1. IntroductionReliable and accurate position and orientation information plays a vital role in the autonomous navigation of land vehicles, e.g., unmanned agricultural machinery and self-driving cars [1,2]. Global navigation satellite systems (GNSSs) have become the default tool for land vehicle navigation, employing real-time kinematic technology to achieve centimeter-level positioning accuracy.
