An Agile Model-Based Test Strategy for Assured PNT Implementation

This paper presents an agile Model-Based Testing (aMBT) strategy to guide the rapid acquisition and implemen-tation of modernized Positioning, Navigation, and Timing (PNT) capabilities. Next-generation PNT services need to be secure and assured to support of Multi-Domain Operations (MDO). With aMBT the systems that use PNT can become more responsive to mission requirements. Positioning, Navigation, and Timing (PNT) services are deliv-ered by System of Systems (SoSs) that support Multi-Domain Operations. Because, PNT services span many constituent systems and components, a holistic strategy is needed to select technology options to support end-to-end capabilities by integrating system resources. To implement Assured PNT services, a strategy is needed to determine how to ensure that PNT data is available during military operations.
