This craft is equipped with a vizzy program which will fly itself from the launchpad to almost any target craft in orbit around Droo.
To dock, a target ship must have a docking port with the default part name, and it needs to be aligned to the center of mass.
Do not touch any controls while the program is running for best results.
Time warp up to 500x should be safe while traveling between most maneuvers. Do not be in a timewarp higher than 500x when the maneuver timer expires, or you could miss your burn window. For the final intercept. Use a maximum of 25x timewarp in the last moments before the final timer expires.
Time warp is reset to normal speed 15 seconds from the end of a maneuver timer. Do not re-engage timewarp at this point. Physics based fast forward might be ok depending on your system.

Try out this craft to use for target practice.
Known issues:
Launching from a higher latitude than a retrograde orbit's inclination will cause the program to become non responsive. It should be fine when launching to retrograde orbits from the equator though.
Rendezvous accuracy drops as the target's eccentricity approaches 1. Its designed to deal with this error, but you might get strange behavior when intercepting highly eccentric orbits combined with a low relative velocity.
With regards to the alignment with CoM issue, it occurred to me that since CoM changes as fuel is burnt and when craft dock/undock that ports anywhere other than on the nose or tail would present problems. KOS in KSP has access to the normal to the face of the port, so it is easier there.
Still, it occurred to me that if the position of the port is not on the centerline, one could try docking along the axis perpendicular to the centerline of the target craft that runs through the dock port position. Are part positions in vizzy the center of the part? Point being that non-centerline ports are likely facing perpendicular from the centerline
Hi the craft is great it worked the first time but there's a problem with the intercept separation and needs a bit more RCS fuel and could you please make it a bit bigger with enough space for three astronauts

@GoldenShadowGS thx
@RelativitySpaceSr2 There is a new version, but your screenshot appears to be mobile version, you'll need to wait until the funk bug is fixed before you can upgrade to it. New Version
bug
@SovietOnion1234 If RCS ran out, that could be why. If you made the craft bigger, it might need more RCS fuel
@GoldenShadowGS also is my RCS supposed to run out?
@SovietOnion1234 I can't offer a fix without debugging it.
When I tried docking it to my station, it came close, I selected the docking port, and it did nothing. Know a fix?
@GoldenShadowGS Thx :)
@iSpace Sure
@GoldenShadowGS Hi. We're iSpace development team. We are finding new partners. We need a reliable auto docking program for our Gamma Station Program. Though we're developing a new docking program, we need few months to finish it. Could we use your vizzy docking program? It's pretty cool and useful!
I am working on a new version which has support for hyperbolic orbits. I should be able to plan trajectories between different planets.
@OM3GA_AEROSPACE The Burn vectors and maneuver nodes are universal, but the actual burns require tuning for specific TWR.
I'm gonna guess that this isn't universal?
Very much surprised.. it works superb fine ... So it might be difficult,/ unstable to other rockets ..
But here's the trick to use this to build space station for new players like me..
1) modify the top most stage to anything we desire
2)but use tinker to give zero mass to most .. and making sure to keep RCS at proper place depending on center of mass of upper stage
3)docking needs some tricks... Switching RCS on/off several times will make it to attach to docking port .. sometimes needs to orient ur original base craft..
Thanks a lot... Using this I am building my space station very easily
Was actually surprised to see that it docked in literally 2 seconds !!!
I see. The automatic docking system seems to be quite complicated.
Thank you for your answer.
@GoldenShadowGS
@1918 The program is subdivided into discreet steps. from launch, circularization, inclination correction... But for best results you need to launch into an orbit which already closely matches the target's inclination.
I apologize for asking such a brazen question, but I would appreciate it if you could answer it.
I would like to use your automatic docking system as a reference to install an automatic docking system on my rocket and Reusable launch vehicle. At present, these vehicles can be automatically injected into Droo orbit.
From there, we would like to use your automated system as a reference for rendezvous and docking with the target.
Therefore, I would appreciate it if you could tell me what part of your automated docking system covers the process from injection into the Droo orbit to docking.
@Arthur705 It probably just needs some tuning to match the capabilities of the craft used.
@GoldenShadowGS It was Working fine till the Same craft used .Then I tried using simple heavy craft (with Rcs) and tried to dock by launching it. But gets crash at Circulation, inclination :-(
W@Arthur705 How it is not working?Does the craft have RCS?
