<discord-> 王​小谦同学. — @egg Thanks, the reason why I created this is because that Principia was just introduced to Chinese KSP players, and there aren't really any guides, which makes a lot of people having a difficult time with Principia, for some weird reasons, I decided to do something like this.

<discord-> S​tandecco. — I think I got it
<discord-> S​tandecco. — I think I got it
<discord-> e​gg. — @Standecco nice, what's the Δv?
<discord-> e​gg. — @Standecco nice, what's the ∆𝑣? (edited)
<discord-> D​amien. — @Standecco nice. I reckon if you'd have started your burn a bit later (moving your ap closer to the mun or in front of it) you'd have captured on the 3rd loop
<discord-> S​tandecco. — @egg ~830
<discord-> S​tandecco. — @Damien you sure?
<discord-> S​tandecco. — I of course failed to execute it so now I'm back from start
<discord-> D​amien. — actually mine was behind it too
<discord-> D​amien. — maybe you needed a touch more dv then
<discord-> D​amien. — not that it matters
<discord-> D​amien. — you just phased over more orbits
<discord-> D​amien. — so you were probably more efficient than I was
<discord-> S​tandecco. — it didn't work though
<discord-> S​tandecco. — it's still the same problem
<discord-> S​tandecco. — if the maneuver requires .001 m/s accuracy, it's not a feasible plan
<discord-> D​amien. — what needed that?
<discord-> S​tandecco. — that flight path
<discord-> D​amien. — you only need to burn once to do what I did
<discord-> S​tandecco. — that's why I failed
<discord-> D​amien. — try using slightly more dv in your initial orbit and using the burn point to tweak things
<discord-> D​amien. — it shouldn't be that finicky
<discord-> e​gg. — @Damien 830 is very low
<discord-> e​gg. — so it may well be the case that @Standecco needs two passes to get a capture
<discord-> D​amien. — yeah that's what I'm thinking
<discord-> D​amien. — a few extra dv and it'd likely be a lot easier
<discord-> e​gg. — yeah, but it means more ∆𝑣
<discord-> D​amien. — he's never done it before, he just wants to do it 😃
<discord-> e​gg. — also, "a few ∆𝑣"? ∆𝑣 is not countable :-p
<discord-> D​amien. — go away egg 😛
<discord-> D​amien. — you know what I mean
<discord-> e​gg. — ah yes, a few yards per second of ∆𝑣,
<discord-> S​tandecco. — what should I aim for?
<discord-> D​amien. — a few extra METERS PER SECOND of dv and it'd likely be a lot easier (edited)
<discord-> e​gg. — 837ish is feasible
<discord-> D​amien. — yeah, mid 830's
<discord-> S​tandecco. — I like how specific he was
<discord-> S​tandecco. — I like how specific he is (edited)
<UmbralRaptor> a few eggstra furlongs per fortnight
<discord-> D​amien. — then play with the burn point to get a good capture
<discord-> D​amien. — you should be able to eyeball it and have a bit of wiggle room
<UmbralRaptor> spoils only require a few slugs of propellant
<discord-> S​tandecco. — oh, I never understood one thing: why are there 2 different frame of reference selectors for trajectory and flight planner?
<discord-> e​gg. — ah
<discord-> e​gg. — there's one selector per manoeuvre
<discord-> S​tandecco. — and why does the trajectory frame influence the flight plan frame?
<UmbralRaptor> s/spoils/should
<discord-> e​gg. — @Standecco so, you give your ∆𝑣 as a vector in the Frenet frame of your trajectory
<discord-> e​gg. — a component tangent, a component normal, a component binormal
<discord-> D​amien. — while we're on the subject of fucky reference frames, when aligning my molniya orbit I had to view it in ECEF but do my burns by using ECI pro/retro
<discord-> e​gg. — where e.g. tangent means "along the trajectory"
<discord-> D​amien. — (inb4 egg tells me off for using pro/retro)
<discord-> e​gg. — @Standecco but which way is "along the trajectory"?
<discord-> e​gg. — it depends which frame you draw the trajectory in (see also @Damien's example)
<discord-> e​gg. — so the manoeuvre frame determines which way is forward for the purposes of the burn
<discord-> e​gg. — but you can *look* at the flight plan in another frame
<discord-> e​gg. — that's the plotting frame
<discord-> e​gg. — @Standecco does that make some sense
<discord-> S​tandecco. — it makes perfect sense
<discord-> S​tandecco. — in stock the frame of reference is absolute, right?
<discord-> D​amien. — @Standecco in my example I needed to view my trajectory relative to earth's surface, but the burns I needed to do to tweak it were in earth centered inertial
<discord-> D​amien. — if I'd used the navball markers in ECEF mode I'd have fucked it up
<discord-> D​amien. — in fact I did initially
<discord-> S​tandecco. — meanwhile, I got it
<discord-> S​tandecco. — it was much easier this time
<discord-> D​amien. — 🔥 💯
<discord-> D​amien. — @Standecco now do you see the AN at the top left of your pic?
<discord-> D​amien. — make a maneuver there and play with it
<discord-> D​amien. — can't remember the direction but that's where squares are born
<discord-> S​tandecco. — top left left or top top left?
<discord-> S​tandecco. — top left left or top left top? (edited)
<discord-> e​gg. — > @Standecco in stock the frame of reference is absolute, right?
<discord-> e​gg. — Not sure what absolute means. In stock the reference frame is always <something> centred inertial
<discord-> e​gg. — then depending on the chosen patched conic mode, it's either all in the same <something>, or each in the <something> of the body for that conic
<discord-> D​amien. — @Standecco 9 o'clock on your chaotic mun orbit
<discord-> D​amien. — in front of it
<discord-> S​tandecco. — well, if the <something> is the same for all bodies, that's absolute
<discord-> e​gg. — conic modes https://forum.kerbalspaceprogram.com/index.php?/topic/11297-different-conic-drawing-modes/
<discord-> e​gg. — @Standecco I don't think you need to make up the word absolute here, it confuses things. for the example trajectory in that forum post: mode 3 is all KCI, mode 0 is KCI for one arc, then MCI, then back to ECI, mode 1 (default) and 2 are a bit odd, mode 4 is insane.
<discord-> e​gg. — mind you that's a 7-year-old forum post, maybe the default has changed or something
<discord-> S​tandecco. — might mode 4 be the one where the reference is the same for everything?
<discord-> e​gg. — no
<discord-> e​gg. — that's mode 0
<discord-> e​gg. — mode 4 is just insanity
<discord-> K​urgut. — @Standecco for square, Pe is about 2400 km the moon. one of the predicted revolution pass at the right place btw in your pic
<discord-> D​amien. — I've no idea what you're talking about with modes
<discord-> e​gg. — that's mode 3 (edited)
<discord-> K​urgut. — @Standecco for square, Pe is about 2400 km behind the moon. one of the predicted revolution pass at the right place btw in your pic (edited)
<discord-> K​urgut. — @Standecco for square, Pe is about 2400 km behind the mun. one of the predicted revolution pass at the right place btw in your pic (edited)
<discord-> D​amien. — oh conics
<discord-> D​amien. — I skipped that part of the convo
<discord-> K​urgut. — @Standecco for square, Pe is about 2400 km behind the mun. one of the predicted revolution passes at the right place btw in your pic (edited)
<discord-> S​tandecco. — but mode 4 must be relative to something
<discord-> S​tandecco. — I still have to circularize after this capture though, right? I can't get it stable enough
<discord-> D​amien. — yeah you do
<discord-> D​amien. — but you can pick the point that works best for you
<discord-> S​tandecco. — I also get an extremely flickering trajectory if I go over 1.64e4 steps, even with min tolerance
<discord-> D​amien. — welcome to principia
<discord-> D​amien. — where the frames make no sense and floating point errors turn it into a disco
<discord-> K​urgut. — maybe one your future pass jiggles with WTB and can't decide to escape or capture you
<discord-> D​amien. — <https://youtu.be/pNAFEgYkgDg?t=251>
<discord-> K​urgut. — ^
<discord-> K​urgut. — the music crescendo is well timed btw ^
<discord-> K​urgut. — just when things go crazy :p
<discord-> S​tandecco. — RCS would've been really useful here
<discord-> K​urgut. — no changelog for Fatou as we had for Fary ?😛
<discord-> D​amien. — yeah
<discord-> K​urgut. — yes ^
<discord-> D​amien. — RCS for lagrange stuff for sure
<discord-> D​amien. — at 0.5%
<discord-> D​amien. — and even then it's too much
<discord-> K​urgut. — yeh, add precise control too
<discord-> D​amien. — brb fitting hall thrusters as rcs
<discord-> S​tandecco. — interesting orbi
<discord-> S​tandecco. — interesting orbit (edited)
<discord-> S​tandecco. — I don't know how that works exactly
<discord-> D​amien. — flick through the other frames
<discord-> D​amien. — after all, this:
<discord-> D​amien. — is actually this:
<discord-> S​tandecco. — I could get a 11 m/s transfer
<discord-> D​amien. — nice
<discord-> S​tandecco. — I could get a 11 m/s capture (edited)
<discord-> S​tandecco. — mine is hearth shaped
<discord-> D​amien. — you been to the l-points yet?
<discord-> S​tandecco. — nope, not sure where they are
<discord-> D​amien. — see if you can turn one of the mun approaches into a nice l2 transfer burn
<discord-> D​amien. — swing past the mun in the direction opposite to kerbin while in mun barycentric
<discord-> D​amien. — with not too much velocity, and see if you can get the trajectory to loop back on itself
<discord-> D​amien. — hard to describe but you'll know it when it happens
<discord-> S​tandecco. — do I get any?
<discord-> S​tandecco. — it doesn't look like to me
<discord-> D​amien. — yeah I don't think any are lined up already, it's pretty fiddly tbh and I wouldn't know how to get there from where you are
<discord-> D​amien. — it's easy from kerbin
<discord-> D​amien. — the inclination you pass the moon in determines whether you hit L2 in a flat or inclined orbit
<discord-> D​amien. — if you go straight from kerbin equatorial and hit the moon the same it'll be a flat one
<discord-> S​tandecco. — I'll just land with this then

<discord-> K​obymaru. — doesn't have to be geostationary, but I want reasonable coverage with preferrably no station keeping
<discord-> K​obymaru. — Tundra & Molniya orbits are good, but I'd like something for lower attitudes too
<discord-> D​amien. — no network will be set and forget but geosync shouldn't be too bad
<discord-> D​amien. — not geostationary, but just sync
<discord-> D​amien. — depends how many you want to launch
<discord-> D​RVeyl. — Well, a batch of coplanar LEO satellites should be pretty set-and-forget. They should all perturb very similarly.
<discord-> K​obymaru. — > not geostationary, but just sync
<discord-> K​obymaru. —
<discord-> K​obymaru. — is that better than geostationary? is there maybe a magical inclination/eccentricity?
<discord-> K​obymaru. — > Well, a batch of coplanar LEO satellites should be pretty set-and-forget. They should all perturb very similarly.
<discord-> K​obymaru. —
<discord-> K​obymaru. — Well I had some at 3000km (not LEO but still low). They were evenly spaced out and now they're all on one side 😦
<discord-> D​amien. — @Kobymaru the moon will mess with your up/down position and the minor vs major axis of the equator will mess with it laterally
<discord-> D​amien. — so true geostationary is hard
<discord-> D​amien. — and needs constant stationkeeping
<discord-> D​amien. — this is one I did
<discord-> D​amien. — that's before egg explained the equatorial drift issue
<discord-> D​amien. — and I repositioned it to a stable longitude
<discord-> K​obymaru. — what's a stable longitude
<discord-> D​amien. — nothing you can really do about the up/down oscillation
<discord-> D​amien. — @Kobymaru imagine you're looking down on the earth from the north pole
<discord-> D​amien. — the equator isn't circular
<discord-> D​amien. — it's oval shaped
<discord-> D​amien. — satellites don't want to be near the long ends
<discord-> K​obymaru. — wait what
<discord-> D​amien. — so they oscillate around the narrow end
<discord-> K​obymaru. — I know the earth is an oblate spheroid, but I'd have to look at the equator edge on to see it. not from the north pole
<discord-> K​obymaru. — how is the equator not circular, where is the bulge
<discord-> D​amien. — if you look from the side, it has a bulge
<discord-> D​amien. — if you look from the top down, it also has a bulge
<discord-> K​obymaru. — the second one is news to me
<discord-> D​amien. — it was to me too
<discord-> K​obymaru. — So we went from Flat -> Sphere -> Oblate Spheroid -> Space Potato
<discord-> D​amien. — see my shitty diagram
<discord-> D​amien. — from top down on the earth
<discord-> K​obymaru. — I get it now
<discord-> D​amien. — the satellite is being pulled by the higher gravity at the major axis points
<discord-> D​amien. — and in doing so it oscillates around the minor axis
<discord-> K​obymaru. — As much as I like playing with Principia, the "Principia needs to be stock" people need to shut up
<discord-> D​amien. — agreed
<discord-> K​obymaru. — Because station keeping your satellites is not something that I would put onto the average KSP newbie
<discord-> D​amien. — that screenshot I posted with the oscillation was over KSC at 80.6°W
<discord-> D​amien. — very little oscillation
<discord-> D​amien. — apart from the north-south drift but can't help that
<discord-> D​amien. — the moon is a dick
<discord-> D​RVeyl. — "Well I had some at 3000km (not LEO but still low). They were evenly spaced out and now they're all on one side" -- and their periods were matched? They can still drift relative to one another, but I don't think drifting into a clump is a long-term result?
<discord-> D​amien. — sounds like bad periods tbh
<discord-> D​amien. — should have bought them some ice cream and a hot water bottle
<discord-> K​obymaru. — @DRVeyl
<discord-> K​obymaru. — > and their periods were matched?
<discord-> K​obymaru. —
<discord-> K​obymaru. — Yes, I matched them down to half a second. Maybe drifting into a clump isn't a long-term result, but de-syncing them is
<discord-> K​obymaru. — which will lead to clumps at one point or the other
<discord-> K​obymaru. — @Damien so there *are* magical latitudes? 105°W and 15°W?
<discord-> D​amien. — yes
<discord-> K​obymaru. — OK, that's something. Now the question is how to cover the rest of the earth 😉
<discord-> D​amien. — you could put satellites at the major axis too
<discord-> D​amien. — not completely stable but better than offset
<discord-> D​amien. — or just have the two and then some 45° inclined ones zipping about
<discord-> D​amien. — go nuts
<_whitenotifier-5dfc> [Principia] pleroy labeled issue #2185: Make Warp to Maneuver Node lead time tunable - https://git.io/fj0qg
<discord-> K​obymaru. — Yes but I'm lazy and don't want to keep launching them or do stationkeeping 😅
<discord-> D​amien. — just don't have commsats, fuck it
<discord-> D​amien. — DSN is all you need
<discord-> D​amien. — maybe stick a molniya or three
<discord-> D​amien. — that's it
<discord-> K​obymaru. — It's about the launches, it annoys me to not have connection if I do burns somewhere
<discord-> K​obymaru. — but yes, maybe some molniyas are the solution
<discord-> D​amien. — I love how my molniya's turned out
<discord-> K​obymaru. — how many do you have?
<discord-> K​obymaru. — both south and north pole?
<discord-> D​amien. — and yes I know I spelt them wrong
<discord-> D​amien. — already fixed
<discord-> D​amien. — they hand off to one another over russia
<discord-> D​amien. — perfect groundtrack
<discord-> K​obymaru. — Well as long as you don't spell them Молния, everything is wrong 😉
<discord-> D​amien. — yeah no
<discord-> D​amien. — get out
<discord-> D​amien. — 😛
<discord-> D​amien. — I was surprised at how they did the handover so well
<discord-> D​amien. — I didn't have to sync them
<discord-> D​amien. — just align the orbits so they have the same groundtrack
<discord-> D​amien. — lucky

<discord-> D​amien. — thought that'd be a quick mission but as mentioned, that's not the case
<discord-> D​amien. — turns out geostationary is hard
<discord-> D​amien. — terminator sunsync was fun too, especially when I thought it had broken but it was actually fine

<discord-> D​amien. — I thought it had precessed
<discord-> D​amien. — it hadn't
<discord-> D​amien. — well, I mean it does precess but I thought it moved relative to the sun
<discord-> D​amien. — timewarped to launch +1 year and it was fine
<discord-> K​obymaru. — pretty!
<discord-> D​amien. — yeah I love the way it looks
<discord-> D​amien. — looking forward to putting something like a radar altimeter in that orbit in Rp-1
<discord-> D​amien. — always has solar power

<discord-> S​tandecco. — but I was disappointed twice today
<discord-> S​tandecco. — first, when I noticed that there is no volume in the inventory mechanic
<discord-> K​obymaru. — OK, this is significantly more perturbation that I expected in 10 days
<discord-> S​tandecco. — and instead you only have 1 slot for kerbals, but that's a shit solution compared to KIS
<discord-> K​obymaru. — > first, when I noticed that there is no volume in the inventory mechanic
<discord-> K​obymaru. — Oh no
<discord-> S​tandecco. — the second time it was because of small hinges and their terrible strength, which I hope can be fixed by mods
<discord-> K​obymaru. — hmm
<discord-> K​obymaru. — that is a bit disappointing
<discord-> S​tandecco. — that perturbation is because of earth's oblateness in the vertical axis
<discord-> S​tandecco. — the one everyone thinks of when we say that earth isn't a sphere
<discord-> K​obymaru. — I keep underestimating these effects
<discord-> K​obymaru. — I thought "what's gonna happen in just 10 days?"
<discord-> K​obymaru. — well, night-time launch for my kerbals it is
<discord-> e​gg. — @Damien that 105°W GEO trajectory is really nice
<discord-> D​amien. — it is, thanks for the education
<discord-> e​gg. — We should probably have things in the wiki explaining these subtleties at some point

<discord-> D​amien. — that's crazy talk
<discord-> D​amien. — what would principia be if not 10% well documented mechanics and 90% unicorn magic
<discord-> e​gg. — haha
<discord-> e​gg. — btw, change log for the upcoming release https://github.com/mockingbirdnest/Principia/wiki/Change-Log#fatou
<discord-> e​gg. — @Standecco well, 1.7 was implemented mostly by completely ignoring the new features, so that made it easy
<discord-> e​gg. — which means that the bottom-left elements display will show osculating garbage
<discord-> S​tandecco. — that's fine by me
<discord-> D​amien. — egg for president
<discord-> D​amien. — ```The nodes of a trajectory with respect to the equator of the closest celestial are now displayed when the trajectory is "sufficiently close" to that celestial; this helps adjusting orbits with respect to the equator and addresses a longstanding feature request (#1841).```
<discord-> S​tandecco. — just have to wait until you get those ephemeris working
<discord-> e​gg. — ah you mean the orbit analysis stuff
<discord-> e​gg. — this is tricky
<discord-> D​amien. — btw @egg how can you not provide early access binaries for your favourite principia shitposters
<discord-> K​urgut. — 😛
<discord-> e​gg. — sure, if you can make the orbit of the moon shorter
<discord-> D​amien. — ok brb

<discord-> e​gg. — generally when it's in the morning we do it the day before
<discord-> e​gg. — because I'm not going to get up to forumpoast at 10 in the morning
<discord-> D​amien. — surely you need testers right? 😄
