history
Opis:
Astro-Geodetic Observatory in Józefosław, witch belongs to the Departament of Geodesy and Geodetic Astronomy of the Warsaw University of Technology, started to permanent observations in 1958. First of them was time service started in February 1958, coordinated by BIH. From 1959 astrometrial latitude measurements have been done with aim to determine the parameters of the Earth rotation. In 1991 the Observatory was joned to the International GPS Service for Geodynamics (IGS) and started to operate as a permanent one in 1993. There have been performed many observations and scientific researches, such as: GPS in the frame of IGS/IGLOS/EUREF; tidal observations; absolute gravity measurements; changes of the vertical, based on the gravimetric measurements; astrometric observations and metrology. Moreover studies on RTK and DGPS measurements using mobile phone for data transmision are performed since 1998. WUT EUREF Lokal Analysis Centre, one of the 17 Lokal Analysis Centres acting in Europe, is a very important part of the Observatory. The Centre makes continuous service of one-week and daily aolution in the farme of EPN network, 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 measurenents. This paper present history and current state of the art of the Observatory's activites.

Opis:
The paper presents an analytical approach to the determination of power losses in a high-frequency transformer operating in the dual active bridge (DAB). This transformer, having two single-phase transistor bridge inverters, couples two DC circuits that significantly differ in voltages (280 V and 51 V ±20%). Power losses in the core and windings of the planar transformer 5600 VA /100 kHz were calculated taking into account changes in the value and direction of the energy flow between the coupled DC circuits. These circuits represent storage or renewable energy sources and intermediate circuits of the converters used in distributed generation systems. Calculations were performed using the Steinmetz’s and Dowell’s equations. The analytical results have been verified experimentally.

Opis:
In the paper specification of a complex converter designed as an interface between a supercapacitor energy storage battery and other DC auxiliary links, with emphasis on its control system, and some laboratory investigation results, is presented. The converter applied in the solution contains a DC/DC power controller and a DC/AC/DC medium frequency intermediate link with a transformer, permitting good voltage matching. Specific control of both cooperating converters in accordance with the proposed solution gives the possibility of synchronized and phase controlled operation of DC/DC and DC/AC converters resulting in the impact on the AC current wave shape. In this way AC link switching and conducting loss minimize and improving of interface efficiency have been emphasized.

Opis:
This paper presents the implementation of a thermal camera for the quantitative estimation of power losses in a high frequency planar transformer (100 kHz/ 5600 VA). The methodology is based on the observation of the transient temperature rise and determination of the power losses by means of curves representing the derivative of temperature as a function of power losses dissipated in the transformer. First, the thermal calibration characteristics had to be obtained from a simple experiment, where power losses are generated by DC current in the ferrite core and windings. Next, experimental investigations focused on the determination of the transformer power losses for a short circuit and no load, with a resistive load and with the rectifier as a load were carried out. Finally, to verify the obtained results, analytical calculations based on Dowell’s and modified Steinmetz’s equations were additionally made, which showed a good convergence. The proposed method is easy to implement and can be used as an alternative to the calorimetric method which is time-consuming and requires a complicated measurement setup.

Opis:
Geodynamical investigation in the Pieniny Mountain (south of Poland) were carried out since the 1960s. They contained levelling, gravimetric measurements and distance observations in horizontal network. The results reveled vertical and horizontal movements of the crust and periodic changes in gravity. In 1994-1995 horizontal network was adapted to perform GPS observations and they were carried out with leveling, gravimetric and EDM observations. In 1990s, the Dunajec river dam and the water resorvoirs in Czorsztyn and Sromowce Wyżne have been built. This has a new aspect in investigations releted to the effect of tectonic movements on the dam. Taking that into account, the study was revived, after six year break, in 2001. The investigations, which contain GPS, gravimetric and leveling observations, have been carried out every year. In this paper the result of horizontal displacement obtained from GPS measurement as well as gravity changes in 1994-2010 period are presented and yields linear trend in north-east direction less than 1 mm/year.

Opis:
The article presents the results of measurements of gravity performed in the Astronomical and Geodetic Observatory Józefosław. Time series have been verified for parameters related to celestial bodies, atmospheric pressure changes and metrological factors. The analysis of these changes includes geodynamic and hydrological aspects taking into account global and local changes in groundwater levels. The aim of the article is to indicate the interpretation of contemporary measurements of gravity field against the contemporary accuracy of such measurements and to indicate the need for information on the level of groundwater (collected by the Polish Hydrogeological Survey) in procedures for the elaboration and interpretation ofgravimetric measurements and supportfrom hydrogeologists. Contemporary the gravity measurements with use of absolute gravimeters gives possibility determination of gravity value with uncertainty of the order 10-8 ms-2. Such accuracy corresponds to a vertical displacement of a point of less than 1 cm or a change in the water level of 2.5 cm. Use of gravimetric methods in the broadly understood Earth sciences must be supported by information related to changes in mass distribution around the measuring station, mainly related to the groundwater level changes. This allows to see the role of hydrogeological information related to the monitoring of groundwater as an indispensable information describing changes in the Earth’s gravity field.

Presently there are two laboratories in Poland investigating field of gravity. The Geodynamic Laboratory of Space Research Centre in Ksiaz is placed in the south-western part of Poland in horizontal galleries built in slope of the valley. In 1974 in the laboratory the measurements carried out with help of two quartz-horizontal pendulums equipped with photographic system of registration were begun. In 2002 in the laboratory the long water-tube tiltmeter was built. It is consisted of two perpendicular tubes 65- and 83-meter long, partially filled with water. In 2007 in the laboratory the relative gravimeter LaCoste&Romberg G-648 was installed. The Gravimetric Laboratory of Astro-Geodetic Observatory in Józefosław is placed in central part of Poland. It has been investigated tidal gravity changes since 1993 using first LC&R model G gravimeter, then D-model. Since 2001 laboratory is equipped with LC&R ET-26 meter. In 2005 the laboratory was equipped with FG5-230 gravimeter for monitoring of the absolute gravity variations. The paper presents current state-of-art of the researches aimed at investigation on field of gravity carried out by Polish scientific institutions.

Opis:
Gravimetric investigations of the long-standing, not tidal variations of the absolute gravity using ballistic FG - 5 No. 230 gravity meter, bought by Warsaw University of Technology at 2005, were performed on four stations outside the Teisseyre - Tornquist Zone (T - T Zone) as well as at Józefoslaw Astro - Geodetic Observatory of the Warsaw University of Technology, located near Warsaw, near the northern edge of T - T zone on Precambrian Platform. Raw results of observations were corrected by Earth's tide influences, loading effects of the Earth's crust and ocean, by polar motion influence to the gravity as well as from the reason of gravitational and deformation influences of the atmosphere. Monitoring of the gravity on Józefosław station, during three years once a month, pointed out quasi-periodic non-tidal variations. Absolute gravity determinations in previous campaigns (1992 - 2001) on Polish territory were performed using various ballistic gravity meters, many types and quality, as well as there were spread in time. In epochs since 2006 to 2008 with our instrument FG - 5 No. 230 there were obtained the gravity values minor on all investigated stations. It was about 17 žGal on Satellite Lamkówko station, near Olsztyn, and 12 žGal in Borowiec Astro Geodynamical Observatory of the Space Research Centre, Polish Academy of Sciences with comparison to the results from 8 - 10 y earlier obtained using Polish absolute gravity meter ZZG, Italian IMGC and two FG-5 instruments from Austria and USA. The variation since 1996 to 2006 on Giby (station of the gravity national fundamental net) was appeared as only 7.5 žGal. On very stable station Ojców (Seismic Observatory of the Polish Academy of Sciences) located on Świętokrzyskie Mts. craton, the decrease of gravity equal to 9 žGal has been noticed after 9 years. Recovered variations of gravity on Poland territory might have the sources in gravity global or regional variations in the hydrological influences in the vicinity of stations as well as in incorrect earlier determinations of the gravimetric corrections, mainly in vertical gradient of gravity above absolute stations.
