The Future Airborne Capability Environment™ (FACE) Data Architecture and Architectural Analysis and Design Language (AADL) are complementary modeling standards, both of which can be represented in SysML using SysML profiles. State Linked Interface Compliance Engine for Data (SLICED) is a behavior analysis tool from Adventium Labs which can evaluate the behavior of FACETM UoCs augmented with execution details specified in AADL. The FACE, AADL, and SLICED profiles and plugins for MagicDraw SysML enable a streamlined workflow for modeling and analyzing UoCs. This paper describes the relationships between these technologies and describes recommended workflows for using them in concert.
The data modeling aspect of implementing the Future Airborne Capability Environment™ (FACE) Technical Standard continues to be a challenge for numerous organizations. The process is considered by many to be too difficult or intractable for new programs. This paper illustrates some of the more philosophical and structural aspects of building a data model.
These concepts are introduced using an outlandish story that follows an engineer through the process of developing a model. It introduces the myriad concepts that modelers face when building FACE™ data models and notes developmental milestones with an indication of model sufficiency.
While this paper could be more concise and much more technical, data modeling is a challenging topic and we are doing our best to have a little fun with it. As such, abundant artistic license is taken. While the technical aspects are intended to be taken seriously, the rest of the paper is not. Enjoy.
This presentation will show the benefits of using a common standard service/protocol for the transport services segment (TSS) of the Future Airborne Capability Environment (FACE) Technical Standard, Editions 2.1 and 3.0. Using a common standard supported by multiple vendors simplifies interoperability between different TSS implementations as none of the optional capabilities like Transport Protocol Module (TPM) or translation are needed. The use case presented will highlight interoperability between ADLINK’s FACETM Certified Conformant Transport Services Segment (TSS) UoC using OpenSplice DSS and Real-Time Innovations’s Certified Conformant TSS UoC using Connext® DDS.
The Surface Navy presently lacks a comprehensive Modular Open Systems Approach (MOSA) for warfare system acquisition. A team out of the Naval Surface Warfare Center (NSWC), Dahlgren Division (NSWCDD) has begun investigating the Future Airborne Capability Environment (FACE) to determine if the FACE™ approach, or significant lessons learned from it, will help designers apply MOSA to future, warfare system designs. To investigate, the NSWCDD team applied portions of the FACE approach and the FACE Technical Standard version 2.1 to a representative integration effort. Using FACE Technical Standard version 2.1 and tools widely available at the time, the team represented portions of complex warfare system interfaces as a series of FACE data models. Using these data models, the team analyzed and then closed the integration space between a set of heterogeneous systems. The team observed and reported the effects of data model driven integration as this prototype system-of-systems evolved over time.
The promise of emerging open standards, Sensor Open Systems Architecture™ (SOSA), Hardware Open Systems Technologies (HOST), C4ISR/EW Modular Open Suite of Standards (CMOSS), and the Future Airborne Capability Environment™ (FACE) are being leveraged for Modular Open Systems Approach (MOSA) system development. These “best-of-breed” technologies are being used to design, build, upgrade and deploy systems to our warfighters that are more complex and more capable with higher technology readiness levels, lower cost and reduce development and integration schedules.This paper presents TES advances in utilizing Model-based Modular Open Systems Approach (MMOSA) meeting the need to verify systems against the open standards they are built upon in order to achieve the high goals of MOSA. TES’ AWESUM® processes and tool suite enable the rapid development of hardware and software solutions for multi-organization development and integration of complex systems that align with the operating environment and speed the process from concept through conformance.
This presentation provides an overview of modern Digital Transformation (DT) technologies that the FACE and SOSA standards may consider supporting Edge Computing, Containers & Microservices, Stream Processing, and Artificial Intelligence. These technologies enable the rapid results of Continuous Integration / Continuous Deployment (CI/CD) on cloud Dev/Test and DevSecOps environments to be provisioned across a variety of airborne platforms. It describes areas where these technologies can optimize limited computing resources on airborne and sensor platforms, increase airworthiness, and enable new capabilities. The author also ties these DT opportunities to key initiatives such as Autonomic and Semi-autonomic Unmanned Aircraft Systems (UAS) and Next Generation Air Transportation System (NextGen) initiative for the modernization of the US National Airspace System (NAS).
In any industry, the evolution of the solution space has become a complex system of disparate services, technologies and methodologies often achieved through the unification of legacy systems and new technologies, to remain operational and competitive in this ever-changing world. This presentation discusses the concerns, risks, challenges, and most importantly the benefits of using the FACE™ Reference Architecture, and specifically and especially the FACE™ Data Architecture, presented from the threefold perspective of buyers, suppliers, and integrators.
The Model Based Open Systems Approach (MBOSA), aligned to DO-178C, DO-331, AC 20-148, and AR 70-62, describes the use of TES-SAVi’s AWESUM® MBOSA modeling tools on two significant U.S. Army advanced capabilities efforts scheduled to support U.S. Army aircraft flights in 2021.This MBOSA is being refined and proven with two-sets of modular open systems approach (MOSA) software suites that will be hosted on U.S. Army advanced aircraft, namely the Apache Attack and Black Hawk Utility aircraft.This MBOSA software lifecycle modeling process and TES-SAVi’s AWESUM® MBOSA modeling tools support the lifecycle (i.e., requirements development, architecture and software design – high level and low level, systems data and semantic modeling, and eventual auto-generation of embedded software code aligned with the FACE Technical Standard, auto-generation of tests with artifacts, and auto-generation of the complete set DO-178C life cycle documentation). These products are purposely designed to support FACE Verification and Airworthy Qualification efforts.
How the FACE Approach can aid the DoD in the deployment of new technologies
Wide adoption of the FACE™ Technical Standard should reduce the schedule of getting new technologies to fielded systems. Benefits to the distribution of technologies that the FACE Technical Standard has provided are easily observable; other architectural approaches used throughout laboratory systems associated with the exploration of emerging technologies to fielded systems can further reduce these schedules within the DoD. A broader application of a common set of architectural approaches in technology demonstrators shows a clear path to realizing a more rapid adoption of new technologies. A Comprehensive Architecture Strategy (CAS) requiring additional architectural approaches could be applied to early demonstration systems, integration labs, and production systems; further reducing the lag from technology development to fielded capabilities across the DoD would be reduced.
Through the SOSA™ and FACE™ consortia, industry and the DoD have made significant progress in realizing Modular Open Systems Approach (MOSA) for C4ISR systems. The results are system designs that have enhanced upgradability, interoperability and scalability. The improved interoperability, however, can come at the cost of an expanded attack surface for adversaries that jeopardizes the security of the systems. This paper is aimed to address such issues by describing a zero-trust security approach for MOSA system architecture, and its applicability to SOSA based systems.
Current systems and sensors provide an ever-increasing amount of data to operators. Whether the operator is on the ground, in an aircraft, or even on a ship, the vast flow of data needs to become useful material that informs and creates decision paths. With thegreater role of Artificial Intelligence (AI) in decision paths, the quantity and capability of sensors has caused an exponential rise in the amount of data being transmitted within sensor systems. Sometimes overlooked, are the connections going between host platforms and devices. Standards bodies pay careful attention to the packaging of printed circuit boards (modules) and the software that runs them. However, the perceived mundane topic of connecting chassis to the functional elements is not given as much consideration until after the baseline standards are established. Of particular importance is the electrical performance of these interconnects. This is especially true as data requirements continue to increase along with new systems development. This paper will discuss the issues that are increasing the importance of connectivity between boxes and how developing standards can benefit everyone in the supply chain. The work of the Electrical/Mechanical Subcommittee will summarized along with anticipated future efforts to meet the ever increasing needs for more data.
Imaging polarimeters have been used in remote sensing applications for natural clutter suppression and target detection and tracking applications. Polarimetric measurements are often uncorrelated with measurements of the magnitude and spectral content of an electromagnetic signal and can provide additional information about an imaged scene. Division of Focal Plane (DoFP), or integrated microgrid polarimeters, are one method for collecting polarimetric information in a dynamic scene. DoFP polarimeters typically consist of a 2x2 mosaic of linear polarization filters overlaid upon a focal plane array sensor and obtain temporally synchronized polarized intensity measurements across a scene, similar in concept to a Bayer color filter array camera. However, the resulting estimated polarimetric images suffer a loss in resolution and can be plagued by aliasing due to the modulated microgrid measurement strategy. Numerous demosaicing strategies have been proposed that attempt to minimize these effects that range in performance in terms of quality and runtime. This paper demonstrates how software solutions can be deployed in a sensor that are both portable and interchangeable by leveraging open standards.
This presentation will describe how SOSA™ Aligned VPX modules and backplanes can be used to achieve Modular Open System Architecture (MOSA) objectives for RF High Performance and Embedded Compute (RF HPEC) systems. The presentation will describe a small set of SOSA Aligned RF and GPU-based VPX modules and backplanes and show how they can be used to create a plethora of system implementations, from a 32 channel RF transceiver system, to a 100 TFLOP HPEC system, with many possible combinations balancing the RF and GPGPU performance requirements needed for specific sensor applications.
This paper speaks to the transition towards the SOSA™ CMOSS architecture and how the Sensor Open System Architecture™ (SOSA) and C4ISR/EW Modular Open Suite of Standards (CMOSS) has enabled QRC Technologies to work with other vendors, products, and support the end-use customer in a variety of missions. The paper also briefly explores the benefits of allowing intraoperability between plug in cards in order to allow a wider adaptation of the standard.
QRC Technologies, a Parsons Company, produces a line of products specific to multi-mission, Signals Intelligence (SIGINT)/Electronic Warfare (EW) operations such as RF survey, capture and reconstruction.
The FACE™ technical approach tackles barriers to software modularity, portability, and interoperability by defining a reference architecture and employing design principles to enhance software portability required by the Department of Defense (DoD) Modular Open System Architecture (MOSA) strategies. To meet these objectives, the FACE Technical Standard uses a standardized architecture describing a conceptual breakdown of functionality, called the FACE Reference Architecture. The Transport Services Segment (TSS) provides the communication services within the FACE Reference Architecture and is a key enabler to portability and reuse of FACE Portable Component Segment (PCS) and Platform Specific Services Segment (PSSS) Units of Conformance (UoCs). The primary goal of the TSS is to optimize portability of PCS/PSSS applications by abstracting how messages are packaged and delivered between them. However, this primary goal may impact portability and reuse of the TSS itself and makes TSS portability a secondary goal that may not be achieved. This paper describes the role of the TSS in system design, its differences from the Input Output Services Segment (IOSS), and how the different Transport Services (TS) features can be applied to address common issues in system design. The primary audience for this paper are system integrators and TSS UoC developers. However, it can provide valuable insight to PCS and PSSS UoC developers as well, regarding expectations for the transport segment.
