  Relative Position ↔️ Appears fixed in sky
• The orbital period of a low-Earth orbit satellite is approximately 90-120 minutes
• What is the orbital period of a geostationary satellite?

  24 hours
• Geostationary satellites must have a circular and equatorial orbit
• Geostationary satellites remain fixed over a particular location due to their 24-hour orbital period.


  True

• Geostationary satellites are used for communication, weather monitoring, and navigation systems.


  True
• How do geostationary satellites aid in weather monitoring?

  Track weather patterns
• What is the approximate altitude of geostationary satellites?

  35,786 km
• Geostationary satellites appear fixed in the sky relative to Earth.


  True
• To maintain a geostationary orbit, the satellite's altitude must be approximately 35,786 km above Earth's equator
• The orbital plane of a geostationary satellite must lie on the Earth's equator.

  True
• What are the crucial factors that allow a geostationary satellite to remain fixed over a location on Earth?

  Orbital period and altitude
• What is the typical altitude range for low-Earth orbit satellites?

  200-2,000 km
• Geostationary satellites remain fixed over a specific location because their orbital period is 24 hours.
• What are the primary uses of geostationary satellites?

  Communication, weather monitoring, navigation
• How do geostationary satellites contribute to weather monitoring?

  Real-time observation of weather systems
• Order the advantages and disadvantages of geostationary satellites based on their impact:

  1️⃣ Wide coverage area

  2️⃣ Continuous coverage

  3️⃣ Reliable communications

  4️⃣ High launch costs

  5️⃣ Latency issues

  6️⃣ Limited number of orbital slots
• The geostationary orbit has a limited number of available orbital slots, leading to potential congestion.


  True
• Match the advantage or disadvantage with its description:

  Wide coverage area ↔️ Covers a large portion of Earth from high altitude

  High launch costs ↔️ Requires significant energy to reach geostationary orbit

  Latency issues ↔️ Long signal transmission time due to high altitude

  Limited number of orbital slots ↔️ Potential congestion and interference
• What defines a geostationary satellite?

  Fixed relative to Earth
• The orbital period of a geostationary satellite is 24 hours to match Earth's rotation.


  True
• What is the altitude of a geostationary satellite compared to a low-Earth orbit satellite?

  Much higher
• Geostationary satellites provide continuous coverage because their orbital period matches Earth's rotation.

  True
• Match the property with the satellite type:

  Orbital Period of 24 hours ↔️ Geostationary Satellite

  Moves across the sky ↔️ Low-Earth Orbit Satellite
