Overview of the possibilities of satellite-ground survey

      The possibilities of using satellite-ground survey during topographic survey, which is necessary for large-scale mapping, have been reviewed. Global satellite navigation systems are considered. The performed analysis of the choice of methods and instrumentation for the performance of these works.

      Continuous technical development much vpyvaye and replaced removal methods in geodesy. Availability use signals from satellites, land-use facilitated removal of satellite topographical works. This type of removal is much more efficient, more effective and less time-consuming compared with traditional methods of surveying work; makes it possible to conduct topographic and geodetic measurements even without line of sight between adjacent points, since it is based on signals satellites; allows to work in any weather; reduce the impact of atmospheric conditions on observations; allows measurement in areas of limited visibility of satellites through simultaneous use of the receiver at least two major global navigation satellite systems.

      The conclusions show the advantages of satellite-ground survey in comparison with traditional methods of geodesy such as: efficiency, operativeness, low labor intensity in comparison with traditional methods of geodetic work; the possibility of conducting topographic and geodetic measurements in the absence of direct visibility between adjacent points since it is based on signals from artificial earth satellites; independence of work from atmospheric phenomena; allows measurements in areas of limited visibility of satellites, due to the simultaneous use by the receiver of at least two of the largest global navigation satellite systems. In the prospects of the study, the main areas in which it is possible to develop this type of work are indicated.

      Keywords: satellite-ground survey, the global satellite navigation system, GNSS (satellite) receiver.
