Opis:: The paper presents application of the GPS - Thales Mobile Mapper satellite navigation receiver for conducting the direct underwater inventory and location of objects on the bottom of inland water reservoirs. The design description of the measurement set consisting of the manual GPS/GIS receiver, specialist watertight casing with function keys and floating GPS antenna is presented. The possibilities of using the set directly in underwater navigation conducted by a scuba diver on shallow depth were investigated. The results of search for obstacles located earlier using the hydroacoustic methods: the single beam echo sounder (SBES) and sidescan sonar (SSS) were described. The analysis of accuracy of the underwater GPS navigation was also conducted.

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 sequential method of integrating navigartional parameters obtained from non-simultaneous navigational measurements is presented. The proposed algorithm of position coordinates estimation is general and includes two modes of data processing - from simultaneous and non-simultaneous measurements. It can be used in hybrid receivers of radionavigation systems integrating non-homogeneous position lines or in integrated navigation systems, particulary in receivers combining the measurements of various satellite navigation systems.
