Development of a methodics for improving the accuracy of determination of spatial coordinates of object points during air surveillance from a UAV

Purpose.  Develop an optimal algorithm that will increase the accuracy of determining the coordinates of the terrain when using the aerial process applying an unmanned aerial vehicle (UAV). Method. The minimization of function based on the condition of collinearity is performed, which clarifies the elements of external orientation (EZO) of digital images and leads to an increase in the accuracy of the spatial coordinates of the points of objects.

Method for structural optimization of avionics of unmanned aerial vehicle

This paper presents an approach for identifying the optimal configuration of avionic systems of the unmanned aerial vehicle (UAV) based on an additive multi-attribute utility function.  The function arguments are technical and economic indicators of avionics design quality that are specified in accordance with the UAV requirements.  The method is developed on an improved decision model that has a high degree of adequacy primarily by the increasing number of the utility attributes and using advanced reliability models of avionic systems.  These reliability models consider in addition to the

MEASUREMENT OF COORDINATES OF UNMANNED AERIAL VEHICLE RADIO BEАCON

An experimental system for measuring the parameters of the flight trajectory of its own object-radio beacon, in particular, in the unmanned aerial vehicle (UAV) is developed and tested. Passive radio-location system is used. The difference-phase, difference-time and difference-frequency methods are compared. The first one provides the sufficient precision, not more than 1 deg. in the range of 30 to 140 deg. The phase measuring device is based on chip AD8302, operating at the frequency range up to 2.7 GHz.

Research of the attitude data correction method for the UAV remote sensing images of inaccessible areas in landscape architecture

As an important way to obtain the high-resolution remote sensing images, the unmanned aerial vehicle (UAV) aviation remote sensing plays a more and more important role in the area of photogrammetry and remote sensing application. The correction of the UAV remote sensing images without the ground control points needs high-resolution attitude data. The original attitude data can be obtained from the UAV airborne GPS/INS.

Analysis of modern methods surveying in the processing large-scale plans

Aim. Analysis modern methods surveying of processing large-scale plans. Method. Creating large-scale plans is an important task in mapping Ukraine because the existing topographic plans eventually need to be updated because it no longer meets the current state of the area. The scope of large-scale plans are diverse: the development of general plans of cities and rural areas, landscaping and engineering training areas of cities and towns, drafting drainage and irrigation of agricultural land cadastre settlements and so on.
