A factor graph optimization-based multi-GNSS real-time kinematic (FGO-RTK) framework is proposed to fill this gap, aiming to realize robust and precise positioning in urban canyons. In our method, a sliding window-based FGO estimator is designed, in which the continuously tracked double ...
Factor graph optimization (FGO) recently has attracted attention as an alternative to the extended Kalman filter (EKF) for GNSS-INS integration. This study evaluates both loosely and tightly coupled integrations of GNSS code pseudorange and INS measurements for real-time positioning, using both convent...
A novel architecture in which the Factor Graph Optimization (FGO) is hybrid with the Extended Kalman Filter (EKF) for tightly coupled GNSS/UWB integration with online Temporal calibration (FE-GUT). gnss uwb factor-graph extended-kalman-filter temporal-synchronization Updated Mar 8, 2024 C++ wvu...
Factor graph optimization (FGO) promotes the information fusion of such systems and achieves efficient real-time scalability; however, it cannot detect and process measurement outliers in real time, which limits the robustness of the system. To solve this problem, a novel robust FGO method based ...

factor graph optimizationincremental smoothingKalman or Kalman-related filtering methods are routinely applied in precise point positioning (PPP). However, in robot simultaneous localization and mapping (SLAM) systems, factor graph optimization (FGO) has proven advantages over filtering methods in recent ...
