I am an amateur astrophysics enthusiast trying to generate orbit data.

What I want to achieve: I want to be able to generate orbits while only considering effects of (J2, J3, atm drag, solar pressure etc) , separately. Also I want to generate orbits and transitions for maneuvers such as Hohmann, bielliptic.

I just want to collect data at different points during the orbit.

I am mostly looking for 2 body simulation, such as a satellite around a planet.

I am searching for a scriptable application in python

  • $\begingroup$ To find orbits I was just using oscelt routine. I was using it random epochs (as data points). I didn't make it clear in the question but I am using it for validation only. (I have edited the question) $\endgroup$

    $\begingroup$ I don't understand your question; what does "I am unable to find any way to use perturbation (such as J2)" mean?. SPICE is not intended to produce orbits; it's only intended to use data files that usually include any kind of perturbation. $\endgroup$

  • $\begingroup$ @AyushSuhane are you including a complete solar system, or do you just want one planet and the Sun (or one moon and a planet) in your universe? You're still not really describing the scope of the problem, but in the mean time, go ahead and update your question with all of these things you've mentioned and then we can clean up all these comments. $\endgroup$

  • $\begingroup$ @AyushSuhane In the mean time, here's how I use Python to calculate things but I think there will be better answers. I've added the Python tag to your question. $\endgroup$
