(1) The main principle behind the single-frequency GNSS positioning local ionospheric mitigation concept, described in this paper, is a more accurate representation of the state of the ionosphere on a local scale. This is primarily achieved through the long-term and short-term, adjusted CCIR files … Web8 apr. 2024 · The switch values oscillated over time and reflected that individual satellites were considered outliers (subject to multipath effects) at some points in time, but treated as inliers at other times. Result 8.4. The proposed scheme for a robust back-end for SLAM has been successfully ported to the domain of GNSS-based localization.
