嫦娥三号成功发射并抵达月球轨道。其着陆轨道设计的基本要求:着陆准备轨道为近月点15km,远月点100km的椭圆形轨道。文章建立数学模型解决着陆准备轨道近月点和远月点的位置,以及嫦娥三号相应速度的大小与方向。
Chang’e III successfully launched and arrived at the lunar orbit. The basic requirements of its landing orbit design: landing preparation track for the recent 15km point, 100km long moon point elliptical orbit. The paper establishes a mathematical model to solve the position of the landing preparation orbit near the moon and the far moon and the corresponding speed and size of Chang’e III.
