V Band Satellite Communication

This communication was between the u s.

V band satellite communication.

However for broadband communications provider advantech wireless the move to q v band is only marginally on the radar. Used for satellite communications. With relatively few satellites in orbit in this band there is a wider separation between adjacent satellites making it ideal for comms on the move cotm applications. Uplink 7 9 8 4 ghz.

The satellite business for operators especially is a long term one and so future requirements need to be addressed far in advance. Block diagram of a v band block up converter top and a q band. 60 ghz is attractive for secure satellite crosslinks because it allows for high data rates narrow beams and lying in a strong absorption band of oxygen provides protection. Such as the ka band 20 and 30 ghz.

15 1995 the v band at 60 ghz was used by the world s first crosslink communication between satellites in a constellation. Rf components in the q v band. Satellite operator interest in new bands must be expected as they must look so far ahead. The x band is used mainly for military communications and wideband global satcom wgs systems.

Downlink 7 25 7 75 ghz. Ka band 26 40 ghz communications satellites uplink in either the 27 5 ghz and 31 ghz bands and high resolution close range targeting radars on military aircraft. In the last 10 years satellite communication systems have evolved towards constellations with many satellites hundreds and thousands and small satellites orbiting in a large variety of orbits at different altitudes while still using the huge geostationary satellites in the clarke orbit. In europe ku band downlink is used from 10 7 ghz to 12 75 ghz for direct broadcast satellite services such as astra.
