[0.25] Orbit Manipulator Series (Updated March 12 2014)

[Endersmens]

I had FAR, and since its Apopapsis was like 10 meters from the edge, it would've been going near escape velocity when it hit the Atmo...Something tells me it wouldn't have been completely captured.

[HoneyFox]

What about the Ion Engine message spam bug?

I havent seen you mention that you fixed that..

That cause at least 50% drop of frame rate.. for me.. (with only 2 parts, a command module, an ion engine)

Well, wifh FAR, lower than 30 means your gonna deorbit..

Higher than 30 means your gonna surf into space...

if Stock.. since drag is related to mass.. GG..

Ah, that spamming issue, I remember that I've fixed it some weeks ago and has uploaded to dropbox.

You can redownload the file in OP since dropbox won't change the link after i update a file.

[nothke]

Is there a chance the mod could be upgraded into a "difficulty" mod where there is decay above 70km on Kebrin, so that we difficulty lovers need to think about station keeping? =)

This is something I was requesting long time ago

[dlrk]

Is this working in 23.5?

[NathanKell]

Since the file was last changed 2 months ago (when it was created for .23.5) I'd say it does. :]

[dlrk]

Hmmm..debating whether to install this. Does the n-body implementation make usual flight planning and maneveour nodes useless?

Basically they are still useful to some extent, but you will need several mid-course correction burns for your transfer to either moons or planets.

[razorblade75]

good mod, but i have to report a problem. i point the ship prograde, and start the time warp. the ship keep accelerating, but start to slow drift away from prograde

[KerbMav]

I almost did not look into this thread for the title sounded like something like hyperedit/orbit-hacking - how wrong I was!

For me the atmosphere effects while on rails is The feature of this mod!

If you go elsewhere and leave it on-rail, the orbit won't change

Is this a general truth for KSP? If I switch my ship and time warp, I will really slip past infront of a moon while crossing its orbit as planned and not be dragged into its SOI out or nowhere?

Ship on rails (not controlled or >2.5km from controlled one) will continue its orbit undisturbed if atmosphere is not present or <0.01atm and disapperar (just like that) when atmosphere is >0.01atm. Thus on rails - either going by it's route unaffected or disappears, never strays.

$@#^%#@$!?!?!?

I installed this earlier this month and it showed up fine in my game in the toolbar in the Tracking Station under 32-bit. Today I noticed it was gone. I removed all the mods I had installed since. I removed everything except Squad, NASAMission, NBody, Toolbar and MM. I deleted and reinstalled NBody. I deleted and reinstalled Toolbar (including the settings file). I deleted and reinstalled the default Squad/NASAMission folders. So I don't know WTF to do now except post a log

Edit: well I still don't know what the hell went wrong, but when I reverted back to the pure stock install and entered the flight scene of a new save, I noticed the toolbar had available buttons for the NBody mod. When I reloaded all my mods and loaded up my original save game the atmo decay button still didn't show up in the Tracking Station nor offer me the option to show any of the buttons. But when I entered the flight scene and opened the visible buttons window in the toolbar all the NBody icons were there. I didn't select any, just closed the window and returned to the Tracking Station and now the atmo decay button is visible again, and I can see all the NBody buttons when I open the Visible Buttons menu on the toolbar.

Okay.

That's because your vessel will point to a static direction in inertia reference frame while it's orbiting the earth, which means the prograde direction keeps changing when orbiting around. You can either quit time-warp and readjust your direction at certain intervals or perhaps you can try a plugin made by someone else that will turn your ship even in time-warp.

lol, that title seems to be quite misleading.

SOI change will still happen if the vessel is in the SOI range of the moon. But if your time-warp rate is too high, the simulation's time step is not small enough to catch that very moment when your vessel gets into the SOI of moon, and in this case you will slip past it.

Ah, that might be because of a small glitch in my code: The OMS plugin system is initialized when you are entering the flight scene, so you might not be able to find the toolbar buttons for it before you get into flight scene for the first time. Once there, you will have the toolbar buttons always.

Edit: these three buttons are only useful in flight scene so I guess the glitch is not that critical.

[Drew Kerman]

So the issue, now that I've noticed it and have done a few game sessions, is that the toolbar icon will for some reason not show up in the Tracking Station unless I have first entered and exited the flight scene

[ymir9]

This is a very cool plug-in. I like the fact that the N-body calculations only affect the active vessel. Having to maintain the orbits of a dozen communication satellites would be a nightmare, with Mun's orbit being so low compared to the Earth-Moon system. But this system still lets me play around with loopy orbits, and worry about degrading orbits when flying low over the Mun.

I believe this might do what you're talking about.

it works with ksp .25 i believe

[NihilRex]

Anyone tested this with 0.90 yet?

[NonWonderDog]

Unfortunately it seems to have some bugs now. After launching into an elliptical orbit my ship ended up flying at a constant altitude, with the periapsis chasing me around Kerbin whenever I time warped.

Maybe it works better if you install Blizzy's toolbar as well, but I've been trying my hardest not to need it anymore.

[cpottinger]

I am only using the orbital decay portion of this mod. It seems to be working just fine with 0.90.

Perhaps NonWonderDog's problem is the toolbar - not sure. I am using Blizzy's toolbar and it is working just fine for me.

[KerbMav]

I hate to jump into cold water with mods.

HoneyFox is still active on the forums though.

[nilof]

Are low-thrust engines still enabled? This mod is essentially required for using any kind of Ion engine in Realism Overhaul.

EDIT: yes they are. There is a bug where the orbit eccentricity vector can precess if you are burning at apoapse, but it doesn't affect angular momentum or energy so it isn't too bad. It doesn't affect common gameplay situations such as spiraling out from low orbit or doing interplanetary burns. I definitely liked using this with the near future pack on RO/RSS.

I'd pretty much like to see this useful mod fixed for latest versions of KSP.

[HagbardCeline]

+1

Need orbital decay.

[cipherpunks]

I'm still trying to live without it, using TimeControl HyperWarp functionality. As long as part count stays very low, it works. Sometimes problems with SAS PID (about which Squad doesn't seem to care) arise, but often I can burn Xenon at 11-13x.

Still the need of orbital decay, and higher still warp speeds (without thrust vector migrating from node vector preferably).

Upd: Whoa! Just found this. Might solve orbital decay indeed.
