| Abstract: | After analyzing all kinds of the navigation method and development of reusable launch vehicles,we establish a trajectory model of re-entry,which is based on the dynamics function of shuttle re-entry,and present different integrated navigation method for different re-entry phase.By analyzing the characteristic and applicable area of navigation method,we discuss the navigation simulation result based on INS and INS/SAR by research the terminal area energy flight phase character,then present a method to improve reliability and independence of TAEM navigation. |
