Degree

In space and astronautical engineering, degree refers to the measurement of an angle or inclination of a spacecraft or satellite relative to a reference plane. This measurement is important for determining the orientation and trajectory of the spacecraft or satellite. The most commonly used reference plane is the plane of the Earth's equator, and the angle is measured in degrees from this plane. The degree of inclination can affect the orbit of the spacecraft or satellite, as well as its visibility from different parts of the Earth. For example, a satellite in a polar orbit has a degree of inclination of 90 degrees, meaning it passes over the Earth's poles, while a satellite in a geostationary orbit has a degree of inclination of 0 degrees, meaning it remains stationary over a fixed point on the equator.
