编程仿真连续小推力实现GTO到GEO的三阶段转移过程，其中推力器的推力大小为0.8N，轨道机动的起始点为GTO的远地点。GTO轨道的升交点赤经为0度，近地点角距为90度。 GTO轨道： ph:185km，ah：35786km，i：28.5°，GEO轨道：h：35786km，i：0°。 卫星质量为6600kg，从GTO到GEO，采用5000s的推力器。取地球半径为6378km，g取值为9.8m/s^2(The three stage transfer process from GTO to GEO is realized by simulation and continuous small thrust. The thrust of the thruster is 0.8N, and the starting point of orbital maneuver is the apogee of GTO. GTO orbit RAAN is 0 degrees, 90 degrees for the argument of perigee. GTO orbit: ph:185km, ah:35786km, i:28.5, GEO orbit: h:35786km, i:0. The mass of the satellite is 6600kg, from GTO to GEO, using the 5000S thruster. The radius of the earth is 6378km, and the value of G is 9.8m/s^2)
