The current results of studies performed within the framework of the complex task of improving domestic systems of high-precision instrumental observations using the Geophysical Laboratory of the IPE RAS in the North Caucasus are presented. The laboratory is located in the vicinity of the Mt. Elbrus in a deep underground tunnel of the Baksan Neutrino Observatory, supervised by INR RAS. Instrumental complex consist from the main instrument unique a two-axial tiltmeter and the data acquisition, processing, and storage systems. Also, there are installed round-the-clock monitoring of the parameters of the environment around the tiltmeter, including precision measurement of the temperature of the ambient air, the pedestal and body of the tiltmeter, the measurement of humidity and atmospheric pressure. In addition, the highly sensitive and eye-safe LIDAR system is helped to monitor the aerosol emitted by cracks at the installation site of the complex. During this year, a set of works was also carried out to ensure the design spatial position for a precision installation of geophysical measuring equipment. The achieved orientation of the actual position of the pedestals was made with an accuracy of ±00°02'.
