Session B6: PNT Open Systems Architecture 1

Department of the. Air Force PNT Reference Architecture Development
Delbert Champ, Headquarters Air Force A5/7; Matthew Kascak, Justin Malek, and Armen Kurdian, Booz Allen Hamilton
Date/Time: Thursday, Aug. 26, 8:55 a.m.

The ever-growing demand for Resilient Position, Navigation, and Timing (R-PNT) to facilitate the DoD’s global reach and execute with a high probability of mission success over time resulted in a great divergence in technical requirements and configuration management. With the recent emphasis placed on modular open systems approach (MOSA), open systems architecture (OSA), and interoperability (such as Combined / Joint All-Domain Command and Control), the architectural implementation of R-PNT within interconnected platforms, C5ISR, and weapon systems are becoming more critical. While performance requirements will continue to vary, how R-PNT is integrated and designed requires a standardized reference architecture to facilitate not only performance and technological improvement, but also logistics, sustainment, and support.
The Department of the Air Force (DAF) PNT Cross-Functional Team (CFT) within HAF A5/7, Air Force Futures, has the responsibility to continue to develop, refine, and expand the DAF PNT Reference Architecture (RA) that will guide, constrain, and inform the development of specific solution architectures for future upgrades and deployments of R-PNT systems. This effort follows similar work underway by both the Navy and Army which take into consideration the unique aspects of each Service. The DAF RA both leverages the work done by the other Services and goes into significant detail regarding PNT services, operations, and functions as well as identifying the parameters and messages needed to share data both within the integrated system, and with external consumers. The DAF RA reflects capabilities and goals and is compliant with the DAF PNT Initial Capabilities Document (ICD) and the DAF PNT Strategic Plan. Several viewpoints have been developed which reflect capabilities, resources, and operational/functional activities. In addition, several use cases which provide application of R-PNT within DAF operational mission sets such as electronic warfare, personnel recovery, and global strike were developed in conjunction with AF Futures, MAJCOMs, and SPoCs. The RA also incorporates Navigation Warfare with integrity monitoring, situational awareness, and anti-jam and anti-spoofing. The RA will provide the ‘super-set’ of all potential PNT sensor types and functions from which solution architectures can select from for a particular instantiation and instance architecture. The DAF PNT RA has created incremental developmental versions with a planned release for wider coordination in Fall 2021. This presentation will provide a preview of the DAF PNT RA concept, data products, and contents prior to wide stakeholder review.
