There are many kinds of zero-cost transfer trajectories from L1 to round parking orbits, but the energy cost, time cost of different trajectories are also different.
从地月系L1点晕轨道向月球圆停泊轨道具有多种零消耗转移轨道,但不同轨道的能耗和转移时间等指标不尽相同;
The zero transfer point can be set arbitrarily by appropriately selecting transmitting periodic time T and number N, and it is advantageous to eliminate some interference in some frequency points.
适当选择发射周期T和周期数N就可以随意设置梳状滤波器的零传输点,有利于消除某些频率的干扰;
