A new extend file format for probe paths.

Actually the XYZ file contain only placement coordinates relative to the sun as reference object. The capability to define different references should be very helpful.

Description:

Having the capability of defining different references in the same XYZ file should allow to simulate almost perfectly the flybys of probes with moons. Another drawback is that should be possible to define a path for rovers on body surfaces.

A possible proposal should be something like this:

“Voyager”
{
  # Launch
  Reference “Earth/Sol”{
    [T pX pY pZ oX oY oZ]
    …
  }

  # Catapult 1
  Reference “Venus/sol”{
    [T pX pY pZ oX oY oZ]
    …
  }

  # Catapult 2
  Reference “Jupiter/sol”{
    [T pX pY pZ oX oY oZ]
    …
  }

  # Flyby 1
  Reference “Io/Jupiter/Sol”{
    [T pX pY pZ oX oY oZ]
    …
  }

  # flyby 2
  Reference “Callisto/Jupiter/Sol”{
    [T pX pY pZ oX oY oZ]
    …
  }

Or something like this

The meaning of the symbols could be:

• T: Time;

• pX, pY, pZ: Position coordinates;

• oX, oY, oZ: Orientation coordinates;

Another drawback should be that all of these data should be inserted directly in the SSC file specifying the path data instead of the XYZ path file
