EN 61108-2:1998

Overview

EN 61108-2:1998 is a key European standard that defines performance standards, testing methods, and required test results for shipborne receiver equipment using the Russian Global Navigation Satellite System (GLONASS). This standard is part of the broader maritime navigation and radiocommunication equipment and systems guidelines under the Global Navigation Satellite Systems (GNSS) framework. It aligns with the International Maritime Organization (IMO) Resolution MSC.53(66), ensuring that GLONASS-based maritime navigational receivers meet stringent accuracy, reliability, and operational requirements.

This standard supports safe and efficient maritime operations by specifying minimum performance criteria that facilitate precise positioning at sea using GLONASS signals. Published by the CLC (European Committee for Electrotechnical Standardization), it is crucial for manufacturers, testing laboratories, and maritime authorities engaged in the development, certification, and regulation of GNSS receiver equipment.

Key Topics

• Performance Standards for GLONASS Receivers
  EN 61108-2 sets out minimum technical requirements that shipborne GLONASS receivers must fulfill. These include parameters related to positioning accuracy, signal tracking capability, and operational reliability under various maritime conditions.

• Testing Methods
  The standard provides detailed procedures to test GLONASS receiver equipment, ensuring consistent evaluation. Tests cover signal acquisition, tracking performance, accuracy validation, environmental resilience, and error measurement.

• Required Test Results
  Clear pass/fail criteria and performance thresholds are defined for manufacturers and testing bodies. This ensures equipment compliance in terms of positional accuracy, availability, and integrity consistent with IMO performance requirements.

• IMO Alignment
  The standard is developed based on IMO Resolution MSC.53(66), cementing its role as a mandatory reference for maritime navigation safety involving GLONASS receivers.

Applications

• Maritime Navigation Safety
  Ensuring vessel navigational equipment using GLONASS meets international standards for accurate position fixing, reducing risks of grounding, collisions, and navigational errors.

• Receiver Manufacturing and Certification
  Manufacturers of GLONASS shipborne navigational receivers utilize EN 61108-2 to design compliant products. Certification bodies use this standard as a benchmark during product approval processes.

• Port and Coastal Infrastructure
  Authorities implementing navigation aids and harbor operations rely on GLONASS-based systems meeting these standards to support vessel traffic management and search and rescue operations.

• Maritime Electronics Testing
  Testing laboratories adopt the specified methods and pass criteria to validate performance and reliability of GNSS receivers before they enter the market or are deployed onboard.
