Patent number: 11578992Abstract: The present invention relates to a method for updating strapdown inertial navigation solutions based on a launch-centered earth-fixed (LCEF) frame (g frame). The present invention uses the g frame as a navigation reference frame of a medium-to-short-range surface-to-surface missile. This is beneficial to establish a relative relationship between the missile and the ground so as to keep the same missile parameters required by a missile control and guidance system. The calculation of a navigation algorithm in the g frame is moderate, which is suitable for an embedded system.Type: GrantFiled: April 23, 2020Date of Patent: February 14, 2023Assignee: NORTHWESTERN POLYTECHNICAL UNIVERSITYInventors: Kai Chen, Hanyan Sun, Hongyu Zhang, Mingxin Liu
