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 .
The military use of the frequency spectrum is based on the provisions of the ITU Radio Regulations and the ITU Constitution (Article 48 and RR N.342).; A supplement to the NJFA for states of emergency, and times of crisis and war, on the use of radio spectrum for military purposes required by NATO forces or in support of NATO, caters for additional spectrum.
Radar-frequency bands according to IEEE standard [17] Band designation Frequency range Explanation of meaning of letters; HF: 0.003 to 0.03 GHz: High frequency [18] VHF: 0.03 to 0.3 GHz: Very high frequency [18] UHF: 0.3 to 1 GHz: Ultra-high frequency [18] L: 1 to 2 GHz: Long wave S: 2 to 4 GHz: Short wave C: 4 to 8 GHz: Compromise between S ...
It operated in the military SHF SATCOM frequency band of 7.25 to 8.4 GHz via a geosynchronous satellite, with a data rate of up to 512 kbit/s. The normal manning level for an VSC 501 station was a crew of two and the system could be set up to provide communications within 15 minutes. [8]
The spacecraft is equipped with two solar panels for generate power to its communications payload, which consists of cross-band military X-band, Ka-band transponders, + 10meters solar panels.Propulsion will be provided by an R-4D-15 apogee motor, with four XIPS-25 ion engines for station keeping.
Also, the equipment of military forces’ systems work in different bands and with several frequencies at the same time. As long as the electromagnetic spectrum is evaluated as an element of the asset list and the operational electronic architecture that today’s and future forces should have, the military forces make all the efforts to get ...
