Method and apparatus for determining close approaches for earth-fixed launch trajectories |
摘要 |
Determining suitable launch windows to avoid or minimize close approaches between a launch vehicle and orbiting objects. A method and apparatus is disclosed for minimizing close approaches between spacecraft and other objects in space during the launch and early deployment phase of their lifetime, by defining a launch window, utilizing filters to screen certain objects in space from consideration and identifying launch window blackout times to avoid close approaches with the remaining objects in space under consideration.
