github how high is geostationary orbit? google and wikipedia say 35,786 km and scott manley says 40k or 42k I forget. It seems that almost everywhere you go its a bit different. Is it just not important the exact height since once you get about that high you fine tune with orbital period instead? Did he just add the radius for the earth to the number so that he could utilize his delta-v equations?

What is the typical ram usage for a basic 32bit windows install. I am coming from x64 linux. Could I get away with 4k dds textures? Is it possible to install 8k versions of just the earth/moon. I am using rp-0 so i dont have anymore part mods than what is "required" for that.

Where can I get the sxt campatibility patch so I can use Rp-0 on .25?

What texture package are you using for rss on 32bit? Basic install with just no other part mods exept sxt/revamp and remotetech/procedural, basicly barebones. Im coming from linux x64. Where do I get the patch for .25 ven's stock revamp to allow sxt to work? it seems he updated it and the patch isnt in the thread anymore.

you could use an upside down procedural interstage to surround a cluster of separations or smaller srbs

Just a thought, with the career mode limitations on procedural srb/battery etc. what about limiting the total amount of fuel/ resource instead of the size? If the size is bigger than it empties some of the contents. That way you can shape it nearly anyway to fit the application without being roadblocked by size restrictions. Ive been trying to size things to match and the size limits have made me spend alot more time trying to biuld because I have to change everything each time I run into an issue with size or shape.

I do understand that actually, I was just about to add a comment about it but I answered my own question. The rl 10 engine i get access to in rp-0. Sxt/ or stock im not sure where it comes from has its attachment node a bit too low so that the tankbutt clips into the tank above it. The engines from fasa have very good tank-buttless models but the file structure is way different than other mods, I have to prune the parts out manually.

Whoa, mind blown. I totally get it now thanks a lot. I knew that it was more efficient but I never quite understood why/how until now.

make that 10 minute launch not 20. - - - Updated - - - Ive been digging at it for a few weeks (your not the first to say it) but I just dont get the whole triangle. I do know that you save fuel but I don't quite understand exactly how. I understand geometry and math fairly well too, so I thought it would come to me. I guess I just haven't put it together yet. Can you attempt to explain it please? - - - Updated - - - Has anyone had a problem with using a collumn of the cubic octagonal struts (usually 4) and attaching 4 goo canisters to it? I have found that you can fit that behind a 1.25m heatshield which is the biggest you get early in rp-0. Anyway upon re-entry the goo canisters slide through the bottom of the heatshield and burn up. this happens with the procedural structural part too (but not the procedural battery or a fuel tank) I have also noticed that after the shoot deploys it stretches the struts apart, creating gaps like they are attached with an invisible rope.

Its 2-3 degress initial pitch not 5. i launch manually with mechjeb smart a.s.s.. I don't have the time/patient to figure out a mechjeb profile with a 20 minute launch each attempt. Smart a.s.s. lets you precisely control maneuvers.

Got the sounding rocket guidance? Ive found it hazs a biult in small antenna.

Nathankell, or anyone else more knowledgeable on the subject than myself. Is their a specific reason why sounding rockets had super high twr booster stages that lasted a second or two instead of a longer burning boost stage? One thing I figured out from model rocketry is that an engine that burns twice as long at half the power can greatly increase the altitude. Also how do you survive launching a sounding rocket with an srb with anything other then a low twr? An example, your aerobee 950, even launching it straight up I burn up before I can even seperate and it is only a 4.4 twr. The only way I have gotten an all SRB first stage with any decent delta-v to work without burning up on me is to raise the burn time so that the twr is as low as what I use to launch humans. My usual first mission of a new career is an aerobee type rocket with a slow burning srb booster stage on the bottom of it and even then ascent can get pretty violent.

that was the point of boosting apogee at the dn, so I could be at the AN when I circuarised so I could change inclination too.

If I were to do that I would need a launcher with enough delta v to circularize 3 times. Thats about 1,000m/s each time right? plus the delta -v needed to de-circularize so you would need `9800 to orbit. another 3,000 to raise apogee to 35,786 and then the ~4000 you use for placing each satellite correct?

I was thinking about launching a geostationay constellation of 3 satellites arranged 120 degrees apart. I was pondering how to do this. I am thinking that the bet wy is to use a single launch to log all 3. Here is what I have come up with so far. I have not tried this because I am waiting on a few more nodes in career mode. so I am still fuzzy on whether this is the best way to do it. Step 1 do a routine easterly launch into a parking orbit ~ 200kms Step 2 Raise apoapsis to ~35,786 Kms (35,786,000Mm) Step 3 Somehow manipulate the orbital period to be 2/3 of a sidereal day (15 hrs 57 mins and 22.7 seconds, I believe) Im not sure exactly how I would do this without lowering the apoapsis in the process. Step 4 Decouple first satellite and circularize/burn to change inclination. Since I Boosted my Apoapsis at the DN I should be right at the AN when I get there. Step 5 Switch back to launcher and time warp one full orbit, since the non circularized orbit has an orbital period 1/3rd smaller it should complete exactly 1/3rd sooner and therefore put me in the perfect position to insert the next satelite. Step 6 de-couple/circularize/change plane just like Step 4. Step 7 Repeat the step 5/6 and this time when I de-couple I de-orbit the apogee booster that I used to raise apogee when I decouple so that I have three evenly spaced geostationary satellites. Step 8 Profit I figure that the individual satellites each need ~2000 m/s delta-v (covers circularization and inclination change aswell as handles "station-keeping"). The launcher itself would need need about 12000 m/s (parking orbit, apogee boost, and de-orbit). Is this the best method to go about achieving an evenly space geostationary constellation? Are my numbers right?

I must need to look again

8 of the communitron antena is enough for a geostationary satelite correct? you do not need a dts-m1? Ckan install is the main reason I have not upgraded to .90 yet and last I checked only .25 ckan even has RO available.

I looked and there is not a list of definate not supported ods like there used to be. woould be helpful if it was back.

Ckan for .25 does not install module manager anymore. also it installs the .90 version of tweakscale. THis makes it not possible to do a ckan install of .25 RO anymore and there is not a .9 version on ckan.

its not just the procedural srbs. the procedural thrust plate does the same. I believe it limits the size base on the tech progression. the problem I run into is that the things don't line up. Take the procedural battery for example. if you make the shape a smooth cone the bottom starts at 1m diameter yet its not possible to make it bigger or it shrinks to .6 and its not possible to make it .9 or it jumps straight to .5 and gets stuck there.

Ive only got those big ugly non stowable solar panels, when do you unlock the good ones?

do you know which mod adds a =n rs 25 engine (single and not clustered)?

read ferries guide and the posts I made on the last few pages.

mechjeb has a button that says "all stats" app still seems high. in half of the ascent you are already almost as high as you are at the end. you only need to get a periapsis above 200km or so to avoid decay and any higher of an app apsis than that is using more fuel at the expense of periapsis height.

Dont start your turn till ~100m/s . Read ferrams guide in the op. My apo at 45 degrees is 50 ish km. This is for a 200km circular parking orbit. Uses a lower stage with about 4500 m/s atmospheric delta-v (1.3 slt)and an upper stage with about 4500 m/s vac delta-v (.75 Twr)
