Overview

SIST EN 303 980 V1.3.1:2023, developed by the Slovenian Institute for Standardization (SIST), defines harmonized requirements for fixed and in-motion Earth Stations communicating with non-geostationary satellite systems (NEST) within the 11 GHz to 14 GHz frequency bands. This standard ensures that NESTs-used on stationary installations, vehicles, trains, ships, and aircraft-can reliably and efficiently access radio spectrum for broadband communications, complying with European regulatory frameworks like Directive 2014/53/EU.

Satellite Earth Stations and Systems (SES) covered by this document include all relevant equipment from antenna to communication interfaces that enable high-capacity satellite connectivity for both fixed and mobile environments across Europe and globally. The standard specifies the necessary technical characteristics and measurement methods to ensure safe, robust, and interference-resistant operation.

Key Topics

• Scope of Operation:

  • Both stationary and in-motion use across a variety of platforms (vehicles, trains, ships, aircraft).
  • Supports broadband communication via non-geostationary satellite networks.
  • Covers NESTs operating inside 10.70 GHz to 12.75 GHz (receive) and 14.00 GHz to 14.50 GHz (transmit).
  • Utilizes linear or circular polarization techniques.

• Technical Requirements:

  • Detailed conformance requirements for spectrum access.
  • Precise methods for measuring off-axis and on-axis spurious emissions.
  • Specifications for antenna beam pointing accuracy and error detection.
  • Defined operational states and behaviors for managing transmission cessation under fault or control conditions.

• Operational Considerations:

  • Designed for unattended, remote-controlled operation via a Network Control Facility (NCF).

Recital 10 of Directive 2014/53/EU [i.6] 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.6] 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 o

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 and telecommunications terminal equipment within the scope of the RE Directive [i.6]. The modular
structure is shown in ETSI EG 201 399 [i.2].
The present document is largely based on ETSI EN 303 979 [i.4], for ESOMPs operating with NGSO satellites.
The present document may also be applicable to the frequency band 14,0 GHz to 14,50 GHz (Earth-to-space) and
10,70 GHz to 12,75 GHz (space-to-Earth) subject to national regulation.
Annex A (informative) provides HS Requirements specifications.
Annex B (normative) describes methods of taking radiated measurements.
Annex C (normative) describes methods of taking conducted measurements.
Annex D (informative) describes requirements for RF measurement cables.
Annex E (informative) describes use of RF waveguides.
Annex F (informative) describes measurement equipment.
Annex G (informative) describes the applicability of parameters in ETSI EG 203 336 [i.7].
Annex H (informative) Bibliography covers other supplementary information.
Recital 10 of Directive 2014/53/EU [i.6] 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.6] 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 r
