Satellite Internet access is Internet access provided through communications satellites.
Modern satellite Internet service is typically provided to users through geostationary satellites that can offer high data speeds, with newer satellites achieving downstream data speeds up to 15 Mbps.
Satellite Internet generally relies on three primary components:
- a satellite in geostationary orbit (sometimes referred to as a geosynchronous Earth orbit, or GEO),
- a number of ground stations known as gateways that relay Internet data to and from the satellite via radio waves (microwave), and
- a VSAT (very-small-aperture terminal) dish antenna with a transceiver, located at the subscriber’s premises.
