SIST EN 301 459:2001 is a SIST adoption of ETSI EN 301 459 Version 1.2.1 for Satellite Earth Stations and Systems (SES). It specifies essential requirements under Article 3.2 of the Radio and Telecommunications Terminal Equipment (R&TTE) Directive for Satellite Interactive Terminals (SIT) and Satellite User Terminals (SUT) that transmit toward geostationary satellites in the 29,5 GHz to 30,0 GHz band.
What does SIST EN 301 459:2001 specify?
SIST EN 301 459:2001 specifies the spectrum-related requirements for two-way satellite terminals operating as part of a bidirectional satellite network. The focus is on transmit performance, unwanted emissions, antenna pointing, and control functions that prevent harmful interference.
The document applies to Satellite Terminal (ST) equipment used with Satellite Interactive Terminals (SIT) and Satellite User Terminals (SUT), including the outdoor and indoor units and the cables between them. It is written for equipment operated within the manufacturer-declared environmental profile and installed as required by the manufacturer.
| Annex | What it covers |
|---|---|
| Annex A | The EN Requirements Table (EN-RT), a summary of the requirements and their status |
| Annex B | Pointing stability methodology based on numerical analysis |
The main structure is:
- Clause 1 - Scope
- Clause 2 - References
- Clause 3 - Definitions, symbols and abbreviations
- Clause 4 - Technical requirement specifications
- Clause 5 - Testing for compliance with technical requirements
- Clause 6 - Test method
The document also states that installation requirements and the syntax of control channel messages are not covered.
What are the key requirements of SIST EN 301 459:2001?
SIST EN 301 459:2001 combines emission limits with control logic so the terminal only transmits when it should. In practice, manufacturers need to declare operating parameters, implement monitoring, and show the terminal stays inside the emission masks under the stated test conditions.
Spectrum and emissions
Clause 4 sets limits for off-axis spurious radiation, on-axis spurious radiation, off-axis EIRP emission density within the band, and carrier suppression. These requirements matter because they protect other satellite and terrestrial services from interference.
- Off-axis spurious radiation is limited in the specified frequency ranges, with different limits for the "Transmission disabled" state and for the "Carrier-on" and "Carrier-off" states.
- On-axis spurious radiation is limited separately in the 29,5 GHz to 30,0 GHz band for the "Carrier-on" state and for the "Carrier-off" and "Transmission disabled" states.
- Off-axis EIRP emission density within the band is checked against a mask built from transmit power density and antenna patterns.
- The rules take account of multicarrier operation and declared values such as EIRPmax, EIRPnom, nominated bandwidth, and the number of simultaneous transmitters.
Antenna pointing and alignment
Clause 4 also requires antenna pointing accuracy and alignment capability. The terminal has to remain mechanically stable under wind loading, and the antenna assembly must support the declared pointing accuracy and polarization alignment.
This matters because small pointing errors can move energy into adjacent satellite directions. The document therefore links antenna adjustment, geostationary orbit alignment, and the measured radiation pattern.
Control and Monitoring Functions (CMF)
Clause 4.2.7 defines the minimum CMF behavior. The ST uses the states "Non-valid", "Initial phase", "Transmission disabled", and "Transmission enabled" to control when it may transmit.
The ST must:
- stop transmitting if processor faults are detected
- stop transmitting if the transmit frequency-generation subsystem fails
- remain non-transmitting during power-on and reset
- enter "Non-valid" if the Control Channel (CC) is not correctly received
- accept and act on Transmission Enable and Transmission Disable commands from the network
- limit initial burst transmission in the "Initial phase" state
For a buyer or integrator, these are the practical safeguards that show the terminal will shut down or restrict transmission when network control is lost.
What terms does SIST EN 301 459:2001 define?
- Satellite Terminal (ST) - The generic name used for either a Satellite Interactive Terminal (SIT) or a Satellite User Terminal (SUT).
- Control Channel (CC) - The channel or channels through which the ST receives control information from the Network Control Facility (NCF).
- Network Control Facility (NCF) - The network element responsible for monitoring and controlling ST transmit functions.
- Carrier-on state - The state in which the ST is authorized to transmit and is actually transmitting.
- Carrier-off state - The state in which the ST is authorized to transmit but is not transmitting any signal.
- Transmission disabled state - The state in which the ST is not authorized by the NCF to transmit.
- Environmental profile - The declared range of environmental conditions under which the equipment must comply.
- EIRPmax / EIRPnom - Manufacturer-declared maximum and nominal Equivalent Isotropically Radiated Power values used for compliance checks.
Who uses SIST EN 301 459:2001?
SIST EN 301 459:2001 is used by terminal manufacturers, satellite network operators, test laboratories, and conformity assessment teams. It is also useful for quality managers and buyers who need to confirm that a SIT or SUT design is built to meet the essential spectrum requirements for operation in the 29,5 GHz to 30,0 GHz band.
In practice, users apply it when designing the RF chain, setting antenna tolerances, writing test plans, and documenting compliance evidence for a bidirectional satellite network.
Which standards are used with SIST EN 301 459:2001?
- Directive 98/34/EC - Sets the procedure for information in the field of technical standards and regulations.
- Directive 1999/5/EC - The R&TTE Directive that provides the legal basis for the essential requirements addressed by this EN.
- CISPR No 16-1 - Gives the measuring apparatus and methods used for radiated disturbance measurements.
- ETSI EN 301 358 - Companion SUT standard for geostationary satellite user terminals in the 19,7 GHz to 20,2 GHz and 29,5 GHz to 30 GHz bands.
- ETSI EN 301 359 - Companion SIT standard for geostationary satellite interactive terminals in the 11 GHz to 12 GHz and 29,5 GHz to 30,0 GHz bands.
- ETSI EN 300 421 - Provides the DVB framing, channel coding, and modulation reference mentioned for typical SIT reception.
What does the SIST EN 301 459:2001 document contain?
The document contains detailed limit tables, test arrangements, and measurement procedures for spurious emissions, antenna gain, radiation patterns, carrier suppression, and control-channel behavior. It includes figures for test setups, including radiated and conducted measurements, and a state transition diagram for CMF behavior.
Clause 6 gives the practical test methods, including receiver settings, antenna orientations, substitution measurements, and the way to calculate off-axis EIRP from measured power density and antenna gain. Annex A turns the requirements into an EN Requirements Table, and Annex B gives a numerical methodology for pointing stability analysis.
