Frames configuration is, by default, relatively simple as it has been considered the best ratio between precision and CPU time. Anyway, it is possible to make it more complex. Nevertheless, be careful about the EOP corrections as it needs some data provided by [PATRIUS_DATASET] (included in the jar). So, if the data for a given epoch are not available, the propagation will exit with an error status.
Note : in V11.0, by default configuration is the complex (factory) one.
The following diagram explains the links between all considered frames.
In the table below, we can see an example of precision versus CPU time depending on the frames configuration and for a 30 days LEO propagation:
| Case | Corrections | Max position error (m) | Max velocity error (m/s) | CPU time (s) |
