The article describes problems of determining the type and automatic sorting of household waste using mobile computing devices. All of the required hardware and partially software, required for implementation of this service, are already present in modern smartphones.
Objective. Investigate the effect of absolute humidity on the GPS accuracy for different durations of observation. Methods. The GPS observations with different durations over spring-autumn period at 17 permanent stations in France and 8 stations in Switzerland were chosen for initial data. These observations used four GPS networks with a different number of points (from 5 to 8) and lengths of vectors (average length varied from 5.1 to 48.6 km).
Sumatra earthquake was accompanied by the similar strains on four deformation stations. This phenomenon can be explained by the unstable state of geological environment in the field of the future earthquake. It is necessary to use the data GPS side by side with the station data in order to obtain the reliable results.
Purpose. This study assumed: experimental determination of the accuracy of coordinates of points of the geodetic network dual-frequency GNSS receivers from different manufacturers under different conditions of observations using RTK-technology; study connectivity and receiving a fixed solution RTK mode with extra-long bases (200 km). Methods. To investigate the accuracy of the coordinates in the experimental work were involved six surveying crews ukomplektovuvalysya six receivers of different manufacturers.
Purpose. The purpose of this work is to study the possibility of restoring urban traverse networks using high-precision technologies in satellite mode, real-time kinematics. Method. To achieve this goal were involved surveying six teams that were equipped with six receivers of different manufacturers. The observations were made as the "static" and in RTK-mode, and, determining the coordinates of points traverse the network Chernihiv mode performed by permanent RTK networks with different configurations and mount points.
Purpose. The purpose of this work is to study the effectiveness of using satellite technology in real-time kinematics mode for work performed to determine the areas of land of different size within a settlement. Methodology. To realize this рurpose we have conducted experimental research on satellite observation points and triangulation of polygonometry in Chernihiv and the region. During the research it was assumed to get the control coor¬dinates on the basic points from static observation.
