⟨ZombieZilla⟩ For a Sun Synchronous orbit around Earth, I want the orbit analyser to report a precession of 1°/d, correct?
<queqiao->
⟨Stonesmile⟩ Not really, it's slightly off from that. If you use the correct reference frame it should be 0° though
<queqiao->
⟨test_account⟩ Orbit analyzer should report the same values regarless of reference frame?
<queqiao->
⟨egg⟩ yeah.
<queqiao->
⟨egg⟩ The analyser doesn’t help you nicely with the properties of your orbit with respect to the Sun for now.
<queqiao->
⟨test_account⟩ But I suppose you can choose the sun-earth reference frame and the orbit will look like it does not precesses in this frame 🤔

⟨Stonesmile⟩ egg The new scrolling over numbers is really nice, 🧑🍳 💋
<queqiao->
⟨TheSquirrelPatrol⟩ So I recall not long ago, I could tell mechjeb to execute the next principia node, and sometimes it would engage warp, more often I would have to step into time warp myself, but then it would warp to the node and fire up correctly. Right now, it's refusing to go into time warp on it's own at all, and it usually drops out about 10 minutes before the node. Was there a change? Is there a mechjeb or principia setting...
<queqiao->
... somewhere I'm forgetting?
<queqiao->
⟨Stonesmile⟩ You could always use the Principia "warp to node" instead of the MJ version
<queqiao->
⟨egg⟩ FWIW I don’t think we’ve changed anything in that area.
<queqiao->
⟨TheSquirrelPatrol⟩ Honestly I would expect that to be a mechjeb difference, not Principia, but anyone who knows would be here. I wonder if I'm not using the dev brnach mechjeb this time, and if that's the difference
<queqiao->
⟨egg⟩ that sounds like a testable hypothesis
<queqiao->
⟨egg⟩ (FWIW lamont is out, so you won’t get an answer from the MJ side for a while)
<queqiao->
⟨Milly⟩ ⟪TheSquirrelPatrol⟫ Honestly I would expect that to be a […] ⮪ I'm using the dev branch of mechjeb, and I've noticed issues with the Next Principia Node too - it starting burns early or late, cutting them short or leaving the burn going too long, stuff like that
<queqiao->
⟨test_account⟩ "cutting them short or leaving the burn going too long" could be due to variance? Hard to believe MJ just randomly executes burns with a wrong time
<queqiao->
⟨test_account⟩ But starting early or late sounds really strange
<queqiao->
⟨Milly⟩ ⟪_whitenotifier-81d9⟫ [Principia] pleroy closed pull request […] ⮪ Is the only way of getting an updated version with this fix in before the end of the month to get all the Visual Studio stuff and build your own copy egg? Just because I have no idea how Visual Studio works, and the issue with the miscalculating burns is causing some major issues with some of my interplanetary probes and landers
<queqiao->
⟨egg⟩ If your issue involves burns starting late or early, that pull request isn’t going to fix them. This is specifically about some RCS with thruster layout variants being accounted for as some multiple of their real thrust.
<queqiao->
⟨egg⟩ Also, no, either you learn how to build things yourself (in which case you also get no support for your homemade build), or you use the release whenever it happens.
<queqiao->
⟨Milly⟩ ⟪egg⟫ Also, no, either you learn how to build […] ⮪ No worries then, and yea, it was the RCS thruster layout variant issue I was on about
