摘要
The present article is written in response to the recent call of the United Nations for the enhanced international cooperation of different countries on global geodesy to build the Global Geodetic Reference Frame (GGRF). It reviews historical landmarks in the development of the State Geodetic Reference Frame on the territory of Russia over the last two centuries. It discusses major steps in creating the Russian terrestrial reference frame by both the ground-based and space geodesy methods relying upon the satellite observation techniques. Currently the State Geodetic Reference Frame undergoes a radical improvement in order to effectively implement the potential of modern satellite technologies through the use of the Global Navigation Satellite Systems (GNSS). We outline the current status of the National Geodetic Network in Russia, its hierarchical structure and accuracy. We pay a particular attention to the high-precision State Geodetic Coordinate System (GSK-2011), created simultaneously along with the global reference-ellipsoid, and designed for various types of users to conduct the land surveying and mapping in Russia. We also present the geocentric coordinate system (PZ-90.11) used for navigating space missions, solving various problems of global geodesy, and supporting the continuous operation of GLONASS.
