Keostational contract

[SpacedCowboy]

I can usually ace just about any probe/sat/orbit contract mission control can throw at me but this one has got me stuck. The contract calls for a perfectly circularized equatorial orbit. It has a target icon to click on

I meet all the orbital requirements.( and yes I'm going the right way ) but can't seem to complete the contract. Have to hold over the keostational  icon for ( of course ) ten seconds, but I can't get there.

What's the trick?

is this one of the ones that you must have a line of site of your target?

By "can't get there" I assume the problem is to find the right timing to do the transfer?

If that's the case, then just treat it as a Mun transfer - start from LKO, imagine a hypothetical object on the keostationary orbit right above your target. When the virtual "target" is about to appear at horizon, burn. If there's any error, you can always correct at keostationary orbit, wait for one period, and next time it should be all good. Crude method, but often good enough and doesn't need math/calculator to execute. (although to understand why the same method can roughly apply here you can do a little bit of math here, it's not hard - just some Kepler's third law plus some crude approximations).

Not crude at all! Gonna try that. Thanx for the input.

Yes, and then hold for ten seconds.

what i always do is first get into a regilar keyostat orbit,  then lower or raise one side depending on if im ahead or behind. then warp to the keostat altitude over n over until they line up and quickly circulize again lol crude but does the trick.

[SpacedCowboy]

Alright, I'll try that also.

You have to end up a little bit ahead of the waypoint on the ground to complete the contract. If you are close but not quite in the right spot, you can always slightly raise or lower your ap or pe until it says you are lined up, then circularize it again.
