the automatic operation of the set is presented. This software ensures the temporary binding and calibration of the set and recording of the data on an external streamer. Khudukon B., Evstafjev O., Melnichenko Yu. Automatic mobile equipment for diagnosing the ionospheric inhomogeneous structure using navigation satellite signals. A brief description of the setup and basic technical concepts of a mobile receiving and measuring equipment designed for studying the properties o f the inhomogeneous electron density structures in the ionosphere using coherent signals from Russian navigational satellites is presented. The equipment has been successfully used in measurements performed on the Kola peninsula and in Scandinavia. An example o f analysed experimental data obtained during the tomographic experiment using a chain of 4 spaced identical sets o f the described equipment carried out in Scandinavia in November o f 1995 is demonstarated. The regional system for seismological monitoring of the North-Western Russia and adjacent Arctic areas. Kuzmin I. A., Kremenetskaya E. O., Asming V. E., Kolomiets A. S., Kola Regional Seismological Center, Kola Science Centre of RAN. The paper contains detailed description of the seismological network o f the Kola Regional Seismological Center. A brief overview o f its development is given. Architecture o f the KRSC data processing center is considered. Tokarev A. D., Zhamaletdinov A. A., Vasilyev A. N. Measuring complex SFS-95 for deep soundings of the Earth crust by the control source audiomagnetotellurics (CSAMT). Measuring complex SFS-95, intended for the five-component measurements o f harmonic signals of control sources o f electromagnetic field in frequency range 0.3 - 1000 Hz is circumscribed. A multistage system o f a filtration o f signals with the use reject filters, heterodin system and selective filtering o f intermediate frequency with the following digital form of an entry o f measured signals on the personal computer Note Book is realized. Field trials o f station are spent by measurements o f signals from ELF-antenna at distances up to 1100 km from the source. Kornilov I. A., Kornilov О. I. Data processing system for the videotape recorded information (TV, VLF, magnetic pulsations and so on) System for processing of the videotape recorded data is described. It provides a possibility to digitize and write into the computer memory TV, VLF intensity and spectral data, information on magnetic pulsations and so on. The main principals of the system and developed computer programs are presented. Galakhov A. A. Multichannel device for recording the natural VLF signals under conditions of industrial interferences. A unit o f narrowband filters with frequency conversion filtration is described. The frequency o f electric power network is used for hetherodyn synchronisation 164
