01:00 <discord-> R​urouniDonut. — What was your launch profile?

01:22 <discord-> n​eph. — direct polar ascent

01:24 <discord-> R​urouniDonut. — Ohhh

01:24 <discord-> R​urouniDonut. — Did you use a historical launch date?

02:36 <discord-> n​eph. — Nope, I had to calculate my own launch window

02:38 <discord-> R​urouniDonut. — How was that?

02:39 <discord-> R​urouniDonut. — I wanna find resources and stuff like that to help understand orbital dynamics

02:42 <discord-> n​eph. — Pain in the ass, mostly.

03:13 <discord-> R​urouniDonut. — What resources did you use?

03:14 <discord-> n​eph. — kos and about two weeks of irl time

03:15 <discord-> n​eph. — i'd like to say my dank math skills but to be honest just trial and error in KRASH was more time-efficient

03:15 <discord-> R​urouniDonut. — Jesus

03:15 <discord-> R​urouniDonut. — Idek where to start to do the math for that

03:16 <discord-> n​eph. — the math would be surmountable if it wasn't, well, principia

03:16 <discord-> R​urouniDonut. — I have no idea how to calculate most trajectories

03:17 <discord-> n​eph. — That said, my approach was simply: 1) reliably get a 385Mm earth apogee 2) reliably place my earth apogee in the plane of the moon 3) reliably time it so that the moon will be over my earth apogee/lunar ascending node when I am

03:18 <discord-> n​eph. — launching polar worked because it allowed me to compensate for the inherent plane difference with the latitude traversed between ascent and insertion into TLI

03:19 <discord-> n​eph. — launching polar worked because it allowed me to compensate for the inherent plane difference with the latitude traversed between the KSC and insertion into TLI (edited)

03:20 <discord-> n​eph. — Do note that this approach requires launching over the south pole, so you'll have to have your rocket be autonomous for nearly all the ascent. kOS helps here significantly.

03:20 <discord-> R​urouniDonut. — I have a lot of trouble getting on the same plane of the Moon for some reason when precession is not kind 😃

03:21 <discord-> n​eph. — again, kos helps since you can calc the relative plane difference in real time

03:22 <discord-> R​urouniDonut. — Cant have you KER or Mechjeb do that?

03:22 <discord-> n​eph. — maybe but on god I'm not going to figure out how

03:54 <discord-> R​urouniDonut. — Hmm

06:47 <discord-> S​ir Mortimer. — Wait

06:48 <discord-> S​ir Mortimer. — KER can guide rockets?

14:35 <discord-> S​tandecco. — jupiter's magnetic field (and its axis) isn't perpendicular to the orbital plane of its moons

14:35 <discord-> S​tandecco. — is this right?

14:42 <discord-> e​gg. — @Standecco that's not right, it looks like you don't have Principia

14:42 <discord-> S​tandecco. — I don't since it's a test install

14:42 <discord-> e​gg. — ah, then it's WAI

14:42 <discord-> S​tandecco. — I don't since it's a dev install (edited)

14:42 <discord-> e​gg. — no axial tilt in stock

14:43 <discord-> e​gg. — @Standecco but if you want to test @Sir Mortimer's work on tilting magnetic fields, you're going to need Principia :-p

14:44 <discord-> S​tandecco. — no way to have correct magnetic fields in stock then?

14:54 <discord-> e​gg. — not if you tilt the satellites correctly; and if you don't tilt the satellite correctly, the Δv numbers and manoeuvres will be wrong

14:55 <discord-> S​tandecco. — installed principia and jupiter is tilted, but it doesn't look right anyway

14:55 <discord-> e​gg. — @Standecco okay, now yell at @Sir Mortimer :-)

14:56 <discord-> S​tandecco. — @Sir Mortimer geomagnetic_offset doesn't work either

14:56 <discord-> S​ir Mortimer. — @Standecco I suppose you're not using the released version of 3.0.2 correct? because that doesn't have tilt

14:56 <discord-> S​ir Mortimer. — tilt was added after the last release

14:56 <discord-> S​tandecco. — my kerbalism folder is a junction from github

14:57 <discord-> e​gg. — oh doing that with directory junctions is clever

14:57 <discord-> S​tandecco. — if the binaries aren't updated in the master then that's it

14:57 <discord-> S​ir Mortimer. — compiling them right now

14:57 <discord-> S​ir Mortimer. — sec

14:58 <discord-> S​ir Mortimer. — pushed to master

17:15 <discord-> S​ir Mortimer. — that's a horseshoe, right?

17:20 <discord-> S​ir Mortimer. — i was more or less forced into that orbit. it's a cube sat without attitude control, and the only engine on it doesn't gimbal - which came as a nasty surprise.

17:39 <discord-> e​gg. — @Sir Mortimer is that the KCKF frame?

17:40 <discord-> e​gg. — looks like an eccentric semisynchronous orbit, a bit like молния

17:40 <discord-> S​ir Mortimer. — yes 😃

17:40 <discord-> S​ir Mortimer. — I'm just doing a low energy transfer to mun

17:41 <discord-> S​ir Mortimer. — principia is loads of fun 😛

17:43 <discord-> e​gg. — @Sir Mortimer if this is KCKF, the orbit doesn't seem to be doing anything particularly weird; it's just something like https://en.wikipedia.org/wiki/File:Molniya.jpg

17:44 <discord-> e​gg. — in KCI it should be a pretty normal ellipse

17:47 <discord-> S​ir Mortimer. — it is, but the KCI screenshot is way less cool 😄

17:51 <discord-> e​gg. — obviously

17:51 <discord-> S​ir Mortimer. — 9 bits/second to Kerbin

17:53 <discord-> e​gg. — and KCKF is interesting if you are doing things where the surface matters (telecom, GNSS, earth observation, etc.)

17:53 <discord-> S​ir Mortimer. — yep

17:53 <discord-> S​ir Mortimer. — btw I already started working on a contracts mod that interacts with kerbalism

17:54 <discord-> S​ir Mortimer. — it already controls the visibility of radiation belts. you have to cross the field boundaries with a Geiger counter a couple of times for it to become visible. not quite how the real thing works, but it's a fun approximation for the game

18:05 <discord-> e​gg. — interesting

18:05 <discord-> e​gg. — I'll have to keep poking at that design doc

18:35 <discord-> S​ir Mortimer. — I'm currently tossing ideas in my head regarding things I need to fix before I can require an experiment to be running on a vessel for a contract without polling the vessel state all the time.

18:35 <discord-> S​ir Mortimer. — when I have that, I can essentially create "have experiment X running" contract parameters. in combination with "be above location Y within a few degrees of elevation from the surface" you can do a lot of fun stuff

18:51 <discord-> S​ir Mortimer. — "There will be a sport event near location X. Provide uninterrupted Kerkom coverage over that location from $begin to $end.

18:51 <discord-> S​ir Mortimer. — "There will be a sport event near location X. Provide uninterrupted Kerkom coverage over that location from $begin to $end." (edited)

18:54 <discord-> S​ir Mortimer. — But the requirement really should check for the experiment to be running. Depending on what it is, that can be a problem on it's own: you need EC, connectivity, possibly other resources like coolant...

22:14 <discord-> r​sparkyc. — @Standecco @egg so, some more details regarding my performance issues in RSS. Did a stock+principia install, and put a vessel in LKO. Maxed out timewarp and noticed that it still ran smoothly. Turns out, the max stock timewarp is 1x10^5, however my realism overhaul install lets me crank it up to 6x10^6 (60 times faster than stock). Even 1 below max in RO is 1x10^6; an order of magnitude highe

22:30 <discord-> e​gg. — @rsparkyc one thing we have noticed is that it is stupidly slow if you set a long prediction (even though it should be fine now that the prediction is asynchronous), because the computation of the ascending/descending nodes is done very badly

22:30 <discord-> e​gg. — and we show the nodes in ECI since Fatou, so that made matters worse

22:36 <discord-> r​sparkyc. — ok, i can try lowering the prediction length when i'm just warping at the space center and see if that does it

22:37 <discord-> r​sparkyc. — i'll update the ticket with my findings

22:46 <discord-> M​ike. — Does that have an effect in the space center where no orbits or anything like that are shown?
