There is the basic text (which you’ve very likely got, but I’ll not assume), which contains references to older papers of interest: http://celestrak.com/publications/AIAA/2006-6753/ with the referenced software in multiple languages at: http://celestrak.com/software/vallado-sw.php There is a Java SGP4 implementation deep inside Orekit: https://www.orekit.org For Python, just search for "Python SGP" and you’ll find it ! All the implementations derive from the one in the 2006 paper, referenced first above. > On Jul 31, 2018, at 2:14 AM, Jorge Pérez via Seesat-l <seesat-l_at_satobs.org> wrote: > > Thank you for the clarification!
