Unconventional Navigation Approaches Using Signals of Opportunity Phase II

Current navigation systems are heavily reliant on GPS for both commercial and military applications. While GPS provides high accuracy, it is subject to denial in a contested environment. Under this effort, NAVSYS shall deliver an alternative navigation (ALTNAV) solution that utilizes signals of opportunity (SoOP) from a combination of commercial and military space systems. This will heavily leverage prior work performed by NAVSYS to deliver PNT as a Service (PNTaaS) under contract to DARPA, Air Force, and Navy customers. Ā Under the Phase II effort, we shall integrate an ALTNAV Software Defined Radio into a commercial SATCOM terminal to provide the capability to broadcast a time synced ALTNAV modulated signal over existing commercial and military communication satellites.Ā Our ALTNAV technology allows these existing satellite communication signals to also serve as PNT signals. We shall also integrate an ALTNAV SDR to perform a live demonstration of the capability to provide SoOP updates from a combination of GEO and LEO satellites to enable precision navigation to continue on a hypersonic glide vehicle in the absence of GPS.
