Hi, I think this is because when the satellite perigee is below 220 km, a simplified set of equations needs to be implemented which is not done by the pyorbital module. As the Starlink satellites are sometimes deployed at very low orbits during their flight, they can go below 220 km. A way around this would be to deselect all the satellites that go below this range or use a set of satellites that do not go below this range during their flight. Currently, I do not have the bandwidth to work on this, any contribution is welcome.
