8.2.2 Geostationary Satellites

• Geostationary satellites are designed to orbit Earth with a period of approximately 24 hours
• What is the orbital period of a geostationary satellite?

  ~24 hours
• Match the orbital characteristic with its value:

  Orbital Period ↔️ Approximately 24 hours

  Orbital Height ↔️ About 36,000 kilometers

  Orbital Direction ↔️ Eastward

  Coverage Area ↔️ Approximately 42%
• Geostationary satellites have an orbital period that matches Earth's rotation
• The required altitude for a geostationary orbit is approximately 36,000 km.


  True
• Why is the high altitude of 36,000 km necessary for a geostationary orbit?

  To match Earth's rotation
• What percentage of Earth's surface does a geostationary satellite typically cover?

  ~42%
• Why is an orbital speed of 11,000 km/h necessary for a geostationary orbit?

  To maintain a fixed position
• Geostationary satellites provide stable and consistent communication for telecommunications services.


  True
• Geostationary satellites cannot cover the polar regions due to their orbital characteristics.
• Geostationary satellites remain stationary over a specific point on Earth's surface.


  True
• The orbital height of a geostationary satellite is approximately 36,000 km
• Geostationary satellites orbit eastward to align with Earth's rotation.


  True
• Arrange the steps in the process of achieving a geostationary orbit:

  1️⃣ Launch the satellite into a lower orbit

  2️⃣ Adjust the altitude to 36,000 km

  3️⃣ Match the orbital period to 24 hours

  4️⃣ Align the orbital direction eastward
• The orbital speed required for a geostationary orbit is approximately 11,000 km/h, which is also 3 km per second
• Geostationary satellites are stationary relative to a specific point on Earth.


  True
• Match the orbital characteristic with its description:

  Orbital Period ↔️ Matches Earth's rotation

  Orbital Altitude ↔️ Approximately 36,000 km

  Orbital Direction ↔️ Eastward

  Coverage Area ↔️ About 42% of Earth
• Geostationary satellites are used for television broadcasting to transmit television signals
• What are some limitations of geostationary satellites?

  Time delay, signal weakness
