Flexible applications
The S-band (2-4GHz) frequency is used for satellite communication and radar. It is used by the shipping, aviation and space industries for its efficiency as a conduit for supplying vital real-time data and for high resilience to rain fade and other environmental interference.
S-band is used for an extensive range of cross-industry applications, including surface ship radar, weather radar, navigational assistance, vessel identification and tracking, air traffic control, inflight Wi-Fi and spacecraft telemetry. Large parabolic antenna systems are needed for the best communications performance, however, smaller, omni-directional S-band antenna systems are also available for specific applications.
Providers of S-band networks include Inmarsat, which launched its Inmarsat S EAN S-band satellite in June 2017 where Cobham SATCOM supplies the earth station infrastructure.
