通过月球近旁转向 ,可以改变航天器的对地速度大小和方向。借助圆锥曲线拼接法可以对月球近旁转向问题进行初步分析。研究表明 :利用月球近旁转向技术发射地球静止卫星和逆向卫星可以节省速度增量 ,发射场的纬度越高 ,节省的速度增量越多。 Through the moon near the steering, you can change the spacecraft’s ground speed and direction. By means of the conic splicing method, a preliminary analysis of the lunar near-turn problem can be carried out. The research shows that the use of lunar near-steerable technology to launch geostationary and reverse satellites can save the speed increment. The higher the latitude of the transmitting field, the more the incremental speed savings.
