Get local orbital frame

Orekit Python Wrapper usage

Hey all!

I have a question about the local orbit frames. I couldn’t really find a tutorial or anything for this, so I thought it would be best to ask the question here.

Suppose I have the spacecraft states of an estimated state (from OD), a reference state, and the ± 3 sigma bounds of the estimated state (SCest, SCref, SCstd_pos, SCstd_neg).

I want to transform these to a local orbital frame (NTW for example). How would I do this?

Thanks in advance,

Niek

Hi there,

To change frames on covariances you want to use the class StateCovariance. It has a convertFrame method that works with LOFType. Check it out in the Java library’s tests.
