Research on simulation teaching method of spacecraft orbital dynamics based on STK

In view of the strong theoretical and practical characteristics of the"spacecraft orbital dynamics"course,the simulation experimental teaching method based on STK(systems tool kit)is studied.The characteristics of the"spacecraft orbital dynamics"course are analyzed from the teaching objectives and content system,and the teaching reform ideas based on simulation scenario courseware and simulation experiment course design are put forward.The teaching mode of course teaching simulation courseware and experimental design based on STK is analyzed.Two course design topics of spacecraft orbital maneuver design and ground coverage analysis are extracted.For the classical Hohmann transfer orbit,a simulation example of the orbital maneuver design is presented based on STK/Astrogator.Teaching practice shows that this method is helpful for students to construct spatial logical thinking,understand complex theoretical problems and cultivate practical application ability,which effectively improves the teaching effect.
