Satellite Earth Stations and Systems (SES); Harmonised Standard for Very Small Aperture Terminal (VSAT); Transmit-only, transmit-and-receive, receive-only satellite earth stations operating in the 4 GHz and 6 GHz frequency bands covering the essential requirements of article 3.2 of the Directive
卫星地面站和系统;甚小孔径终端(VSAT)协调标准;仅发射、发射和接收、仅接收在4 GHz和6 GHz频段运行的卫星地面站 涵盖本指令第3.2条的基本要求
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio equipment within the scope of the RE Directive [6]. The modular structure is shown in ETSI
EG 201 399 [i.1].The determination of the parameters of the user earth stations using a given geo-stationary satellite for the protection of
the spectrum allocated to that satellite is considered to be under the responsibility of the satellite operator or the satellite
network operators. For this reason the requirement on the cross polarization discrimination which was in ETSI
TBR 043 [i.3] has not been copied in the present document and inter-modulation limits inside the band 5,850 GHz to
7,075 GHz are to be determined by system design and are subject to satellite operator specifications.The requirements have been selected to ensure an adequate level of compatibility with other radio services. The levels,
however, do not cover extreme cases which may occur in any location but with a low probability of occurrence.
The present document may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or broadcast site in the
near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference, or
the interfered part or both.The present document does not contain any requirement, recommendation or information about the installation of the
VSAT.All parts of the indoor unit related to reception, processing and presentation of the received information except the
control channel are not within the scope of the present document. The syntax of the control channel messages is outside
the scope of the present document.
