Question 3Using your answer to the previous question, explain why geostationary satellites are less useful for video calls.

Without the context of the previous question, it's difficult to provide a specific answer. However, generally speaking, geostationary satellites might be less useful for video calls due to the high latency.

Here's a step-by-step explanation:

1. Geostationary satellites orbit at a very high altitude (about 36,000 kilometers above the Earth). This means that any signal sent to or from the satellite has to travel this distance twice - once up to the satellite and once back down to the ground.

2. This long distance results in a delay, or latency, in the signal. This latency can be as much as 240 milliseconds for a round trip to the satellite and back.

3. In a video call, this latency can result in a noticeable delay in the conversation. This can make the conversation feel less natural and more difficult, as participants have to wait for the delayed responses.

4. Additionally, geostationary satellites have a fixed position relative to the Earth's surface. This means they can't provide coverage to the polar regions, which could be a problem for video calls between certain locations.

5. Lastly, signals from geostationary satellites can be affected by weather conditions, which can degrade the quality of a video call.

For these reasons, other technologies like fiber optic cables or low Earth orbit (LEO) satellites, which have lower latency, are often preferred for video calls.
