适用范围

"This European Telecommunication Standard (ETS) provides specifications for the standardisation of the characteristics of receive-only Very Small Aperture Terminals (VSATs) operating as part of a satellite network used for the distribution of data. These VSATs have the following characteristics: - operating in the exclusive space-to-earth part of the Ku-band allocated to the Fixed Satellite Service (FSS)@ 12@50 to 12@75 GHz and the shared parts of the Ku-band@ allocated to FSS and the Fixed Service (FS)@ 10@7 to 11@7 GHz; - designed for unattended operation; - limited to reception of baseband digital signals; - equipped with one or several terrestrial output ports; - antenna diameter not exceeding 3@8 m or equivalent corresponding aperture. The equipment considered in this ETS comprises both the ""outdoor unit""@ usually composed of the antenna subsystem and associated Low Noise Block (LNB)@ and the ""indoor unit"" composed of the remaining part of the communication chain@ including the cable between these two units. This ETS does not contain any requirement@ recommendation or information about the installation of the VSATs. Nor is this ETS intended to apply to VSAT network hub stations. This ETS deals with two types of specification: a) Essential normative requirements (indicated in Clause 4) Requirements are specified in order to protect other users of the frequency spectrum@ both satellite and terrestrial@ from unacceptable interference. In addition requirements are specified for the purposes of electrical safety@ structural safety and solar radiation protection as well as protection from harmful interference. The test and measurement procedures associated with the normative requirements detailed in Clause 4 of this ETS shall be met in order to qualify compliance with this ETS. b) Recommendations (indicated in Clause 5) Recommendations are related to characteristics which contribute to the quality of reception by providing the VSAT with a minimum interference protection from other radio systems. The test and measurement procedures associated with the informative recommendations detailed in Clause 5 of this ETS are given for verification purposes only. The compliance with the recommendation will not be taken as a condition to comply with this ETS. All tests related to the requirements shall be performed and the results shall be entered in the data sheet of the test report. The ability to comply with the recommendations shall also be noted in the data sheet of the test report."
