[Difx-users] ITRF realisations {External}

[Phillips, Chris (S&A, Marsfield)]

Hi all,

I have just learned that ITRF (which we use as the XYZ coordinate system of our telescopes) has multiple realisations (ITRF2000, ITRF2014 etc).

There was approx a 9cm change between around ITRF2005, which is huge.

The “Frame” detail in Sched is light on details and vex2difx make no mention of frame.

Does anyone know what ITRF frame Sched expects?

Thanks
Chris
