Flush Foot Posted April 14, 2023 Share Posted April 14, 2023 KSP 2 v0.1.2.0 Win10 22H2 5900X CPU 48GB DDR4 3200MHz RAM TUF RTX 3080 10GB From my Reddit post: Does anyone else think the "Manoeuvre-marker" is incorrect? [or just different from KSP 1?] What I mean by my post is this (and I will get got a video up later tonight to demonstrate my point): If I have a manoeuvre that is moderately 'normal/anti-normal' or 'radial in/out' [so not strictly prograde/retrograde] and I run the burn at 1x speed with SAS holding the manoeuvre all along, my full-duration burn has an appreciably different result than was planned, and the node/marker moves dramatically during the burn [this is most evident to me with normal/anti-normal inclination-matching burns]. The best I can figure is that the marker and burn are programmed to be [for example] 15-degrees to the normal of prograde, but the marker then continues to be that 15-degrees off prograde, even as prograde moves-normal. If I use SAS to marker-lock and then enter time-warp [no changes in orientation] or switch to the orientation-lock instead of the marker, the burn does basically what I want/expect it to do. In KSP 1, I know it 'assumed' you were dumping all velocity into the orbit in an instant, but the marker only moved around in response to off-nominal thrust, leaving you with a decently close match, most of the time. Am I hallucinating or other-thinking this, or have others noticed the same thing? [I've noticed this ***certainly*** since Patch 1 (v0.1.1.0), but I think even since launch (v0.1.0).] [<Long> video! Cliff notes: 28.2-incl.+raised Ap planned and Normal\/Manoeuvre-marker burns yielded 30.8-incl. and nearly-circular orbits while locked on initial marker gave planned orbit.] Link to comment Share on other sites More sharing options...
Flush Foot Posted April 14, 2023 Author Share Posted April 14, 2023 I can think of two solutions to this: • Manoeuvre planner applies inputs in the same way the Manoeuvre node will respond (like where pulling up on Normal marker plans an all-normal burn even as Normal moves, causing the planned orbit to match what a full-duration Manoeuvre-hold burn provides) though this will be challenging when time-warping through a weeks-long interstellar burn without ‘course-correction’ • Manoeuvre planner’s predicted path is what the Manoeuvre node-marker points at, possibly adjusting course slightly if any off-axis thrusting takes the craft off the projected course (KSP 1’s manoeuvre-hold/marker behaves basically this way) Link to comment Share on other sites More sharing options...
