All - Sorry for the off topic question but... I am looking at a number of sun synch satellites and wonder how to determine their local solar time at ascending node crossing. I looked at a book by Dave Vallado and also one by Bong Wie and do understand a lot more about these orbits but they did not have a way to characterize the orbits (that I recognized). Specifically: NOAA-19 is in a plane; NOAA-18, Cosmic Background Explorer, and SAC-D/Aquarius are in a different plane. So NOAA-18 and SAC-D/Aquarius are nearly co-planar (right now). Landsat-8 and NOAA-16 are nearly coplanar in a different plane. I think that some of them can be characterized by the solar time when they cross the ascending node. I looked at several NOAA web pages, etc (even Gunter's page) and do not see where it says if they are supposed to be in a particular plane and if so - which. Can anyone help answer this somewhat random question? Am I missing something simple?
