In this paper, we discuss the main types of quasiperiodic variations in amplitudes of a reflected signal during vertical sounding of the ionosphere at middle latitudes. The initial experimental data is vertical sounding ionograms obtained by the Cycl

Vertical sounding is a fairly informative method for studying the ionosphere at a relatively small transmitted power. Ones of the incompletely studied phenomena in the F layer are travelling ionospheric disturbances (TIDs). Especially poorly studied

This paper describes the one-board developed digital orientation system for borehole logging tools, based on FPGA, 3-axis magnetometer and 3-axis accelerometer. The FPGA usage be capable of highspeed measurements orientation parameters (~23 Hz), whic
