  1. Awesome. Let me know if there's any compatibility issues with planet rescaling - like I say, it should work, but you never know...
  2. Those suicide burn calculators only work if you're descending directly towards the body. Mine works for any suborbital trajectory, which is (though I do say so myself) a much more difficult problem. On top of the standard dynamics of the problem (e.g. changing fuel mass), you have to 2 dimensions to deal with instead of one AND (most importantly) the changing terrain height over the course of the descent.
  3. It should do. Benefits should roughly scale with overall dV required to land. It's all relative, anyway - it really depends on how good your manual landings are. When I've tested it I've typically saved anything from 100-200m/s on the Mun (where the descent itself is a few hundred m/s) to upwards of 500m/s on some Tylo descents. Basically, this mod allows you to time your retrograde thrust perfectly so that you come to a stop just above the surface. If you manage to luck out and time it perfectly on a manual descent you'll get exactly the same delta V result. If not, you'll either cras
  4. Alright, sorry about the delay. New version available at the link in the OP. Changes include: Added required dV to the post-calculation window Added predicted landing coords to post-calculation window. I will continue to look into marking the landing spot in map view Added option to change all gimbals to a given percentage in settings menu (a bit clunky but hopefully self-explanatory) Minor bug fixes Haven't tested these additions extensively so let me know how you go.
  5. Thanks for the recommendations! I'll have a release with (1) implemented for you shortly. Don't know why I didn't do this already. I agree (2) would be handy, not so much for RCS (is there any reason you can't just use the action group?) but gimbals can definitely be annoying. (3) would also be very nice, I can get the coordinates pretty easily but I'll have to look into marking the landing spot in map view or something.
  6. Hi there! Have you ever injected from solar orbit into a highly horizontal suborbital trajectory towards a huge lumpy rock, and wondered... ...What is the most delta-V efficient way to bring my vessel to a safe landing? Well, wonder no more! Download Source As you may be aware, the delta-V-optimal way to come to a stop over a non-atmospheric body is using 100% retrograde thrust (relative to surface). However, begin thrusting too early and you will come to a stop with a long way yet to fall - on the other hand, begin thrusting too late and you will find that t
  7. I'm working on yet another landing guidance plugin. I'm almost ready to share an early version, but I'm having trouble with the coordinate system. In particular, I'm trying to find the latitude and longitude of the active vessel on its current orbit at some arbitrary time in the future, taking into account the rotation of the planet. The code looks something like this (with a nod to KER for inspiration): Vector3d position = vessel.GetOrbit().getPositionAtUT(currentTime + deltaT); double bodyRot = 360 * (deltaT) / body.rotationPeriod; double lat = body.GetLatitude(position); double l
  8. @TheCardinal, good thought RE performance concerns. Your thoughts on (2) are noted, that'll probably be an easier place to start anyways.
  9. Hi all, Long time player/reader, first time poster. I'm keen to get into modding and I've got a couple of ideas that I think would be neat. I'm seeking the following feedback: (a) Do other people think the ideas would be cool and/or useful? ( Can any experienced modders point me in the right direction to get me started? I've read (and am fairly comfortable with) lots of the general modding material, but I'm still not really sure to start with the first idea. © Have these mods already been created? The two concepts are as follows: (1) A mod that allows idle Kerbals to perform some scripted walk
