Abstract

The content of the article focuses on studying methods for assessing the accuracy of coordinates measured by the Vietnamese National Satellite Positioning Station Network System (VNGEONE). The results of experimental measurements and the accuracy assessment of coordinates measured by the VNGEONE system in Vietnam at administrative boundary markers in the Dĩ An city area, Bình Dương province, and at cadastral grid markers in Bến Lức district, Long An province, confirm that: the GNSS- CORS VNGEONET technology (with Network RTK technology solution service) of the Vietnam Department of Survey, Mapping and Geographic Information can be applied in
most land management surveying tasks such as: (1) Measuring administrative boundary markers at various levels; (2) Surveying the cadastral grid; (3) Surveying level 1 and level 2 control networks; (4) Detailed cadastral mapping in open-sky areas
