Question about orbits

[shoogar]

My first post here, hello!

I have a small problem with Orbiter. I'm trying to synch orbits with ISS and I have a slightly elliptical orbit. The problem is my aphelion steadily and slowly increases. I've verified I'm not putting input into my orbit.

Any ideas? Suggestions?

Can be normal, as long as it slowly increases. Sun and moon also accelerate you and change your orbit. A satellite reached 50000 km apogee once that way.

Firstly, make sure you hit the star key on your numpad to shut down your engines completely. A tiny residual prograde thrust may result in what you describe.
