Design and Key Techniques Analysis of a Navigational Two-dimension Trajectory Correction Fuze

We present a navigational two-dimension(2D) trajectory correction fuze(TCF) after a review on the existing 2D trajectory correction technologies.In this paper,the operation principle of the navigational 2D TCF and its key techniques,including GPS/MIMU based navigation,the canard-controlled approach,the fuze module despinning with a spin stabilized projectile,and so on are analyzed.Finally,the methods for design,modeling and simulation of the TCF are studied.The content in this paper provides references for the further study on 2D TCF.
