Starting from 1999 a new reference system MOLDREF99 based on the ITRF97 and ETRS89 was established in Moldova. The realization of MOLDREF99 is the national GPS Network with density about 1 point per 15 sq. km. However, this density is insufficient for many geodetic applications. In order to provide real time positioning services the decision to pass from GPS “passive” Network to GNSS “active” Network in 2010 was adopted by Land Relation and Cadastre Agency. To provide real time position and navigation service on the territory of Moldova a new project of GNSS Permanent Network and MOLDPOS service was supported by Norwegian Government. To generate and distribute height anomalies for real time normal height determination from GNSS measurements a 3-4 cm accuracy Height Reference Surface based on precise GNSS/leveling was calculated by Technical University of Moldova in cooperation with Karlsruhe University of Applied Science. For future improvement of Height Reference Surface for territory of Republic of Moldova, a gravity quasigeoid model based on new gravity and vertical deflections measurements will be created. |
