The present document specifies technical characteristics and methods of measurement in respect of ElectroMagnetic Compatibility (EMC) for the following radar systems: • Fixed and ground based monostatic aeronautical Primary Surveillance Radar (PSR) and Surface Movement Radar (SMR) • Fixed and ground based monostatic meteorological radar system, for example weather radar systems or wind profiler with the following characteristics: • operating in at least one of the frequency ranges as shown in table 1; • operated only by AC power. The above mentioned radio equipment is intended to be used at a fixed location (permanent or temporarily) and is equipped with rotating passive antennas. A radar system consists of one or more enclosures that contain at least the following radar functionalities: transmitter, receiver, signal processing. Other parts which are not part of the radar functionality e.g. local UPS, air conditioning equipment, dehumidifying equipment, communication network equipment, etc., are not in the scope of the present document, unless these parts are implemented inside the radar system enclosure(s). Table 1: Frequency range of fixed ground based aeronautical and meteorological radar systems Operating frequency ranges 1 215 MHz to 1 400 MHz 2 700 MHz to 3 100 MHz 5 250 MHz to 5 850 MHz 8 500 MHz to 10 500 MHz Technical specifications related to the antenna port of the radio equipment are not included in the present document. Such technical specifications are found in the relevant product standards under article 3.2 of Directive 2014/53/EU [i.1]. Emission requirements in the present document are specified for frequencies above 9 kHz. The environmental classification and the emission and immunity requirements used in the present document are as stated in ETSI EN 301 489-1 [1], except for any special conditions included in the present document. NOTE: The relationship between the present document and essential requirements of article 3.1(b) of Directive 2014/53/EU [i.1] is given in annex A.

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 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 transmits at elevation angles of 35° or greater, relative to the horizontal plane. • The NEST receives within the range from 10,70 GHz to 12,75 GHz. • 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. The present document applies to the NEST with its ancillary equipment and its various telecommunication ports, and when operated within the boundary limits of the operational environmental profile as declared by the manufacturer and when installed as required by the manufacturer's declaration or in the user documentation.

The present document specifies technical characteristics and methods of measurements for fixed and in-motion Earth Stations communicating with non-geostationary satellite systems (WBES) in the 11 GHz to 14 GHz FSS frequency bands, which have the following characteristics: • The WBES is further defined as one of two classes of Earth stations, class A and class B. The clauses in the present document apply to both classes unless separately delineated. • The WBES is designed for both in-motion and stationary operation. • The WBES 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 WBES is operating as part of a satellite system used for the provision of broadband communications. • The WBES 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 WBES comprises one or more emitters and the system overview as given in figure 1 should be interpreted accordingly. • The transmit and receive frequencies are shown in table 1. • The WBES transmits within the frequency range from 14,0 GHz to 14,50 GHz. • The WBES receives within the range from 10,70 GHz to 12,75 GHz. • The Class A WBES transmits at elevation angles of 35° or greater, relative to the horizontal plane. • The Class B WBES transmits at elevation angles of 25° or greater, relative to the horizontal plane. • The WBES uses linear or circular polarization. • The WBES communicates with non-geostationary satellites. • The WBES is designed for unattended operation. • The WBES is controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the present document. The present document applies to the WBES with its ancillary equipment and its various telecommunication ports, and when operated within the boundary limits of the operational environmental profile as required by its intended use and when installed as required by the intended use or in the user documentation.
