Satellite Earth Stations and Systems (SES); Transmit-only or transmit-and-receive Very Small Aperture Terminals (VSATs) used for communications operating in the Fixed Satellite Service (FSS) 11/12/14 GHz frequency bands
Revision of Edition 1 (Dec. 1992) of the standard in light of - the Change Requests received by SES/SES 2 - the now available Satellite Terminal Equipment Directive - the now available EMC Directive - the VSAT Testing ETSs (ETS 300 456) now in PE. Ed 2 of this ETS should be aligned with the PE results of the VSAT Testing ETS 300 456 (Jan/Feb 1995) This ETS will provide the general requirements for the RF/IF characteristics of earth stations operating in bidirectional ( two way ) VSAT systems for data communications in the Fixed Satellite Service (FSS).

Page 7ETS 300 159: September 19961ScopeThis European Telecommunication Standard (ETS) provides specifications for the standardisation of thecharacteristics of transmit-only or transmit-and-receive Very Small Aperture Terminals (VSATs) operatingas part of a satellite network (e.g. star, mesh or point-to-point) used for the distribution and/or exchange ofinformation between users.In such a network a Centralised Control and Monitoring Function (CCMF) is responsible for the monitoringand control of VSATs.These VSATs have the following characteristics:-operating in the exclusive part of the Ku-band allocated to the Fixed Satellite Services (FSS), 14,00to 14,25 GHz (Earth-Space), 12,50 to 12,75 GHz (Space-Earth), and/or in the shared parts of theKu-band, allocated to the FSS and Fixed Services (FS), 14,25 to 14,50 GHz (Earth-Space) and/or10,70 to 11,70 GHz (Space-Earth);-in these frequency bands linear polarization is normally used and the system operates throughsatellites at 3° spacing;-designed usually for unattended operation;-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 theantenna sub-system and associated power amplifier and 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 applies to the VSAT with its ancillary equipment and its various terrestrial ports, and operatedunder the conditions which are within the ranges of humidity, temperature and supply voltage declared bythe manufacturer.EMC specifications are contained in ETS 300 673 [3].This ETS does not contain any specification or information on the installation of the VSATs.The specifications have been selected to ensure an adequate level of compatibility for VSATs. The levels,however, do not cover extreme cases which may occur in any location but with a low probability ofoccurrence. In such a case it may be necessary to use special protection supplied to either the source ofinterference, or the interfered part or both.This ETS deals with two types of specification:-specifications defined in order to protect other users of the frequency spectrum, both satellite andterrestrial, from unacceptable interference. In addition, these specifications are specified for thepurposes of structural safety and lightning protection as well as protection from harmfulinterference;-specifications related to characteristics which contribute to the quality of reception by providing theVSAT with minimum interference protection from other radio systems. These specifications apply ifrequired by the manufacturer.SIST ETS 300 159:2000

Page 9ETS 300 159: September 1996ancillary equipment: Equipment used in connection with a VSAT is considered as ancillary if the threefollowing conditions are met:a)the equipment is intended for use in conjunction with a VSAT to provide additional operationaland/or control features (e.g. to extend control to another position or location); andb)the equipment cannot be used on a stand alone basis, to provide user functions independently of aVSAT; andc)the absence of the equipment does not inhibit the operation of the VSAT.nominated bandwidth: The bandwidth of the VSAT radio frequency transmission nominated by themanufacturer. The nominated bandwidth is wide enough to encompass all spectral elements of thetransmission which have a density greater than the specified spurious levels and to take account of thetransmit carrier frequency stability.NOTE 2:This definition is chosen to allow flexibility regarding adjacent channel interferencelevels which will be taken into account by operational procedures depending on theexact transponder carrier assignment situation.spurious radiation: Any radiation outside the nominated bandwidth.cross-polarization discrimination: The ratio of the on-axis co-polar gain to the cross-polar gain in agiven direction, at a transmit or receive frequency.
