Easy (Relatively) Rendezvous and Docking

Space Flight [P]

I set this as a reply, but it may be better as a post. It took a single hint for it to "click" for me, and its a hint the Tutorial totally fails to mention. But this fella does

Assumptions:

  • you can set a target in map mode

  • you know how to use AN/DN to get your orbit on the same plane

  • you can then use prograde/retro to get an intercept <5km.

From there I was always lost.

Here’s the hint. The entire point once you set the intercept is to get the prograde marker and the target marker on top of each other and keep them there. (They will generally align as you approach each other)

Once you set the intercept transfer. move the Navball to target mode. And stay in map view so you can see the distance (Right click on your target like above)

Controls (RCS):

  • WASD - Handles where the ship is pointed. Use it to keep the Ship/orange thing on Target (pink bullseye)

  • H-N is forward backward/throttle to handle m/s speed on Target.

  • I-J-k-L will move the prograde (green) marker around and generally minimally affect your relative speed.

  • when close to your target [ and ] will allow you to quick switch between ships. You can use this to use the other ship to also target and align itself.

@ 15 km. use RCS and H-N to get speed to 50 m/s. (dont worry about prograde being right on, but if it is...keep it there or start moving it in that direction. But it can be a waste of RCS to normalize it at 50 m/s its much more controllable at slower speeds.)

  • Note in the case above i used WASD to keep the ship pointed at the Target. And I-J to move the prograde on top of Target. I had to use H a bit to keep forward momentum as well.

From here.... Just make sure your Speed is sane and controllable, Distance is going down and you keep prograde on Tgt from here out.

Basic relative speed rules: You can bend these speed rules as you get comfy).

This is amazing. Watched at least 4-5 different tutorial videos probably 3 times each, and I still couldn't quite understand all of the individual steps involved...but this summed it up perfectly.

Thank you!
