Can a low altitude satellite be used for communication?

Yes, a low altitude satellite can be used for communication, though it typically requires a network of satellites to ensure continuous coverage due to their limited field of view. These satellites, often in Low Earth Orbit (LEO), can provide low-latency communication and are commonly used for applications like internet services and remote sensing. However, their lower altitude also means they must be more numerous compared to higher altitude satellites, like those in geostationary orbit, to maintain consistent connectivity.
