Fixed-Satellite Service (FSS) supports fixed installations and serves as the backbone for various communication and broadcasting applications. FSS relies on geostationary satellites positioned at approximately 36,000 kilometers above the equator. Fixed Satellite Service (FSS) represents a major category of satellite communication services that establish stable and continuous communication links between stationary ground or sea-based stations. It serves a multitude of applications, encompassing television and radio broadcasting, internet connectivity, data communications, telephony, and various other services that demand unwavering and dependable communication channels. At the orbital height, the satellite's rotation period aligns precisely with that of the Earth, creating the illusion of immobility from a fixed point on the planet's surface. This unique attribute allows FSS to furnish persistent, steady communication links without necessitating the tracking of antennas. The latency factor can affect real-time applications like voice communication and online gaming, where minimizing delays is critical. FSS operates across various frequency bands, including C-band, Ku-band, and Ka-band.

Key Characteristics of Fixed Satellite Services -  

  • High Throughput: FSS satellites are equipped with high-capacity transponders, allowing them to handle large volumes of data traffic. This makes them ideal for services like direct-to-home (DTH) television broadcasting, internet access, and point-to-point data transmission.
  • Stable Coverage: Geostationary satellites remain fixed relative to the Earth's surface, providing stable and continuous coverage of a specific geographic area. This stability is essential for applications like broadcasting, where uninterrupted service is crucial.
  • Broadcast Services: One of the prominent applications of FSS is television broadcasting, including DTH and cable distribution. FSS enables the delivery of a vast number of channels to homes and businesses, offering a diverse range of content.
  • VSAT Networks: FSS also powers Very Small Aperture Terminal (VSAT) networks, which are widely used for enterprise connectivity, ATMs, remote sensing, and even connecting rural communities to the internet.
