Understanding Geostationary Orbits

Why do geostationary satellites need to orbit above the equator?

• To avoid interference with other satellites

• To increase the speed of orbit

• To appear stationary to an observer on Earth

• To reduce the cost of launching

What happens to a satellite in a polar orbit?

• It orbits faster than geostationary satellites

• It requires no additional forces to maintain orbit

• It moves north to south or south to north

• It remains stationary above the equator

Why is an equatorial orbit the only one where a satellite appears stationary?

• Because it avoids atmospheric interference

• Because it is the cheapest orbit to maintain

• Because it aligns with the Earth's rotation

• Because it is the closest orbit to the Earth

What is required for a non-equatorial orbit to appear stationary?

• A higher altitude

• A faster orbital speed

• Additional propulsion

• A larger satellite

Why is relying on gravity the most efficient way to maintain a geostationary orbit?

• It increases the satellite's lifespan

• It requires no additional energy

• It allows for faster communication

• It reduces the risk of collision
