In this article, it is proposed to use a hardware and software complex created on the basis of microcontroller technology to record and visualize the parameters of the ship's pitching during an operational voyage. The ability to continuously record the parameters of the keel and side pitching of the vessel in various weather conditions and the changing loading of the vessel allows you to quickly monitor the stability parameters and improve the safety of navigation in difficult weather conditions of stormy navigation. The track recorded in MS EXCEL with the pitching parameters and the current time allows you to compare the recording time with the effect of various hydrometeorological conditions, taking into account both wind and wave effects on the vessel, including from hydrometeorological objects located at a considerable distance from the current position of the vessel. These data make it possible to carry out a harmonic analysis of pitching, to obtain the frequency spectrum, phase-frequency characteristics, proper pitching period and amplitude-frequency characteristics of the vessel.

Problems with ensuring the safety of navigation of vessels in waves and with optimizing the parameters of the vessel's movement currently arise, in particular, due to the inability to use new achievements in navigation of related scientific disciplines, such as the theory of ship pitching, oceanography. This is partly due to the lack of methods for obtaining the spectrum of actual waves in the vicinity of a ship that is on an operational voyage and does not have the ability to make stops to record waves, the absence of ship pitching recorders in the widespread practice of navigation and the lack of software for complex processing of the necessary information. At present, the SGUVT has created software and hardware complexes suitable for use by the full-time crew on ships in operation. Modern software and hardware complex provides the possibility of automated recording of the ship's pitching and its processing. The pitching record can be processed to obtain an amplitude.
