<queqiao-> ⟨S​erina⟩ why do i get different periapsis depending on my reference frame?
<queqiao-> ⟨A​l2Me6⟩ Elaborate please
<queqiao-> ⟨A​l2Me6⟩ Elaborate please (which frames?) (edited)
<queqiao-> ⟨S​erina⟩ Which frames should i be using when trying to plot a interplanetary intercept
<queqiao-> ⟨A​l2Me6⟩ Sun-centred body-aligned, at least for getting an initial encounter.
<queqiao-> ⟨A​l2Me6⟩ I use body-centred inertial for fine-tuning
<queqiao-> ⟨S​erina⟩ for both plotting and maneuver?
<queqiao-> ⟨A​l2Me6⟩ Ejection should be ECI
<queqiao-> ⟨A​l2Me6⟩ Ejection burn should be ECI (edited)
<queqiao-> ⟨S​erina⟩ That doesn't give me a Venus Apo and Peri though
<queqiao-> ⟨l​pg⟩ (you pretty much always want the maneuver frame to be the frame you're going to be "in" while executing it)
<queqiao-> ⟨S​erina⟩ ❤️ and how about the plotting frame?
<queqiao-> ⟨l​pg⟩ what he said
<queqiao-> ⟨S​erina⟩ Thanks, that made it easier, also RIP i need a nearly 2 km/s plane change maneuver
<queqiao-> ⟨A​l2Me6⟩ o_O if you launched to the correct parking orbit you really shouldn't... Butcher has a script for that, and you can also try the version of TWP that was recently pinned to #ro-general
<queqiao-> ⟨S​erina⟩ I tried using that to get into the correct orbit, I did do my ejection burn three hours early though according to the thing but that shouldn't throw me off that much should it?
<queqiao-> ⟨S​erina⟩ i probably didn't plan my burn properly tho

<raptop> Is this why egg has been having bot problems? https://twitter.com/coastal8049/status/1431700090088042504
<queqiao-> ⟨e​gg⟩ (I think that orbiter is unrelated to 鹊桥)

<queqiao-> ⟨S​erina⟩ I figured out part of why my orbit thingy is off
<queqiao-> ⟨S​erina⟩ Orbital precession
<queqiao-> ⟨A​l2Me6⟩ Yep, you can’t wait for too long in your parking orbit.
<queqiao-> ⟨S​erina⟩ and depending on the inclination, the precession is even worse
<queqiao-> ⟨S​erina⟩ so every orbit you do, you gotta correct more
