Just curious.

I have a ship in orbit around Kerbin with only a 400m difference between apo- and periapsis and the two tags are just twitching back and forth slightly. Just wondering is there is any way to keep them still.

[CrazedGunman502]

It's going to do that if you have a perfect orbit

[rpayne88]

Time warp. Other than that, I believe it is due to floating point errors, making it impossible to stop while physics is simulating the vessel's trajectory. Time warp puts it on rails and turns physics off.

You'll find that the closer you get pe and ap to the same hight, the more twichy they get.

Any forces applied to your craft will move them around including small sas corrections, try turning off the sas and you should see less twitching.

To completely stop the twitching you need to stop the physics simulations on your craft

by either time-warping or switching vessels to something outside loading range. (Think it's about 2km, unless it's modifyed by mods.)

There's no need to get a perfectly circular orbit in the first place. So to stop the markers from wobbling around, you just need to raise your apoapsis or periapsis by a few kilometers.

Yup...this is an old "feature" Although, my orbits are rarely THAT circluar!!

Think of it this way: if you did achieve a perfectly circular orbit, where would you draw the periapsis and apoapsis? Because every point in the orbit would qualify as both simultaneously.

Anyway, having a 0.5-1.0km difference in the two apsides should stabilize the markers. That's what I do, because I find the jittering completely distracting.

It's a bug in the game...essentially when your orbit circularises AP and Pe should disappear and be replaced with a circularised icon

It can be a pain when setting up a maneuver mode as the target marker jumps all around as well. Just a rounding error glitch to ignore.

SAS OFF makes smoother
