"geosynchronous" polar orbit

[BigFatStupidHead]

Hey folks,

   I want to set up a polar satellite that revolves at the same speed as Kerbin, so that it is always passing over the same parts of Kerbin. How do I set this up?

You calculate the orbital period (the amount of time it takes to make a complete orbit), and make it match a multiple of 6 hours. That way it'll sync up with the planet's rotation in some manner. If you want it 1:1, you put a satellite into a regular geosync orbit, but rotated 90 degrees.

Do these help?

Ok, so a 1:1 polar geosync orbit will still have an altitude of ~2886750m. Thanks!

I'd never heard of the Tundra orbit before, but I do use Molniya orbits. Good stuff.

It should. It should trace a circle over the map, I...think.

I think it will make a figure 8 from the perspective of a given point on Kerbin's surface if I'm not mistaken.  I think I'll give this a try once I finish riding out this damned hurricane that's headed right for us (I live in Jacksonville Fl).
