So, this rocket can reach 300km PE orbit circularization when it is set at an higher orbital altitude than 300 km AP and PE, the problem though is that it can't reach the exact eccentricity of 0.02-0.04, it always goes overboard with the GCRC, I have been trying to fidget with it a lot, but nothing seem to work? Do I have to redesign the kickstage or something? My most current test was with PVG parameters being set to try to reach a 300km AP and PE, but that didn't really work out, though I did circularize, it was both at a bigger altitude and a lower PE than 300 km. Honestly I don't know if the contract always required the PE of 300 km, since I remember this being easier in 1.8.1, but I guess the contract got an update at some point?

Sun synchronous orbits (SSO) use the oblateness of the earth to have a constant rate of change of their longitude of the ascending node. If that rate of change is 360Β°/year, the orbit's normal keeps pointing approximatey to the sun. High inclination orbits are better for this, since this keeps the Earth out of the way most of the time and enables constant thermal environment and power for the solar cells. The rate of change o the longitude of the ascending node depends on the orbit inclination and radius. this somewhat limits the possible orbits.
However, one thing I do not understand. I always hear that SSOs are all retrograde but never an explanation for this. Why is that the case? Surely the rotation of the Earth does not influence the precession of the nodes - or does it? Or is there another reason for this?
Quick question, I picked up the SSO contract and was wondering how to know what my apogee height would need to be to have an eccentricity of 0.03 with my periapsis ~320km?
Hi everyone, I just made a video covering sun synchronous orbits, I figured people in this subreddit would be interested. I'm super open to feedback, let me know what you think

Saw this contract pop up in the latest version of RP0, had no idea what a sun-sync orbit was and IMO the description is a little vague, so did some googling on it.
That made it clear what they are, but the orbital params still seem kind of vague...
Just Pe > 300km, eccentricity 0.02 - 0.04 and inclination above 95 degrees. Is that really all that's required? And would that genuinely result in an orbit that precedes annually IRL? (I'm assuming precession isn't actually modelled in RSS...)
Edit: inspiration
Let's ignore the effects of deceleration for now, and just say whatever continent the sun is over right now, that day does not end. How long before the light side of Earth is completely scorched, and how long before the Dark side is frozen over? What would the weather be like at the Edge - would it be livable?
I recently got the Remote Tech mod among a few others, which have finally given me purpose to use satellites. I have a space station in geo-synchronous orbit with kerbal, but that got me thinking, what about sun-synchronous orbit? How would I put a satellite in such an orbit that would constantly be between the sun and Kerbin, is that even possible?
Edit: upon further thinking that is probably not really possible, so the next best thing would probably be an orbit in such a way that it has constant sunlight, never getting stuck in kerbin's shadow
Complete novice - am just looking at SSOs and trying to figure out how the final orbital inclination is determined. Let's say you launched from a coastline that had access to almost but not quite SSO inclination, like 94 degrees instead of 98.7 degrees. How do you insert to a true precessing SSO? Are you stuck to what you can physically target from that launch site, or is there some other trick? Can't find anything that helps me online, if you have a reference happy to do some reading!
I don't want a straight out answer, but I would love some tips.
I have been trying to teach myself astrodynamics for a couple of years now, as time and motivation permit, to answer this question and because of kerbal space program.
Here is the full question: How many degrees of longitude will a satellite cross with respect to the surface, if the satellite is in an eccentric equatorial synchronous orbit (not a stationary orbit)?
I am less interested in the actual answer than i am in the process.
i know its possible but i cant do it
i got my craft to 357947m so i got a synchronous but how do i lower my peri without de syncing
(please explain it in a way my smol brain can understand)
Hello everyone! I've made some research on this matter but I didn't find satisfactory answer, maybe because I'm not very good at mathematical problems related to physics. I was trying to calculate synchronous orbit of a celestial body, I used some web calculator to get the result but it was negative. To check if it's calculating correctly I've done the math for the Earth and the the result was more or less correct. That's makes me wonder if every celestial body has synchronous orbit? My body was actually a small moon that is tidaly locked to it's planet. Can You tell me if a synchronous orbit exist for that kind of celestial bodies? If You need I can give You everything You could need to answer the question. Best regards
