Study Notes
Communications Satellites
- Main function: Relaying signals between ground stations
- Geostationary orbit: Altitude of 35,786 km
- Geostationary Satellites: Appear stationary in the sky from Earth's perspective
- Ground station antennas aim permanently at the spot of geostationary satellites: Because the satellite's position is fixed relative to a specific point on Earth
- Antennas on the ground in low Earth orbit satellite constellations have to follow the position of the satellites and switch between satellites frequently: Because the satellites are constantly moving in orbit
- Communications satellites use a wide range of radio and microwave frequencies: To avoid interference and allow for more efficient use of the spectrum
