I have a contract to put a part on a satellite in a high Kerbin orbit (>GEO) and am looking for advice on how to rendezvous. Last time I did something like this, I couldn't get within less than 40km of the target, so I ended up just burning toward it, which worked because it was just a crew rescue contract and I could eva the kerbal over to the rescue ship, but this definitely won't work for this. I have docked a few times in low orbits, but is there any different techniques for higher ones?
Also: is there a way to increase the orbit line resolution?
