SketchUp ephemeris


#1

Hello,
Is someone know how ephemeris data work in SketchUp ?
Thank you for your help.


#2

Your question is rather vague.

Are you asking how to use SketchUp’s Geo-location and Solar tools?
OR
Are you asking how ephemeris data is calculated by SketchUp?

The latter has not been revealed.

Yes that’s it, I would like to know how ephemeris data is calculated.
Thank you for your response.

Earth image map data is bought and I would think they would do the same for orbital information for either man made objects or celestial bodies. I would suggest a net search will give more information than you want. The physics behind the calculations can get very complex. Even if you want to get a precision Julian date I would not want to calculate by hand:)
