(Main)Satellite Earth Stations and Systems (SES) - Earth Stations on Mobile Platforms (ESOMP) communicating with satellites in geostationary orbit, operating in the 27,5 GHz to 30,0 GHz and 17,3 GHz to 20,2 GHz frequency bands - Harmonised Standard for access to radio spectrum
Satellite Earth Stations and Systems (SES) - Earth Stations on Mobile Platforms (ESOMP) communicating with satellites in geostationary orbit, operating in the 27,5 GHz to 30,0 GHz and 17,3 GHz to 20,2 GHz frequency bands - Harmonised Standard for access to radio spectrum
The present document specifies technical characteristics and methods of measurements for Earth Stations on Mobile
Platforms (ESOMP) equipment with the following characteristics:
• The ESOMP is designed for both mobile and stationary operation.
• The ESOMP operates on various mobile platforms such as trains, maritime vessels, aircraft and other vehicles.
• The ESOMP is controlled and monitored by a Network Control Facility (NCF). This function may be
performed centrally (e.g. for a network of ESOMPs with a central hub) or it could be performed within the
ESOMP for autonomous control. The NCF is outside the scope of the present document.
• The ESOMP transmit and receive frequencies are shown in table 1.
NOTE: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.11] is given in annex A.
Satelitske zemeljske postaje in sistemi (SES) - Zemeljske postaje na mobilnih platformah (ESOMP), ki komunicirajo s sateliti v geostacionarni orbiti in delujejo v frekvenčnih pasovih od 27,5 GHz do 30,0 GHz in od 17,3 GHz do 20,2 GHz - Harmonizirani standard za dostop do radijskega spektra
Ta dokument določa tehnične lastnosti in merilne metode za opremo zemeljskih postaj na mobilnih platformah (ESOMP) z naslednjimi značilnostmi:
• Zemeljska postaja na mobilni platformi je izdelana za mobilno in stacionarno delovanje.
• Zemeljska postaja na mobilni platformi deluje na različnih mobilnih platformah, npr. na vlakih, morskih plovilih, letalih in drugih vozilih.
• Zemeljska postaja na mobilni platformi se krmili in spremlja z napravo za krmiljenje omrežja (NCF). Ta funkcija se lahko izvaja centralno (npr. za omrežje zemeljskih postaj na mobilni platformi s centralnim vozliščem) ali pa se lahko izvaja v sami zemeljski postaji na mobilni platformi za avtonomno krmiljenje. Naprava za krmiljenje omrežja ne spada na področje uporabe tega dokumenta.
• Frekvence oddajanja in sprejemanja zemeljske postaje na mobilni platformi so prikazane v preglednici 1.
OPOMBA: Razmerje med tem dokumentom in bistvenimi zahtevami iz člena 3.2 Direktive 2014/53/EU [i.11] je podano v dodatku A.
