Abstract

This article defines the requirements for the architecture of the planned state satellite geodetic network, mathematical models (used in the processing of GPS measurements), navigation modules and analyses the possibility of integrating the high-precision geocentric coordinate system of the Republic of Kazakhstan with the global terrestrial system of the ITRS / ITRF. The main goal in solving problems of high-precision satellite geodesy is to determine the exact coordinates of the SGN point by processing code or phase measurements (or combined ones) coming from several navigation satellites of different systems (GLONASS / GPS / GALILEO). The article provides two possible variants of the development of the reference system of the Republic of Kazakhstan and identified as the positive aspects, and the disadvantages of these options. As reference systems for the development of the Kazakhstan Earth Reference System, two main systems PZ-90.11 and WGS-84, consider revising. The values of the transition parameters for the new coordinate system and the redefinition of the position of the points of the geodetic network of the Republic of Kazakhstan are given.
