IVS Products "Baseline lengths":

Baseline lengths between geodetic VLBI observatories are regularly computed from VLBI data analysis solutions of six IVS Analysis Centers:

CGSCentro di Geodesia Spaziale (CGS), Matera, ItalyCALC/SOLVE 3410

OPA Observatoire de Paris, Paris, France  CALC/SOLVE 4527
USNOUnited States Naval Observatory, Washington D.C., USACALC/SOLVE 3780

Solutions for this purpose are being submitted routinely to the IVS Analysis Coordinator's office in SINEX files.
From this input data numerical baseline length results and statistics as well as VLBI baseline length evolution graphs are produced.
In addition, a combined set of baseline length results is computed and is displayed graphically together with the contributing series.
Baseline results are updated in irregular intervals.

Results can be displayed and retrieved through the interactive baseline selection scheme below.
