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.

Savchuk, S., Polish Air Force Academy, Deblin (Poland) | Doskich, S., Lviv Polytechnic National Univ. (Ukraine)
According to the fast development and distribution of GNSS technologies all over the world, the large numbers of reference GNSS stations have appeared in Ukraine. These stations are included in the state and several private networks. The permanent GNSS observations gathered within these networks are processed and analysed by the Centre of Lviv Polytechnic National University. A cumulative solution (coordinates expressed at the specified epoch and velocities of all stations) was estimated by using the GAMIT-GLOBK software. The authors made several numerous tests using certain configuration of fiducial stations which belong to the EPN A class to transfer ITRF08 frame into Ukraine area and choose the best strategy of alignment of the Ukrainian national GNSS network to the EPN. Three different solutions with cretin tolerance set for Ukrainian GNSS network were estimated and each time the different set of coordinates was obtained. The differences reached several millimetres. Also for verification, our solution was compared with EPN solution. Received coordinates and velocities could have a geophysical interpretation and provide very useful information for local geodesy tasks.

2016
Stoiko, N., Lviv National Agrarian Univ. (Ukraine) | Tkachuk, L., Lviv National Agrarian Univ. (Ukraine)
In Ukraine, degradation of land resources is a complex ecological problem, preventing sustainable development of land employment. Land protection from degradation requires development of measures in the process of land management at regional and local levels. Efficiency of the measures depends considerably on reliable information about quantitative and qualitative conditions of lands, due to the fact that it forces timeliness of the research. The aim of the research is to study problems of land degradation in terms of land management while developing measures of land resource protection. To reach this aim, the following tasks were set out: to analyse the drawbacks of informational support in terms of land management fulfilment at the current stage of land relations development; to describe prospective ways to implement the measures on land protection from degradation in Ukraine. Methodological basis of the research is includes the method of system analysis (performed while studying the process of land resource degradation) and cartographic method (employed while detecting the spread of degradation processes and its drawbacks in land employment). The research has determined that soil maps and plans of employment of lands do not provide reliable information about quantitative and quantitative conditions of land resources. The existing organisation of land use, first arable one, does not always correspond to soil-conserving requirements. It is proposed: to update plan-cartographic material based on space images and data of agrochemical classification of agricultural lands; to establish efficient organisational and economic mechanisms to implement ecological policy in the field of land management.

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.

Land as a production factor occupies a special position in the economic activities of the urban population. Land resources in big cities are not only territorial basis for placing industrial and production structures, but also a space for urban life in general. However, to assess the effectiveness of urban land use, primarily the ecological and economic potential of the use of the urban land resources should be determined aimed at sustainable development of urban agglomerations (Volodchenkov, 2010). The rapid pace of development of large cities in the world and an increase of their impact on the environment and society is accompanied by the set of economic, ecological and social problems which significantly influence the development of settlements in general (Stolʹberh, 2000; Onyshchuk, 2001). However, the process of urbanization as a result of rapid scientific and technological revolution requires large areas for deployment of large scale production facilities and urban settlements in the conditions of natural resource management (Kontorovich, Rivkin, 1986).

Savchuk, S., Lviv Polytechnic National Univ. (Ukraine) | Kalynych, I., Uzhhorod National Univ. (Ukraine)
The national geodetic infrastructure of Ukraine has developed rapidly into Ukrainian Coordinate Reference System UCS – 2000, a fully GNSS compatible coordinate reference system, which is realised through networks of active GNSS stations. They provide data for post processing and streamed raw data for real-time network (RTN) solutions. The RTN raw data are currently being used by both Trimble (ZAKPOS Network), Leica Geosystems (System Solutions Network) and Topcon (TNT - TPI Network) to provide independent RTN solutions. This study is the first in the public domain to evaluate the performance of RTN services in Ukraine and it is intended to provide guideline information for geo-spatial practitioners. Based on collecting RTN data at five locations and using standard observing and processing methods, an accuracy of 25 mm ±10 mm with respect to 2D coordinates and 34 mm ±14 mm with respect to the heights was achieved. The three systems were shown to be generally comparable although some initialization problems were experienced. The result has revealed expected ~2-5 cm (95%) precision for the horizontal and vertical components; however, large horizontal and vertical biases were observed, which can be as high as 8 cm.
