What size are the typical keep-inside boxes of geostationary telco satellites?

East-west errors are the kind most likely to get you in trouble with your neighbors, and are controlled essentially by changing the nadir distance. That is, if you're not exactly where you're ...

Is it possible to determine the classical orbital elements for an Elliptic Repeating SSO?

This paper might help answer your question. They look at repeating ground tracks and sun synchronous orbits. The seem to limit their discussion mainly to circular orbits, because they say perigee is ...

Plot ellipse using elements from TLE

It seems to me that EllipseCurve alone is not enough to represent satellite orbits, because it only deals with ellipses in a plane. To get the right 3D behavior, you will need to move the center, and ...

Where do I find ECEF coordinates of a satellite?

Where do I find ECEF coordinates of a satellite? You don't "find it." That information is not published. You'll have to compute it rather than find it. What is published for many satellites ...

Determine Yaw, Pitch, Roll from two vectors

If the satellite is initially pointing at [0,0,1] and you want to point it at [x,y,z], there are infinitely many options. Here are the ones that involve only two rotations around the satellite's ...

Determine Yaw, Pitch, Roll from two vectors

I think I've found a solution and I beg your pardon if I ask questions and answer myself but maybe someone can run into the same problem. Given s as the vector which points from the satellite to the ...

How could a satellite follow Earth around the Sun while staying outside of Earth's orbit?

If you are looking for a way to slightly reduce the warming energy coming from the Sun, you don’t need to block it with a large construct. You only need to diffuse a small percentage of the Sun’s rays ...
