Hi everyone, I'm somewhat new to SR2. I have some experience with space sims but I'm still trying to figure out the specifics. My question is, if I want to get a satellite into orbit, and I want to plan out my stages according to the necessary maneuvers (i.e, first stage getting up to 15km altitude and ending with a 45 degree pitch, then second stage getting my trajectory up to 100km, then third stage circularizing the orbit), does anyone know how I could figure that out?

I've read up a lot on and watched quite a few videos about delta-v budgeting for orbital maneuvers and things like that, and I understand and can use delta-v maps, but those just show the total amount needed for orbit, and I want to know how to split it up across the stages properly so my launch and orbit goes as smoothly as possible. If anyone could explain or link any resources explaining how I can use something like the vis-visa equation to figure that out, or if there's any formulas specifically for that I haven't found, or just tell me if I'm thinking about this all wrong and overcomplicating it, I would really appreciate it! :)

    I might be able to help you out but the answers are loose in a way because of the variables that were left in your question.
    First question which solar system stock or downloaded then it's which one did you download and now want to try launching from.
    Most players build and build and fly I say build it backwards and think of where it will end you'll need fuel probably Methalox, or maybe electric Ion engines. when you build down think of more power and longer burn time then the top section. The bottom or first is almost always Kerolox and solid boosters or methalox boosters on the sides try quads much more stable. Hope it helps you.

    there are alot of ways to go about it, but the engine throat size and nozzle length will change the performance at different atmosphere densities - large throat size and short nozzle length will perform better at sea level (higher air densities), and small throat size and a long nozzle length will perform better in vacuum - the sliders for "altitude" and "mach" in the "performance analyzer" for the engines will show how changing the settings effect the performance, and helps with tuning in the engines and stages
