UmbralRaptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is 🐇. We currently target 1.5.1, 1.6.1, and 1.7.x. <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…

wait, it only works in one direction
<discord->
Sir Mortimer. — hm. launching a geostationary satellite so that it ends up exactly where I want it to be is a problem in itself
<discord->
Damien. — in stock or rss?
<discord->
Sir Mortimer. — stock
<discord->
Sir Mortimer. — @DRVeyl no, that PR wasn't merged. Currently I'm just looking at how to implement a parameter that looks at all vessels and if they are within a given min. elevation above a waypoint. can't use most of the CC boilerplate for that.
<discord->
Sir Mortimer. — i was going to test a UHF transponder contract, TV coverage over the equator
<discord->
Sir Mortimer. — CC is bad at looking at all vessels.
<discord->
Damien. — what about it is difficult?
<discord->
Damien. — I know in RSS you have issues relating to egginess
<discord->
Sir Mortimer. — turns out you can't just punch in the numbers in the cheat menu, you have to navigate the sat there
<discord->
Damien. — ah
<discord->
Sir Mortimer. — also turns out that I really should add something that tells you how far off the target area you are
<discord->
lpg. — hyperedit doesn't work with principia
<discord->
siimav. — Apparently hyperedit can be made to work in principia by enabling Hack gravity from the cheat menu
<discord->
RurouniDonut. — So I just saw the new celestial plotting system now :D, is Mechjebs planner gonna become obsolete for interplanetary maneuvers 😮
<discord->
Damien. — never used MJ for anything except ascent crew
<egg|anbo|egg>
uh oh
<discord->
RurouniDonut. — I used it for interplanetary launch windows, people said it was more accurate then transfer window planner
<discord->
egg. — @Sir Mortimer
<discord->
egg. — > turns out you can't just punch in the numbers in the cheat menu, you have to navigate the sat there
<discord->
egg. — hack gravity doesn't work?
<discord->
RurouniDonut. — But it seems to use more deltav for captures then I expect .(
<discord->
DRVeyl. — Look elevation is a good mechanic, too, and pretty easy to get.
<discord->
DRVeyl. — @Sir Mortimer HyperEdit?
<discord->
egg. — you should be able to hack gravity to make principia ignore loaded vessels
<discord->
DRVeyl. — Contract configurator had a broken implementation for Great Circle Distance. Pap fixed it in an RO rebuild but don't know if it ever got PR'd
<egg|anbo|egg>
it was stuck and now it's regurgitating backlog
<discord->
DRVeyl. — But that's a good way to describe how far off from the ground point you are.
<discord->
DRVeyl. — And.... If you want an extension to model sufficient data rate to some exemplar ground terminal, hit me up in PM and I can work on a way to call RA for that.
<discord->
lpg. — I'll be damned.
<discord->
egg. — Note that their histories will be forgotten
<discord->
DRVeyl. — Reasonable.
<discord->
Falcon. — So does principia allow orbital planning once you unlock lvl 2 of the tracking station and mission control?
<discord->
lpg. — principia allow Flight Planning right off the bat
<discord->
lpg. — but won't be able to put a maneuver node on the navball until you have maneuver nodes unlocked
<discord->
Falcon. — Yup, that's all I needed to know! Thanks!
<discord->
Damien. — the link was to the french one
<discord->
Damien. — oh we don't have a principia guide, just a link to eggs? yeah I'll wait on spamming it up with youtube links then
<discord->
Butcher. — I regularly build unreal engine at work, it's pretty hefty.
<discord->
Butcher. — Mine goes from 2 ms in Manchester, to 90 ms first hop in the US, and 96 ms in Atlanta.
<discord->
Butcher. — Yes, Paris to NY by the looks of that.
<discord->
Butcher. — @Standecco Its not 20,000 km across the Atlantic.
<discord->
Butcher. — London to NY is ~5600 km
<discord->
Butcher. — True, but if we're talking stock exchanges, then those are the big two.
<discord->
Butcher. — But I suppose a contract for submarine cables isn't really KSP.
<discord->
Butcher. — ```Approximate round trip times in milli-seconds:
<discord->
Butcher. — Minimum = 102ms, Maximum = 103ms, Average = 102ms```
<discord->
Butcher. — Manchester
<discord->
Butcher. — Appalachian State University
<discord->
Butcher. — is what we're pinging, in NC.
<discord->
Butcher. — Beat you @Sir Mortimer
<discord->
Butcher. — @Sir Mortimer Might also be routing. You'll probably get a different cable acorss the atlantic than me.
<discord->
Butcher. — 2 ms to level3's local hub is pretty good here, but it's probably nearby.
<discord->
Butcher. — ``` 9 2 ms 2 ms 2 ms lag-102.bear1.manchesteruk2.level3.net [212.187.136.77]
<discord->
Butcher. — Manchester
<discord->
Butcher. — Seems it's down near the univeristy, that's not far.
<discord->
Butcher. — You can cut latency a lot by not using the public internet...
<discord->
Butcher. — 50 ms is a big ask for satellite comms.
<discord->
Butcher. — The people demand 4k.
<discord->
Butcher. — 1.7.3 does feel much different to 1.6.1 for RP-1.
<discord->
Butcher. — 1.7.3 doesn't feel much different to 1.6.1 for RP-1. (edited)
<discord->
Butcher. — I'm a bit busier than I was also - my hiatus was due to a job change, bit less time to do random stuff.
<discord->
Butcher. — TV, pfft. Isn't radio good enough?!
<discord->
Butcher. — Don't forget 36 bit HDR.
<discord->
Butcher. — There's some code in my github, I might dig it out.
<discord->
Butcher. — 😆
<discord->
Butcher. — @egg Not sure. I worked around it to some extent with stock manoeuvre nodes.
<discord->
egg. — hm
<discord->
egg. — Okay it's done regurgitating whatever backlog it had remembered
<discord->
egg. — @Sir Mortimer okay so the chapter "Errors and Error Corrections" of *Understanding Satellite Navigation* has everything we need to compute the position error from the pseudorange errors
<discord->
egg. — then we can probably abstract away the pseudorange errors as a function of the fanciness of the tech you plonk on the satellite (and maybe environmental effects), making things reasonably concrete
<discord->
egg. — Actually maybe it's better to look at Capderou (14.11), there are some dodgy things going on in the other one

<discord->
Damien. — gang de nouilles pourpres se lèvent
<discord->
egg. — Wait you're not pink anymore
<discord->
Damien. — too fabulous for such a serious discord server
<discord->
Damien. — had to tone it down
<discord->
Damien. — I still think there should be a role for principia users

egg. — @Damien A role for Principia devs
<discord->
Damien. — Now that's just being selfish
<discord->
egg. — well, there's another one (though I think he only ever lurked on here without making an account) :-p
<discord->
lpg. — it's not selfish, it's bait
<discord->
Damien. — Pull requests by principia users. What could go wrong
<UmbralRaptop>
git push -am "Adding parameters to fix the error in Mercury's perihelion precession"
<UmbralRaptop>
(I'm not sure if such a contribution would be accepted or rejected. Also, I wouldn't actually be able to write it)
<discord->
egg. — UmbralRaptop: in order for it to be accepted, it would have to come with a full redesign of the abstractions to deal with the inner product not being everywhere the same and all bases orthonormal (this is the same problem as the rotating-pulsating frame, just on a larger scale)
<discord->
egg. — Obviously we won't accept a pull request that does such a huge redesign in one block, so that would pretty much have to go through design discussions with us
<UmbralRaptop>
fair
<discord->
Damien. — @egg What made you call XCI that and not XCSF?
<discord->
Damien. — inertial isn't obvious to the layperson
<discord->
egg. — what do you mean by SF
<discord->
Damien. — Space fixed
<discord->
egg. — the usual term for that one is ECI
<discord->
egg. — and ECEF for the other one
<discord->
egg. — they're standard terms, so I followed that
<discord->
egg. — ECSA is just me making shit up
<discord->
egg. — EMB is sometimes EMR
<discord->
Damien. — I saw the other term in the capderou handbook
<discord->
Damien. — Just wondered
<discord->
lpg. — @egg that bug you encountered with hitting the ground, that wasn't a 1.8 issue... might it affect פרנקל by any chance?
<discord->
egg. — nono
<discord->
egg. — it's just at head, it's the last pull request by pleroy
<discord->
lpg. — ok. then something else made me explode when I reached mars surface at 1m/s
<discord->
egg. — that sounds unpleasant
<UmbralRaptop>
Highly exothermic reactions with surface perchlorates?
<discord->
egg. — logs?
<discord->
egg. — INFO log might have something (or maybe not)
<discord->
lpg. — I'll have a look, but I'll chalk it up to user error of some sort unless it happens again
