<queqiao-> ⟨AgustinCaniglia⟩ egg all your 2023 updates are marked as 2022 in the ksp forums.
<queqiao-> ⟨AgustinCaniglia⟩ You might want to fix that because like me, there could be others that think you haven't updaed the mod since 2022
<queqiao-> ⟨AgustinCaniglia⟩ * updated
<queqiao-> ⟨AgustinCaniglia⟩ Unless you don't want to face the reality that we are indeed in 2023
<queqiao-> ⟨egg⟩ Fixed, thanks.
<queqiao-> ⟨egg⟩ I should do something about this OP, it is an unmaintainable mess.
<queqiao-> ⟨thunkii⟩ ⟪night_beast⟫ Man.. I'm going to have so many […] ⮪ https://youtu.be/UCMSDvp-n74 this helps explain stuff too
<queqiao-> ⟨patrikcath⟩ Oh, I just remembered something I was wondering about a while back.
<queqiao-> If you have a geostationary satellite it obviously stays above the same location on Earth. If you have a geosynchronous one with a non-zero inclination it wobbles up and down between two locations, how far they are depends on its inclination.
<queqiao-> What happens if you have a satellite in a geosynchronous altitude, but 90-degree inclination? Does it start behaving like a regular polar satellite or does it only move on one side of the planet? I think about this way too much
<queqiao-> ⟨thunkii⟩ big figure eight basically
<queqiao-> ⟨thunkii⟩ crosses the equator at the same point every 11h58m
<queqiao-> ⟨egg⟩ ⟪patrikcath⟫ Oh, I just remembered something I was […] ⮪ https://climserv.ipsl.polytechnique.fr/ixion-out/pmiqt4aanbb9gifafta35d76u7-7b65b37323194655cc75c3becdfeef3a.png
<queqiao-> ⟨egg⟩ (So, what thunkii wrote.)
<queqiao-> ⟨patrikcath⟩ Huh, that's pretty cool
<queqiao-> ⟨patrikcath⟩ Good way to get a lot of coverage with just one satellite I guess
<queqiao-> ⟨egg⟩ (which you look at in-game, though admittedly that requires starting KSP.)
<queqiao-> ⟨egg⟩ ⟪patrikcath⟫ Good way to get a lot of coverage with […] ⮪ If you care about both hemispheres equally and don’t need to be moving slowly with respect to the ground and are fine with being far, far, away, I guess you can use a constellation of a few of these. This is not a very common combination of requirements.
<queqiao-> ⟨egg⟩ (I need to get back to #σκοπός so we can instill a sense of what concerns go into orbit design into people…)
<queqiao-> ⟨thunkii⟩ as inclination goes to 180 degrees, the figure eight just gets bigger until it wraps twice around the equator
<queqiao-> ⟨egg⟩ (like this.)
<queqiao-> ⟨egg⟩ (figures generated with https://climserv.ipsl.polytechnique.fr/ixion/, hacking the TLEs from some IGSO 北斗 satellite into the desired inclinations.)
<queqiao-> ⟨thunkii⟩ thank you!

<queqiao-> ⟨Quattro rumbass⟩ anyone care to explain to me how you "get to" lagrange points
<queqiao-> ⟨Butcher⟩ Fly in the right direction.
<queqiao-> ⟨Butcher⟩ When you get there, stop. The trick is knowing the right direction.
<queqiao-> ⟨Soviet Onion⟩ ⟪Quattro rumbass⟫ anyone care to explain to me how you […] ⮪ play around with the trajectory and see if you can get into an "orbit" when going int he right direction as Butcher said
<queqiao-> ⟨the rocket science kid⟩ the new rotating pulsating frame may also help with determining if you’re there yet
<queqiao-> ⟨pEdro⟩ ⟪Quattro rumbass⟫ anyone care to explain to me how you […] ⮪ when the line wiggles its way into a new direction, its likely near a lagrange point

<queqiao-> ⟨Quattro rumbass⟩ is my vessel's trajectory passing through a lagrange point in this photo?
<queqiao-> ⟨pEdro⟩ havent player around with the new principia features yet, but the x should mark it iirc
<queqiao-> ⟨pEdro⟩ you might be coming in too hot
<queqiao-> ⟨Quattro rumbass⟩ too fast?
<queqiao-> ⟨pEdro⟩ a bit
<queqiao-> ⟨pEdro⟩ ⟪Quattro rumbass⟫ is my vessel's trajectory passing […] ⮪ straight to the left is the sun, right ?
<queqiao-> ⟨Quattro rumbass⟩ the sun is to the "right" to the "left" is nothing
<queqiao-> ⟨pEdro⟩ good, theres a point both directions
<queqiao-> ⟨Damien⟩ ⟪Quattro rumbass⟫ is my vessel's trajectory passing […] ⮪ Yeah you're passing through the x on the left which I believe is the sun-earth L2 point. You need to get to that point without moving away from it so you need very little velocity as you enter it, or do a deceleration burn to capture into it

<queqiao-> ⟨Damien⟩ For sun-earth l-points I generally eject to a trajectory that just about reaches the point or just beyond it with some lateral velocity so I slide into an orbit easily. Often this means I eject slightly offset from the earth-sun line and then curve into the orbit at my ap when I'm moving slowly
<queqiao-> ⟨Damien⟩ Not sure if that's the best way but it works
<queqiao-> ⟨Quattro rumbass⟩ I think I sorta did it?
<queqiao-> ⟨Butcher⟩ Looks about right.
<queqiao-> ⟨Butcher⟩ L2 points aren't super stable so you'll probably have to do corrections.
<queqiao-> ⟨Damien⟩ Yeah. About 1-2yrs in ESL
<queqiao-> ⟨Quattro rumbass⟩ yeah got about 283 days in it
<queqiao-> ⟨Quattro rumbass⟩ and only a minor correction is needed to stay "inside" right?
<queqiao-> ⟨Quattro rumbass⟩ this is really cool
<queqiao-> ⟨Damien⟩ ⟪Quattro rumbass⟫ and only a minor correction is needed […] ⮪ Very, very small burns
<queqiao-> ⟨Damien⟩ Like 0.5% thrust rcs
<queqiao-> ⟨Damien⟩ The hard part is not overshooting corrections
<queqiao-> ⟨Quattro rumbass⟩ yeah that's fine
