  • Advanced Real-time Tightly Coupled GNSS/IMU Fusion

    Navigating dense urban environments remains one of the most significant hurdles for autonomous systems due to GNSS signal blockages, multipath effects, and rapidly changing satellite geometry. In our research paper, “Real-time tightly coupled GNSS and IMU integration via Factor Graph Optimization,” we present a robust solution to these challenges. While Factor Graph Optimization (FGO) is…

  • Real-time Loosely Coupled GNSS/IMU Integration

    , , , ,

    Accurate positioning, navigation, and timing (PNT) is fundamental to the operation of modern technologies and a key enabler of autonomous systems. A very important component of PNT is the Global Navigation Satellite System (GNSS) which ensures outdoor positioning. Modern research directions have pushed the performance of GNSS localization to new heights by fusing GNSS measurements…
