wow...2 great recommendations. thanks
On the first one you gave me do you know what it means in the documentation by :
Limitations:
-Only two-body elements are considered
what is example of a "two-body element" ?
The two bodies are the
minor body
doing the orbiting and the
major body
being orbited.
Examples would be your spacecraft (minor) orbiting earth (major), the moon (minor) orbiting the earth (major) and the earth (minor) orbiting the sun (major).
In a two-body system, the trajectory of the minor about the major will be either be a circle, an ellipse, a parabola, a hyperbola, or a straight line. These are the only shapes that Videnie can show, hence "-Only two-body elements are considered"
An example of what Videnie can NOT show is a full Earth-Moon trajectory. This is a
three body system with both the Earth and Moon acting as major bodies at some point and your craft acting as the third, minor body. Trajectories can be sort of s-shaped, but Videnie may just show a changing ellipse around the earth, and won't show your trajectory around the moon until you get very close.
