Sistemet dhe Stacionet Satelitore në Tokë (SES); EN i harmonizuar për Stacionet Tokësore me satelit të Lëvizshme në Tokë (LMES) me vlera të Ulëta të të dhënave që punojnë në bandën e frekuencave 11/12/14 GHz që mbulon kërkesat thelbësore nën artikullin 3.2 të direktivës R&TTE

Satellite Earth Stations and Systems (SES); Harmonized EN for Low data rate Land Mobile satellite Earth Stations (LMES) operating in the 11/12/14 GHz frequency bands covering essential requirements under article 3.2 of the R&TTE directive

Scope

The present document applies to Land Mobile Earth Stations (LMESs) which have the following characteristics:
- the LMES are operating in one or more frequency ranges of the Fixed Satellite Service (FSS):
- 10,70 GHz to 11,70 GHz (space to earth);
- 12,50 GHz to 12,75 GHz (space to earth);
- 14,00 GHz to 14,25 GHz (earth to space).
Because the transmissions from the LMES to the Satellite in the 14,00 GHz to 14,25 GHz band fall under a
secondary allocation, the transmissions should not cause harmful interference to primary services (e.g. the Fixed
Satellite Service (FSS)) and at the same time cannot claim protection from harmful interference from those
services.
- the LMES could be either vehicle mounted or portable equipment;
- the LMES could consist of a number of modules including a keyboard interface to the user;
- the LMES use linear polarization;
- the LMES 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 antenna of the LMES may be omnidirectional or directional with a means of tracking the satellite;
- the LMES are operating as part of a satellite network used for the distribution and/or exchange of information
between users;
- the LMES are 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 LMES with its ancillary equipment and its various terrestrial ports, and when
operated within the boundary limits of the operational environmental profile declared by the applicant.
The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) [1]
Article 3.2, which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated
to terrestrial/space radio communications and orbital resources so as to avoid harmful interference.".
In addition to the present document, other ENs that specifies technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the ETSI web site.
