Absolute gravity measurements in Estonia

The National Standards Laboratory for free-fall acceleration of the Finnish Geospatial Research Institute is measuring absolute gravity values at four points in Estonia in the end of June and the beginning of July.

The points are part of the first order gravity network of Estonia. The Network consists of seven points which the Finnish Geospatial Research Institute first measured as a whole in 2008.

The summer’s absolute gravity measurements are performed with the absolute gravimeter FG5X-221. The instrument is the Finnish national standard for the acceleration of free fall. The gravity values measured with it have a direct traceability to the SI units of length and time.

The work was ordered by the Estonian geodetic measurements company Planserk and is done for the Estonian Land Board.
