Due to the fact of the necessity of state geodetic net modernization (SGN) of the Republic of Kazakhstan (RK), which was created in the coordinates system of the year 1942 (CS-42), vital questions were raised by the initiative group of scientists and specialists of Russia and Kazakhstan concerning geodetic net modernization in the Republic of Kazakhstan with the use of global navigation satellite systems (GNSS) GLONASS and GPS. The first discussion of the problem took place on 5th-8th of June 2012 in Astana during business meeting in the State Republic Enterprise “Kazgeodesy”.
The magazine “Geoprofi”, starting from the number 6 of the year 2012, proceeded to the articles publication concerning this issue. The leading scientists and specialists of Russia and Kazakhstan were working on these articles, including specialists of RPGE “Meridian+” LLC: V.K.Andreev, Head of the Geodesy department, Candidate of Science; U.D.Samratov, Adviser of Director General, Candidate of Science; V.V.Khvostov, Adviser of Director General, Candidate of Science.
The main purpose of the publications is drawing of specialists’ attention from Russia and Kazakhstan to the issues which were pointed out in the articles and extensive discussion of the main points of SGO RK modernization, which involves implementation of the state geodetic system/ RK net, state levelling system/ RK net and state gravimetric system/ RK system, which rely on the all-terrestrial spheroid characteristics and the Earth gravity field PZ-90.11 (Russia).
During the conversation were suggested the most perspective and beneficial methods and high-accuracy technologies of the determining of coordinates and heights of 3D objects with the use of global navigation satellite systems GLONASS (Russia), GPS (USA), the combinations of geometric and satellite levelling and also absolute and relative determination of the gravity acceleration.
Research-and-production geodetic enterprise “Meridian+” Limited Liability Company is one of the leading Russian companies which since 2000 specializes in the performance of digital aerial survey, laser scanning, topographic-geodetic, hydrographic and land planning works, complex engineering survey and land assessment.
