Editing the persistant.sfs

[douglabe]

[NOW FIXED ]

Hey guys!

I'm making a supermassive space station in orbit around Jool and half way through construction, I realised that it was orbiting the wrong way round LOL and it needs something like 8000 delta-V which I simply dont have :/

Is there a way of editing its save file in the persistant.sfs file in order to change the direction of its orbit around Jool? The reason why I want to do this is so I dont have to crash into each moon if I want to land on it.

Heres the codey bit in the persistant.sfs for the station, titled The Mothership:

I *think* if you change INC from 179.962907812783 to 0.000000000000 that might do it. I recall Scott Manley did a tutorial on editing the persistent file but I looked and couldn't find it.

this link explains how the file works pretty well..

i believe it says how to 180 your orbit.

Reversing an Orbit

To reverse an orbit, you must do three things:

1. Longitude of the Ascending Node must be placed on the other side of the central body.

LAN(new) = LAN(old) + 180 degrees.

2. Orbital Inclination must be rotated to point the orbit in the correct direction.

INC(new) = 180 degrees - INC(old)

3 Argument of Periapsis must be measured from the new LAN position.

LPE(new) = 180 degrees - LPE(old)

For circular, equatorial orbits, you can get away with just flipping the Inclination to 180 degrees.

Both replies helped me out a load so thanks so much, thats done it
