Fixed Satellite Service (FSS)
FSS is a type of satellite communication service which provides stable, continuous communication links between fixed ground-based or sea-based stations. These services are used for a variety of applications, including television and radio broadcasting, internet connectivity, data communications, telephony, and other services that require reliable and continuous communication channels.
FSS primarily relies on geostationary satellites, which orbit at an altitude of about 36,000 kilometers above the Earth’s equator. At this altitude, the satellites’ orbital period matches the Earth’s rotation, making them appear stationary from a fixed point on the ground. This allows FSS to provide continuous, stable communication links without the need for tracking antennas.
Due to the long distances between geostationary satellites and the Earth’s surface, FSS experiences a certain degree of latency in signal transmission. Round-trip latency for FSS typically ranges from 500 to 600 milliseconds. This can impact real-time applications, such as voice communication and online gaming, where low latency is crucial.
FSS operates on frequency bands including: C-band, Ku-band, and Ka-band. Each frequency band has its advantages and disadvantages in terms of signal strength, susceptibility to interference, and bandwidth. For example, C-band is less susceptible to rain fade but has lower bandwidth compared to Ku-band and Ka-band.
While FSS can provide coverage across wide geographic areas, it may have limitations in providing services at high latitudes, such as near the polar regions. This is due to the low elevation angle of the geostationary satellites, which can result in weaker signals and increased susceptibility to interference from terrestrial sources.
FSS requires ground-based equipment, including satellite dishes (antennas), transmitters, receivers, and modems, to enable communication with the satellites. The size and complexity of the equipment may vary depending on the specific application and the frequency band used.
The satellite communication industry is evolving rapidly, with developments in high-throughput satellites (HTS), very high-throughput satellites (VHTS), low Earth orbit (LEO) satellite constellations (e.g. Starlink and OneWeb), and advanced ground equipment (e.g. VSAT). These advancements have the potential to increase the capacity, coverage, and efficiency of FSS while reducing costs and improving the overall user experience.
