UmbralRaptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Fermat. We currently target 1.5.1, 1.6.1, and 1.7.2. <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…

keymaster. — I'm wondering since it looks like you are on at least 1.7.1, and I'm looking to upgrade from 1.3.1.

[Principia] eggrobin synchronize pull request #2264: Elements - https://git.io/fjQJx
<discord->
egg. — @Damien yes, but that's just an open-loop definition; you want to control that your orbit is actually sun-synchronous
<discord->
egg. — to do that, you should look at it over a year in the earth-centred, sun-aligned frame, and check that it doesn't move with respect to the sun (aside from small seasonal effects)
<discord->
egg. — Eventually the orbit analyser should help with that, once I'm done writing it
<discord->
Damien. — Yeah I remember that from when I did mine
<discord->
Damien. — Apart from the seasons it was perfectly aligned
<discord->
egg. — @Damien you might want to drop a screenshot to illustrate
<discord->
egg. — also we should probably have wiki pages for these kind of questions at some point (though the analyser will probably change how you do things quite a bit, so maybe wait until then)

RurouniDonut. — Sooo
<discord->
RurouniDonut. — Launch when the launchpad is on the border between day and night?
<discord->
egg. — a sun-synchronous orbit doesn't have to be crepuscular
<discord->
egg. — "sun-synchronous" describes how it (doesn't) move with respect to the sun, not where it is
<discord->
egg. — you can have one that has its ascending node at local noon and its descending node at local midnight
<discord->
neph. — God bless Landsat
<discord->
egg. — the most common choice is an ascending node near 22:30 local time, descending node near 10:30 local time, optimal for northern hemisphere observation
<discord->
lpg. — do launch on the border between day and night if you want perpetual light on your solar panels
