Research on the Update Method of Attitude Quaternion for Strapdown Inertial Navigation [PDF]
IEEE Access, 2021 In the strapdown inertial navigation system, the accuracy of the solving attitude and position is closely related to the quaternion update algorithm. For this reason, what method is used to update the quaternion has become an important project. At present, the primary method is to update the quaternion by solving the equivalent rotation vector.

Integrated Navigation Method of Aerospace Vehicle Based on Rank Statistics
International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023 The large dynamic and high‐speed flight of aerospace vehicle will bring unpredictable conditions to its navigation system, resulting in that its system random noise probability distribution will no longer meet the preconditions of Gaussian distribution preset by the existing filter algorithm, thus reducing the accuracy of the navigation system.
