The actual problem of securing the proper functioning of the NGN of Ukraine takinginto account regional peculiarities are studied.The analysis of the state of NGN of Ukraine on the territory of Poltava region by types ofcenters, external geodetic signals, methods of determination of coordinates is carried out in the work.The general problems of functioning of NGN in the territory of Poltava region are established.It is established that in a significant amount of points there are no external geodetic signals.The centers that fix the points of the NGN are represented by more than 40 different types. The centersdiffer in design and size. Some of them are at the same time is references of leveling II category.It is proposed to plan perspectiving measures for the modernization of the NGN on the reasonof the calculation of indicator of regional compliance of the NGN with regulatory requirements forthe density of stations to secure the implementation of topographic surveys. This indicator iscalculated as the ratio of the real amount points in the newly created administrative district to thenormative amount, and is reflected as a percentage. The normative amount is determined on the basisof the area of the respective area and the normative density of stations for the suitable scale of survey.In case of provision of stations at the level of less than 100 % it is necessary to determine theamount of points required to bring the real density in accordance with the normative. Then theexisting NGN needs modernization. Such modernization can be carried out not only in the form of renewal of existing and restoration of lost points, but also through the design and fixation ofadditional points of the calculated number.The analysis of securing of the territory of Poltava region with NGN points for implementationof topographic survey in scales 1:5000, 1:10000, 1:25000 is carried out. Specific proposals toachieve one hundred percent provision of stations in the Poltava region have been developed. Anexample of a possible realization of the respective proposals is illustrated by the design scheme ofadditional stations of the 3 class, developed on the basis of the scheme of the NGN of Ukraine.
