Opis:
The paper presents attempt to find the answer to the question, if the experimentally functioning in Matopolska and Silesia system of reference stations is useful to determine geodetic coordinates, using real time technology when the final result of the measurement is known immediately. To obtain the aim multiple measurements were performed using the RTK-GPS technology on selected points of the POLFER network using corrections generated by the System. On a basis of empirical results of measurements, the evaluation of the usefulness of the system for geodetic applications was performed. Reference stations network of the system ASG-PL which was tested, is one of the so called terrestrial differential systems aiding measurements GPS-RTK (real time kinematic). Networks of the type are very often build in different countries and have national or even continental character.

Opis:
The paper presents the results of positioning by means of the RTK (Real Time Kinematic) method under forest conditions. The experiments were conducted over four consecutive days on hours when the configuration of GPS satellites over the test point was optimal. During the tests a Z-Xtreme receiver by Ashtech was used. On the first and the last day the corrections from the reference station were transmitted to the mobile receiver using the NTRIP application and on the other days the radio modem by SATEL was used for transmission of the corrections. The accuracy of measurement point coordinates in the GPS/RTK is expressed in centimeters; however, achievernent of that accuracy of results under forest conditions is highly difflcult as a consequence of the problem with ambiguity determination by the mobile receiver. Additionally, the mobile receiver is reached by GPS signals disturbed by signal multipath and cycle slip errors. The experiments presented in this paper indicate that despite very difficult measurement conditions it is possible to determine the coordinates of points under forest conditions with the accuracy of a few centimeters.

Opis:
The survey technique using satellite navigation methods have already reached such level, that it can be used not only for position determination at any place on earth but they have the quality which makes it possible to take actions at higher demands in regard to thc accuracy. Such field of potentlal implementation is displacement survey especially at vast areas where classic methods based on angles and distances don't guarantee sufficient accuracies of the results. In regard to increasing possibilities of RTK technique, some tests of its accuracy have been performed in different places, which showed the reality of reaching standard deviation in less than 1 cm. Such assessment encourages to attempt the use of this techniąue to ineasure displacements. As a part of this work the methods for obtaining accurate results with RTK technique have been reviewed, our own procedure for measuring and calculation has been developed and series of tests have been performed along with a study of their accuracy. Factors which affect the accuracy of the measurement time were examined among others, the number of reference stations approximations and observations filtering, and the differential adjustment. The conclusions provide prospects for achieving the accuracy of the measurement of horizontal displacements of large objects with the average error of 2-3 mm.

Opis:
The paper presents the application of RTK technology for measuring the horizontal and vertical cross-sections of the Nysa Kłodzka River located in the southern part of Poland. GPS measurements were performed by the staff of Chair of Satellite Geodesy and Navigation of University of Warmia and Mazury in Olsztyn in cooperation with the team of the OPeGieKa Wroclaw company. The measurements had been done for 30 days during August and September 2004. Three GPS receivers were used such as two Ashtech Z-Xtreme and one Ashtech Z-Surveyor. The radiomodems Satelline of SATEL company were used for transmitting RTK corrections from a reference station to rovers. RTK measurements were being performed in very difticult observational conditions Iike in heavy shrubbery or under trees. It was excellent occasion to test reliability and accuracy of RTK positioning in practice. In general, the use of RTK technology in woodlands and rural terrain extremely improved efficiency of works, but gross errors were being occurred from time to time in very severe conditions of GPS observations due to the lack of good satellite geometry and availability.
