Optimization Method of GNSS/INS Factor Graph Using Forward Tightly Coupled

Although Kalman filtering and factor graph optimization have been widely used in GNSS/INS integrated navigation, their positioning accuracy can degrade significantly in urban canyon environments because of satellite signal blockage, multipath effects, and non-line-of-sight errors. To improve robustness and accuracy, th...
