GENERAL INFORMATION
The Control Center of the Ukrainian permanent network of GNSS (CC UPN GNSS) is a structural research and production unit of the State Enterprise "Research Institute of Geodesy and Cartography", which in its activities is guided by the orders and instructions of the State Enterprise "Research Institute of Geodesy and Cartography", normative acts operating in the field of topographical, geodetic and cartographic activity and legislation of Ukraine.
Main tasks of CC UPN GNSS
The main task of the GNSS UPN Center is to develop and ensure the functioning of the Ukrainian permanent GNSS network with the aim of:
ensuring the connection of the UCS-2000 State Geodetic Reference Coordinate System with international coordinate systems;
performance of research works on the study of geodynamic movements of the earth's crust;
providing users with geodetic information from GNSS stations when carrying out topographic, geodetic and cartographic works.
Main functions of CC UPN GNSS
Implementation of research and production works on the development of the UPN GNSS infrastructure, including methodical, software, informational, technical and organizational support:
development of methods and technologies for the operation of UPN GNSS stations, server and software, means of archiving and visualization of observation results and publication by means of the Web;
development of methods and technologies for mathematical processing of geodetic observations and their automation;
regulatory support for the functioning of the UPN GNSS;
Development and ensuring the functioning of the UPN GNSS:
monitoring of the state geodetic reference coordinate system UCS-2000;
ensuring permanent communication of the UCS-2000 State Geodetic Reference Coordinate System with international global coordinate systems;
conducting scientific, applied and technological studies of the application of GNSS technologies in topographic and geodetic production;
implementation of tools for monitoring network quality and integrity and quality of service provision.
Provision of geodetic services to users:
provision of subjects of topographic, geodetic and cartographic activity with complete and up-to-date data in the UPN GNSS;
calculation and monitoring of coordinates of permanently operating GNSS stations.
GAMIT/GLOBK software packages, developed by the Massachusetts Institute of Technology (USA), obtained under the rights of free use for scientific non-commercial purposes, and Bernese v.5.4 developed by the Astronomical University of Bern (Switzerland) and purchased in 2021 as part of budget financing. With the help of the mentioned complexes, a visualization system for geodetic monitoring of the stability of UPN GNSS stations was deployed.
The developed system makes it possible to visualize daily determinations of station coordinates and display the stability of the station positions in the UCS-2000, ITRS, ETRS89 coordinate systems.
