once I did my first rendezvous, the others were a piece of cake here's the skinny: 1. if your ship is ahead of your target ship, get a higher altitude than your target ship and circularize. Then warp so the target ship will catch up to you. 2. if your ship is behind your target ship, get a lower altitude than your target ship and circularize. Then warp so you will catch up with the target ship. use NML- and NML+ to adjust the tilt of your orbit to match the target ship. Use the RAD+ and RAD- to change the altitude of your orbit faster. once the two ships are within 100m of each other put the ships in either prograde or retrograde orientations, then right click your docking part and click "dock", do the same on the target ship. From there on use RCS to position yourself to the point where the two docking cones line up, they should start red, then turn green, then blue.
