Satellite Earth Stations and Systems (SES); Harmonised Standard for fixed and in-motion Earth Stations communicating with non-geostationary satellite systems (NEST) in the 11 GHz to 14 GHz frequency bands covering essential requirements of article 3.2 of Directive 2014/53/EU

scope:
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 vehicles and, 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 interface with 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 interpreted accordingly.
• 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 GHz.
• The 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.
