Abstract
On the Role of Glonass for the Development of the Russian Geodetic Reference NetworkThe combined use of GPS and GLONASS satellite systems is a main technology for the development of the fundamental geodetic network in Russia and for crust movement studies along the North Eurasian tectonic plate. All permanent stations of the state fundamental geodetic network will be provided with the two frequency GPS and GLONASS receivers. A collocation of these stations with the existing Russian sites of the international GNSS (Global Navigation Satellite System) network is foreseen. The GLONASS state program foresees to come to 18 satellites in constellation in 2007-2008, and full operation capability (24 satellites) will be reached by 2009. The second generation of satellites: GLONASS-M have the L2 civil signal, extended lifetime and improved clock stability. GLONASS-K satellites are expected by 2009 with the L3 civil signal and Synthetic Aperture Radar function. A combination of GPS and GLONASS will benefit the scientific geodynamic research and practical users, especially in the urban, mountain and near polar areas. Results of the experimental GLONASS data analysis performed. Comparison of mean values of coordinates from only GLONASS solution, obtained at the Institute of Astronomy (Moscow) with the use of GIPSY-OASIS2
Highlights
The combined use of GPS and GLONASS satellite systems is a main technology for the development of the fundamental geodetic network in Russia and for crust movement studies along the North Eurasian tectonic plate
The State concept of the Russian United Positioning, Time and Navigation Service was approved in October 2004 by the Federal Government and corrected by the President in January of 2006
The third civil signal at L3 frequency will be included in the new generation of spacecrafts “GLONASS K”, as well as better solar panel pointing of 1degree and SAR function
Summary
An establishment the present-day heterogeneity of the Eurasia was one of the most significant achievements of regional geodynamics during last decade. Studies of the seismic belts of Eurasia and velocities of the crust movement, estimated with the use of GPS measurements at the sites of the international GNSS network, showed that only a northern part of the continent could be classified as an indivisible lithosphere plate (Gatinsky, et al, 2005) It could be named the North Eurasian Plate unlike the Eurasian Plate, which doesn’t exist as an indivisible tectonic element. With the purpose of improving the national geodetic reference frame an establishment of the new Fundamental Astro-Geodetic network (FAGN), based mainly on the combined use of GPS and GLONASS measurements, is carried out in Russia, under the management of the Federal Department of Geodesy and Cartography in collaboration with the Academy of Sciences. The FAGN will consist of about 40 fiducial sites in 700800 km distance each other and equipped with dual GPS and GLONASS receivers. (Kuzin et al 2007)
