SIST EN 301 681:2001
(Main)Satellite Earth Stations and Systems (SES); Harmonized EN for Mobile Earth Stations (MESs) of Geostationary mobile satellite systems, including handheld earth stations, for Satellite Personal Communications Networks (S-PCN) in the 1,5/1,6 GHz bands under the Mobile Satellite Service (MSS) covering essential requirements under Article 3.2 of the R&TTE Directive
General Information
- Abstract
S-PCN terminals working with Geostationnary Satellites This EN is intended to define the minimum performance requirements and technical characteristics of Mobile Earth Stations (MES) with both transmit and receive capabilities for operation in a Geostationnary Satellite Personal Communication Network (S-PCN). An S-PCN MES may be handheld, portable, vehicle-mounted, host connected, semi-fixed or fixed equipment, or may be an element in a multi-mode terminal; it may consist of a number of modules with associated connections and user interface, or may be a self contained single unit. This EN will specify the requirements of the S-PCN MES element of the terminal operating in one or more of the MSS frequency bands dedicated to geostationnary S-PCNs in the 1,5/1,6 GHz band. The requirements to be defined may cover following two major categories: unwanted emission limits: to protect other radio services from harmful interference generated by the MES in normal use; MES Control and Monitoring Functions (CMF): to protect other radio services from unwanted transmissions from the MES. The CMF in each MES is capable of answering to commands from the Network Control Facilities (NCF) for the operating S-PCN.

Overview
SIST EN 301 681:2001 specifies the essential requirements and technical characteristics for Mobile Earth Stations (MES) operating in the 1.5/1.6 GHz bands of geostationary Satellite Personal Communications Networks (S-PCN) under the Mobile Satellite Service (MSS). Published by the Slovenian Institute for Standardization (SIST), this harmonized standard ensures compliance with Article 3.2 of the R&TTE Directive, focusing on spectrum efficiency and interference prevention for mobile satellite terminals-including handheld, vehicle-mounted, portable, semi-fixed, and fixed configurations.
This standard is critical for manufacturers, integrators, and regulatory bodies engaged in the design, testing, or approval of satellite earth stations and mobile communications equipment operating via geostationary satellite systems.
Key Topics
Scope and Applicability
- Covers S-PCN MES for geostationary systems in the MSS frequency bands: 1525-1559 MHz (receive) and 1626.5-1660.5 MHz (transmit).
- Applicable to various MES types: handheld, host-connected, portable, vehicle-mounted, semi-fixed, or elements within multimode terminals.
Essential Performance Requirements
- MES must efficiently use the allocated spectrum and avoid causing harmful interference to other radio services.
- Defines environmental operating conditions for MES, including parameters for temperature, voltage, and vibration.
Unwanted Emissions and Control
- Sets strict limits on unwanted emissions outside the allocated band to protect adjacent radio services.
- Imposes requirements for MES Control and Monitoring Functions (CMF) to ensure the MES can respond to commands from the network’s control facility, especially to disable/enable transmission.
Compliance and Testing
- Outlines conformance assessment procedures, including laboratory testing under specified environmental and operational conditions.
- Detailed test suites address measurement of unwanted emissions, performance under voltage extremes, and operation during vibration.
Applications
SIST EN 301 681:2001 is used in the following real-world scenarios:
Development and Certification of Satellite Terminals
- Ensures new MES designs meet European Union legal requirements for operation within S-PCN geostationary satellite networks.
- Used during equipment testing and validation to demonstrate compliance with emission limits and control protocols.
Regulatory Approval Processes
- Provides a harmonized basis for regulatory bodies to assess and approve mobile earth stations for market entry.
- Ensures coexistence and spectrum sharing among multiple satellite and terrestrial systems in the 1.5/1.6 GHz bands.
System Integration and Multi-Mode Devices
- Valuable for integrators building multi-mode terminals (supporting both terrestrial and satellite links) requiring clear demarcation of MES performance responsibilities.
Operational Network Management
- Supports network operators in managing devices via network-initiated control messages, ensuring remote disablement or frequency adjustments to prevent interference.
Related Standards
For broader context and interoperability, consider these related standards and directives:
- EN 301 682: Specifies requirements for Network Control Facilities (NCF) in S-PCNs.
- R&TTE Directive (1999/5/EC): The overarching regulatory framework for radio equipment and telecommunications terminal equipment in the EU.
- EN 301 489 series: Addresses Electromagnetic Compatibility (EMC) requirements for radio equipment.
- EN 60950 (now EN 62368): Pertains to electrical safety for ICT and telecom equipment.
- ITU Recommendations: Such as ITU-T O.153, for data transmission apparatus characteristics.
Implementing SIST EN 301 681:2001 guarantees that mobile satellite terminals not only adhere to established performance criteria but also support efficient, interference-free usage of spectrum-vital for the reliable functioning of modern satellite personal communications services.
