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



11/12

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.)
