egg changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Germain. We currently target 1.8.1, 1.9.1, 1.10.1, and 1.11.0. <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly… | <egg> also 4e16 m * 2^-52 is uncomfortably large
<discord-> A​shnoom. — So, i am currently in a not-so-optimal transfer time to mars. But I was just testing the vessel itsel (KRASH)
<discord-> A​shnoom. —
<discord-> A​shnoom. — I wonder what a good steps/tolerance should be?
<discord-> A​shnoom. — (The first Pe encoutner to mars is at 307d with the current burn)
<discord-> A​shnoom. — changing the Tolerance however wildly changes the expected path that'll be taken
<discord-> A​shnoom. — I would expect a Tolerance of 1.0e0 would be quite accurate. But there is a ~40Mm differencee in Pe betwen 1.2e-4m and 1.0e0m
<discord-> e​gg. — a 120 μm tolerance seems maybe a bit excessive on an interplanetary trip
<discord-> e​gg. — if your trajectory massively changes with tiny changes in tolerance, it is probably unstable (highly dependent on initial conditions), and therefore any prediction is unusable (the tiniest mouse fart will throw you off course anyway)
<discord-> A​shnoom. — 250x250 at 24incl
<discord-> c​ptmiche. — So I have a question with the step and tolerance
<discord-> c​ptmiche. — Or more specifically, tolerance.
<discord-> c​ptmiche. — The precision of your trajectory is not dependent on your tolerance, correct?
<discord-> c​ptmiche. — Like, if I wanted to see for a brief moment *exactly* where my probe will go, I can set the tolerance to the minimum value for a few seconds?
<discord-> e​gg. — the precision of the prediction is dependent on the tolerance, the precision of the real thing that will really happen is unaffected by anything you do short of changing config files
<discord-> c​ptmiche. — Ok, so then its a good idea to turn it the tolerance to a very precise value when planning interplanetary maneuvers?
<discord-> c​ptmiche. — And set it relatively imprecise when doing generic broad stroke maneuvers?
<discord-> e​gg. — not really, because you will make your UI slow for nothing
<discord-> e​gg. — you should not set the tolerance to something more much more precise than what you can achieve
<discord-> e​gg. — (what that means in practice, I don’t know, this is something you will probably learn by experience, but I don’t actually play)
<discord-> e​gg. — but it doesn’t matter if the calculations are done to micron-level precision if your RCS can only control where you get to at a precision of a few kilometres
<discord-> P​aculino (ŝi/ri/she/they). — I thought you played a little
<discord-> P​aculino (ŝi/ri/she/they). — I thought you played a little (outside of testing and bug hunting) (edited)
<discord-> e​gg. — yes, sometimes I make supersonic planes
<discord-> e​gg. — typically with trim tanks 🇫🇷
<discord-> P​aculino (ŝi/ri/she/they). — So, cool paintjob concord?
<discord-> e​gg. — yeah, though sometimes I go with ramjets
<discord-> e​gg. — Mach 6 airliner best airliner

<discord-> §​κyℓαr ♀. — I really wish that FAR supported wave gliders, a wave glider passenger plane would be 👌
<_whitenotifier-8975> [Principia] Jayemby starred Principia - https://git.io/Jtsla
<discord-> K​erbinator. — well, supporting wave gliders needs probably a fucking nice design of geometric shockwave calculation
<discord-> K​erbinator. — workload may become daunting to avoid using CFD that is impossible to calculate in realtime
<discord-> K​erbinator. — if you have any ideas, doing on this
<discord-> K​erbinator. — as one approach maybe calculating the waves and get the wave surfaces
<discord-> K​erbinator. — and use refraction law to calculate the flow behind the wave cone
<discord-> K​erbinator. — as one approach maybe calculating the waves and get the wave cones (edited)
<discord-> K​erbinator. — however, waves are populated in a per-part basis, high partcount stock vessel with this may still fuck your PC
<discord-> s​iimav. — Uhh, watch your language

<discord-> A​shnoom. — reference frames to setup geostationary sats is quite nice!
<discord-> B​utcher. — Yes, geo and rendezvous are two things Principia makes easier imo.
<discord-> §​κyℓαr ♀. — Yeah, it could be just a rough approximation. A rough approximation of ground effect and wavegliders would be amazing
<discord-> A​shnoom. — Did take some getting used to though. Still not proficient. But, learning :-0

<discord-> e​gg. — I wouldn’t say it makes GEO easier given the whole longitudinal drift thing :-p
<discord-> e​gg. — but it certainly makes assessing synchronicity easier
<discord-> B​utcher. — Oh there is that. Getting there is easier, staying there...
<discord-> e​gg. — in fact now, with the orbit analyser, it should make assessing any recurrence of your choice easier
<discord-> B​utcher. — I am really starting to like the analyser
<discord-> e​gg. — (the analyser took a while to get some use, but it does seem that people are starting to look at it now—I have done some work recently to make it more accessible & visible with the one-line summary and the flight plan integration, too)
