<p>Starting from 1999 a new geodetic reference system MOLDREF99 based on the ITRF97 and ETRS89 was established in Republic of Moldova. The realization of MOLDREF99 is the national GNSS Network with density about 1 point per 15 sq. km.

In 2011 national positioning service MOLDPOS was put on function with 10 permanent GNSS stations to provide real time positioning services. In order to improve the accuracy of digital terrain models along the Prut River the local quasigeoid model is necessary to develop taking in consideration GNSS/Levelling differences and gravity data.
