Аннотация:We recall a known inertial effect in satellite motion caused by the indirect acceleration of the center of integration (the central planet) due to the oblateness of the planet and an attracting third-body. As estimated, the effect leads to perturbations in satellite motion to be well detectable by the modern tools of measuring the satellite orbital parameters.
However, the effect is not described by the current IERS Conventions (2003); we suggest to include it to the future IERS Conventions (2010).
