- BIPM, Sèvres France
Overview
This school, sponsored by the BIPM and the IEEE UFFC Society, will cover key topics through tutorial lectures emphasizing Q&A sessions, along with hands-on training using analysis tools developed in the CCTF CBKT program. Participants will gain practical experience in GNSS receiver operation and calibration, clock data analysis, time scale generation, and time transfer techniques relevant to UTC(k) operations and contributions to UTC.
The objective of this workshop is to support institutes in enhancing their national standard time realization and strengthening their contributions to Coordinated Universal Time (UTC) through participation in BIPM Circular T / Key Comparison CCTF-K001.UTC. The training will provide both foundational and in-depth technical knowledge necessary for UTC participation.
The school is planned as a three-day program, designed for skill development and knowledge sharing. The content is structured to help newcomers—including engineers, scientists, and technical staff at national time laboratories—gain the expertise required to maintain their national time scale. This includes analysing clock data, creating an averaged ensemble time scale, steering the time scale, applying GNSS time transfer techniques, and submitting data to the BIPM.
BIPM products that provide access to UTC and enable the monitoring of transmitted data quality will also be presented. Additionally, participants are invited to share their technical solutions for the realization and automation of UTC(k) when these may be of interest to others, particularly when automation tools can be shared.

Sample Data
The school will include hands-on sessions where students can use their own lab data, or sample data, to follow in guided demonstrations of web-based applications. Sample for these sessions can be found here:
