So, I'm having a small issue with Installation. I followed the directions to the letter, then downloaded the 1/10th Config (To shrink everything back down again) and I'm getting a NRE for RealFuels not being defined. However, I do not wish to use RealFuels so I was wondering if there was a way to get around that?

More information: I used the RSS.dll from BetterAtmospheres prior to installation, however I deleted the RealSolarSystem folder and performed the Install, then followed the instructions for installing the 1/10th config. I have not ever had RealFuels, nor was it needed for BetterAtmmospheres.

I didn't install RealFuels or BetterAtmmospheres and still works.

Nope, but that would be super easy to write. All you'd need would be CBName { ORBIT { inclination = 30 } } for each body...

It's a little more complicated since the inclination plane is measured from the ascending node. So you would also want to set the LAN(longitude of the ascending node) of each orbit to the same or similar values (0 for example).

Does anyone have a config file for the stock solar system? I'm currently working on downsizing the 10x stock system, but it would be much easier to work with the original. (Not to mention all the things I must have copied incorrectly from the Wiki...)

I asked yesterday on irc but you are AFK then so i come to ask in this thread instead.

I don't get what you mean in the OP:

New mask for city lights. Replace main.png in BoulderCo/CityLights/Textures. Note you need the latest Overhaul for them to work; will not work on EVE 7-3.

Do you mean that we must use EVE Overhaul with RSS if we want to use that city light mask? If i change to use EVE 7-3, is there any place i can get some other city light mask for RSS? (for some unknown reason, the EVE Overhaul cannot display cloud in map view so I guess I need to use EVE 7-3)

I'm currently trying to figure out how to launch into an ecliptic orbit from the KSC. Any help out there on finding out when those launch windows are? I'll work on it myself but if anyone knows off the top of their head that'd be real nice.

Does anyone know what the altitude for keostationary orbit is in 6.4x RSS?

The period of your orbit needs to be the same as the sidereal rotation period of the major body, aka, how long a day is on your planet. How are day lengths and planetary masses different in 6.4x RSS?

Anyways, your radius is: https://www.desmos.com/calculator/1iu233or0a

a is your semi-major axis. That's the average of your periapsis and apoapsis, plus the radius of the planet you're orbiting (if your apoapsis and periapsis are in altitude. Important to note is that in all these maths, you need to use distance to the center of the major body​, not altitude). So to get your geostationary orbital altitude, you'll need to subtract off the planet's radius. T is period in seconds, G is a constant I've entered, and M is the mass of the body you're orbiting. On the graph there I've entered a simple 24-hour day. IRL, it's slightly off from that, and Kerbal has a completely different day length. I'm not sure how 6.4x RSS does that, though, so you'll need to find out how many seconds are in the day and how massive that planet is.

Also keep in mind, you're not technically going for day length. What you need is sidereal rotation period. That's because over the course of a year, the sun, of course, moves through the sky, so we actually lose a day (or is it gain? Can't remember). So it's off by one day in a year. Very small difference, but important to note if you need high precision.

Thanks this helped alot! I calculated the altitude to be roughly about 26300k (needed a little bit of tweaking to get it exactly 24 hours and surface velocity 0 m/sec)

I tried to send my first probe to Venus, and i have problem.q2PElHf.gif

I used Trajectory Optimization Tool to calculate transfer window and i get this

dAGpcxB.gif

it looks like the planets are aligned like on the picture from TOT (Even position of the descending node is perfect), however shouldn't Venus be on that position on the day of arrival?

Personally I gave up on using TOT, couldn't get it to work well. Kerbal Alarm Clock and Protractor are sufficient for this kind of missions. (If using KAC, always use the "formula" option for setting launch window alarms)

Can anybody recommend a mod that has a balanced fuel tanks and engines for this. I am not read to go full RO yet and am looking for something where it is balanced for the full scale and not the stock scale. If not a mod than at least some guidance for the math to rescale the configs. My current mods are:

FAR

KAC

KJR

KW Rocketry

RealChutes

Blizzy's Toolbar

MechJeb

Docking Port Alignment Indicator

NavBall Enhancement

RSS

(Note the lack of DRE. I am not ready for that much realism yet as I rely very heavily on it to reduce my fuel requirements)

AIES aerospace, maybe? I don't know of any mods that can make it easier than realism, HyperEdit aside. Real Fuels, Procedural Tanks and AIES should give you plenty enough to make flying in the real solar system possible, though. And then there's Hyper Edit, but that's basically a cheat.

I'm personally finding it SUPER useful, though. I'm planning a mini Grand Tour and I need to make sure my lander will work at various locales so I zip it out with HyperEdit and test it out :P (once the landers are finished, THEN I can design the mothership...)

I know little about TOT (could never get it to work on mac) but yes, it seems as if Earth is in the correct departure position and Venus is in the correct arrival position, so your transfer is not going to work. Also your ascending/descending node are irrelevant to departure time, but relative inclination and normal/anti normal velocity in your departure burn. For reference, RSS starts on 1/1 1951 at 00:00, so you should be able to add your KSP Universal Time to that, and then use TOT to get an exact date rather than relying on angles.
