Kalna-Dubinyuk, T., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine) | Isachenko, A., State Univ. of Land Use Planning, Moscow (Russian Federation)
Consulting is a catalyst for scientific and technological progress in agriculture, promotes the dissemination of new knowledge, and is quite reasonable and necessary in the current socio and economic conditions. Organization of a system of land use planning - one of the main areas of regulation of land relations in the ongoing land reform. Training of specialists in the field of land use planning should include consulting and component for diffusion of innovation in achieving sustainable development of territories and effective use of agricultural land. The article concentrates on experience in consulting education at the National University of Life and Environmental Sciences of Ukraine and its using based State University of Land Use Planning in Moscow.

Remote monitoring of the atmosphere is designed to obtain information about the state of the atmosphere. The principle of the remote monitoring system of the atmosphere is based on the registration and processing of spacecraft radio signals of the Global Navigation Satellite Systems (GNSS). The wet tropospheric delay component of the electromagnetic signal (Δρ sup(tropo) sub(w)), which is derived from the GNSS observations data analysis, is used to calculate the water vapour content in the atmosphere. It is well known, that this parameter is critical to meteorologists, because the water vapour content in the atmosphere is a key parameter in the construction of numerical weather modelling. In this article the IWV - Integrated Water Vapour has been estimated and the expected accuracy of its determination on the basis of the operational GNSS data processing from reference station network ZAKPOS and the results of aerologic sensing of the atmosphere are given.

2017
Liubov Yankiv-Vitkovska, L., Lviv Polytechnic National Univ. (Ukraine)
The results of the determined ionization identifier TEC (Total Electron Content) for continuously operating reference Global Navigation Satellite Systems (GNSS) stations are analysed. On the one hand, the data reflect the state of the ionosphere during the observation; on the other hand, it is a substantial tool for accuracy improvement and reliable determination of coordinates of the observation place. It was decided to solve a problem of restoring the spatial position of the ionospheric state or its ionization field according to the regular definitions of the TEC identifier, i.e. VTEC (Vertical TEC). We have described one possible way of solving this problem, which is based on mathematical modelling by using degree polynomials and trigonometric Fourier series. Degree polynomials describe the trend of function, whereas the trigonometric Fourier series are used in order to better simulate the fluctuation. The method was tested for network of permanent stations ZAKPOS.

2017
Perovych, L., Lviv Polytechnic National Univ. (Ukraine) | Begin, S., Ivano-Frankivsk National Technical Univ. of Oil and Gas (Ukraine)
This article is concerned with the problem of establishing process equipment deformation regularities, in particular, gas engine compressors at the compressor station of underground gas storage facility in Bohorodchany due to ground topographic surface vertical movements caused by gas flooding into and extraction from the reservoir bed in different seasons. Values of longitudinal and lateral pitches of gas-engine-compressor units’ foundation plates were determined using the results of topographic surface vertical movements monitoring. This provides an opportunity to predict adverse processes in gas engine compressors operation. On the other hand, this monitoring facilitates resolution of land resources sustainable and efficient use issues at underground gas storage territories.

2017
Khoptar, A., Lviv Polytechnic National Univ. (Ukraine)
The role of space geodetic techniques combination is becoming increasingly important to calculate the geodetic parameters. It has an intention of using the advantages and complementarity of different techniques to achieve the best solution. Estimation of geodetic parameters from observations mainly was done by least squares adjustment within the Gauss - Markov model. The combination can be done at three different levels: observations, normal equations and parameters. This article analyses the differences between the approaches and discusses the possibility of troposphere parameters calculation from a theoretical point of view.

2015
Dudych, H., Lviv National Agrarian Univ. (Ukraine) | Dudych, L, Lviv National Agrarian Univ. (Ukraine)
The main peculiarities of land relations abroad are highlighted in the article. Basic principles of foreign experience of land use regarding market circulation of land, concentration of major land resources by right of ownership as well as the process and ways of reformation of land relations are generalized and systematized. Some peculiarities of lease relations, collection of rents and restrictions on title to land for foreigners are analysed. Some positive aspects are distinguished in order to use them in Ukraine. Some ways of improvement of land legislation in Ukraine are suggested taken into account foreign experience.

Trevoho, I., Lviv Polytechnic National Univ. (Ukraine) | Riabchii, Valeri, National Mining Univ., Dnipropetrovsk (Ukraine) | Riabchii, Vladyslav, Lviv Polytechnic National Univ. (Ukraine)
The current situation in land leasing in Ukraine is analysed, when a tenant of a land parcel with immovable property is sold in part, which causes the following controversy: the land parcel in someone’s lease has buildings or constructions owned by another physical or legal person (other than the tenant). The interested party wastes a lot of time on resolving this controversial situation with the existing procedures in Ukraine. This problem is not always solved professionally because of the lack of sellers’ and buyers’ knowledge of specific features of land management and geodesy. Three main variants of mutual location of the seller’s and the buyer’s buildings and constructions are defined, which determines the possibility of dividing a land parcel. Recommendations on the improvement of the procedure and normative legal acts of Ukraine concerning the issue are developed, aimed at significant acceleration of signing and registering new lease agreements.

Kablak, N., Uzhhorod National Univ. (Ukraine) | Reity, O., Uzhhorod National Univ. (Ukraine)
The remote monitoring of atmosphere is designed to obtain information about the state of atmosphere. The principle of the remote monitoring of atmosphere is based on registering and processing of GLONASS/GPS radio signals. Modern networks of active reference stations allow us to solve both practical problems of geodesy, navigation, and purely scientific problems that are important in all geosciences. We propose to explore the existing infrastructure of national networks of active reference GNSS stations for remote sensing of the atmosphere in order to determine the water vapour content in the atmosphere as one of the major factors affecting weather.

Bavrovska, N., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine) | Boryskevych, O., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine)
One of the primary measures of the land reform is to create the national land registry and related land information database, which can be formed only through a complete inventory of land. This article analyses land inventory data in the current stage of land cadastre functioning and development of land relations, as well as discusses justification of organizational and legislative preconditions for land inventory in Ukraine.
