# [1.7.x] Transfer Window Planner v1.7.1.0 (August 19)

No, because travelling from Low Kerbin Orbit to Mun or Minmus, or to just escape Kerbin's SOI, there aren't any  transfer windows.

There are, they just happen every 30 minutes or so. A trip to Minmus is just as much a Hohmann transfer within Kerbin's SOI as a trip to Duna is within solar SOI.

A "transfer window" normally refers to a situation where you have three bodies involved.  The math is imprecise and much more complex than what you are thinking of with a Hohmann transfer.

For a Hohmann transfer you simply need to find when you're at a point directly opposite where your target will be in half an orbit.  (If that gives a negative solution you missed it, look for the next such point.)

Things like Transfer Window Planner and the similar functionality in MechJeb, however, are looking at a more complex problem.

1)  Your target is in another SOI.  The simple math of a Hohmann calculation won't give the burn you need.

2)  As there are three bodies involved (the ship, the starting planet, the arrival planet) there almost certainly isn't a perfect solution.  At the point your planets are lined up perfectly it's almost certain your ship is not.  Thus, rather than a simple equation that spits out one answer you have a much more complex equation that must be tested over a whole range of values in order to find acceptable missions.

For a Hohmann burn the fuel use for a non-optimal burn goes up very rapidly as you get away from the optimum, you're going to want to do such burns as close to perfect as you can.  For an interplanetary burn the penalty goes up much slower, in general waiting around for your spacecraft to reach the correct point in it's orbit for the burn is going to have a very minor penalty.  (However, if you're orbiting near the edge of Eeloo's SOI and try to burn for Moho the error is so big you might as well forget about it--exit Eeloo's SOI on the inward side and then do it as a Hohmann maneuver.)  You can even send a fleet doing it one spacecraft per orbit without a big penalty.  (Just make sure their arrival times are also staggered as you can only fly one craft at once!)

Yes, I know, I wrote a mod to do all of this (the left image link in my signature). The point remains that a transfer window calculator can handle LKO->Minmus transfers if it so chooses (as mine in fact does).

• 1 month later...

A new version of this recompiled against 1.7.x with various fixes from myself and helpful community peeps is now available

• Recompile for 1.7.x
• Fixed display issues when transfer was impossible - result was NaN (Issue #53)
• Fixed up some Date Formatting (Thanks to @Aelfhe1m - Issue #51)
• Fixed up some altitude swapping (Thanks to nanathan - Issue #50)
• Fixed up some issues with the anglerendering (Thanks to codesquid - Issue #49)
• Fixed up some issues with drawing angles when not in the right scene
• Fixed issues with clamptoscreen for window
• Updated KACWrapper
• Added some ClickThrough locks for TS scene
• Fixed updated version check

Some issue found me after upgrading from 1.6.3.0 to  1.7

Issues:

• M key does not work to go into map mode.
• If  try an exit the game it just hangs such that I have to end ksp via task scheduler.
• Going back to 1.6.3.0 removes the issue.
• Updated via CKAN
• I miss not having this mod is the final issue.   I love it.

Also there was no "The plugin records troubleshooting data in the "<KSP_OS>\KSP_Data\output_log.txt"."    I think that my be rerelated to the fact my ksp has "C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\KSP_x64_Data" and may be the plug is trying to write to a location that does not exists.   Scan of all files under ksp did not find a "output_log.txt"  See I read your doc's ;-)

I'm also having those issues

In addition, planetary graphics were affected and the button for Trajectories would not spawn its window.
I'll try and post more data when I get time

Darn, thats no fun, and yes saw the bit about reading the docs

The log file moved a while ago, you can findit on windows in this path C:\Users\username\AppData\LocalLow\Squad\KerbalSpaceProgram\Player.log or very close to that. If your not on windows the other OS paths arelisted in this article: https://docs.unity3d.com/Manual/LogFiles.html

Usually can find the cause in that one, or KSP.log in the game folder f cant find that one

Hey Trigger, I am having some problems too. My full log is too big to post on pastebin or the forums, if you have somewhere I can put it let me know, but here's the errors I found:

Hi,

The latest update is crashing my game!!!!

What happens that at some point possible when switching scenes, the game starts generating an endless number of Null Reference Exceptions.

I traced to this mod (which was recently updated) and have two log files here, one which was without TWP and was fine, the second was with TWP and has all the errors:

I did this on stream on Sunday, Aug 25, here: https://www.twitch.tv/videos/472362870

The two logs were generated at approximately 2 hours, 16-18 minutes into the stream.

The test I was running was to get into a new game and to fly an airplane and crash it into a building (for entertainment purposes).

There is a NullRef there from ActionGroupManager, it's a harmless nullref which was ruled out by removing the mod and the problem continued to occur

Took me a while, but what I think you wanted to say was:

"Thanks all, I'll debug tonight after work"

Thanks for all the work!

I second this issue. At first I was pointing the finger to Kerbal Enginner and some possible change on module manager. But today the only mods that i installed were this one and few USI from roverdude. I spent most of my free time today running some tests. After I removed this mod the game started to work normally again.

Same issue here, and just narrowed it down to this. You guys beat me to it.

Maps not able to load, rotating right-drag around the active craft instead rotated the craft (and the distant planets, oddly, from the Distant Object Enhancement mod).  Also a waypoint flag in white centered on the craft.

Going back to 1.6.3 for now, thanks for hard work and efforts to improve.

Spent the last day of summer vacation figuring out what was breaking my game. That's not a complaint though, as I gained some good experience troubleshooting a log file and learning what a Null Reference Exception was

Same experience. I tried playing a new Galileo game, and thought the old mods were doing the crashing. Turns out it was TWP.

Same here.

It looks like this when it crashes:

Same problem.

Same (temporary) solution: Uninstall and wait for this *invaluable tool* to be updated.

For now, I'll go back to this: https://alexmoon.github.io/ksp/

Thanks in advance for the upcoming hotfix TriggerAu.

Also having the shower of NREs after switching scenes. The previous version of TWP worked fine though

I have TWP inside blizzy's toolbar, but this didn't appear this weekend until after I updated. Also playfield seems entirely broken, tried to rotate the camera around the ecliptic but didn't see Kerbin or the sun. Of course it was extremely laggy and jumpy with the camera controls so I'm not sure I actually swept a panorama. Hope that helps, I'll save the output if you need more info.

Hey @Raptus, I just reverted back to TWP v1.6.3.0 and it is working as normal! In case you already deleted that zip file, you can re-download it from Spacedock under the Changelog tab. Happy transfers!

Trying to be useful with my cry of same issue:

Looks like the icons are way point icons.

My mod list:

• Community Trait Icons
• CorrectCOL
• KER
• KerbNetController
• Docking Port Alignment Indicator
• PartAngleDisplay
• [x] Science!
• PreciseNode
• RCS buiild aid
• Trajectories
• KAC
• TransferWindowPlanner
• WaypointManager (given that the icons are waypoints this seems prime for conflicts)
• WindTunnel

Edit: looks like it doesn't play nice with way-points. The save lost almost all my custom way-points. I needed to revert saves after downgrading the mod.

Good lord, I spent two days trying to figure out what was borking my game. And of course as soon as I do: bam, a bunch of people saying the exact things I was googling on wednesday, to no avail. (thanks google)

I had been updating and modifying mods for compatibility (restock+TU recolor) and though I had fouled the works somehow.

Now, on a lighter note, here is the KSC flying through the galaxy: https://imgur.com/a/OK0cuBJ
