  • Use of Space Facilities for Positioning during Air and Space Information Processing

    Photometric principles of measurements have found a wide recognition and a wide application in different fields of human activity. It is stipulated by the introduction of photogrammetric works of new technology for obtaining primary information about the locality. At present for obtaining high quality and highly exact airophotographic data digital wide format photographic cameras are used and photogrammetric processing of digital pictures is carried out at special digital photogrammetric work stations.
    A great importance is attached to photogrammetric methods during the monitoring of lands for information providing of state realty cadastre. At present land state monitoring is a modern technical trend to provide this cadastre with the necessary graphic and digital documents.
    Photographing of small territories (dacha settlements, agricultural buildings etc.), when the scale of airophotography is ten or more times less than the scale of map-making, is quite possible because the object can be photographed on two pictures that is to be located on one stereo pair. This article is devoted to photogrammetric processing of a single stereo pair. At this space facilities for positioning (GLONASS, GPS) secure the coordinates and altitudes of points of photographic. When space signals are properly synchronized with the work of the photograph camera shutter and careful determination of the elements of adjustment of space antenna to the relative centre of projection (s) of camera is carried out the coordinates of projection centres can be used as supporting geodetic points.
    Point realization of the above-mentioned terms allows to decrease the number of supporting points necessary for outside orientation of model to one. It should be located at the end of stereo pair opposite its middle. While designing redundant supporting points (for control and improvement of exactness) they should be located in the corners of stereo pair.  

    Keywords: photogrammetry, stereo pair, single model, conditions of complanarity and collinearity, elements of orientation, points for photographing, GLONASS, GPS, theory, algorithm.

  • Geopolitical and geocivilizational peculiarities of the Black Sea – Caspianregion in the light of the great limitrophe conception (contemporary context of the question)

    The article is devoted to the problem of the identification of the Black Sea – Caspian region as a special segment of the World Space in the postbypolar system. The Great Limitrophe conception developed by V.L. Tsymbursky and S.V. Khatuntsev is used as «the structural frame» for understanding modern peculiarities of this region. The author outlines two aspects of its identification: geopolitical and geocivilozational. He also introduces the key concept «limitroph territory» adapting it to the specific region. The key concept involves two other concepts – «shatterbelt» and «(inter)civilizational split zone». The article contains brand new facts on the Black Sea – Caspian region problem. 

    Keywords: «big political space», geopolitics, Black Sea – Caspian region, Great Limitrophe conception, limitrophe-territory, «shatterbellt», civilizational layer, «(inter)civilizational split zone».

  • Psychosemantic modeling perception of political order by student of Grozny 2013

    The results of modeling perception psychosemantic political order among students of Grozny in 2013. The study involved 120 people. Modeling based on the classical method of semantic differential Charles Osgood . A comparative analysis of average semantic portraits. Calculated levels of emotional perception of the political order. Perception of order in the Republic: 0, 423052 , Russia: 0.351604 . The basis of the binding model is a theory of two ideal points (extended  method ideal point Coombs ): emotional attitude measured by proximity to the image of the real image of the ideal constructs in semantic space as a whole, rather than individual coordinates. In accordance with the general concepts of "good" and "evil" are calculated ideal "positive" and "negative" constructs. Further, under the theory of catastrophes developed model allows calculations on the ideal proximity to two points. Found that the level of perception described by the potential perception of the fourth degree. A stationary point - stationary states equation of the third degree. Potential itself depends on two factors: evaluation and activity. Based on a group approach, the method of calculation of the binding model and evaluation factors and the activity of the two proximity to two of the ideal points.

  • Experimental research of silicon detector current pulse processing electronic module

    Measurement results of basic characteristics of electronic module based on two specialized analog integrated circuits depending on different square area silicon detectors using source of 239Pu alpha particles is given. Processing of current pulses typically consists to convert them into a voltage by charge sensitive amplifiers and reduce noise by bandpass filters. Earlier for work with avalanche photodiode we have developed, constructed and tested two electronic modules "CRP-MDL-1" and "CRP-MDL-2". During the measurements was investigated spectrometric channel response on exposure to ionizing radiation from a source of alpha particles 239Pu and test input signals, thus we determined basic technical characteristics including energy resolution and noise characteristics. As a result, research found, that the output signal has the following timings: rise time - 1 us (levels of 0.1-0.9), peak time - 1.4 us, fall time - 1.8 us pulse width - 3.5 us. The conversion factor of module working with silicon detector (area of ​​1000 mm2 and a capacity 500 pF) consists about 10.6 mV / fC, or 0.47 V / MeV. Integral nonlinearity of spectrometer path is not worse 0.4% in the range from about 0.1 to 3.2 V. The energy resolution was 89.1 keV line of 5157 keV. The experimental studies revealed that using an external low-noise transistors developed module can be used in the construction of standard radiometric paths. It is appropriate to use the developed design-circuit solutions for implementing 4-channel chip for multi-channel radiometric and spectrometric systems.

  • On about the features of UAV control systems with flapping wing

    In the article a number of approaches to a flapping wing pilotless vehicle control system synthesis are analyzed. Referred type of pilotless vehicles is possessed of a number of advantages compared to the traditional schemes, but requires a special approach to control system creation because of strong nonlinearity and multicoupling of a controlling object mathematical model. As a result of a control system synthesis approaches analysis a synergetic approach was marked out as the most adequate for the mentioned above type of controlling objects. An idea of prognostics application for the goal of reaching of adaptive control is also set forth. In this case parameters of an object of control and parameters of ambient both are to be forecasted whereby an adaptive behavior of an object of control is expected to be achieved.

    Keywords: control system, pilotless vehicle, control theory, “barrier of dimensionality”, synergetic approach, adaptation, prognostic.

  • The loosely coupled algorithm of integrated INS-GPS navigation system of the vehicle

    The existing approaches to the integration of relatively cheap strapdown inertial navigation system (SINS) based on MEMS-based technology and satellite navigation systems (SNS) are ineffective in relation to motor vehicles. We consider the iterative algorithm for the loosely coupled mode of integration of heterogeneous navigation systems do not intend to use the optimal estimation. The solution is obtained on the basis of the fully nonlinear model of the navigation system of the vehicle and the, therefore, is valid for arbitrary and unknown in advance nature of his movements, and, in the most general assumptions about the level of disturbances acting upon him.
