[IGSMAIL-6513] New IGS Analysis Center Coordinator

[Urs Hugentobler]

Dear Colleagues,

The term of Jim Ray as Analysis Center Coordinator comes to an end by 
the end of this year and - as announced in the previous IGS Mail by Jim 
-Jake Griffiths will take over the ACC responsibility.

For the last four years Jim did an exceptional job, devoting his deep 
understanding of all aspects from signal acquisition to data analysis 
and product generation and validation to the ACC task. Our all 
impression was that he checked each single line in each combination 
protocol, and we all remember his immediate reaction if any quality 
metrics showed an anomalous behavior. He continuously analyzed the IGS 
products for inconsistencies and time series of transformation 
parameters, orbit overlaps, Earth rotation parameters, station 
coordinates, etc. for anomalous frequencies, indications for 
overconstraining, impact of inconsistencies. And he never ceased to push 
the Analysis Centers to further improve the quality and consistency of 
their products. With this unwavering effort he enabled the IGS to 
provide the highest standard products to users without interruption.

On behalf of the IGS I want to sincerely thank you, Jim, for your 
outstanding work and wish you will still look at the IGS products from 
different angles and tell us your comments and advises. I also want to 
thank Jake Griffiths for his excellent support as well as NGS for the 
significant involvement for one of the most important functions in the IGS.

During the course of this year the IGS received an excellent proposal 
from NGS to continue to support the ACC function for the next term of 
four years, a proposal that was unanimously approved by the Governing 
Board. I am very glad that Jake Griffith takes over as our Analysis 
Center Coordinator and successor of Jim Ray with the beginning of 2012 
with the support of Kevin Choi, focusing on the core ACC tasks. I wish 
both much success with their important role. I sincerely thank NGS for 
the continued commitment with significant resources for the IGS that 
demonstrates the importance that NGS attributes to the ACC task. And I 
look forward to a continued fruitful collaboration and close interaction 
with our new ACC and to a further advance of the quality of the IGS 
products!

With best wishes for the New Year
Urs Hugentobler
Chairman
IGS Governing Board
