Overview
SIST EN 300 338:1999 specifies the technical characteristics and measurement methods for maritime equipment used for the generation, transmission, and reception of Digital Selective Calling (DSC) in the MF, MF/HF, and VHF mobile services. This Slovenian standard, identical to EN 300 338 V1.2.1, ensures electromagnetic compatibility (EMC) and efficient use of the radio spectrum for maritime communication systems, particularly those supporting the Global Maritime Distress and Safety System (GMDSS).
A key scope of this document is the technical correction of the test method related to residual frequency modulation in MF/HF DSC encoders, ensuring accurate and reliable performance assessment.
Keywords: maritime communication, digital selective calling, GMDSS, electromagnetic compatibility, test methods, MF/HF radio, VHF radio
Key Topics
Electromagnetic Compatibility (EMC):
Ensures equipment meets all relevant emission and immunity requirements, minimizing interference and supporting reliable maritime communication.Technical Characteristics:
Covers the design, frequency accuracy, output power, signal quality, unwanted emission limits, and modulation characteristics for both transmitters and receivers.Measurement Methods:
Standardizes procedures for testing and verifying compliance, including:- Frequency error measurement
- Residual and unwanted modulation
- Out-of-band emissions
- Bit stream speed and error rates
- Environmental and operational condition tests
DSC Call Handling:
Defines requirements for coding, decoding, and handling of DSC calls across distress, urgency, safety, and routine communication.Safety and Reliability:
Addresses protection measures, alarm circuits, remote operation, accessibility, and calibration to ensure the safety of maritime operations.
Applications
SIST EN 300 338:1999 is pivotal for manufacturers, testing labs, and maritime organizations involved in:
Marine radio equipment development:
Ensures that new MF, MF/HF, and VHF DSC devices comply with international standards for interoperability and safety.Type approval and certification:
Provides a harmonized basis for assessing radio equipment, required for national and international type approval procedures.Vessel communication systems:
Used by shipping companies and maritime authorities to implement compliant DSC solutions within the GMDSS framework for vessel-to-vessel and vessel-to-shore communication.Testing and quality assurance:
Testing labs and quality assurance teams utilize these methods to verify product compliance and environmental robustness.Distress, safety, and routine maritime communication:
Supports effective and standardized handling of emergency calls and routine maritime traffic, increasing safety at sea.
