Abstract
The Earth Orientation Parameters (EOP) uncertainty influence on the gravitational acceleration calculating during the LAGEOS-1 spacecraft orbit prediction is a matter of the article. This influence is compared with the error due to geopotential model variability. The EGM-96 and EGM-2008 geopotential models are considered, with and without taking account of the actual displacement of the Earth’s pole and its rotation irregularity according to final С04 bulletins of the International Earth Rotation and Reference Systems Service (IERS).
