline including requirements generation and validation, analysis, technology trade-offs, design,implementation, and verification of a capability, system,product and/or technology throughout the acquisition lifecycle. A model-based system will enable unprecedented levels of systems understanding that can be achieved through integrated analytics, tied to a model-centric technical baseline and will support new DoD acquisition initiatives to expedite warfighting capabilities to the fleet [Refs 1, 2, 3].Implementing this type of capability would expedite correlation of relevant technical data, software, information, knowledge and technology trade-offs to enhance tactical data link development. This environment would provide substantial acceleration of development of solutions and technology transition resulting in reduced time and significant cost reduction of critical capabilities to the warfighter.Work produced in Phase II will likely become classified. Note: The prospective contractor(s) must be U.S. owned and operated with no foreign influence as defined by DoD 5220.22-M, National Industrial Security Program Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence and Security Agency (DCSA). The selected contractor and/or subcontractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances, in order to perform on advanced phases of this project as set forth by DCSA and NAVWAR in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material IAW DoD 5220.22-M during the advanced phases of this contract. NAVWAR will process the DD254 to support the contractor for personnel and facility certification for secure access.

PHASE I: Define solution(s) to develop digital twin system model of the MIDS JTRS terminal configuration. Outline model elements, including characterizing behavior, structure, requirements, and parametrics, that further refine trades in developing tactical data link systems. Solution must specify data storage and computational requirements and will identify existing DoD capabilities that may contribute to the desired end-state capability, identify capability gaps and establish a methodology to deliver needed capability. Information absorption and temporal requirements will be baselined during Phase I. Propose model simulations are strongly encouraged and could take several forms such as augmentations/plug-ins to existing SySML tools. Partnership with MIDS prime vendors is encouraged to help understanding of MIDS design and potential models they use. Partnership with NAVWAR 5.0 Digital Engineering Transformation Division is encouraged. Phase I will be UNCLASSIFIED, and the contractor will not require access to any classified data. Develop a Phase II plan.

PHASE II: Develop a prototype model based on the learning of Phase I effort. Validate and demonstrate the proposed data analytic capability leveraging existing DoD tactical data link infrastructure. Demonstrate the prototype system using MBSE tools identified in Phase I. Include, at a minimum, demonstration of a prototype tool or methodology on a small system(s) application that is representative of a portion of the tactical data link infrastructure, and documentation describing anticipated use of the tool. Ensure model adherence to SysML and Unified Architecture Framework (UAF) specifications, as well as eXtensible Markup Language (XML) Metadata Interchange (XMI) Standard, is desired. Endstate should ensure model can be used to inform tactical data link analysis including (but not limited to) requirements, impact, trade-off, behavior, interoperability or data flow.The expected TRL for this project is 5 to 6. Partnership with MIDS prime vendors is encouraged, but not required. Partnership with NAVWAR 5.0 Digital Engineering Transformation Division is encouraged.It is likely that the work under this Phase II effort will be classified (see Description section for details). Though Phase II work may become classified, the proposal for Phase II work will be UNCLASSIFIED. If the selected Phase II contractor does not have the required certification for classified work, the related DON program office will work with the contractor to facilitate certification of related personnel and facility.

PHASE III: Mature the model and extend use to multiple data link centric platforms within the Navy and private sector. Support or license the final product (s) and transition to the Government. The technology will have application throughout government and industry. Performers from component developers (e.g., Intel, Texas Instrument, etc.) to system integrators (e.g., LM, Boeing, BAE, etc.) could use these models to reduce costs in data link development. Partnership with prime vendors is encouraged, but not required. Navy seeks selected vendor to support transitioning of MBSE solution(s) across the Services.
