QuNav was recently selected to receive two Phase II SBIR awards from US Army in order to develop GPS receiver augmentations that improve PNT resiliency under jamming and spoofing
GPS Interference Mitigation Module (GIMM) :
GIMM will be developed as an add-on to legacy GPS receivers used in Army systems. The technology will offer interference detection and mitigation services to legacy systems that are lacking such capabilities. For software-defined radio-based implementation of modernized navigation systems, GIMM will provide a standalone PNT solution with interference discrimination. With CRPA, spatial information of both jammers and spoofers will be determined via array signal processing and without requiring any specific platform maneuvers.
Universal Software Assured PNT (USAPNT):
The USAPNT technology enhances the PNT resiliency in contested signal environments by augmenting GPS receiver architecture with multiple Global Navigation Satellite Systems (GNSS) and radio-frequency signals of opportunity (SOOP). A critical step for USAPNT transitioning to Army PNT systems is to protect open-service multi-GNSS and SOOP signals against malicious acts such as spoofing. The Phase II effort will prototype and demonstrate a signal assurance mechanism.
QuNav wins Phase I SBIR contract from NAVAIR to develop vision-aided navigation mechanization for GPS-denied flights over the water.
