Description

The global solutions are the first type of IDS geodetic products, defined within the scientific community working with IERS, IVS, IGS, ILRS and/or IDS. The purpose of this product is to serve as input for global combinations. They include two types of estimated parameters and the corresponding variance-covariance information, as follows:

  • global astro-geodetic parameters that describe station positions and motions, Earth orientation,motion of the station network with respect to the Earth's center of mass, satellite motion (caseof satellite geodesy) and radio source directions (case of VLBI);
  • parameters for local models, such as those describing the effect of the troposphere on thesignal transmission. These solutions are provided in the SINEX (Software INdependent EXchange)
