NASA GSFC global VLBI quarterly solution

NASA Goddard Space Flight Center provides solutions using all publicly accessible Very Long Baseline Interferometry (VLBI) data accumulated since [an error occurred while processing this directive] on a quarterly basis. The data used in these solutions are available from the NASA Crustal Dynamics Data Information System (CDDIS).

There are three types of solutions:

Geodetic global solutions present estimates of stations positions, station velocities, harmonic variations in site positions, parameters of non-linear station motions, positions of extragalactic radio sources, and the estimates of an expansion of the Earth orientation parameters into harmonic and B-spline bases from processing all publicly accessible VLBI group delays derived from processing all available geodetic experiments.
The lasest quarterly global geodetic solution: gsf_2024d

Geodetic baseline solutions that present estimates of the baseline vector from from processing all publicly accessible VLBI group delays derived from processing all available geodetic experiments.
The lasest quarterly baseline solution: bas_2024d

Astrometric solutions that present positions of compact radio sources and estimates of other parameters using all available VLBI observations at 8.6 GHz and 2.2 GHz, as well at 5 and 22 GHz from dedicated absolute astrometry programs and routine geodetic experiments.
The lasest quarterly baseline solution: rfc_2024d
