EN
The paper contains a report from studies concerning gravity and position data determination for reductions in the Earth`s gravity field of geodetic and astronomical observations using the horizontal gradient of Poincare-Prey`s anomalies directly in terrain in real time. The author`s indications for establishment of the algorithm of the program GRAWPREY for microcomputer Psion Organiser are given.

Astro-geodetic Observatory of the Institute of Geodesy and Geodetic Astronomy of the Warsaw University of Technology in Józefosław was incorporated in 1957. In 1991 it was joined to the International GPS Service for Geodynamics (IGS) and started to operate as a permanent one in 1993. Since then the following permanent services have been maintained: GPS observations using Trimble and Turbo Rogue receivers, tidal gravimetric observations with LaCoste&Romberg model D gravimeter and meteorological obseryations. Since 1995 WUT Local Analysis Centre, one of the 13 local Analysis Centres acting in Europe, has started the systematic day-to-day processing of the selected number of European sites in the frame of the EUREF network. It processes national and International GPS campaigns (CEGRN, EXTENDED SAGET etc.), models ionosphere and troposphere parameters, compute tidal components and changes of the vertical according to astrometric and gravimetric measurements. For last 5 years the Centre has processed and analysed many of scientific researches carried out in within the confines of the Central European Initiatiye (CEI). This paper presents state of the art of the Observatory's actiyities. It deals with the acting of it and participating of the WUT Local Analysis Centre to the international scientific projects.

Astro-Geodetic Observatory in Józefoslaw is one of the EUREF/IGS sites. In the Observatory there are several continuous observations performed such as: - GPS observatiuns using two receivers; - Tidal measurements witb LC&R gravimeter; - Astrometric observations aimed at latitude changes determinations; - Meteorological measurements. Warsaw University of Technology EUREF Analysis Centre works in the frame of the Observatory. The bank of regional observations is also conducted. The results of the processing of the observations mentioned above could be used to verification of the tidal and non-tidal deformation models that are used in GPS data processing perfomed by WUT EUREF LAC. This paper presents the results of the tidal and astrometric analyses and their comparison to the standard IERS models. U also deals with the non-tidal deformation model comes from the atmosphere in the meaning of the height (GPS) and gravity (gravimetry) corrections.

EN
The processing of the high-precision GPS observations requires a number of models reducing systematic errors. One of the most crucial errors in an ionospheric refraction, particularly its changes and their influence on scale in geodynamic networks. In this contribution we present the methods of ionosphere modeling and their practical application during rising solar activity.
