Pododdziały rozpoznania artyleryjskiego są organicznym elementem struktury oddziałów artylerii, które odpowiadają za ich specjalistyczne przygotowanie i wyszkolenie oraz za prawidłową eksploatację środków rozpoznania. Podczas wykrywania celów, w ramach wykonywania zadań bezpośredniego wsparcia ogniowego, rozpoznanie artyleryjskie jest podstawowym źródłem wszelkich informacji, wykorzystywanych na potrzeby ognia artylerii.

Six-year cycles of the pseudo-periodical oscillations are discovered in the series of astrometrical observatioos of the latitude and universal time, tidal observations and Earth rotation series. The variations of the latitude with period about 6 years are.due to oscillations of the local vertical. At observatory Washington the 6-year oscillations of the vertical for the period 1919-1953 are with amplitude 20-30 mas and 5.5-year oscilIations of the vertical at observatory Plana are with amplitude about 10 mas for the period 1987.5-2005.3. A part of the last oscillations are highly correlated with the 5.5 year cycles of nontidal changes of the gravity at observatory Brussels with amplitude 50 nm/s**2, determined from superconducting gravimeter measurements. ln the case of even distribution of the gravity effects, due to the six-year oscillations of the Earth, the corresponding depth of the resulting central 'force of the disturbances (pendulum model) will be about 600 km. The residuals UTO-TAX of the approximation of the universal time observations at observatory Washiogton consist of several 6-year cycles for the period 1953-1992. The Singular Spectrum Analysis of the LOD series from the solution C04 of the IERS shows the presence of six-year oscillations for the period 1962-1987 and no existence of six-year oscillations after 1987. Some of the six-year oscillations are with close phases. Probably the six-year oscillations of the gravity are due to the core-mantle interactioo aod correspoodiog redistribution of the heavy and light masses in the mantle convective flows and these oscillations are observable on the Earth surface but they affect very insignificantly the Earth rotation. These results are obtained in the frame of Joint research projects between scientific institutions of the Academy of Sciences of three European countries - Republic Bulgaria, Czech Republic, and Russia.

Horrebrow-Talcott method observations of latitude changes have been performed in WUT Astrogeodetic Observatory in Józefosław since 1959. Results were recalculated using positions and proper motions from HIPPARCOS Catalogue and present IAU standards because of errors in declination corrections and Iow accuracy of proper motions from old catalogues. Quality of data has been distinctly improved. The value of micrometer screw revolution was also corrected. Now there are no magnification of annual term with time. We calculate subsequently mean latitude, theoretical (so called "calculatio") latitude, 0-C term and main periodic terms in both). We gain mean latitude, secular trend, annual and semi-annual change of 0-C term and precision assessment. Residuals were object of spectral analysis in search for long term and seasonal part. This paper presents preliminary results of such computations.
