Thank for answer but I think that if I can find a deorbit+entry+landing replay, I will, finally, learn how to bring the shuttle down. Someone can help me with a replay?

Hi. I know this was a 1001 times asked, but : Please give me some Help of AerobrakeMDF, I cannot precisely deorbit the shuttle. I end up somewhere but not near KSC anyway. Are roll reversals required to bleed of excess speed? Where I see on AerobrakeMDF the TIG(if its displayed) or the Dv...

And how I do that? :lol::cheers:

Can someone help me putting a payload on this addon : Delta IV Medium EELVs v2 ? I'm very very new to the simulator and I am still learning. :tiphat:

As far i know, no. But if you have that booklet with the launch parameters it is teoretically possible to make a guidance file. All I ask is how to do it...you know, practically :) Is there any tool for creating guidance files?

Yes, visualization. I was thinking to make a pre-programmed launch sequence and start it at the real-time liftoff. But to make that some work has to be done. Let's take for example the recent launch, GOES-P on a Delta IV. Here is the mission booklet ...

Hi, It is possible to use Orbiter as a real-time rocket launch tracker like the one from United Launch Alliance when they launch the Delta II and Delta IV ?

I've managed to use all 4 stages. With 1+2+3 i get into a 250x280 orbit. Now I must use the fourth stage to circularize it up to 350x350 using a Hohmann method. After the 3rd stage burnout & jettison I ignite the fourth stage. At this point, in the guidance file I have target(350). The problem...

You reffer to target(target_apogee) ? THis will not work because I get into orbit using 2 burns (1st stage+2nd stage then coasting period then 3rd stage burn).

Seems to work. Some minor tweaks (I want 3rd stage burn to last exactly to the point when orbit ecc is 0,00xx). Later I will post the final guidance txt so you can give me other advices, if I need.

Tell me the IRC server and channel name. EDIT: This is the original guidance program for polar orbit

I have read the instructions from the manual but I told you that I encounter problems before the third stage burn (up to this point all is nominal, even with the wrong parameters for the roll instruction). Can we speak on MSN/Skype/ICQ ?

You may be very right. Any idea? EDIT: Maybe in the scenario txt ?

I have read a bit. I told you that using roll instead pitch(with the same parameters) the rocket is pitching correctly (90->10 degrees). But just before the third stage ignition it starts to roll/pitch/yaw crazy :). If you can build me a guidance txt, I will remain thankful.

Thanks for all for replying to my thread. I tried the following but with no luck: The rocket remains at an angle of 80 (because of roll comand;thats why I used only roll for angle control) and at 50 km altitude its becoming uncontrollable. Can someone make for me a guidance txt using the data...

I'm trying to make an autopilot for the Vega rocket (plugin Vega launcher ) because the one that came with the plugin cannot achieve my desired orbit. I had also removed the rocket's fourth stage because is not needed for my desired orbit (300x300 LEO circular). I encounter problems with the...
