| Abstract: | The first results of the International GLONASS Experiment 1998 (IGEX-98) campaign have provided significant material to illustrate
the mutual benefits of the GLONASS system and the realization of the International Terrestrial Reference System (ITRS). A
specific aspect, namely the relationship between the World Geodetic System 1984 (WGS 84) and the PZ-90 system using ITRS as
a primary standard, is investigated. A review of current works is carried out. A transformation strategy is proposed for the
three systems based on recent results from IGEX-98 and an independent set of transformation parameters derived by the Jet
Propulsion Laboratory from ITRF97 and PZ-90 coordinates for 16 global stations.
