Among the satellite technologies, special attention is paid to the development of satellite communication technologies based on VSAT (Very Small Aperture Terminal). Small ground station VSAT, a terminal with a very small antenna diameter (0.9 \u2026 3.5 m), allows the use of VSAT stations antennas. This makes it possible to significantly reduce the size and cost of ground stations, the power of their transmitters and make their use widespread. VSAT equipment makes it possible to build multiservice networks that provide all modern communication services: Internet access; telephone connection; transmission of audio and video information; reservation of existing communication channels; data collection, monitoring and remote control of industrial facilities, etc. Satellite signals, especially high-frequency bands Ku and Ka, are subject to attenuation during rain, fog, clouds. But this shortcoming is easily overcome when properly designing the network, choosing the technology and location of antennas.
\nThe scientific article is devoted to the study of the influence of the speed of digital information transmission in satellite networks based on VSAT – a small satellite ground station, at the appropriate signal-to-noise ratio at the input of the receiver of the subscriber satellite station on the probability of bit error. The technical characteristics of subscriber satellite stations operating in the Ku-frequency band 11\/14 GHz with an artificial satellite of the Earth in geostationary orbit are given. The dynamic range of signal power change at the input of the VSAT-based satellite ground receiver at different data rates is determined, which provides a given signal-to-noise ratio and bit error probability in the range of 10-7<\/sup> – 10-4<\/sup> for the required communication quality.
\nKeywords:<\/strong> VSAT-based terrestrial satellite station, digital data rate, signal strength at the receiver input, signal-to-noise ratio, bit error probability.<\/p>\n
