A mounted-to-dismounted concept for opportunistic navigation using low-earth orbit (LEO) satellite internet signals for position, navigation, and timing provides robust relative positioning among all equipped forces in a theater. The proposed system provides navigation-quality observables from multiple satellite constellations in ASPN ICD-compliant messages within a pntOS compliant architecture based on the Army-funded, ground-break research of The University of Texas Radionavigation Lab (RNL). During Phase I, the functional and performance requirements for LEO-PNT will be derived based on an analytical framework and modeling and simulation together with processing of live-sky signals from Starlink and other constellations as they become available. These requirements will then be allocated to hardware and software architectures for both mounted and dismounted units. This work paves the way for a Phase II prototype that matures the LEO-PNT prototype currently being developed by RNL into a pntOS compliant plug-and-play sensor module that will be integrated with a Viper-based implementation.
