WebOrigin is the primary focus of the orbit. The fundamental plane is the orbital plane of the satellite. The principal direction (X-axis) points to periapsis. Y-axis is rotated 90o in the direction of orbital motion and lies in the orbital plane. Z-axis is along angular momentum vector (h) and completes the RH system. inches pronunciationWebThis apparent movement allows the satellite swath to cover a new area with each consecutive pass. The satellite's orbit and the rotation of the Earth work together to allow complete coverage of the Earth's surface, after it has completed one complete cycle of orbits.
