Understanding Communications Earth Satellites
Communications Earth satellites are designed to facilitate communication across vast distances. To perform their functions effectively, they must adhere to specific orbital characteristics.
Key Characteristics of Communications Satellites:
- Orbital Direction:
Communications satellites typically orbit the Earth from west to east, not east to west. This is because they are often placed in geostationary orbits, which revolve in the same direction as the Earth's rotation.
- Geostationary Orbit:
A critical aspect of communications satellites is their position in the equatorial plane. They must be in the equatorial plane to maintain a geostationary orbit. This allows them to appear stationary relative to a point on the Earth's surface.
- Coverage Area:
While a satellite can cover a wide area of the Earth's surface, it cannot be vertically above any location unless it is in a geostationary orbit. In such a case, it can only remain above the equator.
Conclusion:
Thus, the correct answer is option 'B': "Can be in the equatorial plane only." This is essential for the satellite's functionality, allowing it to provide consistent communication signals to designated areas on Earth. Understanding these principles is vital for grasping how satellite technology operates in modern communications.
