DOI: 10.1109/access.2021.3096422
Abstract: The main challenges for integration between low-cost strap-down inertial navigation system (SINS) and global navigation satellite system (GNSS) are to manage the non-Gaussian measurement noises and to access the reliable measurements during GNSS outages. Therefore,… read more here.

DOI: 10.1109/tim.2025.3565028
Abstract: The standard extended Kalman filter (EKF) is widely used in integrated strapdown inertial navigation system and global navigation satellite system (SINS/GNSS). However, its state-space model, derived from traditional error definitions, leads to poor estimation consistency.… read more here.
