Overview

oSIST prEN 301 443 V2.2.0:2026 is a harmonised European standard published by SIST, prepared by the ETSI Technical Committee Satellite Earth Stations and Systems (SES). This standard defines the essential technical requirements and test methods for Very Small Aperture Terminal (VSAT) satellite earth stations that operate in the 4 GHz and 6 GHz frequency bands. The standard applies to transmit-only, transmit-and-receive, and receive-only VSAT earth stations, providing a consistent framework for achieving compliance with European regulations for radio equipment, specifically under Directive 2014/53/EU (RED).

By addressing radio spectrum access and electromagnetic compatibility for satellite stations, this standard is critical for manufacturers, network operators, and regulatory bodies involved with the design, deployment, and control of VSAT installations in Europe.

Key Topics

• Technical Requirements: The standard includes detailed specifications for the operational performance of VSAT equipment, such as limitations on spurious emissions, off-axis e.i.r.p. (Equivalent Isotropically Radiated Power) emission density, and adjacent signal selectivity.
• Conformance Testing: It sets out unified measurement and test methods to verify compliance with the essential requirements, helping manufacturers and integrators demonstrate conformity.
• Centralized Control and Monitoring Functions: Requirements are included for both Class A and Class B centralized control systems used to monitor and manage VSAT states, transmit subsystems, and processor functions.
• Environmental Considerations: Guidance on environmental profile and test conditions ensures VSAT equipment is robust and reliable in diverse operational environments.
• Antenna Specifications: There are standards for antenna pointing stability, gain patterns, and blocking performance, vital for minimizing interference with other radio equipment and networks.

Applications

VSAT satellite earth stations are widely used in a range of sectors for reliable satellite communications, such as:

• Enterprise Networks: Providing data, voice, and video connectivity to remote branches and offices.
• Backhaul Services: Supporting mobile network operators to link remote base stations with core networks.
• Emergency Communications: Enabling critical communications infrastructure during disaster recovery or in areas without terrestrial coverage.
• Maritime and Transport: Delivering connectivity to vessels, aircraft, and vehicles where terrestrial solutions are unavailable.
• Broadband Access: Supplying internet connectivity to rural and underserved regions.

By adhering to this harmonised standard, equipment manufacturers and operators ensure regulatory acceptance and interoperability across the European market, reducing deployment risks and ensuring protection against interference.

Related Standards

Organizations working with VSAT systems and satellite ground stations should also consider the following related standards and directives:

• ETSI EN 303 979: Harmonised standard for satellite earth stations in different frequency bands.
• ETSI EN 301 444: Covers satellite earth stations for fixed-satellite services.
• ETSI EN 303 372: Specifies essential requirements for earth stations on ships.
• Directive 2014/53/EU (RED): European regulatory framework for radio equipment.
• ITU Radio Regulations: International rules from the International Telecommunication Union regarding spectrum management and satellite communications.

These related documents create a comprehensive regulatory and technical landscape for satellite equipment manufacturers, service providers, and regulators, supporting the consistent deployment and operation of VSAT infrastructure.

Terminal (VSAT) equipment which has the following characteristics:
• the VSAT is operating in one or more frequency ranges within the following bands allocated to the Fixed
Satellite Service (FSS), shared with other services, e.g. the Fixed Service (FS) and the Mobile Service (MS):
- 5,850 GHz to 7,075 GHz (Earth-to-space);
- 3,400 GHz to 4,200 GHz (space-to-Earth);
- 4,500 GHz to 4,800 GHz (space-to-Earth);
• the VSAT uses linear or circular polarization;
• the VSAT operates through a geostationary satellite at least 2° away from any other geostationary satellite
operating in the same frequency band and covering the same area;
• the VSAT antenna diameter does not exceed 7,3 m, or equivalent effective area;
• the VSAT is either:
- a transmit-only VSAT: designed for transmission-only of radio-communications signals in the frequency
band (earth-to-space) specified in the present clause; or
- a transmit-and-receive VSAT: designed for transmission-and-reception of radio-communications signals
in the frequency bands specified in the present clause; or
- a receive-only VSAT: designed for reception-only of radio-communications signals in the frequency
band (space-to-Earth) specified in the present clause;
• the VSAT is designed for unattended operation;
• the VSAT 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 between users; the VSAT is controlled, and monitored for the transmit
functionality, by a Centralized Control and Monitoring Facility (CCMF). The VSAT has to implement Control

1 Scope
The present document specifies technical characteristic and methods of measurements for Very Small Aperture
Terminal (VSAT) equipment which has the following characteristics:
• the VSAT is operating in one or more frequency ranges within the following bands allocated to the Fixed
Satellite Service (FSS), shared with other services, e.g. the Fixed Service (FS) and the Mobile Service (MS):
- 5,850 GHz to 7,075 GHz (Earth-to-space);
- 3,400 GHz to 4,200 GHz (space-to-Earth);
- 4,500 GHz to 4,800 GHz (space-to-Earth);
• the VSAT uses linear or circular polarization;
• the VSAT operates through a geostationary satellite at least 2° away from any other geostationary satellite
operating in the same frequency band and covering the same area;
• the VSAT antenna diameter does not exceed 7,3 m, or equivalent effective area;
• the VSAT is either:
- a transmit-only VSAT: designed for transmission-only of radio-communications signals in the frequency
band (earth-to-space) specified in the present clause; or
- a transmit-and-receive VSAT: designed for transmission-and-reception of radio-communications signals
in the frequency bands specified in the present clause; or
- a receive-only VSAT: designed for reception-only of radio-communications signals in the frequency
band (space-to-Earth) specified in the present clause;
• the VSAT is designed for unattended operation;
• the VSAT 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 between users; the VSAT is controlled, and monitored for the transmit
functionality, by a Centralized Control and Monitoring Facility (CCMF). The VSAT has to implement Control
and Monitoring Functions with either Class A or Class B (structures of the radio states). The specifications
associated to the CCMF facility are outside the scope of the present document.
The present document applies to the VSAT with its ancillary equipment and its various terrestrial ports, and when
operated within the boundary limits of the operational environmental profile defined for the intended use of the VSAT
including all equipment as brought to the market.
The present document does not contain any requirement, recommendation or information about the installation of the
VSAT.
All parts of the indoor unit related to reception, processing and presentation of the received information except the
control channel are not within the scope of the present document. The syntax of the control channel messages is outside
the scope of the present document. The present document is intended to cover the provisions of Directive 2014/53/EU
(Radio Equipment Directive) [i.5] article 3.2.
NOTE: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.5] is given in annex A.
