In order to realize large airspace transfer orbitaltrajectory of an anti-ship missile, a 3-dimensional virtual target's proportional navigation guidance (PNG) law is proposed.
The most efficient launch trajectory is due east from a launch site, which places the satellite into an orbital inclination equal to the latitude of the launch site.
最有效的发射轨道应该在发射地点的东边,使卫星轨道倾度与发射点纬度相等。

Under a Lagrange coordinate system the trajectory of particles was tracked by the use of a random orbital method.
