Foreword
This Technical Basis for Regulation (TBR) has been produced by the Satellite Earth Stations and Systems
(SES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
Introduction
The SES Directive [1] which supplements the TTE Directive [2] concerns the harmonization of conditions
for the placing on the market of such equipment.
Two classes of standards are applicable to satellite earth station equipment. European
Telecommunication Standards (ETSs) give the full technical specifications for this equipment, whereas
Technical Bases for Regulation (TBRs) give the essential requirements under the SES Directive [1] and
the TTE Directive [2] for placing such equipment on the market. Receive-only equipment, not intended for
terrestrial connection to the public telecommunications network, may be put into use. Nothing in this TBR
is construed to prevent the use of Community internal production control procedures as set out in the
annexes to the two Directives for such receive-only equipment. This TBR is based on ETS 300 327 (see
annex C, Bibliography).

1 Scope
This Technical Basis for Regulation (TBR) specifies the technical requirements that apply to Satellite
News Gathering (SNG) Transportable Earth Stations (TESs) for compliance with Articles 4.1 and 4.3 of
the SES Directive [1].
These SNG TESs have the following characteristics:
The SNG TESs are designed for Satellite News Gathering (SNG) which can be either an
unforeseen or pre-planned activity.
SNG TES is capable of transmitting television signals and associated audio or programme audio
only towards a satellite positioned on the geostationary orbit. The modulation method may be either
analogue or digital. Such transmissions are point-to-point or point-to-multipoint but not for general
broadcast reception.
The SNG TESs are designed for relocation at any time to a different fixed operating location but are
not intended to operate during the relocation period. The SNG TESs can be either vehicle mounted
or packed for transportation. The SNG TESs considered in this TBR are those designed to operate
whilst stationary.
The SNG TESs are operating in the following bands allocated to the Fixed Satellite Services (FSS):
- 10,70 GHz to 11,70 GHz (space-to-earth);
- 12,50 GHz to 12,75 GHz (space-to-earth);
- 12,75 GHz to 13,25 GHz (earth-to-space);
- 13,75 GHz to 14,25 GHz (earth-to-space);
- 14,25 GHz to 14,50 GHz (earth-to-space).
Frequencies could be selected from through the entire frequency range or be restricted to a range
completely enclosed within those bands. These bands are partly shared between FSS and Fixed
Service (FS).
At present the ITU Radio Regulations [5] restrict the use of the 13,75 GHz to 14,00 GHz band to
earth stations having an antenna diameter of 4,5 m or greater and having a transmitting EIRP
between 68 dBW and 85 dBW.
The SNG TESs use linear polarization.
The SNG TESs operate through a geostationary satellite at least 3° away from any other
geostationary satellite operating in the same frequency band and covering the same area.
The SNG TES antenna diameter does not exceed 5 m, or equivalent corresponding aperture.
The SNG TESs are designed for attended operation.
This TBR applies to the SNG TES with its ancillary equipment and its various terrestrial ports, and
operated under the conditions which are within the ranges of humidity, temperature and supply voltage
declared by the manufacturer.
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.
This TBR 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.
This TBR does not contain any requirement, recommendation or information about the installation of the
SNG TESs. Compliance of a SNG TES to the requirements of this TBR does not imply compliance to any
requirement related to the use of the SNG TES (e.g. licensing requirements).

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this TBR, the following definitions apply:
carrier-off state: That state where the SNG TES is electrically powered and is not transmitting a signal.
NOTE 1: A SNG TES is considered to be in the carrier-off state when one of the following
conditions is satisfied:
- the High Power Amplifier (HPA) is in standby mode;
- the transmit subsystem is not switched to the antenna.
carrier-on state: That state where the SNG TES is transmitting a signal.
cross-polarization discrimination: The ratio of the on-axis co-polar gain to the cross-polar gain in a
given direction, at a transmit or receive frequency. It is usually expressed in dB.
exclusion band: The exclusion band is centred on the transmit frequency and is equal to 5 times the
occupied bandwidth.
manufacturer: The legal entity responsible under the terms of Council Directive 93/97/EEC
(SES Directive) [1] for placing the product on the market in a member state.

occupied Bandwidth (Bo): For a digital modulation scheme the width of the signal spectrum 10 dB
below the maximum inband density. For an analogue modulation scheme the occupied bandwidth (Bo) is
defined as follows:
B = ΔF + 2f

ΔF = peak-to-peak frequency deviation of the TV-carrier for a 1 V peak-to-peak test tone at the
pp
pre-emphasis network cross-over frequency in Hz; and
fm = top video baseband frequency (e.g. 5 MHz).
Satellite News Gathering Transportable Earth Station (SNG TES): Equipment capable of transmitting
television signals and associated audio or programme audio only towards a satellite positioned on the
geostationary orbit. The modulation method may be either analogue or digital. Such transmissions are
point-to-point or point-to-multipoint but not for general broadcast reception.
The SNG TES usually comprises the main parts, as defined below, and all power, interconnecting and
other cables required for proper operation of the equipment as follows:
1) the antenna subsystem, which converts the incident electromagnetic wave into a guided wave and
vice versa and which includes any mounting that may be required;
2) the transmit subsystem, which is composed of the frequency translation equipment and the high
power amplifier;
3) the receive subsystem, which consists of the low noise amplifier and the frequency translation
equipment;
4) the ground communications subsystem, which consists of modulation and demodulation equipment,
either analogue or digital, and associated baseband equipment;
5) the monitoring and control subsystem which consists of test equipment together with a transmitter
identification system if implemented;
6) the communications subsystem which consists of and a facility for two way communication if
implemented;
7) the power subsystem, which consists of any power generation equipment that may be required;
8) the transportation subsystem, which consists of either a vehicle for vehicle mounted SNG TES or
flight cases for "flyaway" SNG TES.
spurious radiation: Any radiation outside the exclusion band.
transmit frequency band: One of the following frequency bands, or a part of them, within which the SNG
TES is able to transmit its carrier:
12,75 GHz to 13,25 GHz;
13,75 GHz to 14,50 GHz.
The transmit frequency bands of the SNG TES are declared by the manufacturer.
NOTE 2: An SNG TES may be designed for several transmit frequency bands.
