Satellite Earth Stations and Systems (SES); Harmonised Standard for Earth Stations on Mobile Platforms (ESOMP) transmitting towards satellites in non-geostationary orbit, operating in the 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz frequency bands covering the essential requirements of article 3.2 of the Directive 2014/53/EU

REN/SES-00422

Satelitske zemeljske postaje in sistemi (SES) - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU, za zemeljske postaje na mobilnih platformah (ESOMP), ki oddajajo proti satelitom v negeostacionarni orbiti in delujejo v frekvenčnih pasovih od 27,5 GHz do 29,1 GHz in od 29,5 GHz do 30,0 GHz

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, pri čemer lahko pride do občasnih motenj in prekinitev v satelitski povezavi.
• Zemeljska postaja na mobilni platformi deluje kot del satelitskega omrežja (npr. zvezdnega, mrežnega ali od točke do točke), ki se uporablja za distribucijo in/ali izmenjavo informacij.
• Zemeljska postaja na mobilni platformi je sestavljena iz vse opreme, električne in mehanske, od same antene do vmesnikov z drugo komunikacijsko opremo na mobilni platformi (običajno imenovanih »zemeljski vmesniki«).
• Zemeljska postaja na mobilni platformi je sestavljena iz enega ali več oddajnikov, pri čemer naj bi se pregled sistema na sliki 1 tolmačil v skladu s tem. Zemeljska postaja na mobilni platformi oddaja v frekvenčnem razponu od 27,5 GHz do 29,1 GHz in od 29,5 GHz do 30,0 GHz – to je pas, ki je med drugimi storitvami dodeljen fiksnim satelitskim storitvam (FSS) (Zemlja–vesolje). V okviru nacionalnih predpisov bodo opredeljeni pasovi, ki so na voljo za delovanje zemeljske postaje na mobilni platformi. V okviru teh predpisov se lahko nekateri deli frekvenčnega razpona od 27,5 GHz do 29,1 GHz dodelijo zemeljskim storitvam, kot je fiksna storitev.
Vendar se lahko delovanje zemeljske postaje na mobilni platformi dovoli v skladu z nacionalnimi predpisi v pasu od 29,50 GHz do 30,00 GHz, ker je ta pas primarno dodeljen fiksni satelitski storitvi.
• Zemeljska postaja na mobilni platformi sprejema v eni ali več frekvencah v razponu od 17,30 GHz do 20,20 GHz (fiksne satelitske storitve).
• Zemeljska postaja na mobilni platformi uporablja linearno ali krožno polarizacijo.
• Zemeljska postaja na mobilni platformi deluje prek negeostacionarnih satelitov.
• Zemeljska postaja na mobilni platformi je izdelana za nenadzorovano delovanje.
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.
• Zemeljska postaja na mobilni platformi, ki deluje v pasovih od 27,5 GHz do 28,6 GHz in od 29,5 GHz do 30 GHz: mejne vrednosti EPFD iz člena 22 Pravilnika o radiokomunikacijah Mednarodne telekomunikacijske zveze [i.4] se uporabljajo za zemeljske postaje na mobilni platformi, ki delujejo s sistemom v negeostacionarni orbiti za zaščito omrežij v geostacionarni orbiti (glej št. 22.5D Pravilnika o radiokomunikacijah Mednarodne telekomunikacijske zveze [i.4]).
• Zemeljska postaja na mobilni platformi, ki deluje v pasu od 28,6 GHz do 29,1 GHz: št. 9.11A Pravilnika o radiokomunikacijah Mednarodne telekomunikacijske zveze se uporablja za omrežje v negeostacionarni orbiti zemeljske postaje na mobilni platformi, kar pomeni, da se mora negeostacionarna orbita usklajevati s prej prijavljenimi omrežji v geostacionarni orbiti ali sistemi v negeostacionarni orbiti) (glej št. 5.523A Pravilnika o radiokomunikacijah Mednarodne telekomunikacijske zveze [i.4]).
Ta dokument se uporablja za zemeljsko postajo na mobilni platformi s pomožno opremo in različnimi telekomunikacijskimi vrati, ko ta deluje znotraj mejnih vrednosti obratovalnega okoljskega profila, kot ga z izjavo določi kandidat, ter ko je nameščena v skladu z zahtevami kandidatove izjave ali v skladu z zahtevami dokumentacije uporabnika.
Ta dokument zajema določbe člena 3.2 Direktive 2014/53/EU [i.6] (direktiva RE), kjer je navedeno, da »... mora biti radijska oprema izdelana tako, da optimalno uporablja in podpira učinkovito rabo radijskega spektra z namenom preprečevanja škodljivih motenj«.

Overview

ETSI EN 303 979 V2.1.2 (2016-10) is the harmonised European standard (ETSI EN 303 979 V2.1.2 adopted by SIST) for Earth Stations on Mobile Platforms (ESOMP) transmitting to satellites in non‑geostationary orbit (NGSO). It covers ESOMPs operating in the uplink bands 27.5–29.1 GHz and 29.5–30.0 GHz and receiving in 17.30–20.20 GHz (Fixed Satellite Service, FSS). The standard is intended to demonstrate compliance with the essential requirement of Article 3.2 of Directive 2014/53/EU (efficient use of the radio spectrum to avoid harmful interference).

Key topics and technical requirements

The standard focuses on spectrum protection, system behaviour and conformance tests for mobile and stationary ESOMPs, including:

• Frequency and regulatory context

  • Uplink: 27.5–29.1 GHz and 29.5–30.0 GHz (national allocation and FSS specifics apply).
  • Downlink: 17.30–20.20 GHz (FSS).
  • References to ITU Radio Regulations (epfd limits, coordination requirements such as No. 22.5D and No. 9.11A).

• Antenna and emission controls

  • Off‑axis and on‑axis spurious radiation limits and test methods.
  • Antenna pointing accuracy, polarization alignment (linear or circular) and on‑axis cross‑polarization isolation.
  • Receive antenna off‑axis gain pattern requirements.

• Power and interference management

  • epfd (equivalent power flux density) limits for protection of GSO networks.
  • Uplink power control, EIRP considerations and carrier suppression.

• Control, monitoring and safety

  • Control and Monitoring Functions (CMFs): states, processor and transmit subsystem monitoring, control/response channels.
  • Requirements for cessation of emissions, fault handling and identification of the ESOMP.
  • Initial burst transmission rules, inhibition of transmissions and power‑on/reset behaviours.

• Operational scope and conformance

  • Applies within declared environmental/operational profiles and installation conditions.
  • The Network Control Facility (NCF) function is described but is outside the scope for this document’s conformance testing.

Practical applications - who uses this standard

• Manufacturers and integrators of satellite terminals for trains, ships, aircraft and road vehicles - to design ESOMPs that meet spectrum‑use and interference protections.
• Network operators and service providers deploying NGSO satellite networks and ESOMP fleets.
• Test laboratories and certification bodies performing conformance testing for CE marking under Directive 2014/53/EU (RE Directive).
• Regulators and spectrum managers assessing national authorisation and cross‑service coexistence (FSS vs terrestrial services).

Related standards and notes

• This harmonised EN covers Article 3.2 of the RE Directive; other ENs may apply for additional essential requirements under other parts of Article 3.
• Relevant normative references include ITU Radio Regulations and ECC/ national operational requirements. National regulations may further restrict available bands (e.g., terrestrial allocations in parts of 27.5–29.1 GHz).

Annex B (informative) provides information on Linear Polarization Alignment Error Calculation.
Annex C (normative) provides specifications concerning radiated measurements.
Annex D (normative) provides specifications concerning conducted measurements.
Annex E (informative) provides general information concerning RF cables.
Annex F (informative) provides information concerning RF waveguides.
Annex G (informative) covers other supplementary information.
The present document is intended to cover the provisions of Directive 2014/53/EU [i.8] (RE Directive) article 3.2 which
states that "….radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio

effectively and supports the efficient use of radio spectrum, radio equipment should be constructed so that: in the case
of a transmitter, when the transmitter is properly installed, maintained and used for its intended purpose it generates
radio waves emissions that do not create harmful interference, while unwanted radio waves emissions generated by the
transmitter (e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be
limited to such a level that, according to the state of the art, harmful interference is avoided; and, in the case of a
receiver, it has a level of performance that allows it to operate as intended and protects it against the risk of harmful
interference, in particular from shared or adjacent channels, and, in so doing, supports improvements in the efficient
use of shared or adjacent channels."
Recital 11 of Directive 2014/53/EU [i.8] states that "although receivers do not themselves cause harmful interference,
reception capabilities are an increasingly important factor in ensuring the efficient use of radio spectrum by way of an
increased resilience of receivers against harmful interference and unwanted signals on the basis of the relevant
essential requirements of Union harmonisation legislation."
As a consequence, the present document includes both transmitting and receiving parameters aiming to maximize the
efficient use of radio spectrum.

Figure 1: ESOMP System Overview
• 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
and, therefore, may be subject to occasional disturbances and interruptions in the satellite link.
• The ESOMP is operating as part of a satellite network (e.g. star, mesh or point-to-point) used for the
distribution and/or exchange of information.
• The ESOMP is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on a mobile platform (usually referred to as the terrestrial
interface).
• The ESOMP comprises of one or more emitters and the system overview given in figure 1 should be
interpreted accordingly.
• The transmit and receive frequencies are shown in table 1.
Table 1: Frequency bands
Frequency Bands/frequencies
Transmit (Earth-to-space) 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz
Receive (space-to-Earth) 17,30 GHz to 20,20 GHz

• The ESOMP transmits within the frequency range from 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz,
which is a band allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. National
regulations will specify the bands available for the operation of the ESOMP. Such regulations may designate
some parts of the frequency range 27,5 GHz to 29,1 GHz to terrestrial services such as the Fixed Service.
However, the operation of the ESOMP may be permitted under national regulations in the 29,50 GHz to
30,00 GHz band since this band is allocated on a primary basis to the Fixed Satellite Service.
• The ESOMP receives in one or more f

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio equipment within the scope of the Directive 2014/53/EU [i.8]. The modular structure is shown in ETSI
EG 201 399 [i.2].
The present document is largely based on ETSI EN 303 978 [i.5], for ESOMPs operating with GSO satellites.
The present document may also be applicable to the frequency bands 30,0 GHz to 31,0 GHz (Earth-to-space) and
20,2 GHz to 21,2 GHz (space-to-Earth) subject to national regulation.

Annex A (normative) provides HS Requirements specifications.
Annex B (informative) provides information on Linear Polarization Alignment Error Calculation.
Annex C (normative) provides specifications concerning radiated measurements.
Annex D (normative) provides specifications concerning conducted measurements.
Annex E (informative) provides general information concerning RF cables.
Annex F (informative) provides information concerning RF waveguides.
Annex G (informative) covers other supplementary information.
The present document is intended to cover the provisions of Directive 2014/53/EU [i.8] (RE Directive) article 3.2 which
states that "….radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio
spectrum in order to avoid harmful interference".
Recital 10 of Directive 2014/53/EU [i.8] states that "in order to ensure that radio equipment uses the radio spectrum
effectively and supports the efficient use of radio spectrum, radio equipment should be constructed so that: in the case
of a transmitter, when the transmitter is properly installed, maintained and used for its intended purpose it generates
radio waves emissions that do not create harmful interference, while unwanted radio waves emissions generated by the
transmitter (e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be
limited to such a level that, according to the state of the art, harmful interference is avoided; and, in the case of a
receiver, it has a level of performance that allows it to operate as intended and protects it against the risk of harmful
interference, in particular from shared or adjacent channels, and, in so doing, supports improvements in the efficient
use of shared or adjacent channels."
Recital 11 of Directive 2014/53/EU [i.8] states that "although receivers do not themselves cause harmful interference,
reception capabilities are an increasingly important factor in ensuring the efficient use of radio spectrum by way of an
increased resilience of receivers against harmful interference and unwanted signals on the basis of the relevant
