How does satellite communicate data to the ground station?

Satellites communicate data to ground stations using radio frequency (RF) signals. These signals are transmitted from the satellite's onboard antennas, which send data to the ground station's receiving antennas. The data is typically encoded and modulated to ensure efficient transmission and is then decoded and processed by ground station equipment for analysis and use. This communication can occur in various frequency bands, depending on the satellite's design and mission requirements.
