oSIST prEN 302 340 V2.1.19:2026 is the Slovenian adoption of ETSI EN 302 340 for Satellite Earth Stations on board Vessels (ESVs) operating in the 11/12/14 GHz bands allocated to the Fixed Satellite Service (FSS). It specifies the technical characteristics, measurement methods, and conformance tests used to assess radio spectrum access for maritime ESV equipment and its control and monitoring functions.

What does oSIST prEN 302 340 V2.1.19:2026 specify?

oSIST prEN 302 340 V2.1.19:2026 specifies requirements and test methods for ESVs installed on vessels, including their above-deck and below-deck parts, ancillary equipment, and telecommunication ports. It is written for equipment that transmits in the 14.00 GHz to 14.50 GHz uplink band and receives in one or more 10.70 GHz to 12.75 GHz downlink bands, uses linear polarization, and operates through geostationary satellites.

The document is organized into scope, references, terms, technical requirements, environmental test conditions, and detailed test methods. It also includes annexes on the relation to Directive 2014/53/EU, mechanical stability methodology, measurement uncertainty, bibliography, and change history.

Annex	What it covers
Annex A	Relationship between the standard and the essential requirements of Directive 2014/53/EU
Annex B	Mechanical stability methodology for the above-deck unit
Annex C	Recommended maximum measurement uncertainty
Annex D	Bibliography
Annex E	Change history

What are the key requirements of oSIST prEN 302 340 V2.1.19:2026?

oSIST prEN 302 340 V2.1.19:2026 focuses on spectrum use, emissions control, antenna behavior, and remote supervision. In practice, it asks manufacturers and test labs to prove that the ESV transmits where and how it is allowed to, stops transmitting when required, and remains under network control.

Spectrum emissions and unwanted radiation

Clause 4.2.1 sets limits for off-axis spurious radiation in different radio states, and clause 4.2.2 covers on-axis spurious radiation. Clause 4.2.3 addresses maximum emissions toward the horizon. These clauses matter because the ESV must not create harmful interference in nearby systems, especially in maritime and satellite environments.

Clause 4.2.4 limits off-axis e.i.r.p. emission density within the band. The standard uses angle-dependent masks and takes account of pointing error, satellite spacing, and the operating relationship to the geostationary orbit. For the reader, this means the antenna pattern and pointing behavior are part of compliance, not just the transmitter output power.

Clause 4.2.5 covers carrier suppression. Clause 4.2.11 and 4.2.12 cover receiver blocking and adjacent signal selectivity. These receiver clauses matter because the ESV must stay functional in a crowded radio environment and resist strong unwanted signals without losing service.

Antenna pointing, stability, and alignment

Clause 4.2.6 covers antenna mechanical stability and antenna pointing. The standard expects the antenna to maintain pointing accuracy under defined operating conditions, because beam pointing directly affects both satellite link quality and interference risk.

Annex B gives the analytical or numerical methodology for mechanical stability. It uses wind and gust loading to check that the structure does not deform in ways that affect pointing, and it identifies the critical fixing points that must be assessed. In practice, this tells designers how to demonstrate that the mount and antenna structure can survive maritime loading while still remaining usable.

Cessation of emissions and network control

Clause 4.2.7 requires the ESV to cease emissions when the operating conditions demand it. It defines the needed information exchange between the ESV and the Network Control Facility (NCF), the conditions that trigger cessation, and the fault cases that must be treated as cessation conditions. It also requires a fast transition to the emissions-disabled state, which is important for protecting restricted zones and respecting network instructions.

Clause 4.2.9 sets out Control and Monitoring Functions (CMFs), including the state diagram, processor monitoring, transmit subsystem monitoring, power-on/reset behavior, Control Channel (CC) and Response Channel (RC), network control commands, and initial burst transmission. In practical terms, the ESV must not transmit unless it has the right control information, and it must react predictably to Transmission Enable command (TxE) and Transmission Disable command (TxD).

Identification and operational state behavior

Clause 4.2.8 requires identification of the ESV. The standard also defines ESV states and radio states in table 1, including non-valid, initial phase, transmission enabled, transmission disabled, carrier-on, carrier-off, and emissions disabled states. This is important because the test methods and control logic depend on the exact state of the equipment at each moment.

What terms does oSIST prEN 302 340 V2.1.19:2026 define?

• Above-deck unit - The part installed above the vessel deck, typically including the antenna subsystem, LNB, up-converter, power amplifier, and tracking or stabilization functions.
• Below-deck unit (BDU) - The part installed inside the vessel, together with its connection cables to the above-deck unit.
• Network Control Facility (NCF) - The system-level control entity that monitors and controls ESV operation within a network.
• Control Channel (CC) - The channel or channels used by the ESV to receive control information from the NCF.
• Response Channel (RC) - The channel used by the ESV to send monitoring information to the NCF.
• Nominated bandwidth - The transmit bandwidth nominated for the intended use of the ESV, centered on the transmit frequency and wide enough to cover the relevant transmitted spectrum.
• Spurious radiation - Any radiation outside the nominated bandwidth.
• Emissions disabled radio state - The state in which the ESV does not emit.

Who uses oSIST prEN 302 340 V2.1.19:2026?

oSIST prEN 302 340 V2.1.19:2026 is used by ESV manufacturers, antenna integrators, maritime satellite system designers, and test laboratories. It is also relevant to quality managers and conformity assessment teams who need to verify spectrum behavior, remote control behavior, and environmental robustness.

Network operators and NCF implementers use it to define control and monitoring behavior, including when the ESV is allowed to transmit and how it must respond to disable commands. Regulatory and compliance teams use it as a harmonised standard linked to Directive 2014/53/EU in Annex A.

What changed in oSIST prEN 302 340 V2.1.19:2026 from the previous edition?

Annex E records a sequence of editorial and review updates leading to this version. The latest listed update before this draft is a WG HARM review that updated references to OATS and the preferred test site.

Which standards are used with oSIST prEN 302 340 V2.1.19:2026?

The following referenced documents support application of the standard:

• CISPR 16-1 - Provides the radio disturbance and immunity measuring apparatus framework used for emission measurements.
• CISPR 16-1-5 - Provides antenna calibration sites and reference test sites for measurements from 5 MHz to 18 GHz.
• EN 60945 - Supplies maritime navigation and radiocommunication test requirements and limits used for below-2 GHz maritime emissions.
• ITU Radio Regulations - Provide the wider satellite and spectrum regulatory context used by the standard.
• ITU Radio Regulations Resolution 902 (Rev. WRC-23) - Sets provisions for ESVs in FSS networks in the 14-14.5 GHz uplink band.
• Directive 2014/53/EU - The radio equipment directive linked to presumption of conformity in Annex A.
• ETSI TR 102 215 - Gives guidance on measurement uncertainty above 1 GHz.
• ETSI TR 102 375 - Helps determine the part of the antenna pattern concerned by geostationary orbit protection.
• ETSI EG 203 336 - Gives guidance on selecting technical parameters for harmonised standards.
• ETSI TR 100 028-2 - Supports uncertainty estimates for mobile radio equipment measurements.
• ECC/DEC/(05)10 - Addresses free circulation and use of ESVs in CEPT countries.

What does the oSIST prEN 302 340 V2.1.19:2026 document contain?

The document contains state tables, emission limit tables, receiver performance criteria, and many test-set-up figures for conducted and radiated measurements. It also provides detailed procedures for measuring spurious radiation, antenna gain patterns, antenna pointing, emissions cessation, control channel behavior, and blocking performance.

Annex B adds a structured load-analysis method for mechanical stability, while Annex C gives recommended uncertainty values that apply across the test cases. Annex A maps the technical clauses to the essential requirements of Directive 2014/53/EU, so readers can see which parts support spectrum-related conformity claims.

1 Scope
The present document specifies technical characteristics and methods of measurements for Earth Stations located on
board Vessels (ESVs) which have the following characteristics:
• The ESV is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on board (usually referred to as the terrestrial interface).
• The ESV transmits in the frequency range from 14,00 GHz to 14,50 GHz in the Fixed Satellite Services
(FSS) (earth-to-space).
• The ESV receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in the bands
allocated to the Fixed Satellite Services (FSS) (space-to-earth), depending on the ITU Region where the
ESV is located.
• The ESV uses linear polarization.
• The ESV operates through a geostationary satellite at least 2° to 3° away from any other geostationary
satellite operating in the same frequency band and covering the same area.
NOTE 1: The satellite spacing is mainly equal to 3° in ITU Regions 1 and 3 and 2° in ITU Region 2.
• The ESV transmits at elevations greater or equal to the minimum elevation angle defined for its intended
use.
• The ESV antenna diameter is not smaller than 0,6 m.
NOTE 2: Operation within 125 km of non-CEPT countries is subject to specific agreement with concerned
administrations as stated in ITU-R Resolution 902 (Rev. WRC-23). Decision ECC(05)10 [i.9] applies
for CEPT countries.
• The ESV is designed for transmission and reception of radio-communications signals in accordance with

1 Scope
The present document specifies technical characteristics and methods of measurements for Earth Stations located on
board Vessels (ESVs) which have the following characteristics:
• The ESV is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on board (usually referred to as the terrestrial interface).
• The ESV transmits in the frequency range from 14,00 GHz to 14,50 GHz in the Fixed Satellite Services
(FSS) (earth-to-space).
• The ESV receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in the bands
allocated to the Fixed Satellite Services (FSS) (space-to-earth), depending on the ITU Region where the
ESV is located.
• The ESV uses linear polarization.
• The ESV operates through a geostationary satellite at least 2° to 3° away from any other geostationary
satellite operating in the same frequency band and covering the same area.
NOTE 1: The satellite spacing is mainly equal to 3° in ITU Regions 1 and 3 and 2° in ITU Region 2.
• The ESV transmits at elevations greater or equal to the minimum elevation angle defined for its intended
use.
• The ESV antenna diameter is not smaller than 0,6 m.
NOTE 2: Operation within 125 km of non-CEPT countries is subject to specific agreement with concerned
administrations as stated in ITU-R Resolution 902 (Rev. WRC-23). Decision ECC(05)10 [i.9] applies
for CEPT countries.
• The ESV is designed for transmission and reception of radio-communications signals in accordance with
any of the frequency bands specified above.
• The ESV is usually designed for unattended operation.
• The ESV 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 ESV is controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope
of the present document.
The present document applies to the ESV with its ancillary equipment and its various telecommunication ports, and
when operated within the boundary limits of the operational environmental profile defined for its intended use
including all equipment as brought to the market.
The present document incorporates the technical limitations listed in annex 2 of ITU Radio Regulations
Resolution 902 (Rev. WRC-23) [9].
NOTE 3: The relationship between the present document and essential requirements of article 3.2 of
Directive 2014/53/EU [i.8] (RE Directive) is given in annex A.
