Аннотация:This work presents the testing results of a new magnetotelluric system NORD. The key features of the system are: wireless operation with options of real-time data processing and quality assessment, measuring complex impedance of electric lines, low self-noise, low power consumption, light weight, compactness, reliability, robust data processing algorithms. The receiver has a built-in calibration system as well as telemetry that
allows to monitor the status of the device and identify common problems. At the moment, the NORD allows to obtain high-quality MT data in the range from 50 000 seconds up to 20 000 Hz. We carried out a large number of field tests and comparisons with equipment from leading manufacturers, which showed excellent performance of the system. Also in recent years, a few large-scale production works have been carried out using this system.
