There are different kinds of sun-synchronous orbits (SSO) that differ in their right ascension of the ascending node and are usually named after the local solar time at the ascending node (LTAN), e.g. 9h LTAN. I am trying to find information or statistics about how the SSO satellites (I am mainly interested in active satellites) are distributed in relation to LTAN, but I couldn't find anything so far. I am looking forward to any kind of advice, links and help!

  • $\begingroup$ Welcome to Space Stack Exchange. I was wondering what you mean by "in relation to LTAN for days". If you go to celestrak.com/NORAD/elements you can find lists of satellites with their orbit parameters, from which you can roughly estimate LTAN. $\endgroup$ – Puffin Nov 28 '20 at 21:52
  • $\begingroup$ Sorry, "for days" was a typo. It's supposed to be only "in relation to LTAN". I will definitely check out Celestrak. Thanks for the advice! $\endgroup$ – diamon Nov 29 '20 at 14:35
