The article considers the problem of improving the coordinate-time support of GLONASS, which implies refining the models of a wide range of stochastic error components caused by inaccurate knowledge of geodetic and geodynamic parameters, such as the position and displacement rate of the geocenter, Universal Time, pole shift, irregularities of the Earth’s rotation, precession, and nutation. It is shown that the problem can be solved only using a comprehensive measurement technique that includes the use of various information measurement “techniques,” namely, global navigation satellite systems, quantum-optical communication stations, Doppler velocity sensors, and very-long-baseline radio interferometers. The problem of aligning coordinate systems on which the application of a particular information technology is based that arises from using this approach is discussed. Mathematical models, algorithms, and the results of their development in the experiments on the alignment of coordinate systems used in global navigation satellite systems and quantum-optical communication stations are given. The presented results contain estimates of the misalignment between different coordinate systems, including misalignment by center position and misalignment due to difference in the scale factor and orientation with respect to the inertial coordinate system.
