Major news for VLBI and geodesy!

Major news for VLBI and geodesy!

Nicholas Brown@nich0lasBr0wn

Very early this morning (Australia time) the United Nations Global Geodetic Centre of Excellence was announced. The importance of this moment is hard to put into words.

Geodesy is not well known by most people, but it benefits us all.

Article by @josh_sokol: "For the past few decades, astronomers have based their celestial grid on radio observations of several thousand quasars...the bedrock of the reference frame...Without them, GPS devices would lose their accuracy": this is where #VLBI & the IVS are crucial!

Josh Sokol@josh_sokol

For millennia our deepest scientific traditions dreamed of mapping the sky and the bucking Earth beneath it. Next week, that quest will become easier than ever.

I'll tell you how in a THREAD based on my recent piece @NewsfromScience.
