When using high eccentricity values the calculation is wrong. This image as ec = 0.5

This module should handle all orbit manipulation. The organization of this module isn't necessarily trivial, and I really need to think of a good way of handling this. The _constructors_ in `smd` wereā¦

Hi!,
I would like to create clones of a given comet, in order to study its orbital evolution from a statistical point of view. My PhD supervisor do that in Mercury, but would like to implement thā¦

Hi Dominic,
I am starting to evaluate the performance of the new USM propagators, but it would be nice to use the number of function evaluations (so also including discarded step sizes), instead oā¦

Hello,
I am trying to add the unified state model (USM7) to the set of Tudat propagators by following the wiki, but I get the following error:

I am trying to get the cartesian position and velocity vectors for each propagation step in my orbit. I generated the orbit with Keplerian elements.
According to the documentation I should be ableā¦

The Modified Equinoctical elements definition changes at 90 deg inclination for conversion from keplerian elements. This could pose a problem for polar orbit using the result of this conversion.
