The article proposes to use the territory of the Caucasian Mountain Observatory of the Sternberg Astronomical Institute, Lomonosov Moscow State University, to create a geo-gravi-magnetic test site intended for testing geophysical autonomous navigation systems being developed in the Russian Federation. This test site meets the requirements for a number of parameters. To conduct gravimetric and magnetometric test site measurements, it is proposed to use a fairly wide range of new measuring instruments developed by FSUE ‘‘VNIIFTRI.’’ These include the high-precision relative gravimeter ‘‘Peshekhod,’’ the digital zenith camera ‘‘Astrograv,’’ a quantum level based on highly stable hydrogen quantum clocks and the ‘‘Duplex’’ system, as well as a fluxgate magnetometer. Based on the measurements of the gravity acceleration profiles and deflection of vertical, it is expected to obtain a number of derivative profiles of the EGF parameters. In addition, it is expected to obtain a test site map of the values of magnetic induction and magnetic induction gradients with a resolution less than hundreds of meters.
