x Band Satellite Communication operates in the part of the X band or Super High Frequency (SHF) spectrum which is designated by the International Telecommunication Union (ITU) for satellite communication, which is those frequencies in the range 7.25 GHz to 7.75 GHz (Space to Earth) and 7.9 GHz to 8.4 GHz (Earth to Space).

The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of the X band is rather indefinitely set at approximately 7.0–11.2 GHz. [citation needed] In radar engineering, the frequency range is specified by the ...
The radio frequencies used for spacecraft communication are in the microwave part of the radio spectrum; S band (2.29–2.30 GHz), X band (8.40–8.50 GHz) and Ka band (31.8–32.3 GHz). In addition to receiving radio signals from the spacecraft ( downlink signals), the antennas also transmit commands to the spacecraft ( uplink signals) with ...
Illustration of the WGS satellites in its two configurations, known as Block I (left) and Block II (right) The Wideband Global SATCOM system (WGS) is a high capacity United States Space Force satellite communications system planned for use in partnership by the United States Department of Defense (DoD), Canadian Department of National Defence (DND) and the Australian Department of Defence.

The satellites orbit in a circular low Earth orbit at about 500 km (310 mi) altitude [325] in a high-inclination orbit for a planned six to twelve-month duration. The satellites communicate with three testing ground stations in Washington State and California for short-term experiments of less than ten minutes duration, roughly daily. [320] [326]
Spaceflight. A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and ...
