Integration with EPN
IGEO
Starting from August 2007 the
Agency of Land Relations and
Cadastre in collaboration with BKG
installed and jointly operate aGNSS permanent tracking station
IGEO (Chisinau) integrated into
EPN and will be integrated in
MOLDPOS

Densification with the ~ 70 km spacing requires that at least 13permanent operating GNSS stations to be installed in order to
provide the differential GNSS for navigation and real time
kinematics for surveying
The Geodetic Data Base to be created forMOLDPOS service to
generate and distribute differential corrections, transformationparameters and height anomalies from the national quasigeoid
model
MOLDPOS will be used by a large spectrum of users (geodeticworks, cadastral surveying, GIS applications, mapping andboundary marking, etc.)
MOLDPOS will be the basis of support of scientific applications(landslide and floods monitoring, environmental research,
geohazard prediction, meteorology, etc.)
