Two radio-science instruments have included into the Luna-Glob and Luna-Resource projects in the frame of Russian Luna exploration program: the lander’s radio beacon and the orbiter’s receiver. Three types of experiments are planned: orbital doppler measurements, VLBI interferometry, and Same Beam Interferometry (SBI). An accuracy of acceleration measurements in the Lander-Orbiter experiment coud be about 3-10 mGal. VLBI and SBI measurements of relative landers distancies with accuracy better than millimeters should give a tool for a accuracy improvement in the following scientific tasks: precise determination of orbital and rotational movement of the Earth and the Moon, determination of mass distribution and internal movements in the Moon’s interior, check of general relativity effects.
