In-Motion Alignment with MEMS-IMU Using Multilocal Linearization Detection

In-Motion Alignment with MEMS-IMU Using Multilocal Linearization Detection

In-motion alignment is a critical step in obtaining the initial state of an integrated navigation system. This article considers the in-motion initial alignment problem using the multilocal linearization detection method. In contrast to the OBA-based method, which fully relies on satellite signals t...
