Application of geodetic methods for monitoring of stresses of penstock on Tereblya-Rikska hydropower station

The long-term dependences for the changes of deformations and stresses in penstock based on the results of many-year investigations are established. Such in-vestigations were held on the spatial geodetic network on the Tereblya-Rikska hy-dropower station (HPS). The investigations of the short-term stresses and deforma-tions of the penstock with the use of electronic tachеometer Leica TPS 1201 has been undertaken. Direct correlations between the changes of the length of all baulks and the changes of water level in the storage reservoir are determined ...

The analysis of the results of aerial photography experiments on the basis of a developed UAV model

Modern techniques related to the creation of topographic and cadastral plans of land areas are based on the use of digital data received as a result of aerial photography. This article discusses three core technological issues in the application of UAVs in topographic aerial photography connected to the stabilization of the UAV during the flight: maintenance of a constant speed, maintenance of a straight line of flight and the reduction of tilt. This article presents the results of a study of the aerial photography errors and describes the ways in which the latter can be addressed. ...
