Paris is home to the Bureau International des Poids et Mesures (BIPM), the intergovernmental organization that calculates the international reference time scale, Coordinated Universal Time (UTC), by collecting and comparing data from the world’s most accurate clocks. Since clocks and timing are critical components of space geodesy, a representative from BIPM – currently the Director of the BIPM Time Department, Felicitas Arias – sits on the IGS Governing Board. Dr. Arias has served the IGS community in this role since 2005.
IGS Clock Products and the associated Clock Products Working Group, established in 2003 after considerable joint work between the IGS and BIPM, now form a critical component of IGS Rapid and Final clock combinations.
The upcoming IGS 2017 Workshop in Paris will feature a session devoted to timing issues, co-convened by Associate Member Gérard Petit of BIPM, and IGS Clock Products Coordinator Michael Coleman of the United States Naval Research Laboratory. Presentations will include topics such as: links between the IGS and the time laboratories participating to UTC; IGS clock products and their assessment; use of IGS clock products for time and frequency transfer; calibration of geodetic time receivers; GNSS clock performance and development; and assessment of GNSS system time offsets and the interoperability of GNSS systems. There will also be a meeting of the Clock Products Working Group.
The IGS 2017 Workshop will take place 3-7 July at the University of Paris Diderot. For registration and more information about the upcoming IGS Workshop, please visit the 2017 Workshop Website. Regular updates are also posted on IGS Twitter and Facebook pages.
