Precision reentry?

[MedwedianPresident]

So, the problem is that my space shuttle (from Tiberion's mod) always lands somewhere in the Desert instead of reaching KSC. Where should i de-orbit/how shallow should be the angle/how to calculate the best trajectory for reentry so that you land at KSC or another certain location?

IF you put your Periapsis about 30km above the edge of the continent to the east of KSC you should land about where you need to. I know Scott Manley has a video explaining it somewhere.

Do you mean the italy-like isthmus?

Personally I use a periapsis of around 24km right above KSC, and then maneuver as necessary to come down on the runway.

EDIT: I use FAR so this may not apply to you

Looks more like Korea to me. Anyway, someone here made a handy chart...but I can't remember the username

I'd say... practice. Make a quicksave in orbit and then try what happens when you enter the atmosphere at various places and angles.

It's not about "put your periapsis at this height" because the result depends on your speed and your reentry angle, among other physical characteristics of your ship.

I found that if you're at low orbit and decrease your periapsis to about 40 km, you can keep that height for about 1/4 of the globe by burning downwards while being slightly decelerated by atmosphere. And when you get to the right place (about the eastern shore of the KSP continent), just dip below 30 km to slow down significantly and land.

Nice! I will try different methods. And is there a plugin which calculates atmospheric drag for patched conics?
