A specific frequency band used for satellite communication. It is part of the electromagnetic spectrum and is characterised by its unique set of properties, including signal propagation, bandwidth, and available spectrum.
Satellite communication systems utilise different frequency bands for transmitting and receiving signals. The S-band falls within the microwave frequency range, typically ranging from 2 to 4 gigahertz (GHz). It is widely used in various satellite applications, including telecommunications, remote sensing, weather monitoring, and scientific research.
The S-band offers several advantages for satellite communication. Its signals can penetrate through atmospheric conditions, such as rain and fog, more effectively compared to higher frequency bands. This makes it suitable for reliable and robust communication, particularly in challenging weather conditions or densely populated areas where signal interference may occur.
Spire’s proprietary ground station network of 30+ station and 70+ antennas across 16+ countries collect signals of interest across VHF, UHF, S, X, L Ka, and Ku band.
