Universal Software Assured Position, Navigation and Timing (USAPNT) Receiver

QuNav proposes to prototype and field test a Universal Software Assured Position, Navigation, and Timing (USAPNT) receiver. Our USAPNT receiver is reprogrammable, software-defined, operating on multi-GNSS multi-frequency signals, and capable of signals of opportunity (SOOP) fusion and spectrum and power management. By fusing data from multiple GNSS and SOOP signals at the signal-processing level and at the measurement level, the USAPNT receiver in Phase I has demonstrated the potential to maintain the PNT solution continuity and availability with spoofing protection and graceful degradation in GNSS-challenged and GNSSdenied environments. The receivers architecture is built around an innovative open-loop vector tracking approach with spoofing discrimination and all-in-view signal processing that is also capable of deep integration for those platforms where inertial sensors are available. Phase II prototype will consist of a single wide-band antenna, a software-reconfigurable channelized RF front-end and a special co-processor (SCP) that is packaged in a GRAM S/M form-factor. The SCP will host an FPGA-based GNSS and SOOP correlation engine and an embedded software module for baseband signal processing and navigation estimation. For Phase II, QuNav will team with Northrop Grumman Electronic Systems to leverage Northrop Grummans existing prototyping engines and facilitate technology transitioning to military users.
