ETSI - EN 302 186
Satellite Earth Stations and Systems (SES); Harmonized EN for satellite mobile Aircraft Earth Stations (AESs) operating in the 11/12/14 GHz frequency bands covering essential requirements under article 3.2 of the R&TTE directive
|Publication Date:||1 April 2003|
The present document specifies certain minimum technical performance requirements of Aircraft Earth Station (AES) equipment with both transmit and receive capabilities for provision of aeronautical mobile satellite service, in the frequency bands
The AES has the following characteristics:
- These AESs are equipment for installation on aircraft.
- The AES could consist of a number of modules from the antenna subsystem to the user interfaces.
- The AES uses linear polarization.
- The AES system uses digital modulation.
- The AES operates through a GSO 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 AES is directional, with means of tracking the satellites, which can be achieved by using either an active phase array or reflective type configuration.
- These AESs are operating as part of a satellite network used for the distribution and/or exchange of information between users.
- These AESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the present document.
The technical requirements in the present document are in two major categories:
- emission limits: to protect other radio services and systems from harmful interference generated by the AES in normal use;
- AES Control and Monitoring Functions (CMF): to protect other radio services and systems from unwanted transmissions from the AES. The CMF in each AES is capable of answering to commands from the Network Control Facility (NCF) for its supporting satellite network.
The present document applies to the AESs with their ancillary equipment and its various ports, and when operated within the boundary limits of the operational environmental profile declared by the manufacturer.
The present document is intended to cover the provisions of Directive 1999/5/EC (R&TTE Directive) [i] 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 special technical requirements in respect of essential requirements under other parts of article 3 of the R&TTE Directive [i] may apply to equipment within the scope of the present document.
NOTE: A list of such ENS is included on the web site
The present document does not cover equipment compliance with relevant civil aviation regulations. Furthermore, an AES and its installation on board aircraft are subject to additional national or international civil aviation airworthiness certification requirements.
