THE INFLUENCE OF OCEAN TIDES TO DETERMINE THE EARTH'S ORIENTATION PARAMETERS

Abstract

The paper deals with the themes of the Earth's orientation and rotation. The parameters of the Earth's
orientation can be determined by several methods. The emphasis in this paper is the influence of ocean
tides to determine the parameters of the Earth's orientation with one of the space-geodetic techniques,
called Very long baseline interferometry (VLBI). After determining the parameters, the results obtained
using the VLBI were compared between reference system VieVS and Vrf2008, as well as influence of
ocean tides and without its impact.
When processing the data, the obtained results were compared using different reference systems and
various that influence their changes were analyzed. The used data belong to different series of programs
that are continuously observed. The results are the product of software VieVS with data from a
continuing series CONT14.
