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.
