Hi,welcome to www.freestandardsdownload.com,today i share ETSI EN 303 980 V1.1.1(2017-12) for you ,you can download it free.Part of this standard is described as follows:
The present document specifies technical characteristics and methods of measurements for fixed and in-motion Earth
Stations communicating with non-geostationary satellite systems (NEST)in the 11 GHz to 14 GHz FSS frequency
bands, which have the following characteristics
The NEST is designed for both in-motion and stationary operation
The NEST operates in-motion on various platforms such as trains, maritime vessels, aircraft and other vehiclesand, therefore, may be subject to occasional disturbances and interruptions in the satellite link
The NEST is operating as part of a satellite system used for the provision of broadband communications
The NEST is comprised of all the equipment, electrical and mechanical, from the antenna itself to the interfacewith other communications equipment on a mobile platform
The NEST comprises one or more emitters and the system overview as given in figure 1 should be interpretedaccordingly
The transmit and receive frequencies are shown in table 1
The NEST transmits within the frequency range from 14,0 GHz to 14, 50 GHz
The NEST receives within the range from 10.70 GHz to 12. 75 ghzThe NEST transmits at elevation angles of 50 or greater, relative to the horizontal plane
The NEST uses linear or circular polarization
The NEST communicates with non-geostationary satellites
The NEST is designed for unattended operation
The NEST is controlled and monitored by a Network Control Facility (NCF)。 The NCF is outside the scope of the present document
