표 1. | Table 1. 정지궤도와 비정지궤도 위성의 특징 비교 | Comparison of characteristics between geostationary and non-geostationary satellites.

Category	Geostationary satellite	Non-geostationary satellite
Definition	A satellite orbiting in a fixed orbit in the plane of the Earth’s equator	All satellites except for geostationary ones
Position	Uses a specific altitude of approximately 35,786 km above the equator	Altitudes vary and generally use lower orbits; orbital positions change continuously
Frequency sharing	Managed primarily through orbital separation	Managed primarily by distinguishing transmission times
Continuous operation	Can operate 24 hours from a fixed point relative to the Earth’s surface	Cannot operate 24 hours with a single satellite; requires a constellation of satellites for continuous coverage
Perspective of ground stations	Operates as a space station installed at a specific fixed point relative to the Earth’s surface	Operates as a space station installed at unspecified points
