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.

This paper presents an experiment involving the processing of observations using the GPS and GPS/GLONASS systems performed at the BOGO, BOGI, and JOZ2 IGS stations. Due to the small number of GLONASS satellites, the authors failed to receive any significant improvement in positioning accuracy using GPS and GLONASS observations jointly.

The practical need for GNSS positioning in real time led to the development of a medium for data transmission. DGPS correction data can be transmitted over an area of several hundred square kilometers using longwave radio frequencies. The RTK technique needs greater radio line throughput capacity as well as shorter distances between ground based reference stations. The RTK data from the reference stations can be transmitted through the DARC system by local stations using UHF channels, but the local stations in Poland are not interested in the propagation of RTCM data. The authors present test results of RTK and DGPS measurements using data transmission by Internet and mobile phones. The rover user is equipped with a GPRS (General Packet Radio System) modem in a GSM phone, which is connected to a laptop computer or receiver controller with special RTCM Client software that receives the RTCM data stream from the server via the TCP/IP protocol and transmits it via the serial port to the rover GPS receiver. The new Polish EUPOS–ASGPL active control network allows the use of the RTK technique with a practical range of ten nautical mile in Poland’s inshore area.

Ortofotomapa w postaci cyfrowej na naszych oczach staje się standardem dla wielu współczesnych opracowań geoinformatyki. S1P jest najlepszym przykładem. Coraz powszechniej sięgamy po cyfrowe ortofotomapy lotnicze bądź satelitarne. Kartometryczne wartości tych opracowań są bardzo często znane jedynie z raportów samego procesu korekcji ( na punktach dostosowania bądź punktach kontrolnych ). A jak wygląda faktyczna kartometryczność tych opracowań ? Wydaje się, iż jedynie niezależnymi metodami weryfikacji terenowej można dać odpowiedz na to pytanie. W poniższym opracowaniu zostanie zaprezentowany przykład takiej weryfikacji cyfrowej ortofotomapy z wykorzystaniem pomiarów GPS. Przebadano trzy fragmenty arkuszy ortofotomapy uzyskane z panchromatycznych zdjęć satelitarnych IRS o wielkości terenowej piksela 5.8 m., które zostały zakupione dla całego obszaru Województwa Mazowieckiego. Badana ortofotmapa opracowana została przez GeoSystems Polska przy pomocy oprogramowania ERDAS.

This paper deals with different application of RTK-GPS methods for precise monitoring of the moving objects of different kind. The high accuracy of this method (which actually reaches a few centimetres) makes the possibility for much wider application as used until now. The authors performed the tests aimed at the investigation of the RTK measurements accuracy made in critical conditions (obstructions, multipath, etc.). This paper describes results of such tests, which were performed using manmanned models of VLLC in Warsaw and practice determination of the accuracy of the real-time kinematic GPS. It also presents the contemporary methods of the multipath elimination and the results of their practical application.

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.

This paper deals with different application of RTK-GPS methods for precise monitoring of the moving objects of different kind. The high accuracy of this method (which actually reaches a few centimetres) makes the possibility for much wider application as used until now. One of such usage could be the simulation and monitoring ship's slow speed manoeuvres, tested by the authors. It describes results of such tests, which were performed using manmanned models of ferry and VLLC in Ship Handling Research and Training Centre in Iława, Poland and practice determination of the accuracy of the real-time kinematic GPS. One of the objectives of this paper is to recommend the kinematic method, by both the position in real time and postprocessing mode to use in moving objects monitoring. The current state of the telccommunication links allows us to build some kind of tracking system for moving objects monitoring in quasi-real time. The paper also discusses the optimal localisation of the base stations dedicated to such a monitoring system for Warsaw.

The Processing Centre at the Institute of Geodesy and Geodetic Astronomy, Warsaw University of Technology (IGGA WUT) was established in the early 1990s. In 1992 it started data processing of large geodetic networks, including EXTENDED SAGET frame which was observed on yearly basis over the years 1992-1998. CERGOP Processing Centre was set up in 1994. The Centre performed data processing of the successive campaigns conducted annually in the years 1992- 1997 on the CEGRN frame established within this project. Since the early 1995 tests on computation strategies were performed in cooperation with the CODE Centre in Bern. The tests were later used for the IGS pilot project on the densification of ITRF through a regional network data processing. In 1996 the WUT GPS Processing Centre became one of the European Local Analysis Centres operating within the framework of EUREF (WUT EUREF LA C). The Centre performs systematic data processing for a selected number of permanent stations, which participate in the EUREF permanent network. For several years now research and works have been conducted on continuous monitoring of the ionosphere and troposphere and on modetling geophysical phenomena for the GPS needs. The local model of deformations will be developed by combining tidal gravimetric data, regional meteorological data and a cycle of observations of the latitude changes conducted for a period of over 40 years and processed in HIPPARCOS system. This paper presents current state of the art of the Centre's activities.
