Geodetic base points

This article presents the iterative weight transformation technique of the problem handle the free geodetic network at Tuyen Quang hydropower. The results showed that the largest displacement value was 2.2 mm/year and equivalent to the actual measurement error. This calculation method provides more useful information about the displacement model of geodetic base points, helping to plan a large-scale project safety assurance.
