12:09 <discord-> S​tonesmile. — There are two latitudes that are stable, see https://en.wikipedia.org/wiki/Geostationary_orbit#Orbital_stability

12:10 <discord-> S​tonesmile. — There are two longitudes that are stable, see https://en.wikipedia.org/wiki/Geostationary_orbit#Orbital_stability (edited)

12:12 <discord-> J​essica. — hmmm

12:12 <discord-> J​essica. — This also happens to tell me what the delta V requirements usually are

12:12 <discord-> J​essica. — 2 m/s per year isn't too bad

12:13 <discord-> J​essica. — and if I deploy some of the relay network to those points, it should be quite nice

12:13 <discord-> J​essica. — hrmmmm

12:14 <discord-> S​tonesmile. — The ammount of dv required isn't the problem; having to perform the burn manually is

12:15 <discord-> S​tonesmile. — By that I mean that you have to switch to the vessel quite often

12:20 <discord-> J​essica. — I don't need it to be too precise

12:20 <discord-> J​essica. — Could probably get away with correcting it every year+

12:21 <discord-> S​tonesmile. — Placing two sats at the stable points could be enough to cover your needs, and wont need any corrections

12:23 <discord-> J​essica. — It's mostly to provide better coverage for data relay for stuff at low altitudes

14:02 <discord-> B​utcher. — I have a sat at one of the stable points, it picks up a bit of latitude wobble from the moon but largely takes care of itself.

17:14 <discord-> n​eamisis. — damn you guys are so smart! playing with n body physics and stuff

18:31 <discord-> D​amien. — I played with myself once. It was hard

18:36 <discord-> B​uilderbast. — Noice

19:32 <discord-> S​umguy. — in the year I was gone, 1) have nodes become any easier to use, 2) has any progress happened on station-keeping?

19:43 <discord-> S​tonesmile. — 1; yes, 2; no

19:49 <discord-> l​pg. — 1) marginally. MJ has grown a 'execute principia maneuver' feature, but for RO it's only occasionally usable. It doesn't take engine spool-up time into account

19:50 <discord-> S​tonesmile. — The planning of nodes has improved quite a bit in the past months

19:53 <discord-> l​pg. — that's true. the Rebase button is one of my new best friends

20:56 <discord-> s​martdummies. — The rebase button is a godsend. The MJ execute Principia node button is much less so. I understand the coding reasons for not accounting for engine spool up time but that makes very unhelpful for most engines. Perhaps a box to add a value in seconds of how early to start the burn? That would be easier I think and make it more useful. I already have to start the burns earlier as Principia also

21:07 <discord-> e​gg. — > the Rebase button is one of my new best friends

21:07 <discord-> e​gg. — Hooray, I’m useful! I’m having a wonderful time.

21:09 <discord-> S​tonesmile. — Good! Now to bring that down a bit; would it be possible to ad the option to select a event on the flight prediction (e.g. a Pe) and have the manouvre planner set that as the time?
