Auto rendezvous and auto docking

[DerekisV2]

hi is there a mod that can make my rocket fly to a orbit and then dock with a spacecraft
im a total noob
i tried mechjeb but i have no idea how to get it to fly it near my other spacecraft
watched all the tutorials they are all outdated
plus i have no idea what im doing
any help pls?

i know how to dock i dont know how to get to the spacecraft

MechJeb can do it. It's a multi-step process.

1) Get into orbit of the same body, usually Kerbin.
2) Target the craft you want to rendezvous with.
2a) Optional orbital adjustment, see below*
3) Hohmann Transfer to your target.
3a) Conditionally necessary; Fine-tune closest approach to target. Usually MechJeb gets you really close, but this works as a fallback plan.
4) Match velocities with target, at point of closest approach
5) Use the Rendezvous/Docking Autopilot. If you're just looking for a rendezvous, you may already be close enough at this point. Rescue missions don't require docking; you can have the rescuee EVA out and board your craft via a hatch. Hopefully you have an unobstructed hatch.

* -- If your orbit and the target's orbit are very similar in period, the time to the transfer window could be quite long. This is not likely to be a major issue in Low Kerbin Orbit, since all orbital periods are quite short, but it could be an issue at the Mun or similar. The way to fix this is to adjust your orbital period by pushing your apoapsis up. If you're using MechJeb, this should be a routine orbit adjustment. This is just how synodic periods[en.wikipedia.org] work, which also explains why the transfer windows to Eve and Duna are the most infrequent ones, while the transfers to Moho/Eeloo/Any OPM world are quite frequent.

yeah but when i enanble the hohman transfer it just doesent do anything it says next burn in 20minutes so i just time warped and it started to count 3 , 2 , 1 , 0 ,+1 , +2 ,+3

you need to manually get the maneuver sas active and manually throttle up at hte node, i assume

With Mechjeb :

1) as you said.

2) as you said.

3) Use Rendez-vous Autopilot (with +- 25 or 50 meters of final distance) : and then when activating the Rendez-vous to the targeted ship, Mechjeb will do all the stuff you described in your
3) to 5).

4) Use Docking Autopilot : first, select YOUR CURRENT SHIP "Clamp O Tron", then select the targeted ship's Clamp O Tron. Then, enable the Docking Autopilot & manually turn ON the RCS of your ship.

To OP : with those steps with Mechjeb, no problem for RDV & Docking.

You're better off learning how to do it yourself than relying on crutches like mechjeb. Believe me, I struggled with wrapping my brain around rendez-vous myself, just like you are, but once it clicks it's easy mode.

^This.

Mechjeb itself is really only good for automating routine tasks in my opinion. It isn't really suitable for doing anything complex.

MechJeb got lot of autopilots, info about rocket, etc. I using it and it's good for automated flying and landing. But better to don't use it lot of time, KSP will be boring then :)
