Geosynchronous - An orbit around Earth whose orbital period is equal to a sidereal day (23 hours, 56 minutes), irrespective of its inclination. - A person on a point on Earth, will see a satellite in this orbit in the same place in the sky at the same time of the day, everyday.
Orbital inclination is the angle between the plane of an orbit and the equator. An orbital inclination of 0Â° is directly above the equator, 90Â° crosses right above the pole, and 180Â° orbits above the equator in the opposite direction of Earthâs spin.
