Results of 24h real-time network (RTN) measurements performed at the same time on two positions with 60 seconds sapling intervals were the subject of analysis. These measurements results were determined on the basis of VRSnet.pl being commercial network of reference stations as well as Małopolski System Pozycjonowania Precyzyjnego (MSPP) which in turn is part of the national ASG-EUPOS network. The absolute error and uncertainty of point position for each observation were computed. Subsequently, uncertainty of point position was compare with values of three dimensional Root Mean Square (3D RMS) which in turn were determined using algorithms of selected systems. Measurements using the RTN method can be used to quickly collect information about the location and geometry of objects for field studies.

The objective of this paper is computation of the corrections to sea level anomaly data due to center of Earth mass variations. The geocenter motion model was computed from the center of mass coordinates data determined from observations of space geodetic techniques such as Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS) and Doppler Orbitography and Radiopositionig Integrated on Satellite (DORIS). In order to compute the geocenter motion model the center of mass coordinates data were filtered using wavelet based semblance filtering which allows computing a common signal in two time series. Based on determined geocenter motion model a correction to sea level anomalies (SLA) data due to geocenter motion was determined. This kind of correction to sea level anomaly data is of the order of few millimetres and should be applied to altimetric measurements to refer them to the International Terrestrial Reference Frame (ITRF) Origin considered as the center of figure.

In October 2010 the US Naval Observatory together with the Space Research Centre in Warsaw initiated the Earth Orientation Parameters Combination of Prediction Pilot Project, which was accepted by the IERS Directing Board. The goal of this project is to determine the feasibility of combining Earth Orientation Parameters (EOP) predictions on an operational basis. The ensemble predictions of EOPs are more accurate than the results from individual predictions. The pole coordinate data predictions from different prediction contributors and ensemble predictions computed by the U.S. Naval Observatory are studied to determine the statistical properties of polar motion forecasts by looking at second, third and fourth moments about the mean. The increase of prediction errors in pole coordinate data can be due to the change of phase of the annual oscillation in the joint atmospheric-ocean excitation function.

Przedstawiono wyniki badań przeprowadzonych w gospodarstwach Małopolski dotyczących pozyskiwania przez rolników informacji o maszynach rolniczych. Badane gospodarstw podzielone były na: warzywnicze, sadownicze i prowadzące produkcję tradycyjną. W pracy porównano sposoby zdobywania informacji rolniczej w wymienionych grupach.
