The gravimetric network is divided into: Absolute gravimetric network (zero order) and relative gravimetric network (first order). The absolute gravimetric network is composed of three points located in Skopje, Ohrid and Valandovo. The relative gravimetric network is composed of 25 points.
The points of the absolute gravimetric network were determined at the end of 2010 with the most precise absolute gravimeter of the Micro-g-LaCoste FG5 type, with an accuracy of +/-2µGal. The points of the relative gravimetric network were determined in the period August-October 2013 with high-precision relative gravimeters of the SCINTREX CG5 and SCINTREX CG3 types, with an accuracy of +/-9µGal and +/-13µGal.
