SpaceX Dragon Docking Simulator Speedrun

[CorvusCorax]

This is too easy!

Let's play this in HARD mode: Turn the HUD off. -- Simulate Sensor failure and dock like a pro
Or turn collisions off, and look at the insides of the ISS (sadly no internal textures, but one can still pretend)

Or make a deorbit burn - without getting warped back after 500 meters.

Feel free to install this user script in Chrome Tampermonkey or Firefox  Greasemonkey, and pimp your ISS-SIM

(Note: No, docking to other nodes than harmony isn't implemented yet, that's a TODO. Feel free to do so, I need to sleep)

Hmm, there's a bit of a bug. A rotation input will change the rotation rate by 0.1 degrees/s whether you're in precise mode or not, so you can end up with incorrect rates if you rotate a bit in imprecise mode, then cancel it in precise mode.

My time was 27.5 seconds! Took a lot of attempts!

 

 

 

Good god that's flinchy in all the best ways

[CorvusCorax]

I added a new version of the ISS-SIM-Customizer:
https://gist.github.com/CorvusCorax/d6e6e98c946b8bfad56563b514df23a9

New features:

1. Realistic docking constraints based on NASA IDA specifications (allows up to 4 degrees more angular deviation, but requires more precision in position and velocity)

2. Select docking port to dock with. Available options:

• IDA-2 on PMA-2
• Harmony Zenith
• Harmony Nadir
• PMA-3 (just squeeze in from underneath and push against that radiator)
• Zvezda
• Poisk
• Pirs
• Rassvet

[CorvusCorax]

Now I dare you to speedrun to Zvezda (aft port) with realistic docking constraints (0.1 m/s 0.1m distance, 4 degrees deviation allowed)

And then do it without HUD

Not sure I can handle this.

I still have PTSD from playing 3-D asteroids.

 

Like it's so bad that even if you gave me a scifi spaceship for free but told me the controls are ONLY manual... I would likely turn it down.

Which is sad.

 

I mean that game is ridicuously manual. 

It's like they put all the RCS on max thrust so that ever push you overcompensate for and have to correct.

Still can't see where's "Lock target".

Also, IR or RL?

Docking on Zvezda - Aft port - NO HUD / docking guidance - User script: https://gist.github.com/CorvusCorax/d6e6e98c946b8bfad56563b514df23a9 v 0.000003

Realistic docking constraints:
Position deviation: offset max 10 cm
Angular deviation: max 4°
Velocity: max 0.1 m/s
Angular rate: max 0.2°/s
Time: 1:30

This was mostly to demo the extension. The time can certainly be improved

[CorvusCorax]

New version v 0.000004 of the Customization userscript adds time warp.

https://gist.github.com/CorvusCorax/d6e6e98c946b8bfad56563b514df23a9

In case you get bored during your speedrun.

Also, proper orbital mechanics, so you can  now change your orbit, re-enter, or try to re-sync to the ISS and display some orbital parameters on screen.

No manouver nodes though >:>>>

What at first seemed a respectable time of 2:30 now looks like a sleepy tortoise taking it easy.

Confirmed. I fixed that bug in v 0.000009 of my CustomScript mod: https://gist.github.com/CorvusCorax/d6e6e98c946b8bfad56563b514df23a9

Also, you can now chose to be placed in a 198 km circular orbit and need to phase and rendezvous with ISS manually before docking.

Anyone wanna speedrun this?   There is timewarp!

 

[CorvusCorax]

I added a new feature to the userscript mod in v 0.000013 -- propellant utilisation is now monitored and displayed. That adds a new dimension to the speedrun.

Try to do it with less propellant.

We need some sort of formula to weigh propellant use against speed. I would suggest measuring the time and then add 1 second for every m/s of deltaV used.

Would that be fair?

[CorvusCorax]

New version 0.000014 has a frame and time counter - velocity is now independent of fps - unlike original ISS-SIM which no longer gives fast systems an unfair advantage in speed runs.

Just came here to post that you had done this. Didn't realize you were here as well.

[kerbiloid]

Could, please, somebody explain me, where is that canyon? Can't find it. :(

Yes, a stopwatch is good. Unfortunately there is not an internal timer in the simulation.

There is an extension that adds an on screen timer (https://chrome.google.com/webstore/detail/iss-sim-speedrun-timer/necjicdkncboglcmpmhgeghdiplfjbik) I didn't make it I don't know if it has viruses
