Hi, Hm, no way to set up constraints in the optimizer ahead of time? It'd be unfortunate if the optimizer found a solution for my lat/long/altitude specifications that ended up without line-of-sight to Kerbin. Also, I have the extra stations enable in KSP for the full DSN, not just the Tracking Station at KSC, so I'm really just interested in line-of-sight with Kerbin. Presumably I could add a few ground stations to fake it enough. I had thought so, but Solar Beta Angle is just the angle between the spacecraft's orbit and the sun. It doesn't tell you if your spacecraft is actually in sunlight or not. At least, as far as I understand it, which is not much. Oh, thanks, I always forget about the Animator. That might help to at least check if what I got from the optimizer is ok or not. Edit: Animator's showing it coming in on the dark side, naturally! Eyeballing things in the map view made me think as much. Ah well.

Also, btw, I managed to get KSP TOT running inside a docker container on my Mac - thanks again for the linux port!

Couple of quick questions that I think I saw answered somewhere in the last 135 pages, but I can't find it. I'm trying to use the Mission Planner to set up a Minmus rescue mission. I've added a ground station for the to-be-rescued kerbal, and I've got the optimizer set to end up in a low periapsis right over the correct lat/long, but I'd like to also: 1) Make sure we'll have comms with Kerbin when landed, as this is an unmanned rescue 2) Make sure we're arriving and landing during the daytime (e.g., sun at least higher than some angle above the horizon, ignoring local terrain) Thanks!

Is there a way to view the current inventory of items in the scrap yard? I'd like to clear out some early gen items, but would rather not have to click on things one by one in the VAB. Also, what do the "Whole-Vessel Quick Options" do? I don't understand what they're meant for. Thanks!

Looking forward to this!

This is really excellent. As the person who figured out how to get it running on a Mac kinda-sorta with WINE, at least for a few releases, I'm thrilled to see a full Linux port. Great work on that, and also the LVD looks amazing. Thanks so much for your continued efforts!

1) This is still happening with KSP 1.4.3. Is there any updates on getting this fixed? 2) If someone has access to change the KSPOGL.command linked in the OP, this would be a more portable solution that doesn't depend on KSP being installed in a specific location: DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" cd "${DIR}/KSP.app/Contents/MacOS" ./KSP -force-opengl

Howdy! On macOS 10.13, I still need to use the "-force-opengl" workaround to get it to actually launch. Is there any timeline on fixing this?

Ah, good, someone else reproduced that - I thought I was seeing this with pr5, but I haven't had time to go back and repro.

Neat!

Another feature request: It would be grand if the Rendezvous Maneuver Sequencer and the Optimal Two Burn Orbit Change tools automatically changed the central body ("Orbiting About") when pulling in the orbit from the KSP TOT plugin. I can't tell you how many times I've forgotten to change it and had ... interesting ... results. Also, the Orbit Change tool doesn't do anything when you right-click in the Final Orbit section and choose "Get Orbit from KSP".

Hiya @Arrowstar - still loving this amazing tool. Small feature request - remember the last remote host IP/hostname in the saved config. I'm having some issues trying to use finite maneuver. This is the first time I've given it a shot, so perhaps I've done something wrong? I had an impulsive Duna transfer maneuver set up, then converted it to finite and re-optimized. I then uploaded it to KSP, but the burn didn't end up with an encounter, much less anywhere near my target. A course-correction burn was requiring ~200 m/s delta-v. If I just used the original impulsive maneuver instead, I ended up with an encounter and only need a few m/s of correction. .mat files for finite and impulsive as well as a save file available here. I just now realized the save isn't from a vanilla install - the actual vessel in question (Duna Flyby Block 2) doesn't use any non-vanilla parts, though. Also, I think the MA in pre-release 5 isn't updating the visualizations after running the optimizer/changing initial state. Let me double-check, though.

Suggestion: delay the roll program until the rocket's above some minimal altitude (height of rocket's nose before launch?), to avoid wide rockets from banging into the launch clamps.

Yes, of course, this makes perfect sense. Derp. I read through that tutorial, but I must have missed that part. I'll go through it again. Thanks!

Ah, ok, good to know. I'd still like a good method to figure out what the best initial inclination is for a given planetary transfer window.

Another suggestion: I'd love to compute the best starting orbit (mostly inclination/RAAN/ArgP, I think) to start a given planetary transfer. I can start a whole mission with the assumption of an equatorial 100km orbit, but many transfers are of course better served with a better starting orbit. Naturally I'd then want an idea of when to actually launch in order to reach this orbit... I think you've done some work with this with the launch window planner.

I have a long burn coming up, so I thought I'd try the Maneuver Execution Assistant. It can read in the orbit from KSP ok, but it doesn't read the maneuver node. I can get all the data for the node inside of KSP except True Anomaly. So I thought I'd open up MCC Real Time System and get it there. However, the Orb Ops Console's Maneuvers Information pane only shows Burn UT and Time Until data, not True Anomaly. Two feature requests, please: In the execution assistant, add ability to right-click and read next maneuver node from KSP In the Orb Ops console, display the maneuver node's True Anomaly, to match what the execeution assistant wants Thanks!

Very nice tool, thanks.

Are you trying to follow the native Mac instructions? I haven't tried that in ages, since the build for macOS is extremely out of date. I was able to get a more recent build of KSP running using WINE. The 1.5.x releases were having problems at first, but I've just now tried with the latest WINE (1.9.21) and - hooray! - it seems to be working again. N.B.: You'll need to install the newer MCR_2015b_win64_installer.exe (linked on the first post). @Arrowstar Could you update the first post to point Mac users at these instructions? And update step 5 with the latest MCR filename, please. EDIT: Ok, not fully working - the images are all upside-down...

I have a question about how to use the guessing/improve launch functionality. When I have a launch that's going poorly (clearly inefficient or not going to make orbit or so forth), when/how should I end it so GravityTurn is able to correctly update its guesses? Revert at any time? Do I have to wait for the launch to "complete" either by reaching orbit or crashing?

Use a mod that calculates orbital decay, like That way your expended debris will eventually fall in.

Yesssss, so happy to see someone keeping this alive.

Running it in WINE stopped working for me with the move to the most recent MATLAB runtime. I filed https://bugs.winehq.org/show_bug.cgi?id=40781 about the URI bug, but no one has looked into it, and it's beyond my ken to figure out. I've since bit the bullet and set up a Windows 10 VM just to run KSP TOT....

New item to remember between launches: name/IP address of the KSP host.

I'm getting the same "Could not successfully parse URI string" error with vcrun2015 installed.
