Which method STK uses to compute Umbra or Penumbra time intervals?
someone knows in which way STK computes the eclipse times for a satellite?
I use a Matlab code taken from D.Vallado's library (ALGORITHM 34) but even if I use a PVT provided by STK (1 sec time step) ...

How can you construct the periodic orbits around libration points L1 and L2 in the circular restricted three-body problem and prove their existence?
Following up on a previous question about the classification of periodic orbits, how can they be constructed, especially the planar Lyapunov family, around libration points $L_1$ and $L_2$? And how ...
