Geostationary Orbit

[DoyleChris]

I would like to know the best way to get a ship into a geostationary orbit near the Cape. I know that it hast to be on the equator and at 32,000 KM but what im trying to figure out is when to do my burns i want the high point to be at 80.67 Longitude because that is straight south of the Cape on the equator. but not sure when to do my burns on the other side of the earth.

GEO is 36MM, not 32MM. Also, the cape isn't at 80deg longitude, it's at 280.
The easiest way to do it is just to look at map MFD. Each of the little squares is 30deg of longitude. So find the cape and then just count 6 squares. This point is exactly opposite the cape, and shows where your burn should be centered.

To do the burn itself you need to calculate the burntime, and then burn 3/5 (of the time) prior to passing the point you found and 2/5 afterwards. Now you should be headed more or less to the right place, and can do your circularisation burn when you get there.

Well getting to the geostationary altitude is easy, as for the deg of longitude when i bring it up in the map mfd and select it it says its 80 degs West i think. Well the problem is the timing i can get the burn to work and put me near the longitude but i cant get close to the cape. what i need is a timer that gives me time to a specific longitude on the earth at my orbit, is there one out there i have tried auto burn but it only does it on the perigee and apogee.

Only very few satellites reach their GSO position directly. It is pretty common, that after launch, a long phase of coasting takes place, where the satellite slowly drifts to its target position.

This coasting works by having apogee/perigee a few km above/below the GSO, so that the orbit has a tiny difference to the 24 hours orbit period.
