The recent research developments within the framework of the project "Atmospheric impact on GPS observations in Antarctica" are presented in the paper. The effects of both ionospheric and tropospheric disturbances on GPS solutions are discussed. The GPS data, usually those provided by permanent GPS station arrays, are commonly used to investigate the structure and dynamic of ionosphere. First results of the project address the influence of the ionosphere over the Arctic and Antarctic regions on the repeatability of co-ordinates of vectors of different length during the quiet and disturbed ionosphere (ionospheric storms).
