Mechjeb has a config file with the co-ordinates, heights and approach directions of Airfields that have been manually added to it. If you want it to land at your airfields you will have to go to them with a mechjeb unit close to the ground. Use the custom mechjeb window to copy to clipboard the co-ordinates and height at 1 end of the runway , pop out to desktop and paste in txt document, pop back in and do the same at the other end. Make sure you add a note near your data in the text file to say which runway they are for. Repeat this process for all your runways. and then go into the config and use the set up for runways you see there as a template to create your bespoke locations.

It is called LandingSites.cfg

Here is an example I did ages ago for Kerbinside and Hafco. The first 4 are rocket landing sites, you want everything after where it says Runways.

Thank you for this.  I will give it a try.

It seems that MechJeb does not treat Ion Thrusters as "Engines". We can not properly use Ion Thrusters as our only source of propulsion with MechJeb when doing maneuvers in space. MechJeb does this weird sputter-sputter-thrust-thrust thing at about 50% engines with Ion Thrusters and it's not actually usable. Also MechJeb AutoLand will never calculate landing properly if we're using Ion Thrusters as our only source of propulsion. Can this please be fixed? Ion Thrusters as primary propulsion are a very important part of "Super Deep Space" missions.

Came back to KSP after some pause and installed 1.12.2 and Mechjeb 2 (absolute great mod, loving it!) and some other mods.

When using Auto-Rendevouz, aligning planes and first node (interception) works as I am used to, but then it gets a bit strange. Mechjeb does create the next node (match speed at closest approach), but instead of warping directly to it Mechjeb does only a short time-warp and then does a very small correction burn, then again a small timewarp and again a very small correction burn => rinse & repeat. This repeats for some time until the final node is reached and executed. The small burns are not shown as nodes.

Is this an intended new behaviour, did I miss on a setting or could it be a problem with my install? Any ideas/help appreciated!

 

I'm curious how close you were to the target when you initiated this because if fairly close, an approach target->coast->kill relative velocity->repeat is what most people do manually when a lowest dv hohmann transfer would be days or weeks away because the target is so nearby.  I really don't know but am curious.  I typically use kOS for most everything but rover piloting, tedious docking sitations (when I have the RCS dv to spare for MJ to gobble), and when I get lazy in which case MJ gets called up.  Also I should add to the previous stipulation that the target is close *and* the target orbit is close to the ship orbit, especially with regards to SMA

Mechjeb has a config file with the co-ordinates, heights and approach directions of Airfields that have been manually added to it. If you want it to land at your airfields you will have to go to them with a mechjeb unit close to the ground. Use the custom mechjeb window to copy to clipboard the co-ordinates and height at 1 end of the runway , pop out to desktop and paste in txt document, pop back in and do the same at the other end. Make sure you add a note near your data in the text file to say which runway they are for. Repeat this process for all your runways. and then go into the config and use the set up for runways you see there as a template to create your bespoke locations.

It is called LandingSites.cfg

Here is an example I did ages ago for Kerbinside and Hafco. The first 4 are rocket landing sites, you want everything after where it says Runways.

Alright.  So I did edit the cfg file and it looks right, but, in game, it doesn't appear to be reading the file.  Still trying to take me to the default coords.  I'm setting body = "Earth".  Is that correct?  Also, I only changed the values for the KSC runways and left everything else unchanged.  Do all body values need to be set to Earth even though I am not using them?

Only the places you are trying to land count as far as I am aware. I don't think you need to change them all, and it has been a while since I did this myself. I have never played RSS myself. I would make a copy of the LandingSites config, rename the original to LandingSites.txt, Strip out everything you don't need from the copy, make sure all your brackets and lines are set out are right. Try it with "Earth" and if it doesn't work then try it with Earth , no inverted commas. I only know the Earth part because it is in the original config. Be very sure you haven't made a syntax error anywhere. It only takes a small 1 to stop things working. Oh, also just remembered, the very first 2 KSC runway both directions and island both direction, are hard coded, even if you remove them in the config they will still be on the landing list at the original co-ordinates. @Maker16

Ahhh...That last bit is probably the issue then.  The original KSC landing site is what I was editing.  I'll try creating alternate entries to see what that does.  Thanks again for the assist.

I'm curious how close you were to the target when you initiated this because if fairly close, an approach target->coast->kill relative velocity->repeat is what most people do manually when a lowest dv hohmann transfer would be days or weeks away because the target is so nearby.  I really don't know but am curious.  I typically use kOS for most everything but rover piloting, tedious docking sitations (when I have the RCS dv to spare for MJ to gobble), and when I get lazy in which case MJ gets called up.  Also I should add to the previous stipulation that the target is close *and* the target orbit is close to the ship orbit, especially with regards to SMA

Target was as space station 150 x 350 km, Incl. 50° and craft was launched into 80 x 80 km, Incl. approx. 49°. Rendevouz-Autopilot matched planes and created & executed node for interception after 0.8 orbits. Everything worked as I expected until here, but then it started to get weird, as MJ created the node to align velocity on closest approach. The node was created, MJ aligned to the node marker and started to TimeWarp, but directly dropped out of the warp and did some minor burn, the TimeWarp started again and directly stopped and another minor burn happened. This repeated over and over again until the actual node to align velocity was reached and executed.

It reminded me of MJ dropping out of TimeWarp when the warp takes a long time and the alignment starts to drift to far from the node marker. In that case I am used to MJ dropping out of TimeWarp, re-aligning the craft and starting the warp again. But usually this only happens 1x, if at all. I my case it happened like every 4 seconds and I did actually not see the alignment to the node marker being off at all.

Anyway, did a clean install and can't reproduce it for the moment. So fingers crossed it is gone. Using some mods not yet released for 1.12, but they are mostly parts (like Near Future Construction from Nertea), so I wouldn't think they caused this.

That sounds a lot like I've encountered when I had the wrong part selected as the control point.  The main engines are not in line with the fore vector of the control part.  Could that have been it?

I am having trouble getting an install in Ubuntu20.4. With the pre-compiled I get only the AR202 case, and the only module that works from it is the right-click option to rename vessel etc.

When I try to compile from git I get a single error about access to an object.

- Is it supposed to work with the very latest KSP(1.12.2.3xxx, mine gets updated all the time from Steam)

-Does the career option block any modules?

Thanks!

Hello.
I would like to propose to add a TWR limitation clause to Ascent Guidance.
Is it possible to do this?
Thanks.

It's already in there. Enable the box next to 'Limit acceleration to' and in the text entry box next to that, enter a value of 17.676

the gravity on kerbin is 9.81 m/s²

Thank you very much!
Only, excuse me, I would prefer to set the TWR limitation, and not the acceleration limitation.
Moreover, these two parameters are completely non-intuitive in relation to each other.
Sorry if that. But I'm just learning))) And "thrust-to-weight ratio" and "acceleration" are completely different concepts for me ...
Sorry if that is.
Thanks.

Example:
My first stage has TWR == 2.3
MechJeb immediately uses full thrust, but I need TWR to be no more than 1.8

They have showed you how to stop MechJeb from using full thrust. Otherwise, yes they are different things.

Sorry, just add to that. Your TWR is based on the physical properties of your craft, mass vs the maximum thrust. MJ can't change your mass but it can limit how much thrust it uses. You could do this yourself by manually adjusting the thrust limiter on your engines.

So the fact of the matter is that "manually" I can support the TWR I need, but then I no longer use MJ!
I propose to add a limitation of exactly TWR, so that from the moment of start and until the end of the ascent, MJ itself maintains the given TWR.

Just my personal opinion, but I think MJ's ascent guidance is, if anything, already a bit too overburdened by options to add one like this. There are other ascent/descent options I'd put a lot higher on my personal list, though I recognize that my personal preferences don't translate to the author's. (For example, the lack of autostaging on descent causes a fair number of crashes for me; other people have pointed out tricks that help, but not enough to keep me from quicksaving before every landing). The only difference of substance between limiting TWR and thrust is that the TWR increases as fuel burns off. I don't consider a simple factor of diving by mass and local gravity to be "of substance". Note that there are already displays of TWR in various places if one finds it too much trouble to divide.

They really aren't (different in concept), unless you launch from a different planetary body with a different gravitational constant. So then you have to use a different value when setting up your launch profile.

^^^^^^ THIS ^^^^^^^^^^^^

The UI is already too crowded and there's been way too much feature creep over the past few years.

There's already a way to limit by TWR that just requires some simple math and does the same thing

If having a TWR limiter is your only reason for using MJ then you should do without MJ.

And I apologize for being overly blunt but the statement stands.

Well, of course not)))
This is far from the only thing I need from MJ.
As I said, I'm just getting started. Therefore, MJ is a teacher for me! I have seen career guides in which a person creates absolutely all maneuvers by hand.
I can not do that. Although I understand it. Without MJ, you can see the change in TWR, but you cannot see the acceleration. That is why I would like to be able to limit exactly TWR. For MJ, it is easy to take into account all the nuances on each planet, but for me personally ... :(

With regard to "congestion". I disagree with this statement.
MJ is, in fact, a control computer. If it only contains the command to "take off" and "land", then it will no longer be a computer.
For me personally, all dashboards are unnecessary. Not needed yet. Therefore, I made my own panel for myself with the parameters I personally needed. And this is really cool!

Landing autopilot, on the Moon in particular, works well if you do not enable automatic time acceleration. Otherwise, he simply does not have time to turn off this acceleration in time.

Who said you had to stop using MechJeb if you manually adjust the thrust limiters when building your craft? It is "Thrust To Weight Ratio" If you limit your thrust then you lower your TWR and then you don't need to adjust MechJeb. When you build there is a button along the bottom that allows you to choose what info to show. It is the Delta V button. If you have TWR ticked then right click on the orange part of the staging list and it will slide open to show your current figures. Adjust your limiters and the TWR will change accordingly, so you can work out how much to change it.
