Products from five analysis centers of the International VLBI Service for Geodesy and Astrometry (IVS) were used as the input data, and Bernese 5.0, which is the global navigation satellite system (GNSS) data processing software, was used. In this study, the representative combination solution of very long baseline interferometry (VLBI), which is one of the space geodetic techniques, was produced, and the variations in the position coordinate of each station during 7 years were analyzed. To achieve this, the representative combination solution of each space geodetic technique has to be produced, and then those solutions need to be combined. Space geodetic techniques can be used to obtain precise shape and rotation information of the Earth.
