Eckstein-Hechler model generates orbits with wrong velocity
A large inconsistency exists in Eckstein-Hechler generated orbits up to 6.x versions.
The problem is that if the circular parameters produced by the
model are used to build an orbit considered to be osculating, the velocity deduced
from this orbit is inconsistent with the position evolution! This means the velocity
is not exactly the time derivative of the position.
The reason is that the model includes non-Keplerian effects but it does
not include a
corresponding circular/Cartesian conversion. As a consequence, all subsequent computation
involving velocity are wrong. This includes attitude modes like yaw compensation and Doppler
