Question about the epoch of the orbit estimated

Hello everyone, in the NumericalOrbitDetermination example, the epoch of the orbit estimated is consistent with the initial orbit. Can I customize the epoch of the orbit estimated? How to achieve this? Thank you!

Hello @newWL,

You need to propagate first to the date you want and reset the orbit in the propagator builder.
However, know that if you use the same model and the same measurements this should provide the same results. So you can also propagate to the desired date after the estimation is done.
Also know that the closer (in time) your measurements batch is to your initial guess orbit, the faster the estimation will be (less propagation time).

Hope this helps,

Thank you so much, really helpful.
