Overview
SIST EN 302 194-1 V2.1.1:2026 is a harmonised European standard focusing on magnetron-based navigation radars for inland waterways, developed by SIST in alignment with ETSI. Its primary purpose is to specify the technical characteristics and measurement methods necessary for ensuring effective access to the radio spectrum for navigation radars operating in the 9 300 MHz to 9 500 MHz frequency range. The standard aims to support regulatory compliance, facilitate market access, and ensure the reliable and safe operation of radar systems used for navigation and collision avoidance on inland waterways.
Key features of this standard include requirements for transmitter peak power, emission limits, receiver performance, and measurement methods that help manufacturers design, test, and certify their magnetron radar equipment in accordance with essential regulatory directives such as Directive 2014/53/EU (Radio Equipment Directive).
Key Topics
Applications
This standard is highly relevant for:
- Manufacturers of radar systems for inland vessels, enabling them to design and test equipment that meets harmonised EU requirements and supports safe navigation.
- Regulators and Notified Bodies, who rely on the standard to assess compliance for market approval within the EU and EFTA member states.
- Vessel Operators, ensuring that installed radars provide reliable performance, minimise interference, and foster navigational safety along rivers, canals, and other inland waterways.
Typical application scenarios include new radar installations on passenger ships, cargo vessels, and workboats operating in regulated inland waterway regions, as well as maintenance or upgrade projects where equipment conformity is essential.
Related Standards
For a broader regulatory context, readers should consider:
- ETSI EN 303 676: Covers operational, functional, and technical requirements for inland waterway navigation radars.
- IEC 60945: International standard on electromagnetic compatibility and environmental testing of maritime equipment.
- ITU-R Recommendations: Including ITU-R M.1177 for emissions measurement and ITU-R SM.1541 for emission domain definitions.
- Directive 2014/53/EU: The Radio Equipment Directive.
- SIST EN 302 194-2: Addresses similar requirements for solid-state radars.
By following SIST EN 302 194-1 V2.1.1:2026, organisations benefit from a robust framework for navigation radar compliance, ensuring efficient radio spectrum use and safe, interference-free operation on European inland waterways.
