The 30/20 GHz band is used in communications satellite uplinks in either the 27.5 GHz or 31 GHz bands, [5] and in high-resolution, close-range targeting radars aboard military airplanes. Some frequencies in this radio band are used for vehicle speed detection by law enforcement. [6]
With the need to speed up transmission of high-rate science data from space missions, Ka-band, at 26 GHz, is now considered the spectrum of the future for NASA communications. Compared with S-band, Ka-band has data transmission rates that are hundreds of times faster.
Network Initiative for Ka-band Advancement (NIKA) Objectives: evolve and modernize the NASA’s Near Space Network to provide increased capbility primarily for polar orbiting missions • Four new 11-m tri-band antennas (Virginia, Alaska, Norway, Chile) • Integrated high-speed cloud and data services
Compare Ku Vs Ka bands in satellite communication including advantages, disadvantages and difference between them.
Ka band transceivers, transmitters, and receivers are satellite communication sub-systems for receiving (uplinking) and transmitting (downlinking) data between the ground and space in the frequency range of 26 to 40 GHz. In this article we give a brief overview of how satellite Ka band communications systems work, followed by details of ...
Key Takeaways. Ka-band satellite communication has increased bandwidth, which is double that of the Ku-band and five times that of the C-band. The wider Ka-bandwidth offers improved anti-interference properties. Small terminal antennas are used with Ka-band communication and the adjacent satellite interference becomes strong, limiting the ...
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. Satellite technology is developing fast, and the applications for satellite technology are increasing all the time.
Ka-band refers to a range of frequencies from 27 GHz to 40 GHz, as defined by IEEE (The Institute of Electrical and Electronics Engineers). The main use of Ka-band is communication with satellites. Satellite communication uplink frequencies are usually around 27 GHz or 31 GHz.
The push toward Ka-band, is not only an opportunity for increased performance, but alleviates current challenges with contentious and cluttered spectrum access in S- and X-band. The paper provides an overview of these advantages and advanced techniques that optimize its use before the transition to optical communications becomes an imperative.
The Near Earth Network (NEN) Initiative for Ka-band Advancement (NIKA) is enhancing direct-to-Earth satellite communications for missions near Earth and out to one million miles away. The NIKA project will establish four new tri-band antennas to significantly increase data rate capabilities for missions in space.
