Regional quasi-geoid determination in the area of Poland
Krynski, Jan & Adam Lyszkowicz
The paper presents a short summary and more detail description of preliminary results of research on precise geoid (quasigeoid) model in Poland conducted in 2002-2005. After the introduction where general outline of the work is presented, in the next sections the procedures of quasigeoid determination using gravity, astro-geodetic, GPS/levelling data separately as well as in combined solution are described. The developed quasigeoid models were intercompared. They were also compared with quasigeoid heights determined along the high precision, dense, 900 km long GPS/levelling traverse established for the project. The goodness of the fit of the obtained combined quasigeoid model, gravimetric quasigeoid model and astro-geodetic geoid model to the control traverse, measured with a standard deviation, equals to 1.8 cm, 2.1 cm, and 7 cm, respectively.
