33 national metrology technical specifications were released in fields such as positioning and navigation, new energy, and ocean observation.

News from this site on July 2. This site learned from the official website of the State Administration for Market Regulation that the State Administration for Market Regulation has recently issued a batch of important National Metrology Technical Specifications, involving positioning and navigation, new energy, and ocean observation and many other fields.

This is the first batch of national metrology technical specifications released since the newly revised "National Metrology Technical Specifications Management Measures" were officially implemented on May 1, 2024.

In the field of positioning and navigation, the "Tiantong/Beidou Integrated High-Precision Navigation and Positioning Terminal Calibration Specifications", "Satellite Navigation-Based Land Orientation System Calibration Specifications", "Marine Gyro Compass Calibration Specifications" and other regulations stipulate the measurement of related measurement equipment Characteristic requirements, calibration items and calibration methods provide support for high-precision positioning in aerospace, land and ocean positioning and navigation systems, and are of great significance to ensuring the accuracy and reliability of measurement performance of measurement equipment in emergency rescue, geological disaster monitoring, ocean navigation and other fields.

In the field of

new energy, "Perovskite Solar Cell Calibration Specifications: Optoelectronic Performance Parameters" provides a unified, reasonable and achievable technical basis for the performance evaluation of perovskite solar cells.

In the field of

ocean observation, the "Ocean Data Buoy Sensor Calibration Specifications" will guide all maritime-related departments and units across the country to unify technical parameters, improve data comparability, provide technical support for the inclusion of data into the national global ocean stereoscopic observation network, and also provide technical support for the inclusion of data into the national global ocean stereoscopic observation network. Metrology technology institutions provide technical basis for sensor calibration.
